Available in PDF, EPUB and Kindle. Book excerpt: Methods and Phenomena, 4: Their Applications in Science and Technology: Microweighing in Vacuum and Controlled Environments focuses on the principles, methodologies, and approaches involved in micro mass measurements. The selection first elaborates on introduction and microbalance review, beam microbalance design, construction and operation, and sources of error in microweighing in controlled environments. Discussions focus on Brownian motion, Knudsen forces, gravitational forces, microbalance construction and operation, auxiliary equipment for operation of a vacuum microbalance, undesirable disturbances or forces, calibration techniques, and classification of various types of microbalances. The text then takes a look at physical adsorption studies and chemisorption studies with the vacuum microbalance, simultaneous microgravimetric and residual gas analyzer measurements, and simultaneous measurement of mass change and infrared spectra. Topics include chemisorption results obtained on other solids and silver powders, probing the surface phase, quantitative information from adsorption and desorption, measuring techniques, and examples of physisorption measurements and their evaluation. The manuscript examines unusual applications of the vacuum microbalance and high temperature reaction studies, as well as empirical and theoretical rate laws, permeation of water vapor through plastic membranes, and measurement of permittivity and dielectric loss factor. The selection is a valuable source of data for researchers wanting to explore microweighing in vacuum and controlled environments.

Download or read book Balances written by Erich Robens and published by Springer Science & Business Media. This book was released on 2013-10-01 with total page 743 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book deals mainly with direct mass determination by means of a conventional balances. It covers the history of the balance from the beginnings in Egypt earlier than 3000 BC to recent developments. All balance types are described with emphasis on scientific balances. Methods of indirect mass determination, which are applied to very light objects like molecules and the basic particles of matter and celestial bodies, are included. As additional guidance, today’s manufacturers are listed and the profile of important companies is reviewed. Several hundred photographs, reproductions and drawings show instruments and their uses. This book includes commercial weighing instruments for merchandise and raw materials in workshops as well as symbolic weighing in the ancient Egyptian’s ceremony of ‘Weighing of the Heart’, the Greek fate balance, the Roman Justitia, Juno Moneta and Middle Ages scenes of the Last Judgement with Jesus or St. Michael and of modern balances. The photographs are selected from the slide-archives of the late Richard Vieweg (1896-1972) (former President of the Physikalisch-Technische Bundesanstalt, Braunschweig, Germany), of the late Hans R. Jenemann (1920-1966) (former head of the Analytical Laboratory of Schott & Gen., Mainz, Germany) and of his wife Irene (1933-2008) and of Erich Robens.

Available in PDF, EPUB and Kindle. Book excerpt: Applications of Piezoelectric Quartz Crystal Microbalances deals with the theory, design, artifacts, and varied applications of the piezoelectric quartz crystal microbalance. Applications of microbalances range from thin film deposition process control to simultaneous measurement of mass and temperature, analytical chemistry, and space system contamination studies. Stress effects in microbalances are also considered. Comprised of 10 chapters, this volume begins with a historical background and overview of applications of piezoelectric quartz crystal microbalances, followed by an analysis of the theory and practice of microbalances. The role of acoustic impedance in a quartz crystal microbalance and design considerations for a microbalance are given emphasis. Subsequent chapters focus on applications of microbalances in thin film deposition process control; simultaneous measurement of mass and temperature; surface science and analytical chemistry; plasma-assisted etching and space system contamination studies; and aerosol mass measurement. This monograph will be of interest to students and practitioners of physics, chemistry, and materials science.

Download or read book Catalyst Characterization written by Boris Imelik and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 720 pages. Available in PDF, EPUB and Kindle. Book excerpt: to the Fundamental and Applied Catalysis Series Catalysis is important academically and industrially. It plays an essential role in the manufacture of a wide range of products, from gasoline and plastics to fertilizers and herbicides, which would otherwise be unobtainable or prohibitive ly expensive. There are few chemical-or oil-based material items in modern society that do not depend in some way on a catalytic stage in their manufacture. Apart from manufacturing processes, catalysis is finding other important and over-increasing uses; for example, successful applications of catalysis in the control ofpollution and its use in environmental control are certain to in crease in the future. The commercial import an ce of catalysis and the diverse intellectual challenges of catalytic phenomena have stimulated study by a broad spectrum of scientists including chemists, physicists, chemical engineers, and material scientists. Increasing research activity over the years has brought deeper levels of understanding, and these have been associated with a continually growing amount of published material. As recentlyas sixty years ago, Rideal and Taylor could still treat the subject comprehensively in a single volume, but by the 19 50s Emmett required six volumes, and no conventional multivolume text could now cover the whole of catalysis in any depth.

Download or read book Colloid Science written by Douglas H Everett and published by Royal Society of Chemistry. This book was released on 2007-10-31 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: Specialist Periodical Reports provide systematic and detailed review coverage of progress in the major areas of chemical research. Written by experts in their specialist fields the series creates a unique service for the active research chemist, supplying regular critical in-depth accounts of progress in particular areas of chemistry. For over 80 years the Royal Society of Chemistry and its predecessor, the Chemical Society, have been publishing reports charting developments in chemistry, which originally took the form of Annual Reports. However, by 1967 the whole spectrum of chemistry could no longer be contained within one volume and the series Specialist Periodical Reports was born. The Annual Reports themselves still existed but were divided into two, and subsequently three, volumes covering Inorganic, Organic and Physical Chemistry. For more general coverage of the highlights in chemistry they remain a 'must'. Since that time the SPR series has altered according to the fluctuating degree of activity in various fields of chemistry. Some titles have remained unchanged, while others have altered their emphasis along with their titles; some have been combined under a new name whereas others have had to be discontinued.

Book excerpt: Water Relations of Foods consists of proceedings of an international symposium on "Water Relations of Foods held in Glasgow, in September 1974. Organized into seven sections, the book presents the various papers delivered in the symposium. It describes the physical chemistry of water in simple systems as well as in the more complex food component systems (carbohydrates, lipids, and proteins), with emphasis on the nature of the intermolecular forces involved. It also reports the various techniques used to measure the state of water in food and in model systems made up of food components. Furthermore, the book discusses water activity and the growth of food spoilage and pathogenic organism; water relations of enzymic and non-enzymic deteriorative reactions in food; effects of freezing and thawing of water in food systems; and the significant aspects of food quality as affected by water in the system. Lastly, the modification of the state of water in foods is addressed. This publication will indeed help advance the understanding on this field of interest.

This book was released on 2013-06-29 with total page 195 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last several years, the field of materials science has witnessed an explosion of new, advanced materials. They encompass many uses and include superconductors, alloys, glasses, and catalysts. Not only are there quite a number of new enhies into these generic classes of materials, but the materials themselves represent a wide array of physical forms as well. Bulk materials, for example, are being synthesized and applica tions found for them, while still other materials are being synthesized as thin films for yet still more new (and in some cases, as yet unknown) applications. The field continues to expand with (thankfully!) no end in sight as to the number of new possibilities. As work progresses in this area, there is an ever increasing demand for knowing not only what material is formed as an end product but also details of the route by which it is made. The knowledge of reaction mechanisms in their synthesis many times allows a researcher to tailor a preparative scheme to either arrive at the final product in a purer state or with a better yield. Also, a good fundamental experimental knowledge of impuri ties present in the final material helps the investigator get more insight into making it.
