This article reviews various decontamination methods, analysing their respective strengths and weaknesses against chemical warfare agents including vesicants: sulfur mustard (bis(2-chloroethyl) sulfide, HD; nitrogen mustards; bis(2-chloroethyl)ethylamine (HN1), bis (2-chloroethyl)methylamine (HN2), tris(2-chloroethyl)amine (NH3) and Lewisite; nerve agents sarin (isopropyl methylphosphonofluoridate, GB), soman (pinacolyl methylphosphonofluoridate, GD), tabun (Ethyl <em>N,N’</em>-dimethylphosphoroamidocyanidate, GA) and VX, (ethyl <em>N-</em>2-diisopropyl aminoethyl methylphosphonothiolate); vomiting agent Clark I (diphenylchloroarsine, DA). Traditional decontamination approaches include hydrolysis, which utilises water for CWA breakdown, and chlorine-based decontamination, known for its effectiveness despite environmental drawbacks. Advanced oxidation processes (AOPs) offer efficient CWA destruction using highly reactive radicals but can be complex to implement. Emerging materials such as metal-organic frameworks (MOFs) have the potential to revolutionise the field of chemical warfare agent decontamination due to their high surface area and tunable structures. Additionally, polyoxometalates (POMs), zeolites, and reactive polymers are being investigated for their catalytic and adsorptive properties in CWA degradation. This review highlights the necessity for continuous research to develop efficient, safe, and environmentally friendly decontamination methods. The potential of combining existing approaches and tailoring novel materials, such as MOFs and reactive polymers, paves the way for significant advancements in CWA decontamination.</div></div>","PeriodicalId":15759,"journal":{"name":"Journal of Environmental Chemical Engineering","volume":"12 6","pages":"Article 114243"},"PeriodicalIF":7.4,"publicationDate":"2024-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142357453","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The ability of microalgae to respond to different stress conditions tends to cause epigenetic changes that influence the bioenergy potential of microalgae. This comprehensive review delves into the importance of understanding these epigenetic changes in microalgae and how they can be manipulated to enhance bioenergy potential. The review shows how epigenetic changes in oxidative phosphorylation cause a change that affects cellular energy homeostasis and signal transduction pathways, leading to altered metabolic profiles and stress adaptation strategies. This metabolic change was linked to the change in the gene expression level of different proteins, including Nicotinamide adenine dinucleotide (NADH) dehydrogenase, cytochrome, and ATPase synthase. The epigenetic change in this protein trigger a change in energy production and photosynthesis efficiency in microalgae, which are vital for the biosynthesis and accumulation of important metabolites useful for biofuel production. The manipulation of these proteins will facilitate the redirection of metabolic flux towards increasing lipid accumulation in microalgae, leading to increased biofuel potential.</div></div>","PeriodicalId":15759,"journal":{"name":"Journal of Environmental Chemical Engineering","volume":"12 6","pages":"Article 114266"},"PeriodicalIF":7.4,"publicationDate":"2024-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142416258","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
