Download or read book Microweighing in Vacuum and Controlled Environments written by A.W. Czanderna and published by Elsevier. This book was released on 2012-12-02 with total page 419 pages. 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.

Available in PDF, EPUB and Kindle. Book excerpt: viii The danger is that the result so obtained may be an experimental artifact. Another approach is to examine in as much detail as possible the principles underlying the operation of a new device. This may not lead to a new sensor immediately, but those developed along these lines tend to be more reliable. The accent in this book is therefore on the principles behind the operation ("the trade") rather than on a description of applications ("the tricks of the trade") of individual sensors. In this respect it is written for students at both graduate and upper undergraduate levels. Approximately one semester's worth of material is presented. The book may also be useful for scientists and engineers involved in the development of new types of chemical sensors or for those who discover that "somebody else's sensor just does not work as it should" and wish to know why. The book is divided into five sections dealing with the four principal modes of transduction: thermal, mass, electrochemical, and optical, as well as a general introduction common to the four types. I have included five appendixes, which are intended as a quick reference for readers who may not possess sufficient background in some areas covered in the main text. I have run out of symbols in both the Latin and Greek alphabets. In order to avoid confusion and ambiguity I have confined the use of a set of symbols to each chapter and provided glossaries at the end of each chapter.
Download or read book Applications of Piezoelectric Quartz Crystal Microbalances written by C. Lu and published by Elsevier. This book was released on 2012-12-02 with total page 408 pages. 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 Advances in Instrumentation written by WIEDEMANN and published by Birkhäuser. This book was released on 2013-06-29 with total page 620 pages. Available in PDF, EPUB and Kindle. Book excerpt: Earlier efforts in the field of thermal analysis were concerned with the demonstration of the applicability of techniques to a broad spectrum of materials and to establish the relationship of such techniques with other more accepted methods. While such efforts will and should continue, the Third International Conference was unique in that the first standards were disclosed for differential thermal analysis. This was the culmination of the international, cooperative effort of the ICTA's Standardization Committee. The standards currently are available from the United State's National Bureau of Standards. Thus, thermal analysis can be considered to have attained its majority. Reali zation of full maturity can be expected in the near future. Inclusion of plenary lectures in these volumes represents a significant departure from previous Conferences. This change is the result of the ICTA's recognition of its educational responsibilities. In the Foreword of the Proceedings of the Second International Confer ence, Professor L. Berg expressed the hope that thermal methods of analysis would find wider application in science and technology. The citation above, together with the papers presented, indicate the fulfillment of this hope. Xerox Corporation C. B. Murphy Rochester, N.Y., U.S.A. President, ICTA 1968-1971 X Ill PREFACE For the past two decades thermoanalytical methods have reached a stage of considerable importance, which is particularly due to the developments in the area of instrumentation.
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: This volume contains the proceedings of the Eighth Conference on Vacuum Microbalance Techniques held at Wakefield, Massachusetts on June 12 and 13, 1969. The tenth anniversary of the first confer ence will be registered as this volume passes through the typeset ting and proofreading stages. The eight volumes that have spawned from this continuing series of conferences now contain a total of 125 papers. Thus, these volumes serve as a major repository of the world's literature on vacuum microbalance techniques. The Ninth and Tenth Conferences will be held in West Germany in June 1970 and in Texas in 1971. Each of the eight meetings has served as a forum where new developments in this rapidly advancing field can be presented and discussed constructively within a conference atmosphere of cordial informality. The interaction of the participants at the conferences has led to the first treatise on ultra mlcrogravtmetry;' edited by S. P. Wolsky and E. J. Zdanuk, with most of the fourteen chapters written by steady contributors to the volumes on Vacuum Micro balance Techniques. The number of research investigations and published works in which a vacuum microbalance is utilized con tinues to expandr apldly. f This is a direct result of several types of automatic recording balances that are now available commercial ly. 3 The Eighth Conference was held to bring together again re search scientists and engineers who exploit the measurement of mass as a means of studying physical and chemical phenomena.

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.
