Summary : 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. * Comprehensive review and analysis of interfacial and confined water * Updates and informs practitioners and students on all the latest developments in the field * Written by leading scholars and industry experts

Summary : This thesis presents a series of experimental techniques based on scanning probe microscopy, which make it possible access the degree of freedom of protons both in real and energy space. These novel techniques and methods allow direct visualization of the concerted quantum tunneling of protons within the hydrogen-bonded network and quantification of the quantum component of a single hydrogen bond at a water–solid interface for the first time. Furthermore, the thesis demonstrates that the anharmonic quantum fluctuations of hydrogen nuclei further weaken the weak hydrogen bonds and strengthen the strong ones. However, this trend was reversed when the hydrogen bond coupled to the local environment. These pioneering findings substantially advance our understanding of the quantum nature of H bonds at the molecular level.

Summary : In spite of the enticing promises of the post-genomic era, the pharmaceutical world is in a state of disarray. Drug discovery seems now riskier and more uncertain than ever. Thus, projects get routinely terminated in mid-stage clinical trials, new targets are getting harder to find, and successful therapeutic agents are often recalled as unanticipated side effects are discovered. Exploiting the huge output of genomic studies to make safer drugs has proven to be much more difficult than anticipated. More than ever, the lead in the pharmaceutical industry depends on the ability to harness innovative research, and this type of innovation can only come from one source: fundamental knowledge. This book squarely addresses this crucial problem since it introduces fundamental discoveries in basic biomolecular research that hold potential to broaden the technological base of the pharmaceutical industry. The book takes a fresh and fundamental look at the problem of how to design an effective drug with controlled specificity. Since the novel transformative concepts are unfamiliar to most practitioners, the first part of this book explains matters very carefully starting from a fairly elementary physico-chemical level. The second part of the book is devoted to practical applications, aiming at nothing less than a paradigm shift in drug design. This book is addressed to scientists working at the cutting edge of research in the pharmaceutical industry, but the material is at the same time accessible to senior undergraduates or graduate students interested in drug discovery and molecular design.

Summary : Water is perhaps the most important chemical substance known. Without it, the very existence of life would be questionable. Yet its detailed structure and behaviour in the condensed phase and the interfaces between the condensed phase and its environment remain somewhat controversial. Indeed as ever more sophisticated and novel experimental and theoretical tools are applied to the study of bulk liquid water and ice and its interfaces, it is becoming increasingly clear that this disparate information could heat the debate on the phase and interface behaviour of water rather than cool it! This book plans to achieve a unification of views towards the goal of understanding the microscopic structure and behaviour of condensed phases of water at interfaces and progressing into the bulk.

Summary : Presents a multi-disciplinary perspective on the physics of life and the particular role played by lipids and the lipid-bilayer component of cell membranes. Emphasizes the physical properties of lipid membranes seen as soft and molecularly structured interfaces. By combining and synthesizing insights obtained from a variety of recent studies, an attempt is made to clarify what membrane structure is and how it can be quantitatively described. Shows how biological function mediated by membranes is controlled by lipid membrane structure and organization on length scales ranging from the size of the individual molecule, across molecular assemblies of proteins and lipid domains in the range of nanometers, to the size of whole cells. Applications of lipids in nano-technology and biomedicine are also described.

Summary : Properties and applications of high surface area materials depend on interfacial phenomena, including diffusion, sorption, dissolution, solvation, surface reactions, catalysis, and phase transitions. Among the physicochemical methods that give useful information regarding these complex phenomena, nuclear magnetic resonance (NMR) spectroscopy is the most universal, yielding detailed structural data regarding molecules, solids, and interfaces. Nuclear Magnetic Resonance Studies of Interfacial Phenomena summarizes NMR research results collected over the past three decades for a wide range of materials—from nanomaterials and nanocomposites to biomaterials, cells, tissues, and seeds. This book describes the applications of important new NMR spectroscopic methods to a variety of useful materials and compares them with results from other techniques such as adsorption, differential scanning calorimetry, thermally stimulated depolarization current, dielectric relaxation spectroscopy, infrared spectroscopy, optical microscopy, and small-angle and wide-angle x-ray scattering. The text explores the application of NMR spectroscopy to examine interfacial phenomena in objects of increasing complexity, beginning with unmodified and modified silica materials. It then describes properties of various mixed oxides with comparisons to individual oxides and also describes carbon materials such as graphite and carbon nanotubes. Chapters deal with carbon–mineral hybrids and their mosaic surface structures, and interfacial phenomena at the surface of natural and synthetics polymers. They also explore a variety of biosystems, which are much more complex, including biomacromolecules (proteins, DNA, and lipids), cells and tissues, and seeds and herbs. The authors cover trends in interfacial phenomena investigations, and the final chapter describes NMR and other methods used in the book. This text presents a comprehensive description of a large array of hard and soft materials, allowing the analysis of the structure–property relationships and generalities on the interfacial behavior of materials and adsorbates.

Summary : The ill-defined pore morphologies and connectivities of conventional membrane materials has hampered a clear understanding of the relationship between pore geometry, pore interfacial chemistry, and ultimate membrane performance. A host of empirical studies have suggested that membranes with sub-5 nm pores are ideal for applications in water purification or ion transport. Formed by the aqueous self-assembly of ionic amphiphiles, lyotropic liquid crystal (LLC) network (N) phases are candidate membrane materials by virtue of their percolating, sub-3 nm pores. The well-defined pore structures and interfacial chemical functionalities of LLCs also make them an attractive platform for fundamental studies of water-mediated H+ transport and water dynamics in nanoporous materials. Recent studies have demonstrated that dicarboxylate gemini amphiphiles stabilize N-phase LLCs, yet their utility in practical applications remains untested. In this thesis, we explore amphiphile design criteria for the stabilization of N-phase LLCs and investigate how water dynamics depend on nanopore geometry and interfacial chemistry. We specifically investigate the ability of gemini amphiphiles to serve as "value-added" components that direct the self-assembly of conventional single-tail amphiphiles into N-phase LLCs as a function of gemini loading, molecular structure, and surfactant counterion identity. These studies reveal that the unique molecular conformations adopted by the dicarboxylate gemini amphiphiles enable them to function as highly anisotropic inclusions that drive LLC N-phase formation. We further utilize LLC self-assemblies as a platform to explore the relationship between H+ conductivity and nanopore geometry. Through the rational design and synthesis of a gemini bis(sulfonic acid) amphiphile and a highly branched sulfonic acid amphiphile, we investigate H+ conductivity in LLCs with either convex or concave nanopores, respectively. We observe that proton conductivity is maximized through intermediate-diameter nanopores and is further increased in convex nanopores. In order to understand this surprising result, we investigate confined water dynamics in the convex nanopores of gemini dicarboxylate LLCs using quasielastic neutron scattering (QENS). We find that water diffusion depends most sensitively on pore size or water content, but is also affected by the identity of the surfactant counterion. Subsequent studies of water dynamics in alkylsulfonate LLCs establish that water diffusion is systematically faster in sulfonated nanopores, and that, independent of pore interfacial chemistry, water diffusion is slower in convex nanopores. From these studies emerge new design criteria suggesting that membranes with convex nanopores may function as highly efficient ion transporting and water purification membranes.

Summary : Ice is one of the most abundant and environmentally important materials on Earth, and its unique and intriguing physical properties present fascinating areas of study for a wide variety of researchers. This book is about the physics of ice, by which is meant the properties of the material itself and the ways in which these properties are interpreted in terms of water molecules and crystalline structure. Although ice has a simple crystal structure its hydrogen bonding results in unique properties, which continue to be the subject of active research. In this book the physical principles underlying the properties of ice are carefully developed at a level aimed at pure and applied researchers in the field. Important topics like current understandings of the electrical, mechanical, and surface properties, and the occurrence of many different crystalline phases are developed in a coherent way for the first time. An extensive reference list and numerous illustrations add to the usefulness and readability of the text.
