Hydrogen plays an important role in transportation, power generation, and other fields. Therefore, developing electrochemical (P2X) technology for renewable energy consumption effectively solves renewable energy curtailment.\u0000Methods: The four aspects of market scale, technical route, energy conversion efficiency, and demonstration project progress are reviewed, and the energy efficiency of the four electrochemical technologies is compared, Power consumption, marginal electricity price, equivalent output, and market share five major technical and economic indicators. To analyze the strengths, weaknesses, opportunities, and threats of P2X in China, a literature review survey was conducted, relying on recent two-decade publications from four main publishers: Scopus, Springer, Wiley, and Taylor and Francis. Keywords were selected from the first-hand references based on their impact on P2X or related topics listed in the literature databases. The keywords as Power to X, Power to chemicals, PtX, and P2X were chosen according to their actual involvement or keen interest in P2X projects.\u0000Results: The research results based on the low-temperature electrolysis technology route show that the comprehensive energy efficiency of the electricity-to-methane and electricity-to-gasoline technologies is higher (50%); the electricity-to-gasoline technology is the most economical (marginal electricity price is 0.37 yuan/kWh), but the synthesis process requires carbon monoxide and carbon emissions, And the technical risk is high; the promotion of electricity to ammonia will have the greatest impact on the market (17.18%). Reducing coal consumption by about 22.85 million tons and the environmental protection significance of electricity-to-ammonia conversion (reducing carbon emissions by about 39.1 million tons) are two important directions for future electrochemical technology.\u0000Conclusion: Facing the development of P2X technology in the future, the plan and economics of the high-temperature electrical and chemical technology route based on high-temperature solid oxides were preliminary discussed and prospected.","PeriodicalId":322389,"journal":{"name":"International Journal of Chemistry Research","volume":"218 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131405282","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}

Meanwhile, the spike proteins play a major role in knowing the profound way out to curtail the respective infectivity. S1 and S2 act as the two main subunits to render prime significance to reveal the interaction of surface-active agents in this context. Keeping in view the importance of surfactants in developing effective treatment and vaccine for the coronavirus infectious disease-2019 (COVID-19), this article describes the surface chemistry of this quest. The surface action being the main mode of infectivity can thus be halted by using surface-active compounds (surfactants). Therefore, this review emphasizes the sound role of surface action linked with COVID-19 treatment and vaccination.","PeriodicalId":322389,"journal":{"name":"International Journal of Chemistry Research","volume":"303 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121269952","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}

Average amino acid content comparison, results, in the rainy season, maximum amino acid content was in Deosar and minimum in Singrauli, In winter amino acid is higher in Waidhan and minimum in Deosar and maximum amino acid content was recorded intended for Waidhan and minimum for Deosar in summer. Concentration of amino acid in cow milk was found to be in order of glycine<histidine<alanine<methionine<isoleucine<phenylalanine<threonine<tyrosine<serine<lysine<valine and aspartic acid<arginine<leucine<proline<glutamic acid. Amino acid status in buffalo milk sample was found in order Glycine<histidine<methionine<alanine<phenylalanine<isoleucine<threonine<arginine<tyrosine<serine and lysine<aspartic acid<valine<leucine<proline<glutamic acid. All the amino acids are evaluated as per the mean (n = 6) mean±SD.\u0000Conclusion: It is concluded that cow and buffalo milk samples contained all the amino acids but differed in the contents of certain amino acids. Such variation is purely biological and genetic and is intended for the nourishment of the young. The current investigation would be valuable for the dairy processing industries to formulate nutritionally improved milk-based functional products for a vulnerable segment of the population.","PeriodicalId":322389,"journal":{"name":"International Journal of Chemistry Research","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125312599","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}

The reaction of ethyl (S)-2-amino-2-phenylacetate with Boc anhydride and hydrazine produces ethyl (S)-2-((tert-butoxycarbonyl)amino)-2-phenylacetate. The intermediate 5-alkyl amino-1,3,4-oxadiazole-2-thiols have been isolated as stable compounds.\u0000Results: To study the characteristics of these compounds, they are subjected to 1HNMR, 13CNMR, and IR. These studies examine the chemical structure of synthesized compounds. The mass of the novel compounds was established with the help of the LCMS test. The structural and optical properties were examined by the powder XRD and photoluminescence spectrum respectively.\u0000Conclusion: The sharp intense peak in the powder XRD indicates the crystal nature of the sample. The values obtained from the LCMS test indicate that the compounds have good thermal stability. The absorption peak at 358 nm in the PL spectrum indicates that the sample can be used in photoelectronic devices.","PeriodicalId":322389,"journal":{"name":"International Journal of Chemistry Research","volume":"181 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134379305","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}
