  • Molecules, small structures composed of atoms, are essential substances for lives. However, we didn’t have the clear answer to the following questions until the 1920s: why molecules can exist in stable as rigid networks between atoms, and why molecules can change into different types of molecules. The most important event for solving the puzzles is the discovery of the quantum mechanics. Quantum mechanics is the theory for small particles such as electrons and nuclei, and was applied to hydrogen molecule by Heitler and London at 1927.

  • 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.

  • The story of metal casting is as glamorous as it is ancient, beginning with the dawn of human civilization and interwoven with legends of fantastic weapons and exquisite artworks made of precious metals. It was and is involved in the two main activities of humans since they began walking the earth: producing and defending wealth. Civilization as we know it would not have been possible without metal casting. Metal casting must have emerged from the darkness of antiquity first as magic, later to evolve as an art, then as a technology, and finally as a complex, interdisciplinary science....

  • This is believed to be the first book that takes a view of nanotechnology from a telecommunications and networking perspective. Nanotechnology refers to the manipulation of materials at the atomic or molecular level. Nanotechnology is getting a lot of attention of late not only in academic settings and in laboratories around the world, but also in government and venture capitalists’ initiatives. There now is a major drive to commercialize the technology by all sorts of firms, ranging from startups to Fortune 100 companies.

  • As quantum theory enters its second century, it is fitting to examine just how far it has come as a tool for the chemist. Beginning with Max Planck’s agonizing conclusion in 1900 that linked energy emission in discreet bundles to the resultant black-body radiation curve, a body of knowledge has developed with profound consequences in our ability to understand nature. In the early years, quantum theory was the providence of physicists and certain breeds of physical chemists. While physicists honed and refined the theory and studied...

  • The technique now known as MS has its roots in atomic physics at the beginning of the twentieth century, when it was originally applied by physicists toward answering questions on the nature of atoms. Throughout much of the 1800s, the prevailing wisdom held that atoms were indivisible, that all atoms of a given element had the same mass, and that the masses of all elements were multiples of the mass of hydrogen [7–9].

  • Th ere is something about being human that instills in us a sense of wonder. When we stop to think about it, the very idea of life seems such a mystery. Where did we come from? How did life begin? When we look at the sky, we wonder about the vastness of the universe and whether other life may exist there. If we look through a microscope at a drop of pond water, we are amazed at the variety of tiny creatures we see. Since cells form the very basis of life, it is only natural that our sense of wonder extends to the cell. Where did...

  • This book has evolved from over a quarter-century of research that concentrated on delineating the aqueous coordination reactions that characterize the vanadium(V) oxidation state. At the beginning of this time period, only a minor amount of research was being done on vanadium aqueous chemistry. However, the basic tenets of 51 V NMR spectroscopy were being elaborated, and some of the influences of ligand properties and coordination geometry on the NMR spectra were being ascertained.

  • Titrimetry refers to that group of analytical techniques which takes advantage of titers or concentrations of solutions. The word "titer" is also used to denote "equivalence" or that amount of a solution required to complete a chemical reaction. Titrimetry often refers to the use of some volume of a solution of known concentration to determine the quantity of an analyte. But there are some variations on the use of the term.
