Standard X-Ray Diffraction Powder Patterns
NBS MONOGRAPH 25 — SECTION 1 Standard X-ray Diffraction U.S. DEPARTMENT OF COMMERCE NATIONAL BUREAU OF STANDARDS THE NATIONAL BUREAU OF STANDARDS Functions and Activities The functions of the National Bureau of Standards are set forth in the Act of Congress, March 3, 1901, as amended by Congress in Public Law 619, 1950. These include the development and maintenance of the national standards of measurement and the provision of means and methods for making measurements consistent with these standards; the determination of physical constants and properties of materials; the development of methods and instruments for testing materials, devices, and structures; advisory services to government agencies on scien- tific and technical problems; invention and development of devices to serve special needs of the Government; and the development of standard practices, codes, and specifications. The work includes basic and applied research, development, engineering, instrumentation, testing, evaluation, calibration services, and various consultation and information services. Research projects are also performed for other government agencies when the work relates to and supplements the basic program of the Bureau or when the Bureau's unique competence is required. The scope of activities is suggested by the listing of divisions and sections on the inside of the back cover. Publications The results of the Bureau's research are published either in the Bureau's own series of publications or in the journals of professional and scientific societies. The Bureau itself publishes three periodicals available from the Government Printing Office: The Journal of Research, published in four separate sections, presents complete scientific and technical papers; the Technical News Bulletin presents summary and preliminary reports on work in progress; and Basic Radio Propagation Predictions provides data for determining the best frequencies to use for radio communications throughout the world. -

NMR Investigations of Crystalline and Glassy Solid Electrolytes for Lithium Batteries: a Brief Review
International Journal of Molecular Sciences Review NMR Investigations of Crystalline and Glassy Solid Electrolytes for Lithium Batteries: A Brief Review Daniel J. Morales 1,2 and Steven Greenbaum 1,* 1 Department of Physics and Astronomy, Hunter College of the City University of New York, New York, NY 10065, USA; [email protected] 2 Ph.D. Program in Physics, CUNY Graduate Center, New York, NY 10036, USA * Correspondence: [email protected] Received: 9 April 2020; Accepted: 28 April 2020; Published: 11 May 2020 Abstract: The widespread use of energy storage for commercial products and services have led to great advancements in the field of lithium-based battery research. In particular, solid state lithium batteries show great promise for future commercial use, as solid electrolytes safely allow for the use of lithium-metal anodes, which can significantly increase the total energy density. Of the solid electrolytes, inorganic glass-ceramics and Li-based garnet electrolytes have received much attention in the past few years due to the high ionic conductivity achieved compared to polymer-based electrolytes. This review covers recent work on novel glassy and crystalline electrolyte materials, with a particular focus on the use of solid-state nuclear magnetic resonance spectroscopy for structural characterization and transport measurements. Keywords: NMR; inorganic electrolytes; glassy electrolytes; ceramic electrolytes 1. Introduction As lithium ion batteries continue to permeate the commercial market, the search continues to produce an all solid-state equivalent with the same or superior performance. While liquid organic electrolytes continue to exhibit high performance and long cyclability, the risk of thermal runaway and inability to utilize Li metal anodes without the risk of dendrite formation are ongoing issues. -
Shortage of Germanium-68/Gallium-68 Generators for the Production of Gallium-68
August 6, 2018 US Food and Drug Administration 10903 New Hampshire Avenue Silver Spring, MD 20993 Re: Shortage of Germanium-68/Gallium-68 Generators for the Production of Gallium-68 Dear Dr. Marzella and Dr. Zadecky, The Society of Nuclear Medicine and Molecular Imaging (SNMMI) would like to provide the following information related to availability of GMP-grade germanium-68/gallium-68 generators in the United States. SNMMI, composed of 15,000 members, works to set standards for molecular imaging and nuclear medicine practice by creating guidelines, sharing information through journals, hosting meetings, and leading advocacy on key issues that affect molecular imaging and therapy research and practice. Germanium-68/Gallium-68 generators (68Ge/68Ga) Gallium-68 is currently milked from a 68Ge/68Ga generator. Several manufacturers produce these table top generators including Eckert & Ziegler (Germany), IRE ELiT (Belgium), Isotopen Technologien Munchen (ITG) (Germany), and iThemba (South Africa). The Eckert & Ziegler GalliaPharm® and the IRE ELiT Galli Eo® generators are both GMP grade and have type II drug master files on file with FDA. Use of Gallium-68 (68Ga) in the U.S. The radioisotope 68Ga is used in the production of NETSPOTTM, a kit for the preparation of gallium 68Ga dotatate injection, an FDA-approved radiopharmaceutical. NETSPOT was approved in June 2016 for localization of somatostatin receptor positive neuroendocrine tumors (NETs) in adult and pediatric patients using Positron Emission Tomography (PET). NETSPOT is currently approved for use only with the GalliaPharm 68Ga generator from Eckert & Ziegler. NETSPOT has experienced rapid adoption in the US. Advanced Accelerator Applications (AAA) has been expanding the network of pharmacies that distribute NETSPOT since its approval. -

Of the Periodic Table
of the Periodic Table teacher notes Give your students a visual introduction to the families of the periodic table! This product includes eight mini- posters, one for each of the element families on the main group of the periodic table: Alkali Metals, Alkaline Earth Metals, Boron/Aluminum Group (Icosagens), Carbon Group (Crystallogens), Nitrogen Group (Pnictogens), Oxygen Group (Chalcogens), Halogens, and Noble Gases. The mini-posters give overview information about the family as well as a visual of where on the periodic table the family is located and a diagram of an atom of that family highlighting the number of valence electrons. Also included is the student packet, which is broken into the eight families and asks for specific information that students will find on the mini-posters. The students are also directed to color each family with a specific color on the blank graphic organizer at the end of their packet and they go to the fantastic interactive table at www.periodictable.com to learn even more about the elements in each family. Furthermore, there is a section for students to conduct their own research on the element of hydrogen, which does not belong to a family. When I use this activity, I print two of each mini-poster in color (pages 8 through 15 of this file), laminate them, and lay them on a big table. I have students work in partners to read about each family, one at a time, and complete that section of the student packet (pages 16 through 21 of this file). When they finish, they bring the mini-poster back to the table for another group to use. -

Academic Editor: Alessandro Lavacchi Received: 23 December 2014 / Accepted: 9 March 2015 / Published: 13 March 2015 Abstract: In this work, a morphological and structural characterization of a ternary Ag-Cu-Ge alloy of known composition was performed with the aim of evaluating how the passivation parameters (time and temperature) influence the morphological features of the material surface. A nanomechanical characterization was performed in order to correlate the morphology and microstructure of the alloy with its tarnish, wear, and scratch resistance. It was found that the addition of germanium to the alloy not only provides the material with tarnish and fire-stain resistance, but it also improves the scratch and wear resistance owing to the formation of a dense and stable thin oxide layer. -
