In this book, the major paradigm-shifting discoveries made in the past century on key cellular nanomachines are described in great detail: their complex yet precise and elegant design and function, as well as the diseases linked to their dysfunction and the therapeutic approaches to overcome them. The major focus of this book is the "porosome" nanomachine, the universal secretory portal in cells. This is an ideal book for students, researchers, and professionals in the fields of nanoscience and nanotechnology.

Recent advances in experimental techniques now enable researchers to produce in a laboratory clusters of atoms of desired composition from any of the elements of the periodic table. This has created a new area of research into novel materials since clusters cannot be regarded either as a "large" molecule or as a fragment of the bulk. Both experimental and theoretical studies are revealing unusual properties that are not ob served in solid state environments. The structures of micro-clusters are found to be significantly distorted from the most symmetric arrangement, some even exhibiting pentagonal symmetry commonly found in icosahedric structures. The unusual stability of certain clusters, now described as "magic number species," shows striking similarities with the nuclear shell structure. The relative stabilities of clusters depend not only on the composition of the clusters but also on their charged states. The studies on spontaneous fragmentation of mUltiply charged clusters, commonly referred to as Coulomb explosion, illustrate the role of electronic bonding mechanisms on stability of clusters. The effect of foreign atoms on geometry and stability of clusters and the interaction of gas atoms with clusters are showing promise for an indepth understanding of chemisorption and catalysis. The magnetic and optical properties are dependent not only on cluster size but also on its geometry. These findings have the potential for aiding industry in the area of micro-electronics and catalysis."

Hydrogen is the smallest impurity atom that can be implanted in a metallic host. Its small mass and strong interaction with the host electrons and nuclei are responsible for many anomalous and interesting solid state effects. In addition, hydrogen in metals gives rise to a number of technological problems such as hydrogen embrittlement, hydrogen storage, radiation hardening, first wall problems associated with nuclear fusion reactors, and degradation of the fuel cladding in fission reactors. Both the fundamental effects and applied problems have stimulated a great deal of inter est in the study of metal hydrogen systems in recent years. This is evident from a growing list of publications as well as several international conferences held in this field during the past decade. It is clear that a fundamental understanding of these problems re quires a firm knowledge of the basic interactions between hydrogen, host metal atoms, intrinsic lattice defects and electrons. This understanding is made particularly difficult by hyrogen's small mass and by the large lattice distortions that accompany the hydrogenation process. The purpose of the "International Symposium on the Electronic Structure and Properties of Hydrogen in Metals" held in Richmond, Virginia, March 4-6, 1982 was to increase our fundamental under standing of hydrogen in metals. Such knowledge is essential in solving technologically important questions. The symposium con sisted of twenty-two invited papers and seventy-two contributed poster presentations and attracted nearly 150 participants from thirteen countries. The proceedings of this symposium constitute this book."

Understanding live cells at the single molecule level is the most important and single major challenge facing biology and medicine today. Over the past 15 years, there has been a renewed understanding of living cells at the molecular level. Atomic Force Microscopy, Laser Force Microscopy, single secretory vesicle patch clamp studies, highresolution electron microscopy, and x-ray diffraction, are some of the tools now being used to unravel the intricacies of a living cell at the molecular level. Opening with an explanation of Materials and Methods, NanoCellBiology then moves through discussions of porosome discovery, calcium and SNARE-induced fusion, and vesicle swelling before winding up in a final chapter of conclusions and future studies. Succinctly packaged as SpringerBrief, this book is a must for those studying or conducting research in cell biology, biochemistry or nanobiology/nanotechnology.This book will be invaluable to faculty & graduate students involved in Nano Courses; Cell Biology Courses; Biophysics Courses; and Biochemistry Courses as well as practicing Cell Biologists, Biochemists and BioPhysicists.

Nano-Scale Materials - From Science to Technology

Many of the observed electronic properties of condensed matter systems such as clusters of atoms, solids with long or short range order (amorphous and liquid metals) are governed by the local atomic arrangements around the probe site. The topics in this important volume include: Molecules and clusters; Point defects and defect complexes in solids; Hydrogen and positive muons in metals and semiconductors; Disordered solids and liquid metals; Diffusion and clustering in bulk, on surfaces; and other restricted geometry; High temperature superconductors including C60 assembled materials.

This book provides a comprehensive understanding of the discovery of a new cellular structure the "porosome," which is the universal secretory machinery in cells; the protein assembly, biomineralization, and biomolecular interactions; the molecular evolution of protein structure; the use of magnetic nanoparticles for transformative application in medicine and therapy, and the new and novel imaging approach of electrical impedance spectroscopy in biology. It be used for college courses in nanomedicine, nano cell biology, advanced nanotechnology, and biotechnology at the undergraduate and graduate level.
