This collection of texts written by well-recognised specialists was constituted having in view these important directions of actual research. Sustainable economical growth requires safe resources of raw materials for the industrial production. Today's most frequently used industrial raw material, petroleum, is neither sustainable, because limited, nor environmentally friendly. While the economy of energy can be based on various alter-native raw materials, such as wind, sun, water, biomass, as well as nuclear fission and fusion, the economy of substances is fundamentally depending on biomass, in particular biomass of plants. In the last decades because of the crude oil and other natural resources crisis, a new alternative has been proposed consisting in utilisation of renewable natural resources as feedstock and fuel, among which the biomass is the most promising.

Polyampholytes are unique polymers containing acid/base and/or anionic/cationic groups in the main or side chains. Water-soluble and water-swelling polyampholytes exhibit properties that provide broad potential as structural biomaterials, drug delivery and chemo-mechanical systems, biosensors, energy storage devices, supercapacitors, and actuators, among others. This monograph reviews the innovative studies in this field over the past two decades, with the aim to analyze and systematize the literature in the context of emerging technologies. Offers a multidisciplinary perspective covering polyampholytes, polybetaines, and polyzwitterions in nanotechnology, biotechnology, medicine, catalysis, environment protection, and oil industry applications Demonstrates a wide range of applications for these materials with enough depth to provide critical fundamental knowledge for new researchers in the field Discusses polyampholyte-protected and gel-immobilized metal nanoparticles and enzymes that catalyze reactions of hydrolysis, decomposition, hydrogenation, and oxidation of various substrates in batch-type and continuous flow–type reactors Highlights the remaining persistent challenges in the development and application of these materials This book will appeal to readers who conduct materials research for biomedical, water treatment, and environmental remediation applications.

High pressure technology is used so extensively that it is almost impossible to catalogue the manyways in which our lives are enhanced by it. From pneumatic tires and household water supplies tomaterials such as crystals, plastics, and even synthetic diamond, there are countless materialsfabricated or shaped using high pressure technology. High Pressure Technology (in two volumes)presents the most up-to-date information available on the main features of this broad technology andthe processes which utilize it.Volume I: Equipment Design, Materials, and Properties covers three broad areas: the general operationof high pressure systems, including standard operating procedures and safety codes and measures;the technology of high pressure systems, such as components, vessel design, and materials of construction;and applied science at high pressure, including the properties of fluids and solids andmechanical properties. Volume II: Applications and Processes covers processes at high pressure andencompasses such topics as: catalytic chemical synthesis; polymerization; phase changes; criticalphenomena; liquefaction of gases; synthesis of single-crystal materials, diamond, and superhardmaterials; isostatic compacting; isostatic hot-pressing; hydrostatic forming of metals; hydraulic cutting;and applications of shock techniques.Written by recognized authorities in industry, government laboratories, and universities, High PressureTechnology is essential reading for the industrial practitioner, high pressure engineer, and researchscientist. In addition, it is a valuable textbook for students in mechanical, chemical, and materialsengineering courses.

Solvents and ionic liquids are ubiquitous within our whole life since ancient times and their effects are actually being studied through basic sciences like Chemistry, Physics and Biology as well as being researched by a large number of scientific disciplines.This book represents an attempt to present examples on the utility of old and new solvents and the effects they exercise on several fields of academic and industrial interest. The first section, Solvents, presents information on bio-solvents and their synthesis, industrial production and applications, about per and trichloroethylene air monitoring in dry cleaners in the city of Sfax (Tunsia) and on the synthesis of polyimides using molten benzoic acid as the solvent. The second section, Ionic Liquids, shows information about the synthesis, physicochemical characterization and exploration of antimicrobial activities of imidazolium ionic liquid-supported Schiff base and its transition metal complexes, the technology of heterogenization of transition metal catalysts towards the synthetic applications in an ionic liquid matrix, the progress in ionic liquids as reaction media, monomers, and additives in high-performance polymers, a pre-screening of ionic liquids as gas hydrate inhibitor via application of COSMO-RS for methane hydrate, the extraction of aromatic compounds from their mixtures with alkanes from ternary to quaternary (or higher) systems and a review on ionic liquids as environmental benign solvent for cellulose chemistry. The final section, Solvent Effects, displays interesting information on solvent effects on dye sensitizers derived from anthocyanidins for applications in photocatalysis, about the solvent effect on a model of SNAr reaction in conventional and non-conventional solvents, and on solvent effects in supramolecular systems.

Polymer Science: A Materials Science Handbook, Volume 2 focuses on the chemical structures of polymers, as well as the processes of friction and wear, adhesion, radiation, spectroscopy, and nuclear magnetic resonance. The handbook first tackles the processes of adhesion and friction and wear, including factors affecting adhesion, theories of adhesion, and interfacial and cohesive failure. The book also reviews polymer solutions and fractionation, polyelectrolytes, and electrical properties of polymers. The publication takes a look at the dielectric properties of polymers and far infrared spectra of polymers. Discussions focus on the basic theory of dielectric behavior of small molecules; molecular theories of relaxation in polymers; dielectric behavior and relaxation of polymer solutions; theory of the absorption and dispersion of electromagnetic waves in condensed media; and absorption spectroscopy in the far infrared. The text also reviews nuclear magnetic resonance, radiation effects in polymers, and identification and analysis of plastic materials. The handbook is a dependable reference for readers interested in polymer science.
