Membrane Hydration - The Role of Water in the Structure and Function of Biological Membranes (Hardcover, 1st ed. 2015): E.... Membrane Hydration - The Role of Water in the Structure and Function of Biological Membranes (Hardcover, 1st ed. 2015)
E. Anibal Disalvo
R4,581 R3,726 Discovery Miles 37 260 Save R855 (19%) Ships in 10 - 15 working days

This book is about the importance of water in determining the structure, stability and responsive behavior of biological membranes. Water confers to lipid membranes unique features in terms of surface and mechanical properties. The analysis of the hydration forces, plasticiser effects, controlled hydration, formation of microdomains of confined water suggests that water is an active constituent in a water-lipid system. The chapters describe water organization at the lipid membrane-water interphase, the water penetration, the long range water structure in the presence of lipid membranes by means of X-ray and neutron scattering, general polarization, fluorescent probes, ATR-FTIR and near infrared spectroscopies, piezo electric methods, computer simulation and surface thermodynamics. Permeation, percolation, osmotic stress, polarization, protrusion, sorption, hydrophobicity, density fluctuations are treated in detail in self-assembled bilayers. Studies in lipid monolayers show the correlation of surface pressure with water activity and its role in peptide and enzyme interactions. The book concludes with a discussion on anhydrobiosis and the effect of water replacement in microdomains and its consequence for cell function. New definitions of lipid/water interphases consider water not only as a structural-making solvent but as a mediator in signalling metabolic activity, modulating protein insertion and enzymatic activity, triggering oscillatory reactions and functioning of membrane bound receptors. Since these effects occur at the molecular level, membrane hydration appears fundamental to understand the behavior of nano systems and confined environments mimicking biological systems. These insights in structural, thermodynamical and mechanical water properties give a base for new paradigms in membrane structure and function for those interested in biophysics, physical chemistry, biology, bio and nano medicine, biochemistry, biotechnology and nano sciences searching for biotechnological inputs in human health, food industry, plant growing and energy conversion.

Thermodynamics of Crystalline States (Hardcover, 2nd ed. 2013): Minoru Fujimoto Thermodynamics of Crystalline States (Hardcover, 2nd ed. 2013)
Minoru Fujimoto
R4,080 R3,473 Discovery Miles 34 730 Save R607 (15%) Ships in 10 - 15 working days

Thermodynamics is a well-established discipline of physics for properties of matter in thermal equilibrium with the surroundings. Applying to crystals, however, the laws encounter undefined properties of crystal lattice, which therefore need to be determined for a clear and well-defined description of crystalline states. "Thermodynamics of Crystalline States" explores the roles played by order variables and dynamic lattices in crystals in a wholly new way.
The book begins by clarifying basic concepts for stable crystals. Next, binary phase transitions are discussed to study collective motion of order variables, as described mostly as classical phenomena. New to this edition is the examination of magnetic crystals, where magnetic symmetry is essential for magnetic phase transitions. The multi-electron system is also discussed theoretically, as a quantum-mechanical example, for superconductivity in metallic crystals. Throughout the book, the role played by the lattice is emphasized and studied in-depth.
"Thermodynamics of Crystalline States" is an introductory treatise and textbook on mesoscopic phenomena in solid states, constituting a basic subject in condensed matter physics. While this book serves as a guide for advanced students in physics and material science, it can also be useful as a reference for all professionals in related fields.
Minoru Fujimoto is author of "Physics of Classical Electromagnetism "(Springer, 2007) and "The Physics of Structural Phase Transitions "(Springer, 2005)."

There are two main disciplines in catalysis research -- homogeneous and heterogeneous catalysis. This is due to the fact that the catalyst is either in the same phase (homogeneous catalysis) as the reaction being catalyzed or in a different phase (heterogeneous catalysis). Over the past decade, various approaches have been implemented to combine the advantages of homogeneous catalysis (efficiency, selectivity) with those of heterogeneous catalysis (stability, recovery) by the heterogenization of homogeneous catalysts or by carrying out homogeneous reactions under heterogeneous conditions.
This unique handbook fills the gap in the market for an up-to-date work that links both homogeneous catalysis applied to organic reactions and catalytic reactions on surfaces of heterogeneous catalysts. As such, it highlights structural analogies and shows mechanistic parallels between the two, while additionally presenting kinetic analysis methods and models that either work for both homogeneous and heterogeneous catalysis.
Chapters cover asymmetric, emulsion, phase-transfer, supported homogeneous, and organocatalysis, as well as in nanoreactors and for specific applications, catalytic reactions in ionic liquids, fluorous and supercritical solvents and in water. Finally, the text includes computational methods for investigating structure-reactivity relations.
With its wealth of information, this invaluable reference provides academic and industrial chemists with novel concepts for innovative catalysis research.
