Полный вариант заголовка: «Hydrogeologie : ou recherches sur l'influence qu'ont les eaux sur la surface du globe terrestre; sur les causes de l'existence du bassin des mers, de son deplacement et de son transport successif sur les differens points de la surface de ce globe; enfin sur les changemens que les corps vivans exercent sur la nature et l'etat de cette surface / par J. B. Lamarck».


Hydrogen Diffusion and Porosity Formation In Aluminium Hydrogen Diffusion and Porosity Formation In Aluminium

Автор: Ulanovskiy I. B.

Год издания: 

This book presents experimental data obtained by the author on hydrogen permeability, solubility and diffusion of hydrogen in aluminum and its alloys, as well as on porosity formation in aluminum and its alloys. The author offers new techniques for determining the surface tension of solid metals and the hydrogen content in aluminum alloys containing components with high vapour pressures. The book also considers the theory of porosity formation in metals. For the first time ever, the author presents a technique for metals and alloys treatment securing the removal of gases and eliminating gas unsoundness, known as the ‘hot isostatiс pressing technique’. The author proposes a technology, which ensures cutting down flaws caused by gas cavities in aluminum aircraft shell plates.


Engineered Carbohydrate-Based Materials for Biomedical Applications. Polymers, Surfaces, Dendrimers, Nanoparticles, and Hydrogels Engineered Carbohydrate-Based Materials for Biomedical Applications. Polymers, Surfaces, Dendrimers, Nanoparticles, and Hydrogels

Автор: Ravin Narain

Год издания: 

This book addresses the need for a comprehensive book on the design, synthesis, and characterization of synthetic carbohydrate-based polymeric materials along with their biological applications. The first two chapters cover the synthesis and self-assembly of glycopolymers and different techniques for creating these synthetic polymers. Subsequent chapters account for the preparation of block copolymers, branched glycopolymers, glycosurfaces, glycodendrimers, cationic glycopolymers, bioconjugates, glyconanoparticles and hydrogels. While these chapters comprehensively review the synthetic and characterization methods of those carbohydrate-based materials, their biological applications are discussed in detail.


Innovative Catalysis in Organic Synthesis. Oxidation, Hydrogenation, and C-X Bond Forming Reactions Innovative Catalysis in Organic Synthesis. Oxidation, Hydrogenation, and C-X Bond Forming Reactions

Автор: Pher Andersson G.

Год издания: 

C-H, C-O, C-C, and C-Heteroatom bond forming processes by using metal-ligand approaches for the synthesis of organic compounds of biological, pharmacological and organic nanotechnological utility are the key areas addressed in this book. Authored by a European team of leaders in the field, it brings together innovative approaches for a variety of catalysis reactions and processes frequently applied in organic synthesis into a handy reference work. It covers all major types of catalysis, including homogeneous, heterogeneous, and organocatalysis, as well as mechanistic and computational studies. Special attention is paid to the improvements in efficiency and sustainability of important catalytic processes, such as selective oxidations, hydrogenation, and cross-coupling reactions, and to their utilization in industry. The result is a valuable resource for advanced researchers in both academia and industry, as well as graduate students in organic chemistry aiming for chemo-, regio- or stereoselective synthesis of organic compounds by using novel catalytic systems.


Hydrogel Micro and Nanoparticles Hydrogel Micro and Nanoparticles

Автор: Lyon L. Andrew

Год издания: 

The book provides experienced as well as young researchers with a topical view of the vibrant field of soft nanotechnology. In addition to elucidating the underlying concepts and principles that drive continued innovation, major parts of each chapter are devoted to detailed discussions of potential and already realized applications of micro- and nanogel- based materials. Examples of the diverse areas impacted by these materials are biocompatible coatings for implants, films for controlled drug release, self-healing soft materials and responsive hydrogels that react to varying pH conditions, temperature or light.
