The Bureau's overall goal is to strengthen and advance the Nation's science and technology and facilitate their effective application for public benefit. To this end, the Bureau conducts research and provides: (1) a basis for the Nation's physical measurement system, (2) scientific and technological services for industry and government, (3) a technical basis for equity in trade, and (4) technical services to promote public safety. The Bureau's technical work is per- formed by the National Measurement Laboratory, the National Engineering Laboratory, and the Institute for Computer Sciences and Technology. THE NATIONAL MEASUREMENT LABORATORY provides the national system of physical and chemical and materials measurement; coordinates the system with measurement systems of other nations and furnishes essential services leading to accurate and uniform physical and chemical measurement throughout the Nation's scientific community, industry, and commerce; conducts materials research leading to improved methods of measurement, standards, and data on the properties of materials needed by industry, commerce, educational institutions, and Government; provides advisory and research services to other Government agencies; develops, produces, and distributes Standard Reference Materials; and provides calibration services. The Laboratory consists of the following centers: Absolute Physical Quantities^ — Radiation Research — Chemical Physics — Analytical Chemistry — Materials Science THE NATIONAL ENGINEERING LABORATORY provides technology and technical ser- vices to the public and private sectors to address national needs and to solve national problems; conducts research in engineering and applied science in support of these efforts; builds and maintains competence in the necessary disciplines required to carry out this research and technical service; develops engineering data and measurement capabilities; provides engineering measurement traceability services; develops test methods and proposes engineering standards and code changes; develops and proposes new engineering practices; and develops and improves mechanisms to transfer results of its research to the ultimate user. The Laboratory consists of the following centers: Applied Mathematics — Electronics and Electrical Engineering^ — Manufacturing Engineering — Building Technology — Fire Research — Chemical Engineering^ THE INSTITUTE FOR COMPUTER SCIENCES AND TECHNOLOGY conducts research and provides scientific and technical services to aid Federal agencies in the selection, acquisition, application, and use of computer technology to improve effectiveness and economy in Government operations in accordance with Public Law 89-306 (40 U.S.C. 759), relevant Executive Orders, and other directives; carries out this mission by managing the Federal Information Processing Standards Program, developing Federal ADP standards guidelines, and managing Federal participation in ADP voluntary standardization activities; provides scientific and technological advisory services and assistance to Federal agencies; and provides the technical foundation for computer-related policies of the Federal Government. The Institute consists of the following centers: Programming Science and Technology — Computer Systems Engineering.

Hammond. Norris Award lecture, 1968 SUMMARY Developing new technological solutions, such as use of lightweight materials, less harmful fuels, controlled fuel combustion processes or more efficient exhaust gas after-treatment, are possible ways to reduce the environmental impact of machines. Both the reduction of wear and the friction control are key issues for decreasing of energy losses, improving efficiency and increasing of the life-span of an engine. Dialkyldithiophosphates (DTPs) of different metals have been extensively used as multifunctional additives in lubricants to control friction and reduce wear in mechanical systems. Among these DTP-compounds, zinc dialkyldithiophosphates (ZnDTPs) are the most common additives used for more than 60 years. These additives form protective films on steel surfaces and, thus, control friction and reduce wear.

Algorithms to determine coordination num- bers automatically are increasingly used for machine learning and automatic structural analysis. In this work, we introduce MaterialsCoord, a benchmark suite containing 56 experimentally-derived crystal structures (spanning elements, binaries, and ternary compounds) and their corresponding coordination environments as described in the research literature. We also describe CrystalNN, a novel algorithm for determining near neighbors. We compare CrystalNN against 7 existing near-neighbor algorithms on the MaterialsCoord benchmark, finding CrystalNN to perform similarly to several well-established algorithms. For each algorithm, we also assess computational demand and sensitivity towards small perturbations that mimic thermal motion. Finally, we 1 investigate the similarity between bonding algorithms when applied to the Materials Project database.

    Lithium Titanate Hydrates with Superfast and Stable Cycling in Lithium Ion Batteries

    ARTICLE DOI: 10.1038/s41467-017-00574-9 OPEN Lithium titanate hydrates with superfast and stable cycling in lithium ion batteries Shitong Wang1,2, Wei Quan1, Zhi Zhu2, Yong Yang3, Qi Liu4, Yang Ren4, Xiaoyi Zhang4, Rui Xu5, Ye Hong1, Zhongtai Zhang1, Khalil Amine5, Zilong Tang1, Jun Lu 5 &JuLi 2,6 Lithium titanate and titanium dioxide are two best-known high-performance electrodes that can cycle around 10,000 times in aprotic lithium ion electrolytes. Here we show there exists more lithium titanate hydrates with superfast and stable cycling. That is, water promotes structural diversity and nanostructuring of compounds, but does not necessarily degrade electrochemical cycling stability or performance in aprotic electrolytes. As a lithium ion battery anode, our multi-phase lithium titanate hydrates show a specific capacity of about 130 mA h g−1 at ~35 C (fully charged within ~100 s) and sustain more than 10,000 cycles with capacity fade of only 0.001% per cycle. In situ synchrotron diffraction reveals no 2-phase transformations, but a single solid-solution behavior during battery cycling. So instead of just a nanostructured intermediate to be calcined, lithium titanate hydrates can be the desirable final destination. 1 State Key Lab of New Ceramics and Fine Processing, School of Materials Science and Engineering, Tsinghua University, Beijing 100084, China. 2 Department of Nuclear Science and Engineering, Massachusetts Institute of Technology, Cambridge, Massachusetts 02139, USA. 3 Department of Chemistry, Tsinghua University, Beijing 100084, China. 4 X-ray Science Division, Advanced Photon Source, Argonne National Laboratory, Lemont, Illinois 60439, USA. 5 Chemical Sciences and Engineering Division, Argonne National Laboratory, Lemont, Illinois 60439, USA.

    Exemption for the Use of Cadmium in Portable Batteries and Accumulators

    Exemption for the use of cadmium in portable batteries and accumulators intended for the use in cordless power tools in the context of the Batteries Directive 2006/66/EC Final Report (revised) 26 January 2010 Consortium ESWI Expert TeamBIPRO, to S upportUmweltbundesamt Waste Implementation BiPRO Beratungsgesellschaft für integrierte Problemlösungen ENV.G.4/FRA/2007/0066 iii European Commission ESWI Final Report - Replacement of Cadmium Batteries in Cordless Power Tools ENV.G.4/FRA/2007/0066 iv Executive Summary Background The Batteries Directive 2006/66/EC (repealing Directive 91/157/EEC) entered into force on 26 September 20061. The Directive sets out rules applicable to all batteries and accumulators that are put on the European Union market. These rules include, among others, restriction on the use of cadmium in portable batteries and accumulators (PBA) according to Article 4(1)(b) of the Directive. Portable batteries and accumulators, including those incorporated into appliances, that contain more than 0,002% of cadmium by weight shall not be placed on the market. However, according to Article 4(3) of the Directive the above requirement shall not apply to portable batteries and accumulators intended for use in: (a) emergency and alarm systems, including emergency lighting; (b) medical equipment; or (c) cordless power tools. Furthermore, based on Article 4(4) of the Directive the Commission shall review the exemption from the cadmium ban for use in cordless power tool with a view to the prohibition of cadmium in batteries and accumulators. The Commission shall submit a corresponding report to the European Parliament and to the Council by 26 September 2010, together, if appropriate, with relevant proposals.
