We discover four phases within the crystalline lithium-boron-sulfur (LBS) system, Li5B7S13, Li2B2S5, Li3BS3, and Li9B19S33, with exceptional DFT based single crystal ionic conductivity values at room temperature of approximately 74 mS cm–1, 10 mS cm–1, 2 mS cm–1, and 28 mS cm–1 respectively. To our knowledge, our prediction gives Li5B7S13 the second-highest reported DFT-computed single crystal ionic conductivity of any crystalline material. We compute the thermodynamic electrochemical stability window widths of these materials to be 0.50, 0.16, 0.45, and 0.60 V. Individually, these materials exhibit similar or better ionic conductivity and electrochemical stability than the best known sulfide-based solid-state Li-ion electrolyte materials, including Li10GeP2S12. However, we predict that electrolyte materials synthesized from a range of compositions in LBS system may exhibit even wider thermodynamic electrochemical stability windows of 0.63 V and possibly as high as 3 V or greater. The LBS system also has low elemental cost of approximately 0.05 USD/m2 per 10 μm thickness, significantly lower than that of germanium-containing LGPS, and a comparable mass density below 2 g/cc. These fast conducting phases were initially discovered by a machine learning-based approach to screen over 12,000 solid electrolyte candidates, and the evidence provided here represents an inspiring success for this model.","PeriodicalId":337638,"journal":{"name":"EngRN: Materials in Energy (Topic)","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124498028","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this regard, increasing the consumption of energy is one of the most critical challenges that humans are facing. Because, on the one hand, the untapped use of different sources of energy from fossil fuels can destroy this natural resource and, on the other hand, pollution from the use of these resources is a serious threat to the environment. Recent research suggests that affordable, sustainable and environmentally friendly fuels, which can be a good alternative to fossil fuels, have become more important. Therefore, biodiesel has made it possible to release less greenhouse gas emission and low toxicity emissions, which can partly meet fuel requirements and is the best alternative for petroleum diesel. In addition, the waste cooking oils are a major source of biodiesel for their essential compounds, such as glycerol. The use of waste cooking oils can reduce biodiesel production cost by 60 to 90 percent. Therefore, the main objective of this review is to study the production of biodiesel using transesterification reaction of waste cooking oil as an alternative fuel to petroleum diesel that can be used easily in diesel engines.","PeriodicalId":337638,"journal":{"name":"EngRN: Materials in Energy (Topic)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133096431","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper reviews existing interconnection and net metering policies instituted by investor owned utilities (IOUs) across the U.S., specifically focused on policies regulating installations of small scale, residential or Tier 1 (a term used to indicate policies applicable to smaller scale rather than larger scale, although the size at which DG systems are classified as either Tier 1 or higher tiers varies by utility). Publicly available data from each IOU reveal inconsistencies in interconnection and net metering policies, within states and even within individual companies. In addition, accurate information is often unavailable to consumers. Perhaps most importantly, results suggest that compensation for excess distributed generation often lacks transparent articulation in utility policy. The results of this study provide important insight into interconnection and net metering policies for distributed renewable energy generation, as states and utilities continue to modify interconnection and net metering policies in response to increased adoption of distributed renewable energy systems.","PeriodicalId":337638,"journal":{"name":"EngRN: Materials in Energy (Topic)","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124080816","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
