Book excerpt: Reaction studies have been carried out on the destruction of nitrogen-containing compounds such as ammonium, nitrates, and species containing aromatic nitro functionality. The destruction of ammonium ion in near-critical and supercritical water using Raman spectroscopy is the subject of this presentation. Reaction rates were determined from Raman spectra and from measurements of system pressure. Concentrations of key species in the reactor effluent were determined via off-line assay. The effects of temperature, pressure, and concomitants on reaction rate were determined. The reaction half-life is below ten seconds at 400 C with better than 95% conversion. Oxides of nitrogen were not generated in detectable quantities. The studied system is a model for the destruction of ammonium in municipal wastes.

Book excerpt: The present understanding of high-pressure/high-temperature dense-fluid behavior is derived almost exclusively from hydrodynamic and thermodynamic measurements. Such results average over the microscopic aspects of the materials and are, therefore, insufficient for a complete understanding of fluid behavior. At the present, dense-fluid models can be verified only to the extend that they agree with the macroscopic measurements. Recently, using stimulated Raman scattering, Raman induced Kerr effect scattering, and coherent anti-Stokes Raman scattering, we have been able to probe some of the microscopic phenomenology of these dense fluids. In this paper, we discuss primarily the use of CARS in conjunction with a two-stage light-gas gun to obtain vibrational spectra of shock-compressed liquid N2, O2, CO, their mixtures, CH3NO2, and N2O. These experimental spectra are compared to synthetic spectra calculated using a semiclassical model for CARS intensities and best fit vibrational frequencies, peak Raman susceptibilities, and Raman linewidths. For O2, the possibility of resonance enhancement from collision-induced absorption is addressed. Shifts in the vibrational frequencies reflect the influence of increased density and temperature on the intramolecular motion. The derived parameters suggest thermal equilibrium of the vibrational levels is established less than a few nanoseconds after shock passage. Vibrational temperatures are obtained that agree with those derived from equation-of-state calculations. Measured linewidths suggest that vibrational dephasing times have decreased to subpicosecond values at the highest shock pressures.

Available in PDF, EPUB and Kindle. Book excerpt: A practical guide to the methods in general use for the complete analysis of silicate rock material and for the determination of all those elements present in major, minor or trace amounts in silicate and other rocks that are routinely, commonly or occasionally determined by methods that are considered to be essentially chemical in character. Such methods include those based upon spectrophotometry, flame emission spectrometry and atomic absorption spectroscopy, as well as gravimetry, titrimetry and the use of ion-selective electrodes. Separation stages are described in full, using precipitation, solvent extraction, distillation, and ion-ex procedures as appropriate. The third edition has been fully revised and updated.

Download or read book A Century of Excellence in Measurements Standards and Technology written by David R. Lide and published by CRC Press. This book was released on 2001-10-30 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: Established by Congress in 1901, the National Bureau of Standards (NBS), now the National Institute of Standards and Technology (NIST), has a long and distinguished history as the custodian and disseminator of the United States' standards of physical measurement. Having reached its centennial anniversary, the NBS/NIST reflects on and celebrates its first century with this book describing some of its seminal contributions to science and technology. Within these pages are 102 vignettes that describe some of the Institute's classic publications. Each vignette relates the context in which the publication appeared, its impact on science, technology, and the general public, and brief details about the lives and work of the authors. The groundbreaking works depicted include: A breakthrough paper on laser-cooling of atoms below the Doppler limit, which led to the award of the 1997 Nobel Prize for Physics to William D. Phillips The official report on the development of the radio proximity fuse, one of the most important new weapons of World War II The 1932 paper reporting the discovery of deuterium in experiments that led to Harold Urey's1934 Nobel Prize for Chemistry A review of the development of the SEAC, the first digital computer to employ stored programs and the first to process images in digital form The first paper demonstrating that parity is not conserved in nuclear physics, a result that shattered a fundamental concept of theoretical physics and led to a Nobel Prize for T.

Book excerpt: New Generation Green Solvents for Separation and Preconcentration of Organic and Inorganic Species is designed to help researchers and students understand the production and application of new generation green solvents in separation- and preconcentration-based analytical methods. Beginning with the historical background and milestones in the development of analytical instrumentation, the book goes on to give a detailed overview of the most up-to-date uses of green solvents in sample preparation. Using a wealth of examples, it compares old and new extraction procedures and explores the many applications of new generation green solvents. Practical, easy-to-follow experiments are used to illustrate the key concepts. This practical guide helps to promote the use of safer, more sustainable solvents in analytical chemistry and beyond for environmental scientists, researchers in pharmaceutical and biotech industries, and students in analytical chemistry. Covers the basic analytical theory essential for understanding extraction- and microextraction-based separation and preconcentration methods Explains combination use of new generation solvents with various detection systems, including UV-VIS, ICP-MS, HPLC, LC-MS, GC-MS, and LC-MS/MS Emphasizes trace chemical component separation, preconcentration and analysis
