This reprint reports advances in the topic of Deep Eutectic Solvents regarding their use as green alternatives in different chemical applications. Studies on the extraction/preconcentration processes of pharmacologically relevant molecules, structural spectroscopic studies, and application in gas purification studies are reported. Two relevant reviews are also published in the context of carbon dioxide conversion and their use in the chemistry of transformations. This reprint therefore aims to summarize some of the pertinent issues in DES chemistry through relevant literature references.

Comprising 12 chapters, this book focuses on volatile methylsiloxanes (VMSs), the shorter-chained organosiloxanes, and reviews the main areas and environmental compartments where they have been found and studied. It opens with a detailed description of the structural and functional properties, toxic risks and possible transformations of VMSs in the environment and their main uses in various activities and products, as well as the identification of the main sources of emission. Further chapters examine the analytical strategies and protocols that have been used to address the quantification of VMSs, including the issue of possible cross-contaminations. The book also discusses the presence of VMSs in wastewater treatment plants (WWTPs) and in water bodies, their atmospheric fate and levels in biota, as well as occurrences of VMSs in remote areas of the world. It closes with a comprehensive conclusion and discussion on future directions for upcoming studies. This book is not intended as a finishing line, but rather as an important step towards improving our understanding of VMSs, to fuel new collaborations between research groups and/or with industry and lastly to convince more researchers to explore the mysteries of these ubiquitous, yet understudied, chemicals.

The chemistry of silicon has always been a field of major concern due to its proximity to carbon on the periodic table. From the molecular chemist's viewpoint, one of the most interesting differences between carbon and silicon is their divergent coordination behavior. In fact, silicon is prone to form hyper-coordinate organosilicon complexes, and, as conveyed by reports in the literature, highly sophisticated ligand systems are required to furnish low-coordinate organosilicon complexes. Tremendous progress in experimental, as well as computational, techniques has granted synthetic access to a broad range of coordination numbers for silicon, and the scientific endeavor, which was ongoing for decades, was rewarded with landmark discoveries in the field of organosilicon chemistry. Molecular congeners of silicon(0), as well as silicon oxides, were unveiled, and the prominent group 14 metalloid proved its applicability in homogenous catalysis as a supportive ligand or even as a center of catalytic activity. This book focuses on the most recent advances in the coordination chemistry of silicon with transition metals as well as main group elements, including the stabilization of low-valent silicon species through the coordination of electron donor ligands. Therefore, this book is associated with the development of novel synthetic methodologies, structural elucidations, bonding analysis, and also possible applications in catalysis or chemical transformations using related organosilicon compounds.
