This volume documents the Proceedings of the 5th and 6th Symposia on Particles on Surfaces: Detection, Adhesion and Removal, held under the aegis of the Fine Particle Society in Chicago (May 6--9, 1996) and Dallas (April 1--3, 1998), respectively. The technical programs clearly reflected an interest and need to ameliorate the existing methods and to devise new and more efficient ways to detect, analyze and characterize particles on surfaces. The removal of particles from a host of surfaces was especially highlighted; the need to remove smaller and smaller particles was particularly underscored. All manuscripts included in this volume were properly peer reviewed and all were revised before inclusion in this volume. Thus, this book is not a mere collection of unreviewed papers, but represents information that has passed peer scrutiny. Furthermore, the authors of the 5th Symposium were asked to update the information. So, the information presented in this book should be as fresh and up-to-date as possible. This volume is divided into two parts: Part 1. General Papers and Part 2. Particle Adhesion and Removal. The topics covered include: high-sensitivity rapid detection of particles; detection of particles using evanescent wave scattering; particles on the backside of wafers; particle shedding from fluid-handling components; dynamics of particle adhesion; particle dispersion/aggregation; precision cleaning; and particle removal by surfactants, supercritical fluids, hydrodynamic forces, high-speed droplet impinging, megasonic, CO2 blasting, CO2 snow, argon aerosol, lasers, microcluster beams, brush and chemical-mechanical methods. This volume offers bountiful information and represent a current commentary on the R&D activity taking place in the area of particles on surfaces, particularly particle removal from a variety of surfaces.

Engström-Finean Biological Ultrastructure, Second Edition, looks upon biological phenomena essentially as patterns of physical and chemical events organized in space and time. It attempts to describe the spatial aspects of this organization, emphasizing in particular the fundamental roles of individual types of molecules. It also introduces a minimum background of fundamental structural information and of techniques so as to aid in the appreciation of the significance of experimental data. The plan of the book in the present edition remains unchanged but the tremendous advances of recent years have necessitated changes in emphasis in the treatment of methods and fundamentals of structure and a complete reappraisal of biological ultrastructure. Key topics discussed include methods in ultrastructural research, the principles of molecular structure; the role of proteins, nucleic acids, lipids, carbohydrates, mineral salts; and the role of ultrastructure in biology and medicine.

The past few years have witnessed the development of non-spherical metal nanoparticles with complex morphologies, which offer tremendous potential in materials science, chemistry, physics and medicine. Covering all important aspects and techniques of preparation and characterization of metal nanoparticles with controlled morphology and architecture, this book provides a sound overview - from the basics right up to recent developments. Renowned research scientists from all over the world present the existing knowledge in the field, covering theory and modeling, synthesis and properties of these nanomaterials. By emphasizing the underlying concepts and principles in detail, this book enables researchers to fully recognize the future research scope and the application potential of the complex-shaped metal nanoparticles, inspiring further research in this field.

This volume chronicles the proceedings of the Symposium on Particles on Surfaces: Detection, Adhesion and Removal held under the auspices of the Fine Particle Society in San Francisco, July 28-August 2, 1986. The study of particles on surfaces is extremely important in many areas of human endeavor (ranging from microelectronics to optics to biomedical). A complete catalog of modern precision and sophisticated technologies where particles on surfaces are of cardinal importance will be prohibitively long, but the following eclectic examples should underscore the concern about particles on a variety of surfaces. In the semiconductor world of shrinking dimensions, particles which, a few years ago, were cosmetically undesirable but functionally innocuous can potentially be killer defects now. As the device sizes get smaller, there will be more and more concern about smaller and smaller particles. In the information storage technology, the gap between the head and the disk is very narrow, and if a particle is trapped in the gap that can have very grave consequences. The implications of particulate contamination on sensitive optical surfaces is all too manifest. So the particulate contamination on surfaces is undesirable from functional, yield and reliability points of view. This symposium was organized with the following objectives in mind: to bring together active practitioners in this field; to provide a forum for discussion of the latest research and development activities in this area; to provide opportunity for cross-pollination of ideas; and to highlight topics which needed intensified effort.

There are two types of energy that exist within space : Dark Energy and Dark Matter. Dark Energy is a homogenous eternal potential energy that exists below zero degree kelvin temperature in absolute static equilibrium phase of energy. Dark Matter is the dynamic phase of Dark Energy above zero degree kelvin temperature as kinetic Energy. Smallest unit of kinetic energy particle is a one-dimensional photon and known as the God Particle. All elements are formed by these God particles. We, human beings are also made with baryonic hydrogen atoms arranged in elemental and molecular forms that are all made with God particles. Dark energy to Dark Matter conversion leads to contraction of energy space and Dark Matter to Dark Energy conversion leads to expansion of energy space like ice to water conversion and vice versa.
