To fully utilize hot electrons from the localized surface plasmon resonance (LSPR) effect, a sufficient metal-semiconductor contact is essential for efficient electron transfer to reactive centers. Herein, an Au@In2O3 core-shell structure is reported, where the incorporation of Au extends the light absorption of In2O3 into the visible region. Under illumination, hot electrons produced by the Au LSPR effect are efficiently transferred across the Au-In2O3 interface to In2O3, resulting in a 56% enhancement in methanol production rate compared to dark conditions. This work expands the compositional scope of AR systems and provides a valuable reference for designing catalysts for photo-assisted thermal/photothermal catalytic CO2 hydrogenation to methanol.","PeriodicalId":54339,"journal":{"name":"ChemNanoMat","volume":"11 6","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144256503","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Förster energy transfer process wherein the amino acid Trp in proteins transfers its energy to an acceptor (dansyl) is examined. This study includes both steady-state and time-resolved fluorescence techniques, examining the interaction with free and liposome-embedded probes. The modification of dansyl is straightforward and high throughput, making it highly attractive. Photophysical characterization of lauryl dansyl reveals solvatochromism, with bathochromic shifts in emission correlating with increasing medium polarity, allowing us to characterize the polarity of the probe environment in different membrane systems. The probe displays the anticipated affinities for liposome–protein interaction, confirming its potential use.

Herein, hydroxyapatite (HA) is synthesized from Sepia officinalis, which is a naturally rich source of calcium and magnesium, and incorporated into polyacrylonitrile (PAN) nanofibers through electrospinning. The dual-layer membrane consists of an electrospun HA/PAN nanofiber top layer and an amoxicillin-loaded cellulose acetate (aCA) bottom layer, designed for controlled antibiotic release to provide antimicrobial protection essential for osteogenesis. The uniform distribution of HA nanoparticles within the PAN nanofibers enhances porosity and reduces hydrophobicity. The physicochemical properties and morphology of the membrane are characterized using scanning electron microscopy, X-ray photoelectron spectroscopy, tensile strength analysis, and water contact angle measurements. In vitro studies confirm that the HA/PAN@aCA membrane supports the adhesion, proliferation, and differentiation of L929 fibroblasts and MG-63 osteosarcoma-derived cells, promoting mineralized nodule formation. Additionally, the scaffold demonstrates significant antimicrobial activity with controlled amoxicillin release, effectively preventing microbial contamination and facilitating bone regeneration.

This study uses advanced simulations with OghmaNano to explore the influence of electron transport layers (ETLs) and hole transport layers (HTLs) in cesium-based PSCs, specifically with Cs2AgBiBr6 as the absorber material. By analyzing ZnO, SnO2, and TiO2 as ETLs and NiOx and Cu2O as HTLs, this study determines the impact of layer properties and thickness on critical performance metrics, including PCE, Voc, and Jsc. The study's simulations reveal that optimal absorber layer thicknesses are 100 nm for ZnO and SnO2 and 400 nm for TiO2, achieving a peak PCE of 17.11% in the TiO2/Cu2O configuration. This study also observes that SnO2-based devices exhibit superior charge extraction capabilities due to reduced trap states, leading to a more stable voltage output. Additionally, photon recycling effects in Cs2AgBiBr6 increase Jsc by up to 5%, a novel finding for cesium-based PSCs. Energy-level alignment analysis shows that TiO2/Cu2O minimizes recombination, enhancing fill factor and efficiency. Photon density distribution and energy-level spectra reveal the interplay between optical absorption, charge dynamics, and interface energetics, guiding device architecture optimization.

The oxygen evolution reaction (OER) is a key step in this process, necessitating efficient electrocatalysts to accelerate the inherently sluggish and complex reaction kinetics. Noble metal catalysts are considered the most efficient OER catalysts. However, their high cost and scarcity limit their extensive application. In contrast, transition metal–based compounds (TMCs) catalysts have attracted widespread attention due to their high electronic conductivity, tunable electronic configurations, and relatively low cost. Nevertheless, achieving long-term stability in alkaline media for these catalysts remains a severe challenge. The research progress regarding the active sites of the transition metal elements in alkaline OER is summarized. More importantly, this review delves into strategies aimed to enhancing the activity and stability of TMCs catalysts, adopting an electronic modulation perspective. These strategies encompass defect, doping, and interface engineering. Moreover, this review reveals the OER mechanism and current development status of TMCs catalysts from the perspective of catalyst dynamic reconstruction. Finally, some challenges and prospects for improving the performance of TMCs catalysts are proposed.
