Molecules and Medicine delves into the discovery, application, and mode of action of more than one hundred of the most significant molecules now in use in modern medicine. Molecule structures and shapes are shown for all of these medicines. The opening sections of the book provide a unique, clear, and concise introduction which enables the reader to understand chemical formulas.
Water in the proximity of a surface (interfacial water) is abundant
on the earth. It is involved in various physical and chemical
processes and crucial for biological function. Despite numerous
studies of interfacial water, systematic analysis of its properties
is missing in scientific literature. This book is a first
comprehensive review of experimental and simulation studies of
water in various confining environments, such as hydrophilic and
hydrophobic surfaces, surfaces of biomolecules, porous media, etc.
Systematic analysis of interfacial and confined water is based on
the firm physical ground, which accounts for variety of the
thermodynamic states of water near the surface, surface phase
transitions, surface critical behaviour, effect of confinement on
the bulk and surface phase transitions of water, clustering and
formation of a spanning hydrogen-bonded water network via
percolation transition. This allows distinguishing between
universal features, common for all fluids, and some specific water
properties, related to intermolecular hydrogen bonds. Special
attention is paid to the properties of hydration water, which
covers biomolecules and enables their biological activity. This
book provides readers with basic information on interfacial and
confined water, which will be useful for scientists and engineers
working in the fields of bioscienses, nanociences and
nanotechnologies.

This book focuses on the characterization of the amorphous phase of polymers, whether they are pure amorphous or semi-crystalline ones, above Tg or below Tg, by studying the relaxation of dipoles and space charges naturally found in their structure after they have been activated by the application of a voltage field. The experimental deconvolution of the relaxation modes responsible for internal motion in the amorphous phase is coupled with a mathematical procedure (Thermal-Windowing Deconvolution-TWD) that leads to the understanding of their coupling characteristics which, it is shown, relate to the state of the material itself, for instance its non-equilibrium state or its internal stress for matter belonging to interfaces between aggregated or dispersed phases. Describes quantitatively the Thermal Stimulated Depolarization techniques of polymer characterization (TSD, TWD), i.e. how to decouple the relaxation modes collectively interacting (interactive coupling) and relate it to the thermodynamic properties of the amorphous phase. Understands the results of depolarization in terms of the new physics of polymer interactions: the Dual-Phase model, here applied to the dipoles-space charge dynamics. Provides a roaster of CASE STUDIES: practical applications of the TSD and TWD characterization techniques to describe coupled molecular motions in resins, medical tissues, wood, blends and block copolymers interfaces, rubbers, can coatings, internal stress in molded parts, etc
During the past 30 years, the field of alkene polymerization over
transition metal catalysts underwent several major changes:
A classical metastable state possesses a local free energy minimum
at infinite sizes, but not a global one. This concept is phase size
independent. We have studied a number of experimental results and
proposed a new concept that there exists a wide range of metastable
states in polymers on different length scales where their
metastability is critically determined by the phase size and
dimensionality. Metastable states are also observed in phase
transformations that are kinetically impeded on the pathway to
thermodynamic equilibrium. This was illustrated in structural and
morphological investigations of crystallization and mesophase
transitions, liquid-liquid phase separation, vitrification and gel
formation, as well as combinations of these transformation
processes. The phase behaviours in polymers are thus dominated by
interlinks of metastable states on different length scales. This
concept successfully explains many experimental observations and
provides a new way to connect different aspects of polymer physics.
Condensed-Phase Molecular Spectroscopy and Photophysics An introduction to one of the fundamental tools in chemical research--spectroscopy and photophysics in condensed-phase and extended systems Condensed-Phase Molecular Spectroscopy and Photophysics comprehensively covers radiation-matter interactions for molecules in condensed phases along with metallic and semiconductor nanostructures, examining optical processes in extended systems such as metals, semiconductors, and conducting polymers and addressing the unique optical properties of nanoscale systems. The text differs from others through its emphasis on the molecule-environment interactions that strongly influence spectra in condensed phases, including spectroscopy and photophysics of molecular aggregates, molecular solids, and metals and semiconductors, as well as more modern topics such as two-dimensional and single-molecule spectroscopy. To aid in reader comprehension, the text includes case studies and illustrated examples. An online manual with solutions to the problems in the book is available to all readers on a companion website. Condensed-Phase Molecular Spectroscopy and Photophysics begins with an introduction to quantum mechanics that sets a solid foundation for understanding the text's subsequent topics, including: Electromagnetic radiation and radiation-matter interactions, molecular vibrations and infrared spectroscopy, and electronic spectroscopy Photophysical processes and light scattering, nonlinear and pump-probe spectroscopies, and electron transfer processes Basic rotational spectroscopy and statistical mechanics, Raman scattering, 2D and single-molecule spectroscopies, and time-domain pictures of steady-state spectroscopies Time-independent quantum mechanics, statistical mechanics, group theory, radiation-matter interactions, and system-bath interactions Atomic spectroscopy, photophysical processes, light scattering, nonlinear and pump-probe spectroscopies, two-dimensional spectroscopies, and metals and plasmons Written for researchers and upper-level undergraduate and graduate courses in physical and materials chemistry, Condensed-Phase Molecular Spectroscopy and Photophysics is a valuable learning resource that is uniquely designed to equip readers to solve a broad array of current problems and challenges in the vast field of chemistry.

In this book, the author focuses on exploring new organocatalytic transformations under operationally simple and environmentally friendly reaction conditions. Two new types of catalytic reactions promoted by N-heterocyclic carbenes (NHCs) are described. The oxa- and azacycle-forming reactions of sulfonylalkynols and sulfonylalkynamides are broadly considered to be a new type of activation mode in NHC chemistry, wherein the bond formation with internal O- and N-nucleophiles occurs at the -position of the propargyl sulfones with 1,2-sulfonyl migration. The resulting oxa- and azacycles are core structures in many biologically significant compounds and medicinally important agents. In addition, the book develops the chiral NHC-catalyzed kinetic resolution of -hydroxy carboxylic acid derivatives based on chiral recognition of the substrate-cocatalyst complex. In this carboxylate cocatalyst-assisted chiral acylation, the reaction rate acceleration and selectivity enhancement are interpreted in terms of the reversible complexation of the substrate and carboxylate cocatalyst, which is verified by control experiments and measured using analytical methods. The findings described here reveal a promising new aspect of not only NHC catalysis but also identifying novel catalysis systems.
