This book is the most comprehensive treatment yet of the problems faced by the engineer caused by static electricity. Written in as non-technical a manner as possible, given the depth of the material, this book discusses the material from the beginner level to many advanced topics for engineers and designers. It discusses not only the harmful and damaging known effects of static electricity on electrical and electronic equipment, but the possible solutions and applications that can be used to stop it.

This new edition like the first edition provides a comprehensive and coherent account of static electric phenomena and concepts based on a mathematical-physical approach. It is intended for the nonspecialists interested in understanding the electrostatic concepts, and for the specialized engineer who may not be familiar with the basic fundamentals. This work has been updated to include new and expanded material on charge decay, charge neutralization by air ions, breakdown between conductors with different electrode geometry and a completely rewritten chapter on electrostatic measurements with special emphasis put on showing the difficulty in relating the voltage of a conductor with a measured field strength. Another important issue in this chapter is demonstrating that the concept of voltage can not be applied in connection with insulators. This ESD-handbook is written in an easy to read style similar to the approach taken in the author's "Mr. Static" column. Electrostatics, Second Edition is an essential reference work for the non-specialist because of the numerous examples that show the many ways static electricity makes itself known as a nuisance as well as the ways in which static electric effects can be used, from cleaning the air in an electrofilter to making photocopies.

Electrostatics at the Molecular Level

Elementary electrostatics lacks much of the richness of classical mechanics: electrostatics is essentially reduced to the calculation of the force on a point charge due to several other point charges at some different location.

Electrostatic forces are essential for the hierarchical structure of matter: electrons are bound to the atomic nucleus by electrostatic forces; atoms carry (partial) charges and ions with opposite charges attract and form (chemical) bonds. Small residual electrostatic forces between molecules allow them to form macroscopic structures such as crystals. Electrostatic interactions explain pseudo-forces used in popular computer programs used to model properties of atoms, molecules, and proteins. By beginning with the basics and then diving deeper into the topic, this book aims to familiarize the reader with electrostatic forces at the atomic and molecular level.

The two parts of this Memoir contain two separate but closely related papers. In the paper in Part A we study the correlation of holes in random lozenge (i.e., unit rhombus) tilings of the triangular lattice. More precisely, we analyze the joint correlation of these triangular holes when their complement is tiled uniformly at random by lozenges. We determine the asymptotics of the joint correlation (for large separations between the holes) in the case when one of the holes has side 1, all remaining holes have side 2, and the holes are distributed symmetrically with respect to a symmetry axis.Our result has a striking physical interpretation. If we regard the holes as electrical charges, with charge equal to the difference between the number of down-pointing and up-pointing unit triangles in a hole, the logarithm of the joint correlation behaves exactly like the electrostatic potential energy of this two-dimensional electrostatic system: it is obtained by a Superposition Principle from the interaction of all pairs, and the pair interactions are according to Coulomb's law.The starting point of the proof is a pair of exact lozenge tiling enumeration results for certain regions on the triangular lattice, presented in the second paper. The paper in Part B was originally motivated by the desire to find a multi-parameter deformation of MacMahon's simple product formula for the number of plane partitions contained in a given box. By a simple bijection, this formula also enumerates lozenge tilings of hexagons of side-lengths $a,b,c,a,b,c$ (in cyclic order) and angles of 120 degrees. We present a generalization in the case $b=c$ by giving simple product formulas enumerating lozenge tilings of regions obtained from a hexagon of side-lengths $a,b+k,b,a+k,b,b+k$ (where $k$ is an arbitrary non-negative integer) and angles of 120 degrees by removing certain triangular regions along its symmetry axis. The paper in Part A uses these formulas to deduce that in the scaling limit the correlation of the holes is governed by two dimensional electrostatics.

Recently, there has been a surge of activity to elucidate the behavior of highly charged soft matter and Coulomb fluids in general. Such systems are ubiquitous, especially in biological matter where the length scale and the strength of the interaction between highly charged biomolecules are governed by strong electrostatic effects. Several interesting limits have been discovered in the parameter space of highly charged many-particle Coulomb matter where analytical progress is possible and completely novel and unexpected results have been obtained. One of the challenges in highly charged matter is to correctly describe systems with finite coupling strength in the transition regime between weak and strong couplings. After studying the fluctuations of both, several theories have been developed that describe this experimentally highly relevant regime. At the same time, computer simulation algorithms and computing power have advanced to the level where all-ion simulations, including many-body and polarization effects, are possible; the new theories thus can be subjected to numerical confirmation. Another important question is the effect of the structural disorder on electrostatic interactions. It has recently been demonstrated, both theoretically and experimentally, that charge disorder can impose long-range interaction between charged or even uncharged surfaces. These interactions might become very significant in biological processes. Filling a void in the literature, this volume cross-pollinates different theoretical and simulation approaches with new experiments and ties together the low temperature, high coupling constant, and disorder parameters in a unified description of the electrostatic interactions, which largely determine the stability and conformations of most important biological macromolecules. With striking graphical illustrations, the book presents a unified view of the current advances in the field of Coulomb (bio)colloidal systems, building on previous literature that summarized the field over 20 years ago. Leading scientists in the field offer a detailed introduction to different modern methods in statistical physics of Coulomb systems. They detail various approaches to elucidate the behavior of strongly charged soft matter. They also provide experimental and theoretical descriptions of disorder effects in Coulomb systems, which have not been discussed in any other book.

As computational hardware continues to develop at a rapid pace, quantitative computations are playing an increasingly essential role in the study of biomolecular systems. One of the most important challenges that the field faces is to develop the next generation of computational models that strike the proper balance of computational efficiency and accuracy, so that the problems of increasing complexity can be tackled in a systematic and physically robust manner. In particular, properly treating intermolecular interactions is fundamentally important for the reliability of all computational models. In this book, contributions by leading experts in the area of biomolecular simulations discuss cutting-edge ideas regarding effective strategies to describe many-body effects and electrostatics at quantum, classical, and coarse-grained levels. The goal of the book is to not only provide an up-to-date snapshot of the current simulation field but also stimulate exchange of ideas across different sub-fields of modern computational (bio)chemistry. The text will be a useful reference for the biomolecular simulation community and help attract talented young students into this exciting frontier of research.
