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.

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: 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.

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.

Download or read book The Quartz Crystal Microbalance in Soft Matter Research written by Diethelm Johannsmann and published by Springer. This book was released on 2014-07-17 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the physics of the second-generation quartz crystal microbalance (QCM), a fundamental method of analysis for soft matter at interfaces. From a device for measuring film thickness in vacuum, the quartz crystal microbalance (QCM) has in the past two decades evolved into a versatile instrument for analyzing soft matter at solid/liquid and solid/gas interfaces that found applications in diverse fields including the life sciences, material science, polymer research and electrochemistry. As a consequence of this success, the QCM is now being used by scientists with a wide variety of backgrounds to study an impressive diversity of samples, with intricate data analysis methods being elaborated along the way. It is for these practitioners of the QCM that the book is written. It brings across basic principles behind the technique and the data analysis methods in sufficient detail to be educational and in a format that is accessible to anyone with an undergraduate level knowledge of any of the physical or natural sciences. These principles concern the analysis of acoustic shear waves and build on a number of fundamental physical concepts which many users of the technique do not usually come across. They have counterparts in optical spectroscopy, electrical engineering, quantum mechanics, rheology and mechanics, making this book a useful educational resource beyond the QCM itself. The main focus is the physics of QCM, but as the book describes the behavior of the QCM when exposed to films, droplets, polymer brushes, particles, vesicles, nanobubbles and stick-slip, it also offers insight into the behavior of soft matter at interfaces in a more general sense.
