Chemical Innovation Technologies to Make Processes and Products More Sustainable
United States Government Accountability Office Center for Science, Technology, and Engineering Natural Resources and Environment Report to Congressional Requesters February 2018 TECHNOLOGY ASSESSMENT Chemical Innovation Technologies to Make Processes and Products More Sustainable GAO-18-307 The cover image displays a word cloud generated from the transcript of the meeting we convened with 24 experts in the field of sustainable chemistry. The size of the words in the cloud corresponds to the frequency with which each word appeared in the transcript. In most cases, similar words—such as singular and plural versions of the same word— were combined into a single term. Words that were unrelated to the topic of sustainable chemistry were removed. The images around the periphery are stylized representations of chemical molecules that seek to illustrate a new conceptual framework, whereby molecules can be transformed to provide better performance; however, they are not intended to represent specific chemical compounds.

Sodium Azide [Sep-100] for Control of Nematodes and Weed Problems in Green Pepper Production R
SODIUM AZIDE [SEP-100] FOR CONTROL OF NEMATODES AND WEED PROBLEMS IN GREEN PEPPER PRODUCTION R. Rodriguez-Kabana and J. R. Akridge, Auburn University and Alabama Agricultural Experiment Station Auburn, Alabama 36830, U.S.A. [email protected] ABSTRACT The efficacy of SEP-100, a liquid formulation of Na azide, as an alternative for methyl bromide (MB) in soil fumigation was studied in field experiments with ‘Aladdin’ green pepper [Capsicum annum]. Pre-plant applications of SEP-100 by drip irrigation to plastic covered beds at rates of 50, 75, 100, 125, 150, 175, and 200 lbs.a.i./A, were effective in controlling root-knot nematode (Meloidogyne incognita), purple nutsedge (Cyperus rotundus), and Panicum spp. Na azide rates > 100 lbs /A consistently equaled or outperformed MB (300 lbs/A) in controlling root-knot nematodes and weeds. Total marketable yields, and yields of Fancy, No. 1, and No. 2 peppers increased directly and linearly in relation to SEP 100 doses. MB fumigation resulted in increased marketable yield and increases in weights of all yield categories; however, these responses did not achieve the levels observed for SEP 100 rates > 125 lbs a.i./A. Results indicate that Na azide in the SEP-100 formulation is a practical and safe potential alternative to MB for soil fumigation in green pepper production. Key Words: azides, inorganic azides, herbicide, horticultural crops, hydrazoic acid, methyl bromide alternatives, nematicide, pest management, root-knot nematodes, soil-borne pests, soil fumigation, weed control. INTRODUCTION Green or bell peppers constitute over two-thirds of the total pepper production in North America (Sundstrom, 1992). -

However, synthesis and storage of such compounds remain a big challenge because of difficulties to find energy efficient synthetic routes and stabilization mechanisms. Compounds of metals with nitrogen represent promising candidates for realization of energetic polynitrogen compounds, which are also environmentally benign. Here we report the synthesis of polynitrogen planar N6 hexazine rings, stabilized in K2N6 compound, which was formed from K azide upon laser heating in a diamond anvil cell at high pressures in excess of 45 GPa and remains metastable down to 20 GPa. Synchrotron X-ray diffraction and Raman spectroscopy are used to identify this material, also exhibiting metallic luster, being all consistent with theoretically predicted structural, vibrational and electronic properties. The documented here N6 hexazine rings represent new highly energetic polynitrogens, which have a potential for future recovery and utilization. -

Banks Received: 6 February 2017; Accepted: 18 April 2017; Published: 29 April 2017 Abstract: Our study is the first attempt to study the interaction between NaN3 and hydrated fullerenes C60 by means of a non-chemical reaction-based approach. The aim is to study deviations of signals obtained by 14N NMR spectroscopy to detect the binding interaction between sodium azide and hydrated fullerene. We considered 14N NMR spectroscopy as one of the most suitable methods for the characterization of azides to show resonance signals corresponding to the three non-equivalent nitrogen atoms. The results demonstrate that there are changes in the chemical shift positions and line-broadening, which are related to the different molar ratios of NaN3:C60 in the samples. Keywords: sodium azide; fullerene; 14N NMR spectroscopy; nanofiltration 1. Introduction The presence of pharmaceutical active compounds (PhACs) in surface, drinking, and wastewaters is an emerging issue in environmental science [1–9]. Low levels of many pharmaceutical active compounds are detected in the aquatic environment as a result of pharmaco-chemical industrial waste spill-off in draining water. -

1.3 Communicating Safety Information Samuella Sigmann Visit the full ACS Guide to Scholarly Communication 1.3.1 Introduction In 2011, the U.S. Chemical Safety Board (CSB) issued its first investigation of a chemical accident at an academic research institution. The incident involved the sudden detonation of a nickel hydrazine perchlorate (NHP) derivative that resulted in severe and permanent injury to a fifth-year chemistry graduate student at Texas Tech University (TTU). Student researchers were involved in a multi-institutional research project to characterize new potentially energetic materials. They decided to scale up their synthesis by two orders of magnitude to provide enough sample so that all testing could be performed on one batch but neglected to assess safety ramifications. The final CSB report for the TTU incident found in both this case and prior incidents in the same research area that (1): . No formal hazard evaluation and risk assessment had been completed to char-acterize the potential danger of the research activity and to plan for the worst-case scenario. The student sought peer advice. No policy was in place at the laboratory, department, or university level to prompt a student to seek PI advice or evaluation of experimental activities. The investigation clearly indicates that the students did not have the information they needed to prepare themselves for the increased risk posed by their decision to scale up. The CSB primarily investigates and reports on large scale incidents in the chemical and related industries where hazard evaluation and risk assessment are well established to facilitate improved safety management across the industry. -

Route to High-Energy Density Polymeric Nitrogen T-N Via Heâˆ'n Compounds
ARTICLE DOI: 10.1038/s41467-018-03200-4 OPEN Route to high-energy density polymeric nitrogen t- N via He−N compounds Yinwei Li1, Xiaolei Feng2,3, Hanyu Liu4, Jian Hao1, Simon A.T. Redfern 3,5, Weiwei Lei6, Dan Liu6 & Yanming Ma2,7 Polymeric nitrogen, stabilized by compressing pure molecular nitrogen, has yet to be recovered to ambient conditions, precluding its application as a high-energy density material. 1234567890():,; Here we suggest a route for synthesis of a tetragonal polymeric nitrogen, denoted t-N, via He-N compounds at high pressures. Using first-principles calculations with structure searching, we predict a class of nitrides with stoichiometry HeN4 that are energetically stable (relative to a mixture of solid He and N2) above 8.5 GPa. At high pressure, HeN4 comprises a polymeric channel-like nitrogen framework filled with linearly arranged helium atoms. The nitrogen framework persists to ambient pressure on decompression after removal of helium, forming pure polymeric nitrogen, t-N. t-N is dynamically and mechanically stable at ambient pressure with an estimated energy density of ~11.31 kJ/g, marking it out as a remarkable high- energy density material. This expands the known polymeric forms of nitrogen and indicates a route to its synthesis. 1 School of Physics and Electronic Engineering, Jiangsu Normal University, Xuzhou 221116, China. 2 State Key Laboratory of Superhard Materials, College of Physics, Jilin University, Changchun 130012, China. 3 Department of Earth Sciences, University of Cambridge, Downing Street, Cambridge CB2 3EQ, UK. 4 Geophysical Laboratory, Carnegie Institution of Washington, Washington, DC 20015, USA. 5 Center for High Pressure Science and Technology Advanced Research (HPSTAR), Shanghai 201203, China.
