Many Electron Atoms

Ebook "Many-body methods for atoms, molecules and clusters" provides an introduction to many-body methods for applications in quantum chemistry. These methods, originating in field-theory, offer an alternative to conventional quantum-chemical approaches to the treatment of the many-electron problem in molecules.

Ebook "Reduced-densitymatrix mechanics: With application to many-electron atoms and molecules" is divided into five related parts. Part I contains historical introductions by John Coleman and Mitja Rosina. Part II discusses the variational calculation of the 2-RDM including the development of a systematic hierarchy of N-representability conditions known as the positivity conditions and the design of effective semidefinite-programming algorithms for solving the 2-RDM optimization problem.

Ebook "Electron-atom collisions (Cambridge monographs on atomic, molecular, and chemical physics - Volume 5)" is a comprehensive introduction to electron-atom collisions, covering both theory and experiment. The interaction of electrons with atoms is the field that most deeply probes both the structure and reaction dynamics of a many-body system. The book begins with a short account of experimental techniques of cross-section measurement.

Nanoclusters have been emerging as potential building blocks for advanced nanostructured materials with desired catalytic, magnetic, and electronic properties. However, determining the structure of doped atomic clusters encounters many difficulties. A powerful approach to assign the ground state geometries of atomic clusters has been the comparison the recorded vibrational infrared spectra with the corresponding computed ones.

Graphene Quantum Dots (GQDs) are a type of material with a width of several nanometers (nm) and a thickness of a single layer or a few layers of carbon (C) atoms organized in hexagonal shape like a beehive. Since the lattice structure of GQDs only includes carbon atoms, they are a nanomaterial that is friendly to the environment and humans. They have many applications, with one of the main uses being a novel antimicrobial agent.

Amines are organic derivatives of ammonia with one or more alkyl or aryl groups bonded to the nitrogen atom. As a class, amines include some of the most important biological compounds. Amines serve many functions in living organisms, such as bioregulation, neurotransmission, and defense against predators. This chapter draw and name amines, and use spectral information to determine their structures; compare the basicity of amines with other common bases, and explain how their basicity varies with hybridization, aromaticity, resonance, and induction.

The first two chapters of the text cover a variety of topics that you need to get started with your study of organic chemistry. Chapter 1 reviews the topics from general chemistry that will be important to your study of organic chemistry. The chapter starts with a description of the structure of atoms and then proceeds to a description of the structure of molecules. Molecular orbital theory is introduced. Acid–base chemistry, which is central to understanding many organic reactions, is reviewed.

Many proteins and peptides can form amyloid-like structures bothin vivo andin vitro. Although strikingly similar fibrillar structures can be observed across a variety of amino acid sequences, the fibrils formed often exhibit a stunning wealth of polymorphisms at the level of electron or atomic force microscopy.

This book is written primarily to engineering students in the fields of basic chemistry, environmental chemistry, food production, chemical and biochemical engineering who in the beginning of their university studies receive education in inorganic chemistry and applied chemistry in general. The aim of this book is to explain and clarify important terms and concepts which the students are supposed to be familiar with. The book can not replace existing educational textbooks but it gives a great supplement to the education within chemistry.

Amorphous materials have attracted much attention in the last two decades. The first reason for this is their potential industrial applications as suitable materials for fabricating devices, and the second reason is the lack of understanding of many properties of these materials, which are very different from those of crystalline materials. Some of their properties are different even from one sample to another of the same material.

Nanotechnology in Biology and Medicine is intended to serve as an authoritative reference for a wide audience involved in research, teaching, learning, and practice of nanotechnology in life sciences. Nanotechnology, which involves research on and the development of materials and species at length scales between 1 to 100 nm, has been revolutionizing many important scientific fields ranging from biology to medicine. This technology, which is at the scale of the building blocks of the cell, has the potential of developing devices smaller and more efficient than anything currently available.
