This study examines the advancements in ammonia combustion technology for spark ignition (SI) and compression ignition (CI) engines. An extensive analysis of the characteristics of ammonia (NH₃) combustion, a fuel free of carbon, is provided in this paper. Since ammonia burns similarly to fossil fuels and emits less CO₂, CO, NO_x, soot, and hydrocarbon (HC) pollutants, NH₃ is a desirable substitute fuel that can be stored and transported using existing commercial infrastructure. It also comes with productivity from renewable sources. However, unlike traditional hydrocarbon fuels, NH₃ exhibits unique combustion characteristics, highlighting the challenges of using it as a fuel for internal combustion (IC) engines. This paper critically reviews the challenges of NH₃ blended with diesel, biodiesel, dimethyl ether, and some other alternative fuels in IC engines. The literature reports mixed findings on this topic. Many studies have not demonstrated NH₃ as a substitute fuel for IC engines yet. In addition, ammonia's toxicity and unusual/complex combustion characteristics hinder its use as a fuel substitute in IC engines. Further research is required to overcome challenges associated with using NH₃ as a fuel for IC engines. This study identifies and discusses these challenges.</div></div>","PeriodicalId":418,"journal":{"name":"Renewable and Sustainable Energy Reviews","volume":"222 ","pages":"Article 115964"},"PeriodicalIF":16.3,"publicationDate":"2025-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144338971","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review recommends a comprehensive assessment of cooling technologies, highlighting their role in improving energy efficiency and supporting clean energy transitions while tackling challenges like stability, scalability, and material properties. The role of nanofluids and PCMs in thermal regulation is emphasized, as they efficiently manage transient heat loads by storing and releasing thermal energy, maintaining optimum operating temperatures, and mitigating thermal excursions. Advanced configurations, namely heat pipes and micro-channel heat exchangers demonstrate exceptional thermal management performance in high-heat flux scenarios. Heat sinks with their interconnected pore structures, enhance heat transfer through combined conduction and convective mechanisms. The integration of advanced materials substantially enhances thermal conductivity, heat dissipation, improved thermal stability, and operational efficiency. The integration of Artificial Intelligence and Machine Learning in thermal systems augments predictive modeling and adaptive control, leading to enhanced reliability and prolonged operational durability of system components and overall functionality.</div></div>","PeriodicalId":418,"journal":{"name":"Renewable and Sustainable Energy Reviews","volume":"222 ","pages":"Article 115954"},"PeriodicalIF":16.3,"publicationDate":"2025-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144338969","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

HDAC6 removes the acetyl group of acetyllysine from histones to regulate gene expression in the nucleus. However, with predominant localization in the cytoplasm, various cytoplasmic substrates of HDAC6 have also been identified. HDAC6 is unique among the other 11 metal-dependent HDAC family members due to the presence of two independent and active deacetylase domains. Recently, an inactive mutant of HDAC6 has been used as a trap to discover substrates of the second catalytic domain (CD2). Here, substrates of the first catalytic domain (CD1) of HDAC6 were explored using trapping mutants and proteomics analysis, with 21 putative substrates identified. Among them, the E3 ubiquitin ligase HUWE1 was validated as a novel HDAC6 substrate. Specifically, E3 ligase HUWE1 was deacetylated by HDAC6 CD1 to elevate degradation activity. HDAC6 CD1 also regulated the protein levels of E3 ligase UBR5.
