Download or read book New Frontiers for Metrology From Biology and Chemistry to Quantum and Data Science written by M.J.T. Milton and published by IOS Press. This book was released on 2021-12-22 with total page 480 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of standard and reliable measurements is essential in many areas of life, but nowhere is it of more crucial importance than in the world of science, and physics in particular. This book contains 20 contributions presented as part of Course 206 of the International School of Physics Enrico Fermi on New Frontiers for Metrology: From Biology and Chemistry to Quantum and Data Science, held in Varenna, Italy, from 4 -13 July 2019. The Course was the 7th in the Enrico Fermi series devoted to metrology, and followed a milestone in the history of measurement: the adoption of new definitions for the base units of the SI. During the Course, participants reviewed the decision and discussed how the new foundation for metrology is opening new possibilities for physics, with several of the lecturers reflecting on the implications for an easier exploration of the unification of quantum mechanics and gravity. A wide range of other topics were covered, from measuring color and appearance to atomic weights and radiation, and including the application of metrological principles to the management and interpretation of very large sets of scientific data and the application of metrology to biology. The book also contains a selection of posters from the best of those presented by students at the Course. Offering a fascinating exploration of the latest thinking on the subject of metrology, this book will be of interest to researchers and practitioners from many fields.

Download or read book The Characterization of Chemical Purity written by L. A. K. Staveley and published by Elsevier. This book was released on 2016-03-05 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Characterization of Chemical Purity: Organic Compounds focuses on the processes, methodologies, and reactions involved in chemical purity. The selection first offers information on the concept of purity and its bearing on methods used to characterize purity and thermal methods, including general observations on impurity determination, freezing and melting phenomena, and classification of thermal methods of purity control. The manuscript also takes a look at density measurements, refractive index, and vapor pressure and boiling temperature measurements. The book ponders on chromatography and mass spectrometry. Discussions focus on chromatograms, testing of purity, quantitative and qualitative analysis, and liquid chromatography. The text also reviews optical, Raman, and nuclear magnetic resonance spectroscopy. Topics include infra-red (vibrational) spectra, experimental techniques, and nature of the Raman effect. Chemical and physical measurements, calibration of instruments, availability of standard reference materials, and value of human effort are discussed. The manuscript is a dependable reference for readers interested in chemical purity.

Download or read book Proposed Amendments to the Toxic Substances Control Act TSCA written by Linda-Jo Schierow and published by DIANE Publishing. This book was released on 2011-05 with total page 69 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Spring 2010, a Senate bill and a House bill were introduced to amend TSCA. This report compares both bills, and current law. Both bills would amend the 35-year-old law to shift the burden of demonstrating safety for chemicals in commerce from the EPA to manufacturers and processors of chemicals. Both bills also would prohibit manufacture, processing, and dist. of any chemical substance for which safety has not been demonstrated. Both bills suggest a health-based standard. In contrast, current law requires that a chemical not pose ¿an unreasonable risk of injury to health or the environ.,¿ and that any reg¿n. should control unreasonable risk to the extent necessary using the ¿least burdensome¿ means of control.
