This book was released on 2008-09-16 with total page 239 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book treats the different current as well as unusual and hitherto often unstudied physico-chemical and surface-thermodynamic properties of water that govern all polar interactions occurring in it. These properties include the hyper-hydrophobicity of the water-air interface, the cluster formation of water molecules in the liquid state and the concomitant variability of the ratio of the electron-accepticity to electron-donicity of liquid water as a function of temperature, T. The increase of that ratio with T is the cause of the increase in hydration repulsion ("hydration pressure) between polar surfaces upon heating, when they are immersed in water.The book also treats the surface properties of apolar and polar molecules, polymers, particles and cells, as well as their mutual interaction energies, when immersed in water, under the influence of the three prevailing non-covalent forces, i.e., Lewis acid-base (AB), Lifshitz-van der Waals (LW) and electrical double layer (EL) interactions. The polar AB interactions, be they attractive or repulsive, typically represent up to 90% of the total interaction energies occurring in water. Thus the addition of AB energies to the LW + EL energies of the classical DLVO theory of energy vs. distance analysis makes this powerful tool (the Extended DLVO theory) applicable to the quantitative study of the stability of particle suspensions in water. The influence of AB forces on the interfacial tension between water and other condensed-phase materials is stressed and serves, inter alia, to explain, measure and calculate the driving force of the hydrophobic attraction between such materials (the "hydrophobic effect), when immersed in water. These phenomena, which are typical for liquid water, influence all polar interactions that take place in it. All of these are treated from the viewpoint of the properties of liquid water itself, including the properties of advancing freezing fronts and the surface properties of ice at 0o C. - Explains and allows the quantitative measurement of hydrophobic attraction and hydrophilic repulsion in water - Measures the degree of cluster formation of water molecules - Discusses the influence of temperature on the cluster size of water molecules - Treats the multitudinous effects of the hyper-hydrophobicity of the water-air interface

Available in PDF, EPUB and Kindle. Book excerpt: The book presents the fantastic world of water in all its different forms, from liquid to ice and snow. This book is amply illustrated with a large number of beautiful pictures with. Water plays a unique role in chemistry. The special properties of water are due to hydrogen bonding between the H2O molecules. The hydrogen bond is of fundamental importance in biological systems since all living matter has evolved from and exists in an aqueous environment, and hydrogen bonds are involved in most biological processes. There is a hundred times more water molecules in our bodies than the sum of all the other molecules put together. The unique properties of water are of great importance in our daily life. The origin of these special properties is often not recognized. Even among chemists and physicists, the fundamental facts are not always known. In spite of very active research, there are still many questions to be answered about the structure of liquid water, for instance. The book differs from most books on water as it covers basic facts about structure and properties as well as the influence of these properties in our daily life. Why does ice float on water? Why is the maximum density of water at 4°C? The beauty of snow crystals is amply illustrated, and many of the pictures are unique.

This book was released on 2020-11-04 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: Top-down approaches are currently the main contributor of fabricating microelectronic devices. However, the prohibitive cost of numerous technological steps in these approaches is the main obstacle to further progress. Furthermore, a large number of applications necessitate fabrication of complex and ultra-small devices that cannot be made using these approaches. New approaches based on natural self-assembly of matter need to be developed to allow for fabrication of micro and nanoelectronic devices. Self-assembly of nanostructures is a dynamic field, which explores physics of these structures and new ways to fabricate them. However, the major problem is how to control the properties of the nanostructures resulting from low dimensionality. This book presents recent advances made to address this problem, and fabricate nanostructures using self-assembly.
