Volume 63 considers the recent achievements in the field of biomimetic sol-gel mineralization of natural polysaccharides for obtaining biologically active silicon-containing hydrogel materials, as well as the effect of the chirality of the main classes of biomimetics on their functional properties. The effects of reaction conditions such as temperature, weight hour space velocity and catalyst modification using different types of metals on catalyst activity and selectivity are explored. Following this, a review is provided on the influence of different acid types on the reaction course and selectivity of Prins cyclization of chosen aldehydes and homoallylic alcohols. In addition, an investigation of the best methanol to olefin conversion catalyst, SAPO-34, is studied in both synthesis and metal promotion. The penultimate chapter highlights the properties of Casuarina fruit as adsorbent material for water pollutants removal. These findings are expected to shed some light on the removal performance, as well as promising applications of Casuarina fruit-based activated carbon for wastewater treatment. Lastly, nanoparticles of phthalic acid/aluminum nitrate are synthesized using a hydrothermal method, leading to a large quantity of CAU-10-H.

Volume 62 first provides information related to the synthesis, morphology, crystal structure, and porosity of bentonite and bentonite/magnetite powders. Following this, the authors discuss carbon tetrachloride, a clear, colourless, volatile and very stable chlorinated hydrocarbon with a non-polar nature, making it an excellent solvent. Recent research on the applications of hydrogen peroxide as oxidizing and reducing agent is presented, as well as its application in biocatalysis, as signaling molecule, and in nanochemistry. The mode of action hydrogen peroxide induces in yeast apoptosis is also addressed, including overexpression of apoptosis inducing factor homologue proteins. Additionally, this compilation describes the recent advances concerning the use of hydrogen peroxide in heteropolyacid-catalyzed oxidation reactions of terpenic alcohols, which are renewable origin compounds whose oxidation provides aldehydes and epoxides. Diamines, organic compounds with two amino groups, are described. In one study, different diamines are synthesized with complex formulas used in the preparation of different thermally stable polymers. A few diamines used in developing thin-film polyamide composite membranes are reviewed. The concluding study is focused on gas hydrates, mixtures of light gases such as methane, ethane or carbon dioxide, and water molecules under a special temperature and pressure condition, forming a liquid-like material.

Volume 60 opens with a chapter on Massbauer spectroscopy, a spectroscopic method based on the Massbauer effect, which can be defined as the nearly recoil-free, resonant absorption and emission of g-rays in solids. Next, the authors the chemical structure of various alkene oligomers, kinetic features of the oligomerization reactions, and applications of oligomer studies for the elucidation of the general mechanism of alkene polymerization reactions. The recent literature concerning self-assembled monolayers containing terminal glycans is reviewed, with a focus on their biomolecular interactions. Following this, the results of a study are presented wherein a reliable xanthine chemical sensor was fabricated with facile wet-chemically prepared ZnO/Al2O3/Cr2O3 nanoparticles in alkaline medium at low temperature. Various piperidine derivatives are reviewed in the context of their applications as antioxidants and anticancer agents. Today, many compounds containing piperidine are used in the treatment of various diseases. The authors also explore green methodology for the synthesis of highly functionalized piperidine under mild reaction conditions with good yields, high diastereoselectivity, operational simplicity and easy work-up procedures. In closing, an outline of applications of the applications of various piperidine derivatives as antipsychotic agents is provided. Antipsychotic drugs have a wide range of pharmacological effects such as promoting sleep.

This compilation opens with a study on the catalytic conversion of methanol to olefins, mainly SAPO-34 and ZSM-5, as well as the synthesis, properties, applications. A description of phenylalanine ammonia-lyase is presented in relation to structure, localization, expression, regulation, assay methods and the factors influencing phenylalanine ammonia-lyase activity, as well as its importance to the phenylpropanoid pathway for plant growth and development. The authors critically analyze the development of molecular nanocatalysts based on organochalcogenligands and their applications in the transfer of hydrogenation. Following this, the progress in applications of dimensional analysis and similarity theory in electrochemical kinetics and electrochemical engineering is discussed. The use of dimensionless groups in problems of current density distribution and electrochemical mass transfer is described and the similarity criteria involved are considered. The authors focus on various solvent-minimized sample pre-treatment procedures which are inexpensive and offer minimal exposure to toxic organic solvents during sample analysis. The concluding chapter explores bis-azides, i.e., organic compounds presenting two azido groups in their structures. Their utility in synthetic group transformation is covered, as well as in polymer chemistry, the preparation of bioactive compounds, click chemistry, and in the synthesis of cross-linked DNA.

The opening chapter reviews the many theoretical predictions of nitrogen oligomers and discusses their potential applications. Predictions of nitrogen oligomers encapsulated in carbon nanotubes, free standing oligomers and single crystals of nitrogen oligomers are also discussed. Additionally, a focus on the synthesis of various electron push and electron pull units towards the construction of push-pull unit decorated oligomers and their application as organic optoelectronic materials is presented. The authors provide a summary of relevant methodologies for using an alcohol as reducing agent. The authors go on to examine how yellow laccases differ from blue laccases in fungal strains. Laccase is an oxidoreductase with four copper ions in two active sites, which catalyses the oxidation of reduced substrates usually phenols or aromatic amines, coupled with the reduction of molecular oxygen to water. The penultimate chapter discusses the novel features of biphenyl based systems and how their rigidity and compactness provide detectable signals even for poorly conducting conformations. A literature review on ethylbenzene extraction using ionic liquids is presented in the final section and the results are discussed in the light of selectivity and distribution coefficients since both of them affect process efficiency.
