The isopropylation of naphthalene (NP) was carried out over a BEA zeolite (BEA38; SiO2/Al2O3 = 38) focused on the selectivities for diisopropylnaphthalene (DIPN) and triisopropylnaphthalene (TriIPN) isomers. The isopropylation gave possible eight DIPN isomers including ß,ß- (2,6- and 2,7-), a,ß- (1,3-, 1,6-, and 1,7-), and a,a- (1,4- and 1,5-). The catalysis over BEA works two types of controls: kinetic control operates to form predominantly bulky and unstable a,a-DIPN at low temperatures, and thermodynamic controls work for the predominant formation of the slim and stable ß,ß-DIPN at high temperatures, although the intermediately bulky and stable a,ß-DIPN are the major products through both controls. The enhanced selectivities for ß,ß-DIPN were observed at the early stages of the catalysis in the range of 200-300 °C, which operate under new type of thermodynamic control over fresh catalyst through thermodynamically preferred transition states; however, they decreased with the increase in the selectivities for a,a- and a,ß-DIPN, and converged after prolonged reaction period. The isopropylation of DIPN isomers gives TriIPN isomers: unstable and bulky 1,3,5- and 1,4,6-TriIPN with a,a,ß-substitution, and stable and slim 1,3,7- and 1,3,6-TriIPN with a,ß,ß-substitution. The low temperatures favor the former isomers, whereas the selectivity for the latter isomers increases with increasing reaction temperature. These results indicate that TriIPN isomers principally form under kinetic control at low temperatures, and thermodynamic controls participate in the catalysis at high temperatures. The selectivities for TriIPN isomers kept constant during the reaction at all temperatures: 200, 250, and 300 °C. The catalysis occurs inside the BEA channels and allow even the formation of bulky 1,3,5- and 1,4,6-TriIPN; however, all isomers cannot be isomerized to the others in the channels and on the external surfaces. Severe coke-deposition occurred during the catalysis, particularly in the early stages; however, the catalyst is recovered by the calcination with a small change in catalytic activity.

Skin cancer has emerged as one of the leading types of cancers in the world, causing a high impact on the global burden of health and the economy. Basal cell and squamous cell carcinoma are the localized forms of skin cancer with a high prevalence and can be treated with a high success rate. However, melanoma, a rare type of skin cancer with a high mortality rate, can metastasize and invade other parts of the body. Various skin cancer treatment approaches have been developed and advanced from localized to systemic treatment over the years to improve the low success rate associated with skin cancer, especially metastatic melanoma. The systemic treatment of skin cancer is highly benefitted by drug delivery systems (DDS) designed to function with much higher specificity and lower side effects than the direct treatment with drugs. While many nanomaterials based DDS have been developed in the past few years to take advantage of the small size and high functionality of nanomaterials, silica-based nanomaterials have recently emerged as the flexible DDS with a high biocompatibility, good clearance, a high drug loading capacity, and versatility to attach several drugs and targeting agents to its surface. In this review, recent progress in the treatment of melanoma using silica-based nanomaterials and their hybrids is discussed, highlighting the versatility and potential of these emerging nanomaterials as the DDS for delivering various molecules, including drugs and immunotherapy agents, peptides, and radio- and photo-active agents. The review also introduces various therapies available for the treatment of melanoma, including surgery, chemotherapy, targeted therapy, phototherapy, and immunotherapy and discusses the improvement in these therapies based on silica-based DDS. The review also highlights the role of silica nanomaterials and their hybrids in delivering combination therapy and the advantages of silica nanohybrids over pure silica-based DDS. Finally, we summarize the present status of silica-based nanomaterials in melanoma treatment and the current challenges that have to be solved for the clinical translation of these materials as DDS.

In this investigation, a hybrid of metal sulfide and carbon nitride (CN) is synthesized by in-situ chemical conversion between metallic species and a single precursor of carbon, nitrogen and sulfur elements through a strong p-d conjugation approach. It is observed that the local chemical alteration in the vicinity of N atom in the CN template triggers the formation of a highly p-conjugated CN system and efficient p-d hybridization at heterointerface. This is accelerated by partial substitution of the Fe atom for Mn ions in the MnS phase which significantly enhances the battery performance, delivering 2031 mA h g-1 after 500 cycles with inverse capacity growth. Via systematic in-depth characterizations, it is found that the gradual increase of Li-ion diffusion coefficients and charge transfer kinetics for repeated cycling is ascribed to the highly dispersed and uniform particles that are confined within the CN template through a strong p-d hybridization.

An integrated photocatalyst was prepared and its photoelectrocatalytic behavior for solar energy conversion was investigated. To make an integrated photocatalyst for hydrogen evolution, Pt and CdS clusters were embedded in zeolite as a cocatalyst and a photocatalyst, respectively. Pt particles were embedded in zeolite Y by ion exchange reaction with Pt (NH3)42+ and activation and reduction processes were followed. CdS clusters in zeolite Y cages were prepared by ion exchange reaction with Cd2+ and sulfurization with Na2S in aqueous solution was followed. The existence of CdS clusters in the cavities of zeolite Y was detected by IR spectra. UV absorption edges of the samples prepared show blue shifts about 0.03-0.12 eV from the edge of bulk CdS, which is an indication of CdS clusters formed in zeolite Y. The pore structure of samples was analyzed by BET and Langmuir method. The solar energy conversion into hydrogen was investigated, where sodium tartrate solution was used as a hole scavenger. We could observe that 1 wt% Pt supported sample was the most effective photocatalyst for hydrogen evolution (62 µL/mg after 4 hour reaction).

Toluene is an aromatic pollutant that can be widely found in many industries. Due to its toxicity, its total decomposition has been investigated by many researchers using various ways. One alternative way is the usage of catalyst and light to decompose toluene. However, so far, it is still remained as a challenge. On the other hand, the need to use cheap, abundant, and safe sources to prevent our sustainability makes the utilization of solar energy one of the ideal solutions for our problems. As visible light is the main part of our solar energy, the development of photocatalysts that able to work under visible light irradiation is highly required. One of the efforts to realize it is by designing materials that able to absorb visible light especially that of longer wavelength, such as up to 600 nm. A red color-material, Tantalum (V) nitride (Ta3N5) is one such potential photocatalyst. Its photocatalytic activity was discovered for water splitting reaction under visible light irradiation [1]. Recent progress reported that Ta 3N5 nanoparticles showed higher activity than the bulk Ta3N5 for hydrogen evolution [2] and methylene blue degradation [3]. ©2010 IEEE.
