However, achieving phosphorescent materials with ultralong lifetimes is engaging and challenging. In this work, the indolo[3,2,1-j,k]carbazole (ICZ) with excellent planarity is obtained through twice single-bond locking on triphenylamine (TPA). Doping ICZ into a rigid matrix, URTP materials with a lifetime of 3.24 s and a photoluminescence quantum yield of 37.37% is successfully prepared.. The analysis of single-crystal, temperature-dependent photophysical characterization, Huang–Rhys factor, and theoretical calculations demonstrates that it is possible to make the molecules more planar and rigid by single-bond locking, which can inhibit the structural relaxation of the excited state and thus reduce the nonradiative transition to generate URTP. In addition, we achieve full-color afterglow by energy transfer. The potential applications of anticounterfeiting and optoelectronic information display of these URTP materials have been conducted. This work is an important reference for the construction of URTP materials.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"6 12","pages":"5384–5391 5384–5391"},"PeriodicalIF":9.6,"publicationDate":"2024-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142756452","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Given the interactions between the positive electrode design and the electrolyte, the development of Li–S electrodes requires comprehensive reporting of parameters to enable a comparison of developments. By developing a tool to aggregate synthesis parameters with cell performance, we summarize the frequency with which different components and electrochemical testing conditions are used, including data from 100 articles. Grouping reported capacity data by composite carbon type, C rate, and sulfur content revealed widespread variation in the maximum capacity and rate of degradation.

However, the obscure quantification of oxygen-release behavior has hindered the development of highly active and robust electrocatalysts. Herein, based on theoretical guidance, graphene confined SnOx nanodots (rGO@SnOx ND) holding the capacity for in situ formation of reaction-induced oxygen vacancies were prepared and taken as the model catalyst. Operando X-ray absorption fine structure (XAFS) quantitatively analyzed the reversible oxygen-released behavior, promoting the SnOx lattice modulation of the adsorption of *OCHO intermediate. These structure changes further facilitate the exceptional performance, yielding a peak jformate of 567 mA cm–2, a selectivity of 92.5% and a 50 h long-term stability of rGO@SnOx ND. The findings significantly advance the comprehensive understanding of the quantitative relationship between controllable oxygen vacancies and reaction activity, highlighting the capabilities of operando spectroscopy toward much wider metallic oxide-based electrochemical systems.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"6 12","pages":"5375–5383 5375–5383"},"PeriodicalIF":9.6,"publicationDate":"2024-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142756450","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These microgels demonstrate high sensitivity, detecting CO2 at concentrations as low as 300 ppm, surpassing conventional methods. The metal centers in the microgels can be constructed by coordinating with metal ions such as Mn2+, Cr3+, Ni2+, Cu2+, and Zn2+. Upon absorption of CO2, the system becomes weakly acidic, enabling multifunctional applications. Notably, Cu2+-based microgels display catalytic versatility, acting as carbonic anhydrase in neutral to alkaline conditions and as laccase or peroxidase in neutral to acidic environments. This versatility highlights their potential for transforming water pollutants across a broad pH range, offering significant promise for environmental remediation.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"6 12","pages":"5340–5347 5340–5347"},"PeriodicalIF":9.6,"publicationDate":"2024-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142756520","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main therapeutic drug, minoxidil, is limited by its poor efficacy and side effects such as contact dermatitis and hypertrichosis. Nitric oxide (NO), an endothelial-derived relaxing factor, promotes angiogenesis and accelerates blood flow, enhancing nutrient supply similar to minoxidil. Accordingly, we utilized a poly(vinyl alcohol) film (PVA) loaded with hyaluronic acid (HA) liposomes to construct a multistage transdermal NO delivery system (PVA@HL/NONOate) for the treatment of AGA. The HA liposomes provided efficient NO loading and extended release, while the PVA film improved skin penetration and sustained NO release, increasing NO bioavailability. Low-concentration NO effectively enhanced hair follicle vitality and repaired blood vessels. Mechanistically, low-concentration NO could treat AGA mainly by regulating the HIF-1 signaling pathway to promote angiogenesis, reducing inflammation by downregulating the expression of TNFRSF9 and IL-6, repairing hair follicles by downregulating the expression of genes in the CXCL5-IL-17 inflammatory axis.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"6 12","pages":"5354–5362 5354–5362"},"PeriodicalIF":9.6,"publicationDate":"2024-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142756521","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Three distinct doping patterns involve two identical or different transition metals across 27 candidates. Machine learning (ML) based models were developed with high accuracy to predict the catalytic activity of unknown catalysts. The scaling relation between the adsorption energies of *CO and *CHO is circumvented by regulating the local environment with preferential dual atom doping. The integrated DFT+ML approach identifies 14 and 8 most suitable DAAs for C1 and C2 product formation, respectively.
