Available in PDF, EPUB and Kindle. Book excerpt: Chemistry was at one time completely described in terms of collision theo ry, in which one molecule collided with another, sometimes producing reac tion. Then came the realization that enzymes which are highly efficient ca talysts, work by way of prior complexation, often stereospecific, which is then followed by chemical reaction. Thus, systems that exhibit "host-guest" relationships, i.e., that show complexing are being looked at an ever in creasing frequency. The cyclodextrins are the first and probably the most important example of compounds that exhibits complex formation. This is a book about the cyclodextrins. There are of course other compounds that exhibit "host-guest" relationships and thus bind other organic molecules, but so far they have not achieved the importance of the cyclodextrins. By their name it is obvious that cyclodextrins are cyclic compounds. The complexes that they form are therefore cyclic inclusion complexes. Because the complexes are cyclic in nature, complexation can be very strong, as op posed to 1t-complex, electrostatic, or apolar complexes in which complex formation is two-dimensional rather than three-dimensional. Cyclodextrins turn out to be excellent models of enzymes. This is proba bly not fortuitous because they were first sought since it was discovered that the principal binding in the enzyme chymotrypsin was a cyclic inclusion complex. Cyclodextrins can do more than form cyclic inclusion complexes, they can catalyze as well. But catalysis always occurs after complex formation.

Available in PDF, EPUB and Kindle. Book excerpt: This book commemorates the 25th anniversary of the International Izatt-Christensen Award in Macrocyclic and Supramolecular Chemistry. The award, one of the most prestigious of small awards in chemistry, recognizes excellence in the developing field of macrocyclic and supramolecular chemistry Macrocyclic and Supramolecular Chemistry: How Izatt-Christensen Award Winners Shaped the Field features chapters written by the award recipients who provide unique perspectives on the spectacular growth in these expanding and vibrant fields of chemistry over the past half century, and on the role of these awardees in shaping this growth. During this time there has been an upsurge of interest in the design, synthesis and characterization of increasingly more complex macrocyclic ligands and in the application of this knowledge to understanding molecular recognition processes in host-guest chemistry in ways that were scarcely envisioned decades earlier. In October 2016, Professor Jean-Pierre Sauvage and Sir J. Fraser Stoddart (author for chapter 22 "Contractile and Extensile Molecular Systems: Towards Molecular Muscles" by Jean -Pierre Sauvage, Vincent Duplan, and Frédéric Niess and 20 "Serendipity" by Paul R. McGonigal and J. Fraser Stoddart respectively) were awarded the Nobel Prize in Chemistry alongside fellow Wiley author Bernard Feringa, for the design and synthesis of molecular machines.
Download or read book Environmental Chemistry for a Sustainable World written by Eric Lichtfouse and published by Springer Science & Business Media. This book was released on 2011-11-27 with total page 423 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental chemistry is a fast developing science aimed at deciphering fundamental mechanisms ruling the behaviour of pollutants in ecosystems. Applying this knowledge to current environmental issues leads to the remediation of environmental media, and to new, low energy, low emission, sustainable processes. Nanotechnology applications for alternative energies such as solar power, fuel cells, hydrogen and lithium batteries are reviewed in the first section. Recent investigations on carbon nanotubes, nanocatalysts and cyclodextrins disclose unprecedented techniques to monitor and clean pollutants such as greenhouse gases, heavy metals, pesticides, pathogens occurring in water, air and soil. The second section reviews the risks for human health of critical pollutants such as endocrine disruptors, dioxins and heavy metals contaminating seafood and sediments. An exhaustive review of DDT isomers reveals unexpected mechanisms of DDT transfer to fishes. A chapter on pollutant geochronology using river sedimentary archives provides novel insights on pollution history since the beginning of the anthropocene. This book will be a valuable source of information for engineers and students developing novel applied techniques to monitor and clean pollutants in air, wastewater, soils and sediments.

Download or read book Chemical Instrumental Approaches to the Evaluation of Wine Chemistry written by Rosa Perestrelo and published by MDPI. This book was released on 2020-05-27 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wine is a widely consumed beverage due to its unique and pleasant sensory properties. Wine is composed of more than one thousand chemical compounds (e.g., alcohols, esters, acids, terpenoids, phenolic compounds, flavonoids, anthocyanins, minerals, and vitamins, among others) resulting from several chemical and biochemical processes. Microextraction techniques in tandem with high-resolution analytical instruments have been applied by wine researchers to expand the knowledge of wine’s chemical composition with the purposes of improving wine quality, supporting winemaker decisions related to the winemaking process, and guaranteeing the authenticity of wine. As a result, we proposed “Chemical/Instrumental Approaches to the Evaluation of Wine Chemistry” as a topic for a Special Issue in Molecules. This Special Issue aims to provide an update on state-of-the-art extraction procedures (e.g., solid-phase microextraction (SPME)) and analytical tools (e.g., nuclear magnetic resonance (NMR), inductively coupled plasma mass spectrometry (ICP-MS), ultra-performance liquid chromatography tandem mass spectrometry (UPLC-MS/MS)), emphasizing their use as suitable platforms for the establishment of the chemical composition of wine (volatomic profile, antioxidants, phenolic pattern, and elemental composition, among others). Information related to wine sensorial properties, contaminants, authenticity, and chemometric tools used for data treatment are described in this Issue.
