Professor Rob Atkin

ARC Future Fellow

School of Environmental and Life Sciences (Chemistry)

A cleaner future powered by chemistry

Professor Rob Atkin collaborates with partners across Europe and the USA to be at the forefront of energy-efficient working fluids.

Professor Rob Atkin has always been fascinated by the natural world, and has a deep-seeded desire to understand "how things work". Atkin modestly admits that chemistry was not his best subject in high school but he became passionate about the subject as he came to understand its role in shaping the future of the planet.

As a recipient of an ARC Future Fellowship at the University of Newcastle (UON), Atkin has emerged as a leading physical chemistry researcher with a strong commitment to teaching. In his current research at the world-class Newcastle Institute for Energy and Resources (NIER), Atkin focuses on materials that will have economic and environmental benefits across multiple industries.

"At the moment I'm concentrating on developing new working fluids – battery electrolytes, intelligent lubricants, solvents for biofuels and in bioreactors – which are high performing and more environmentally friendly than currently used materials. We are doing lots of work with ionic liquids and deep eutectic solvents."

The goal of Atkin's group of 15 researchers is to develop the next generation of smart materials to produce high value products.

"There's a lot of potential for industrial and engineering collaborations in the electronics and automotive industries, medical devices, and so on... I'm also interested in developing processes for turning coal in to a more environmentally acceptable fuel".

Rob AtkinWhile Atkin's research addresses real world problems, it is built on a foundation of fundamental research, a systematic method of study that looks at the building blocks of science and facts prior to practical applications.

"The deep understanding that comes from fundamental research produces quantum leaps in performance that are not usually possible when trial and error approaches are employed".

Collaborative relationships play a key role in Professor Atkin's work globally with long-term partners in Sweden, Germany, the UK and, increasingly, in the USA.

"Forging strong industrial collaborations in research is a current objective and we are seeing increasing interest from forward-looking commercial partners who understand the benefits of research."

Professor Atkin believes being an active researcher and collaborator also gives him more to offer his students.

"The students who choose to come here really do come here to learn and work. The students we produce are globally competitive. The University of Newcastle offers exceptional education and support."

Throughout his career, Professor Atkin has maintained constant funding support from the Australian Research Council, published over 90 journal articles that have received almost 4000 citations, and is highly regarded for his work in atomic force microscopy and neutron scattering.

Finding the right chemistry

Associate Professor Rob Atkin is making an important contribution to the development of better and potentially greener industrial liquids.

Rob Atkin with a beaker of liquid 

As a former basketball player, Associate Professor Rob Atkin knows that executing an 'assist' can sometimes be as valuable to a team as scoring a basket. It is an important lesson for a researcher in a vast and rapidly expanding scientific field where every new discovery is a step towards a more energy-efficient and environmentally friendly future.

Atkin, a physical chemist, conducts research that contributes to the development of novel room-temperature ionic liquids, or molten salts. These are vastly under-exploited substances that can be used more effectively than existing liquids in a range of industrial applications, including lubrication, catalysis, heat transfer and electrodeposition.

"Table salt melts at about 800 degrees Celsius, so if you heat it up enough it turns into a liquid," Atkin outlines. "What we do is take similar salts, change the molecular structure and manipulate them so they have melting points below room temperature. Once you have something that is pure salt but is a liquid, it can do all sorts of interesting things."

As well as offering greater efficiency, these so-called 'designer salts' hold the promise of being cheaper and greener alternatives to conventional solvents – and as pure electrolytes have useful conductive properties. Atkin's focus is on gaining a better understanding of the basic science of this growing field, and identifying the fundamental relationships between properties and the molecular structure of ionic liquids.

"The Holy Grail is being able to match the properties of an ionic liquid to a particular application," Atkin says. "That might sound simple, but the catch is that there are theoretically billions of different ionic liquids – only about 3,000 of which have been described in literature.

"Because there are so many, our challenge is to work out what part of a molecule is important for a particular application then apply that information to designing the liquid to fit the purpose."

Atkin has completed several pioneering studies in his field, and is highly regarded for his work in atomic force microscopy (the measurement of matter in nanoscale) and neutron scattering, for which he has access to the ANSTO research reactor at Lucas Heights and the ISIS facility in the UK.

Atkin this year received a prestigious Future Fellowship from the Australian Research Council (ARC) and also leads a three-year $380,000 ARC Discovery Project investigating molecular scale engineering of solid/liquid interfaces. He heads the University's Ionic Liquids Research Group and is a principal researcher in the Centres for Organic Electronics and Advanced Particle Processing and Transport. His work is also aligned with the NIER (the Newcastle Institute for Energy Resources), a key partnership between the University, government and industry for developing sustainable energy technologies.

Atkin, who was awarded his PhD at the University of Newcastle in 2003, has received consistent ARC support since 2005 and was appointed to the University of Newcastle in 2007 on a research fellowship as part of a recruitment strategy to foster a new generation of outstanding young researchers.

"Gaining the fellowship was a huge boost for me because it allowed me to establish myself in the field and build a research team," he says.

"We are well equipped here and I think the main reason our research group has been successful and has continued to attract government support is that our projects are done well and produce good outcomes and quality papers."

Career Summary

Biography

Rob Atkin is a physical chemist, and has completed several pioneering studies in a range of areas broadly classified as surface science in ionic liquid systems. These scientific breakthroughs have allowed Atkin to make contributions to the development of nanolubricants, as well as in related ionic liquid based ‘working fluid’ applications such as the use of ionic liquids for heat transfer, as solvents for electrodeposition, as electrolytes in batteries and capacitors, and even as solvents for proteins in bioreactors.  In all these processes, it is the arrangement of the ionic liquid ions near the active surface, and the way they are adsorbed to or are repelled by it, which controls performance.  The designer properties of ionic liquids can be exploited to improve function in these systems in ways that are simply not possible using conventional liquids like water or oils.

Atkin’s research into ionic liquids began in 2005.  His investigations at that time were purely fundamental: the goal was to understand how the ions arrange in the bulk of the ionic liquid, and how this structure changed near a solid surface.  It soon became clear that the liquid structure was much stronger than had previously been suspected which, combined with their remarkable physical properties, opened up the new applied research avenues for the use of ionic liquids as working fluids.

Atkin’s career research pathway demonstrates the importance of fundamental research for Australian industries into the future; the detailed understanding derived from fundamental research allows quantum leaps in process performance which are not usually possible if trial and error approaches are employed.  Nowadays, Atkin divides his research effort equally between fundamental and applied topics.

Research Expertise
A/Prof Atkin’s PhD work made significant contributions in the area of interfacial adsorption, particularly concerning the kinetics and mechanism of ionic surfactant adsorption at the solid-aqueous solution interface. The primary instrument used for determining adsorption rates was optical reflectometry. A/Prof Atkin spent optimised this technique, greatly increasing the quality of the data obtained. As optical reflectometry yields no structural information, soft-contact atomic force microscopy was used to determine the topography of the adsorbed surfactant layer, as well as the layer thickness. A/Prof Atkin’s PhD culminated with the writing of a major review article for Advances in Colloid and Interface Science in 2003. A/Prof Atkin’s postdoctoral studies at Bristol University dealt with the preparation of polymer microcapsules for controlled release applications. A/Prof Atkin contributed to the development of a novel method that allows the thickness of the polymer shell to be accurately controlled, which allows manipulation of the release profile of the encapsulated material. Two Langmuir papers and one Macromolecules paper resulted from this work. Another method for coating particles with a polymer layer that swells and de-swells with pH variation was published in Soft Matter. As an APD at the University of Sydney A/Prof Atkin completed a comprehensive study of microemulsion phase behaviour and nanostructure of ethylammonium nitrate microemulsions. A follow up investigation examined surfactant micelle, liquid crystal and microemulsion phase behaviour and structure in propylammonium nitrate, and A/Prof Atkin initiated a study using atomic force microscopy (AFM) to show the presence of self assembled surfactant aggregates at the graphite – ionic liquid interface resulting in a publication in JACS. However, the two studies most critical for subsequent work dealt with pure ionic liquids. Firstly, A/Prof Atkin used AFM to study the interfacial structure of a variety of ionic liquids on several different solid substrates. Secondly, A/Prof Atkin used small angle neutron scattering to show that protic ionic liquids have a bulk sponge-like nanostructure; although these ionic liquids had been studied for over 100 years, bulk structure was never suspected. In a subsequent book chapter A/Prof Atkin rationalised the relationship between bulk and interfacial ionic liquid structure. These two key results set the course for future research, and formed the foundation of a Australian Research Council Discovery project “Adsorption and Structure at Ionic Liquid Interfaces”. A/Prof Atkin has developed upon these results since moving to the University of Newcastle in June 2007. His group has examined the influence of temperature and molecular structure on protic and aprotic ionic liquid interfacial structure. We have found that this interfacial structure is sufficiently strong to prevent particle aggregation in ionic liquids despite the extremely high ionic strength, and found that in some cases particles settled many times faster than predicted by the Stokes equation. The properties of poly(ethylene oxide) dissolved in protic ILs has been well characterised, as has its properties adsorbed at solid-protic ionic liquid interfaces. A/Prof Atkin developed a collaboration with Professor Frank Endres (Clausthal University, Germany) dealing with the influence of ionic liquid molecular structure on electrochemical behaviour. A/Prof Atkin completed a study of the self assembly of Pluronic polymers in bulk ionic liquids and at the silica ionic liquid interface; adsorbed self assembled aggregates were identified at the interface between an ionic liquid and a charged surface for the first time. In collaboration with Professor Mark Rutland (KTH, Sweden) A/Prof Atkin has examined the structure of the protic ionic liquid-air interface and of surfactants adsorbed at this interface, and the effect of ionic liquid interfacial structure on lubricity.

Teaching Expertise
My goal as an undergraduate teacher is to produce graduates who are innovative and creative problem solvers, with a well rounded skill set in chemistry suitable for the modern world, rather than students who are simply good at examinations and completing laboratory projects where the goal is to complete a series of steps to arrive at a predetermined ‘answer’. The cornerstone of all of my teaching is the scientific process: making careful observations, asking questions, determining methods by which these questions may be answered, making predictions about the likely outcomes, and testing the methods. Essentially, the scientific process involves thinking logically, and is accessible to all people regardless of whether or not they are ‘scientifically inclined’. Once this type of thinking has been mastered, students will that they are able to make better and more informed decisions, and predictions, about many subjects outside of science.

Administrative Expertise
Co-Chair and Organiser for the 28th Australian Colloid and Surface Science Student Conference, Riverwood Downs, February 2012: With Dr Grant Webber (University of Newcastle, Chemical Engineering), I organised this biennual event which attracted over 110 delegates. This conference represents important opportunity for students to network with other students, and academics, and present their work in a semi-formal setting. A significant percentage of student attendees at previous installments of this conference have gone on to successful academic careers domestically and internationally. Guest Editor of Physical Chemistry Chemical Physics Special Edition: I was invited, along with Prof Jairton Dupont, to be guest editor of a special edition of Physical Chemistry Chemical Physics (2011, Issue 30) on the theme of nanostructures in ionic liquids. In consultation with the journal editor Philip Earis and Prof Dupont, this involved screening papers for suitability on submission, assigning reviewers, collating reviews, assessing responses to reviews from authors, and making a final judgement whether or not to accept the paper for publication. School Officer for SEC. I am assisting SELS HOS A/Prof Hugh Dunstan in analysing SEC feedback for SELS, and addressing issues in courses that receive poor results. For any course that has an overall grade of 3.6 or less I examine all of the feedback data collected and read all of the students comments, and consult with the HOS to discus appropriate courses of action. This approach is making a difference, with average scores across in all SELS courses increasing from 3.9 in 2009 to 4.05 in 2011.

Collaborations
A/Prof Atkin has a longstanding collaboration with Prof Gregory Warr (University of Sydney), dating back to 2005 when A/Prof Atkin was an Australian Research Council Postdoctoral Fellow at Sydney. Our primary area of collaboration is protic ILs, and focuses on molecular self assembly. A/Prof Atkin and Prof Warr have published 26 joint publications in the last 6 years, and over $1M ARC project funding. A/Prof Atkin has a strong collaboration with Prof Mark Rutland (KTH, Stockholm, Sweden) in two project areas. Since 2008 Atkin and Rutland have collaborated on the structure of pure ionic liquid – air interfaces, and the properties of surfactants adsorbed at these interfaces, supported by an ARC Linkage International project (LX0776612). This project was a key aspect of the PhD projects of Deborah Wakeham (University of Newcastle) and Petru Niga (KTH). In 2010 A/Prof Atkin initiated a new project with Prof Rutland concerning ionic liquid nanotribology. Together, we have attracted 3 joint grants and published 8 joint papers. A/Prof Atkin’s collaboration with Prof Frank Endres (Clausthal University, Germany) concerning ionic liquid interfacial structure and surfaces as they relate to electrochemistry has produced nine joint publications in the last four years and 2 joint grants. Prof Endres' group performs electrodeposition, scanning tunnelling microscopy (STM) and cyclic voltammetry experiments that complement AFM studies performed at Newcastle. A/Prof Atkin has a productive collaboration with Dr Silvia Imberti, a neutron diffraction instrument scientist at ISIS, UK. To date this work (also in collaboration with Prof Warr) has focussed on protic ionic liquid nanostructure, and has produced four joint publications with another four articles in preparation. Since 2008, this group has been awarded neutron diffraction beam time at ISIS with a commercial value in excess of $500 K. A/Prof Atkin has collaborated with Dr Kislon Voitchovsky (EPFL, Lausanne, Switzerland) since 2012 on high resolution AFM images of solid ionic liquid interfaces. Together they have published 1 joint article. A/Prof Atkin, together with Dr Grant Webber (University of Newcastle) have established AFM nanotribology in IL systems as a capability with the University of Newcastle, and are jointly supervising a 2 PhD students. A/Prof Atkin and A/Prof Webber have 2 joint grants and several joint publications. A/Prof Atkin has collaborated with Dr Alister Page (University of Newcastle) on the structure of solid ionic liquid interfaces since 2013. Dr Page is performing MD simulations of the iterations of ionic liquids with surfaces that are correlated with AFM images and force curves. They are currently joint supervising 1 student.

Small angle neutron scattering has been used to probe the self-assembled structures formed by novel block copolymers in water and two protic ionic liquids (ILs), ethylammonium nitrate (EAN) and propylammonium nitrate (PAN). The block copolymers consist of solvophilic poly(ethylene oxide) (PEO) tethered to either poly(ethyl glycidyl ether) (PEGE) or poly(glycidyl propyl ether) (PGPrE) solvophobic blocks. Four block copolymers (EGE109EO54, EGE113EO115, EGE104EO178, and GPrE98EO260) have been investigated between 10 and 100 °C, showing how aggregate structure changes with increasing the EO block length, by changing the insoluble block from EGE to the more bulky, hydrophobic GPrE block, and with temperature. EO solubility mainly depends on the hydrogen bond network density, and decreases in the order H2O, EAN, and then PAN. The solubility of the EGE and GPrE blocks decreases in the order PAN, EAN then water because the large apolar domain of PAN increase the solubility of the solvophobic blocks more effectively than the smaller apolar domains in EAN, and water, which is entirely hydrophilic; GPrE is less soluble than EGE because its larger size hinders solubilization in the IL apolar domains. Large disk-shaped structures were present for EGE109EO54 in all three solvents because short EO chains favor flat structures, while GPrE98EO260 formed spherical structures because long EO chains lead to curved aggregates. The aggregate structures of EGE113EO115 and EGE104EO178, which have intermediate EO chain lengths, varied depending on the solvent and the temperature. Solubilities also explain trends in critical micelle concentrations (cmc) and temperatures (cmt).

Three Australian sub-bituminous coals were treated with three different ionic liquids (ILs) at a temperature of 100 °C. The thermal behaviour of these treated coals were compared against raw coals via pyrolysis experiments in a Thermogravimetric Analyser. Morphological comparisons were also made via Scanning Electron Microscopy. Among the studied ILs, 1-butyl-3-methylimidazolium chloride [Bmim][Cl] was found to perform the most consistently in being able to alter the thermal and morphological properties of most of the coals used. It is posited that this may be due to the large difference in charge density between the delocalised charge of the large bmim cation and the chloride anion which allows this IL to disrupt the cross linked network of coal. It was also found that the interactions of the ionic liquids are coal specific, for instance none of the ionic liquids were able to change the thermal properties of coal A. Moreover, the results indicated that among the studied coals, coal R showed the highest mass loss during pyrolysis in TGA and coal C showed the highest amount of swelling and fragmentation in SEM images. The results displayed in this study indicate that the potential for ionic liquids to be used as pre-treatments in coal liquefaction is promising. Crown

A unique, but unifying, feature of ionic liquids (ILs) is that they are nanostructured on the length scale of the ions; in many ILs well-defined polar and apolar domains exist and may percolate through the liquid. Near a surface the isotropic symmetry of the bulk structure is broken, resulting in different nanostructures which, until now, have only been studied indirectly. In this paper, in situ amplitude modulated atomic force microscopy (AM-AFM) has been used to resolve the 3-dimensional nanostructure of five protic ILs at and near the surface of mica. The surface and near surface structures are distinct and remarkably well-defined, but are very different from previously accepted descriptions. Interfacial nanostructure is strongly influenced by the registry between cations and the mica surface charge sites, whereas near surface nanostructure is sensitive to both cation and anion structure. Together these ILs reveal how interfacial nanostructure can be tuned through ion structure, informing "bottom-up" design and optimisation of ILs for diverse technologies including heterogeneous catalysis, lubrication, electrochemical processes, and nanofluids.

Atomic force microscope (AFM) force curves and images are used to characterize the adsorbed layer structure formed by a series of diblock copolymers with solvophilic poly(ethylene oxide) (PEO) and solvophobic poly(ethyl glycidyl ether) (PEGE) blocks at silica-water and silica-ethylammoniun nitrate (EAN, a room temperature ionic liquid (IL)) interfaces. The diblock polyethers examined are EGE109EO54, EGE113EO115, and EGE104EO178. These experiments reveal how adsorbed layer structure varies as the length of the EO block varies while the EGE block length is kept approximately constant; water is a better solvent for PEO than EAN, so higher curvature structures are found at the interface of silica with water than with EAN. At silica-water interfaces, EGE109EO54 forms a bilayer and EGE113EO115 forms elongated aggregates, while a well-ordered array of spheres is present for EGE104EO178. EGE109EO54 does not adsorb at the silica-EAN interface because the EO chain is too short to compete with the ethylammonium cation for surface adsorption sites. However, EGE113EO115 and EGE104EO178 do adsorb and form a bilayer and elongated aggregates, respectively.

Surface nanobubbles produced by supersaturation during the exchange of ethanol for water are routinely observed on hydrophobic surfaces, are stable for days, and have contact angles that are very much greater than observed macroscopically. Here, we test the hypothesis that nanobubbles can also be observed in nonaqueous solvents in order to ascertain if their anomalous lifetimes and contact angles are related to properties of the solvent. Nanobubbles were seen in the protic solvents formamide, ethylammonium nitrate, and propylammonium nitrate, but not in propylene carbonate or dimethyl sulfoxide. Solvents in which nanobubbles were observed exhibit a three-dimensional hydrogen-bonding network. Like in aqueous systems, the nanobubbles were stable for days and exhibited high contact angles (~165°).

Ionic liquids (ILs) are attractive solvents for devices such as lithium ion batteries and capacitors, but their uptake is limited, partially because their Stern layer nanostructure is poorly understood compared to molecular solvents. Here, in situ amplitude-modulated atomic force microscopy has been used to reveal the Stern layer nanostructure of the 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide (EMIm TFSI)-HOPG (highly ordered pyrolytic graphite) interface with molecular resolution. The effect of applied surface potential and added 0.1 wt/wt % Li TFSI or EMIm Cl on ion arrangements is probed between ±1 V. For pure EMIm TFSI at open-circuit potential, well-defined rows are present on the surface formed by an anion-cation-cation-anion (A-C-C-A) unit cell adsorbed with like ions adjacent. As the surface potential is changed, the relative concentrations of cations and anions in the Stern layer respond, and markedly different lateral ion arrangements ensue. The changes in Stern layer structure at positive and negative potentials are not symmetrical due to the different surface affinities and packing constraints of cations and anions. For potentials outside ±0.4 V, images are featureless because the compositional variation within the layer is too small for the AFM tip to detect. This suggests that the Stern layer is highly enriched in either cations or anions (depending on the potential) oriented upright to the surface plane. When Li+ or Cl- is present, some Stern layer ionic liquid cations or anions (respectively) are displaced, producing starkly different structures. The Stern layer structures elucidated here significantly enhance our understanding of the ionic liquid electrical double layer.

In this paper, we present results on the nanoscale interactions of LiTFSI-[Py1, 4]TFSI with Au(111) using cyclic voltammetry and atomic force microscopy (AFM). Raman spectroscopy was used to understand the Li+ ion coordination with the TFSI- ion and showed that with increase in LiTFSI concentration in [Py1, 4]TFSI, the Li+ ion solvation structure significantly changes. Correspondingly, the force-distance profile in AFM revealed that at lower concentrations of LiTFSI (0.1 M) a multilayered structure is obtained. On increasing the concentration of LiTFSI (0.5 and 1 M), a significant decrease in the number of interfacial layers was observed. With change in the potential, the interfacial layers were found to vary with an increase in the force required to rupture the layers. The present study clearly shows that Li+ ions vary the ionic liquid/Au(111) interface and could provide insight into the interfacial processes in ionic liquid based lithium batteries.

The remarkable physical properties of ionic liquids (ILs) make them potentially excellent lubricants. One of the challenges for using ILs as lubricants is their high cost. In this article, atomic force microscopy (AFM) nanotribology measurements reveal that a 1 mol % solution of IL dissolved in an oil lubricates the silica surface as effectively as the pure IL. The adsorption isotherm shows that the IL surface excess need only be approximately half of the saturation value to prevent surface contact and effectively lubricate the sliding surfaces. Using ILs in this way makes them viable for large-scale applications.

Atomic force microscopy (AFM) force measurements elucidate the effect of cation alkyl chain length and the anion species on ionic liquid (IL) interfacial structure at highly ordered pyrolytic graphite (HOPG) surfaces as a function of potential. Three ILs are examined: 1-hexyl-3-methylimidazolium tris(pentafluoroethyl)trifluorophosphate ([HMIM] FAP), 1-ethyl-3-methylimidazolium tris(pentafluoroethyl)trifluorophosphate ([EMIM] FAP), and 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([EMIM] TFSA). The step-wise force-distance profiles indicate the ILs adopt a multilayered morphology near the surface. When the surface is biased positively or negatively versus Pt quasireference electrode, both the number of steps, and the force required to rupture each step increase, indicating stronger interfacial structure. At all potentials, push-through forces for [HMIM] FAP are the highest, because the long alkyl chain results in strong cohesive interactions between cations, leading to well-formed layers that resist the AFM tip. The most layers are observed for [EMIM] FAP, because the C2 chains are relatively rigid and the dimensions of the cation and anion are similar, facilitating neat packing. [EMIM] TFSA has the smallest push-through forces and fewest layers, and thus the weakest interfacial structure. Surface-tip attractive forces are measured for all ILs. At the same potential, the attractions are the strongest for [EMIM] TFSA and the weakest for [HMIM] FAP because the interfacial layers are better formed for the longer alkyl chain cation. This means interfacial forces are stronger, which masks the weak attractive forces.

The interactions between vitrinite and inertinite-rich coals and the ionic liquid butylimidazolium chloride ([bmim][Cl]) heated to 100 C have been characterised. Differences in the interactions of coal macerals and ionic liquids have been identified. [bmim][Cl] is able to dissolve 22 wt% of a high-vitrinite coal fraction compared to 14 wt% of a high-inertinite coal fraction. The vitrinite-rich coal fraction tends to swell to a greater extent compared to the inertinite-rich coal fraction, which was fractured and fragmented rather than swelled. © 2013 Published by Elsevier Ltd.

Steady shear viscosity measurements have been performed on 100. kDa poly(ethylene oxide) (PEO) dissolved in the protic ionic liquids ethylammonium nitrate (EAN) and propylammonium nitrate (PAN) and in water. The zero shear viscosity in all three solvents increases with polymer concentration, falling into three concentration regimes corresponding to dilute, semi-dilute and network solutions. Huggins plots reveal three distinct solvent conditions: good (water), good-theta (EAN) and theta (PAN). However, differences in the transition concentrations, power law behaviour of the viscosities, and relaxation times arising from shear thinning in the two ILs can be directly related to the effects of solvent nanostructure. © 2014 Elsevier Inc.

Ionic liquids (IL) exhibit a remarkably diverse interfacial chemistry, with multiple interfacial layers present at the IL/solid interface. Ionic liquids (ILs) are pure salts with melting points typically less than 100°C. It has remarkable physical properties, which include wide electrochemical stability windows, high ionic conductivity and negligible vapor pressure. The adsorption strength of ILs onto solid surfaces is much higher than for typical organic solvents or water. The structure and composition of the interfacial layer can be tuned by varying the surface potential and the ionic structure, and by addition of solutes. This allows us to envision that IL interfacial properties can be readily matched to a particular application once the required fundamental understanding is elucidated. STM and AFM results show that the IL cation has a strong influence on the structure and composition of the interface.

The nanostructure of a 50:50 vol% mixture of glycerol and ethylammonium formate (EAF), a protic ionic liquid (IL), has been investigated using neutron diffraction and empirical potential structure refinement (EPSR) fits. EPSR fits reveal that the mixture is nanostructured. Electrostatic interactions between IL charge groups leads to the formation of ionic regions. These solvophobically repel cation alkyl groups which cluster together to form apolar domains. The polar glycerol molecules are preferentially incorporated into the charged domains, and form hydrogen bonds with EAF groups rather than with other glycerol molecules. However, radial distribution functions reveal that glycerol molecules pack around each other in a fashion similar to that found in pure glycerol. This suggests that a glycerol channel runs through the ionic domain of EAF. The absence of significant glycerol-glycerol hydrogen bonding indicates that glycerol molecules are able to span the polar domain, bridging EAF charge groups. Glycerol can adopt six distinct conformations. The distribution of conformers in the EAF mixture is very different to that found in the pure liquid because hydrogen bonds form with EAF rather than with other glycerol molecules, which imparts different packing constraints. © 2014 The Owner Societies.

The thermal conductivities of nine protic ionic liquids (ILs) have been investigated between 293 and 340 K. Within this range, the thermal conductivities are between 0.18 and 0.30 W·m-1·K-1. These values are higher than those typically associated with oils and aprotic ILs, but lower than those of strongly hydrogen bonding solvents like water. Weak linear decreases in thermal conductivity with temperature are noted, with the exception of ethanolammonium nitrate (EtAN) where the thermal conductivity increases with temperature. The dependence of thermal conductivity on IL type is analyzed with use of the Bahe-Varela pseudolattice theory. This theory treats the bulk IL as an array of ordered domains with intervening domains of uncorrelated structure which enable and provide barriers to heat propagation (respectively) via allowed vibrational modes. For the protic ILs investigated, thermal conductivity depends strongly on the IL cation alkyl chain length. This is because the cation alkyl chain controls the dimensions of the IL bulk nanostructure, which consists of charged (ordered domains) and uncharged regions (disordered domains). As the cation alkyl chain controls the dimensions of the disordered domains, it thus limits the thermal conductivity. To test the generality of this interpretation, the thermal conductivities of propylammonium nitrate (PAN) and PAN-octanol mixtures were examined; water selectively swells the PAN charged domain, while octanol swells the uncharged regions. Up to a certain concentration, adding water increases thermal conduction and octanol decreases it, as expected. However, at high solute concentrations the IL nanostructure is broken. When additional solvent is added above this concentration the rate of change in thermal conductivity is greatly reduced. This is because, in the absence of nanostructure, the added solvent only serves to dilute the salt solution.

Density functional tight binding (DFTB), which is ~100-1000 times faster than full density functional theory (DFT), has been used to simulate the structure and properties of protic ionic liquid (IL) ions, clusters of ions and the bulk liquid. Proton affinities for a wide range of IL cations and anions determined using DFTB generally reproduce G3B3 values to within 5-10 kcal/mol. The structures and thermodynamic stabilities of n-alkyl ammonium nitrate clusters (up to 450 quantum chemical atoms) predicted with DFTB are in excellent agreement with those determined using DFT. The IL bulk structure simulated using DFTB with periodic boundary conditions is in excellent agreement with published neutron diffraction data.

The highly ordered pyrolytic graphite (HOPG)/1-octyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([OMIm]Tf2N) interface is examined by ultrahigh vacuum scanning tunneling microscopy (UHV-STM), atomic force microscopy (UHV-AFM) (and as a function of potential by in situ scanning tunneling microscopy (STM)), in situ atomic force microscopy (AFM), and density functional theory (DFT) calculations. In situ STM and AFM results reveal that multiple ionic liquid (IL) layers are present at the HOPG/electrode interface at all potentials. At open-circuit potential (OCP), attractions between the cation alkyl chain and the HOPG surface result in the ion layer bound to the surface being cation rich. As the potential is varied, the relative concentrations of cations and anions in the surface layer change: as the potential is made more positive, anions are preferentially adsorbed at the surface, while at negative potentials the surface layer is cation rich. At -2 V an unusual overstructure forms. STM images and AFM friction force microscopy measurements both confirm that the roughness of this overstructure increases with time. DFT calculations reveal that [OMIm]+ is attracted to the graphite surface at OCP; however, adsorption is enhanced at negative potentials due to favorable electrostatic interactions, and at -2 V the surface layer is cation rich and strongly bound. The energetically most favorable orientation within this layer is with the [OMIm]+ octyl chains aligned "epitaxially" along the graphitic lattice. This induces quasi-crystallization of cations on the graphite surface and formation of the overstructure. An alternative explanation may be that, because of the bulkiness of the cation sitting along the surface, a single layer of cations is unable to quench the surface potential, so a second layer forms. The most energetically favorable way to do this might be in a quasi-crystalline/multilayered fashion. It could also be a combination of strong surface binding/orientations and the need for multilayers to quench the charge. © 2014 American Chemical Society.

In this overview paper we present a combined in situ STM, AFM and EIS study on the structure and dynamics of the interfacial layers between Au(111) and two extremely pure ionic liquids, namely [Py1,4]FAP and [EMIM]FAP. The combination of these methods provides valuable information for both neutral and electrified interfaces. In situ STM and AFM results reveal that a multilayered ion morphology is present at the IL-Au(111) interface, with stronger near surface layering detected at higher electrode potentials. The in situ STM measurements show that the structure of the interfacial layers is dependent on the applied electrode potential, the number of subsequent STM scans and the scan rate. Furthermore, in the case of [Py1,4]FAP, the Au(111) surface undergoes herringbone reconstruction, Au(111)(22×3), in the cathodic potential regime, and the ultra-slow formation of vacancies in the herringbone structure is probed with in situ STM. EIS measurements reveal the presence of two distinct capacitive processes at the interface taking place on different time scales. The time scale of the fast process is typically in the millisecond range and is governed by the bulk ion transport in the IL, which exhibits a Vogel-Fulcher-Tammann-type temperature dependence. The slow process takes place on a time scale of seconds and is Arrhenius activated. The contribution of this process to the overall interfacial capacitance is particularly large in the potential regime where the herringbone structure is probed. Furthermore, we analyze the temperature dependence of the interfacial capacitance. © 2013 Elsevier B.V. All rights reserved.

Silica particle suspensions of 10 wt % have been investigated in the protic ionic liquids (ILs) ethylammonium nitrate (EAN), ethanolammonium nitrate (EtAN), propylammonium nitrate (PAN), and dimethylethylammonium formate (DMEAF). Static and dynamic light scattering reveal that single particles coexist in dynamic equilibrium with flocculated networks at room temperature. These types of systems are classified as weakly flocculated and are quite rare. As weakly flocculated systems generally exist only within a narrow range of conditions, the effect of temperature was probed. When temperature is increased, the thermal motion of suspended particles increases, favoring dispersion, but in ILs suspensions, heating reduces the stabilizing effect of the interfacial structure of the IL. When subjected to a small increase in temperature, particle suspensions in ILs become unstable, indicated by the absence of a peak corresponding to single particles in the light scattering data. For EAN and DMEAF, further increasing temperatures above 40 C returns the systems to a weakly flocculated state in which thermal energy is sufficient to break particles away from aggregates. Weakly flocculated suspensions in EAN and EtAN settle more rapidly than predicted by the Stokes equation, as the particles spend a significant portion of time in large, rapidly settling flocs. Surprisingly, suspensions in PAN and DMEAF settle slower than predicted. Oscillatory rheology indicates that these suspensions are viscoelastic, due to a persistent, long-range structure in the suspension that slows settling. In aggregated systems, settling is very rapid. © 2014 American Chemical Society.

The partitioning constants and Gibbs free energies of transfer of poly(oxyethylene) n-alkyl ethers between dodecane and the protic ionic liquids (ILs) ethylammonium nitrate (EAN) and propylammonium nitrate (PAN) are determined. EAN and PAN have a sponge-like nanostructure that consists of interpenetrating charged and apolar domains. This study reveals that the ILs solvate the hydrophobic and hydrophilic parts of the amphiphiles differently. The ethoxy groups are dissolved in the polar region of both ILs by means of hydrogen bonds. The environment is remarkably water-like and, as in water, the solubility of the ethoxy groups in EAN decreases on warming, which underscores the critical role of the IL hydrogen-bond network for solubility. In contrast, amphiphile alkyl chains are not preferentially solvated by the charged or uncharged regions of the ILs. Rather, they experience an average IL composition and, as a result, partitioning from dodecane into the IL increases as the cation alkyl chain is lengthened from ethyl to propyl, because the IL apolar volume fraction increases. Together, these results show that surfactant dissolution in ILs is related to structural compatibility between the head or tail group and the IL nanostructure. Thus, these partitioning studies reveal parameters for the effective molecular design of surfactants in ILs. Surfactants in ionic liquids: The dissolution and solvation of the hydrophilic and hydrophobic components of non-ionic surfactants in ionic liquids are affected by solvent nanostructure and hydrogen bonding. The polar domains of protic ionic liquids ethyl- and propylammonium nitrate are, thermodynamically speaking, remarkably water-like. © 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

The interfacial ordering of Ionic liquids leads to interesting nanotribological properties as revealed by colloid probe studies. The first of these is the clear correlation between the number of ion pairs trapped in the tribological contact and the friction coefficient displayed. The second is the fact that the surface electrical potential can be used to control the composition of the boundary layer and thus tune the friction. Thirdly, the interfacial ordering appears to significantly affect the fluid dynamics over large distances.

The lubricating properties of ionic liquids can be controlled by varying the molecular structure of the ions1'2 and by applying an electric potential to the sliding contact.3 Results for two systems will be presented. Firstly, the lubricating properties of protic ionic liquids confined between silica and mica surfaces will be examined. Atomic force microscope (AFM) images combined with normal and lateral force curves allows variation in lubricity as a function of normal load to be correlated with differences in the lateral structure of the ions confined between the surfaces. Secondly, results for aprotic ionic liquids confined between silica and gold surfaces will be presented. Friction forces vary with the potential applied to the gold surface because the composition of the ion layer confined between the two surfaces changes from cation-enriched (at negative potentials) to anion-enriched (at positive potentials); whether lubricity is increased or decreased as the composition changes depends on the ion species (c.f. Figure below). This offers a new approach to tuning factional forces reversibly at the molecular level without changing the substrates by employing a self-replenishing boundary lubricant of low vapour pressure.
