The contents will interest a wide range of researchers in many fields of chemistry.

In this compilation, the authors begin by highlighting the recent developments in asymmetric 1,4- and 1,2- additions to α, β-unsaturated carbonyl compounds. The recent finding of Cu (I)-catalyzed asymmetric 1,2-addition of Grignard reagents to α, β-unsaturated carbonyl compounds, as well as aromatic ketones, has categorically revolutionized catalytic asymmetric reactions.This compilation also aims to use the well-known coordination preference of zinc in phthalocyanine and porphyrin ligands in correlation with supramolecular systems. The light-absorption process in dye-sensitized solar cells is studied using the time-dependent density functional theory.In recent years, a series of investigations on detonation wave formation in acetylene have been published. In these studies, it was shown that the formation of detonation proceeds entirely due to the energy released during the condensation of carbon nanoparticles during the growth of poly-aromatic hydrocarbons. The results of these studies are summarized and practical applications are discussed.The authors discuss aromatic amines, derivatives of aromatic hydrocarbons containing an amino group/an amine group/nitrogen atom in their structures. These compounds represent one of the most important classes of industrial and environmental chemicals. Three groups have been studied: monocyclic, polycyclic, and heterocyclic aromatic amines, which are used as intermediates in azo dye manufacturing, pigments, drugs, antibiotics, antidepressants, pesticides, and other industrial products.In the closing study, the GC-MS/MS method has been developed for the determination and quantification of 35 multiclass pesticide residues in chili samples. Pesticides were selected from different families including organochlorines, organophosphorus, carbamates, pyrethroids, triazines, triazoles, and pyrazoles. The QuEChERS-dSPE method was used for the extraction of pesticide residue.

This edited volume comprises five chapters, each detailing recent updates in chemistry research. Chapter One describes different types of polymer electrolytes and their preparation methods as well as ion transport mechanisms, methods of improving properties, and techniques for evaluating their structure and properties. Chapter Two analyzes the scopes and limitations of chromatography, NMR spectroscopy, and UV spectroscopy for assigning fullerene C60 regioisomeric multiadducts. Chapter Three focuses on electrochemical techniques used for developing insulin sensors of high specificity and sensitivity. Chapter Four presents selected contemporary achievements of different computational methods in modeling of natural and newly synthesized compounds with determined antibacterial, antifungal and antiviral activities. Lastly, Chapter Five reviews some metal porphyrins of manganese, cobalt, vanadium, and chromium and their catalytic applications.

Advances in Chemistry Research. 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.
