This review systematically evaluates the major hydrogen production pathways, spanning mature fossil-based processes, steam methane reforming, dry methane reforming, catalytic methane decomposition, and coal gasification, to emerging renewable routes including biomass gasification, water electrolysis, photolytic methods, and biological/biochemical processes. Each technology is critically assessed through integrated techno-economic and environmental analyses, examining efficiency, carbon intensity, technological readiness levels, and scalability potential. Life cycle assessments reveal that conventional methods, while cost-effective ($1.25–2.27/kg H<ce:inf loc=\"post\">2</ce:inf>), generate substantial CO<ce:inf loc=\"post\">2</ce:inf> emissions (9–20 kg CO<ce:inf loc=\"post\">2</ce:inf>-eq/kg H<ce:inf loc=\"post\">2</ce:inf>). Conversely, renewable pathways demonstrate significantly lower environmental impacts but face economic and technological barriers limiting commercial deployment. Key challenges identified include catalyst deactivation, high capital costs for electrolyzers, and low efficiencies in photolytic systems (∼5%). The review establishes strategic research priorities: developing durable, cost-effective catalysts; advancing high-temperature electrolysis technologies; integrating renewable energy systems; and scaling photobiological platforms. This analysis provides actionable insights for researchers, industry stakeholders, and policymakers to accelerate hydrogen technology development and deployment, supporting the transition toward a sustainable, hydrogen-based energy economy aligned with net-zero emission targets.","PeriodicalId":363,"journal":{"name":"Journal of Industrial and Engineering Chemistry","volume":"29 1","pages":""},"PeriodicalIF":6.1,"publicationDate":"2025-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144670047","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study employs 3D fast-paced organoid models derived from human-induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs) to investigate mitochondrial dysfunction and cardiac fibrosis in Afib at the molecular level. Rapid pacing at 3 Hz for 24 h triggered a 50 % decline in peak contraction amplitude and a 55 % reduction in contraction velocity. Multi-omics profiling revealed pronounced mitochondrial injury—succinate dehydrogenase sub-units SDHA–D decreased by 35–60 % and the master regulator PGC-1α fell 48 % together with a 2.3-fold increase in cytosolic cytochrome-c. Profibrotic signalling was activated in parallel (AGTR1 was up-regulated 2.1-fold, TGF-β1 was up-regulated 2.5-fold), driving extracellular-matrix accumulation (collagen-I and α-SMA levels rose 1.9- and 2.2-fold, respectively). Public Gene Expression Omnibus (GEO) datasets further validated the clinical relevance of our model; the organoid transcriptional fingerprint correlated strongly with human atrial-tissue fibrosis signatures (R = 0.71, p &lt; 0.001; GSE128188), highlighting its translational value. Collectively, these quantitative data demonstrate that 3-D fast-paced organoids recapitulate both the functional impairment and synchronous mitochondrial-fibrotic remodeling characteristic of early Afib. Taken together, coupling high-resolution functional metrics with multi-omics read-outs elevates cardiac-disease modelling and can accelerate the development of targeted therapies for atrial fibrillation.","PeriodicalId":363,"journal":{"name":"Journal of Industrial and Engineering Chemistry","volume":"40 1","pages":""},"PeriodicalIF":6.1,"publicationDate":"2025-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144515724","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
