It is demonstrated that C(s) Ns act as an efficient supporting material, thereby enhancing the sensor performance of Cu nanocrystals. Compared to pure Cu, the C@Cu Ns show enhanced sensor performance toward glucose, sodium nitrite, and formaldehyde. A comprehensive analysis was carried out to investigate the mechanism of enhanced sensor performances. Furthermore, the effects of Cu loading rates and the sizes of C Ns on sensor performance were systematically examined. In alkaline solutions, the sensitivity of C(s)@Cu-8% [ C(s) Ns with Cu 8 at% loading rate] in detecting glucose and formaldehyde was 1.94-fold and 3.06-fold higher than that of Cu nanocrystals, respectively. In neutral solutions, the sensitivity of C(s)@Cu-8% for detecting NaNO<ce:inf loc=\"post\">2</ce:inf> was 3.49-fold higher than that of Cu nanocrystals. As applied in actual substances, the obtained C(s)@Cu Ns could achieve the detection of NaNO<ce:inf loc=\"post\">2</ce:inf> in aqueous solutions and sugar content in Nescafé. This work introduced an economical sensor that features multifunctionality and enhanced performance, the utilization efficiency for Cu nanocrystals was enhanced while maintaining cost-effectiveness.

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 < 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}
