Herein, we synthesized a zero-dimensional (0D) hybrid antimony-based halide, [DMPZ]2SbBr6 Br·3H2O (DP-SbBr, DMPZ = N,N′-Dimethylpiperazine), via precise molecular-level design, which exhibits both efficient photoluminescence (PL) and nonlinear optical (NLO) properties. Notably, DP-SbBr crystallizes in the P21212 chiral space group, despite lacking chiral units, with isolated [SbBr6]3− octahedral units separated by organic molecules, forming a typical 0D hybrid structure. This unique structure enables efficient orange light emission with a 28.5% quantum yield. Additionally, DP-SbBr demonstrates a 0.32-fold second-harmonic generation (SHG) signal relative to KDP, showcasing its potential as a NLO material.

In this study, we report the fabrication of a cost-effective SERS substrate by thermally evaporating silver (Ag) onto the eggshell membrane (ESM), a low-cost and biologically sourced material, to create substrates with controlled surface morphologies. The silver coating thickness has been varied to optimize the signal enhancement and was evaluated with three different standard Raman active molecules: 4-mercaptobenzoic acid (4-MBA), 4-mercaptophenylboronic acid (4-MPBA), and rhodamine 6G (R6G)- as analytes. The developed substrates exhibited remarkable SERS activity with an Enhancement Factor (EF) of 0.12 ×106 for 4-MBA, 0.70 × 105 for 4-MPBA and 0.36 × 104 for R6G, respectively. The ESM with optimal silver deposition of a thickness of 20 nm exhibited significantly enhanced SERS signal, with improved sensitivity and detection limit for all the three molecular analytes.

However, the poor cycling stability of supercapacitors based on rice husk-derived activated carbon in KOH electrolyte severely limit its commercial application. In this study, the influence of different positive-to-negative electrode mass ratios on the cycling stability of supercapacitors was systematically investigated using rice husk-derived activated carbon as electrode materials. The results show that increasing the positive-to-negative electrode mass ratios significantly enhances the cycling stability of supercapacitors. In this process, the continuous increase in positive electrode potential is effectively suppressed, which avoid the oxidation of the positive electrode. When the positive-to-negative electrode mass ratio is increased from 1 to 2, the capacitance retention of the supercapacitors significantly increases from 27.9% to 96.4% after 10 000 charge–discharge cycles. Meanwhile, the specific capacitance is only reduced by 9.1%. The supercapacitor with positive-to-negative electrode mass ratio s of 1 and 2 shows energy densities of 10.68 W h kg−1 and 9.54 W h kg−1 at 0.5 A g−1, retaining 46.8% and 43.4% of energy densities at 20 A g−1. Adjusting the positive-to-negative electrode mass ratio does not significantly affect the electrochemical properties of supercapacitors. Thus, this work unfolds a new strategy for enhancing the cycling stability of activated carbon-based supercapacitors in alkaline electrolytes and a viable route for practical energy storage applications of rice husk-derived activated carbon in supercapacitors.","PeriodicalId":102,"journal":{"name":"RSC Advances","volume":" 32","pages":" 25940-25948"},"PeriodicalIF":3.9,"publicationDate":"2025-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/ra/d5ra03028e?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144666070","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigates the performance of BiFeO3 (BFO)-based perovskite solar cells using COMSOL Multiphysics simulations, focusing on the optimization of layer thicknesses and material properties. The results demonstrate that varying the thickness of the electron transport layer, absorber layer (BFO), and hole transport layer significantly impacts the short-circuit current density (Jsc), open-circuit voltage (Voc), and power conversion efficiency. Key findings include an optimal BFO thickness of 1210 nm, which balances light absorption and recombination losses, and a peak efficiency of 11.80% was observed.

Cellulose is attracting increasing attention as a sustainable filler candidate due to its renewability, abundance, and favorable mechanical properties. Its application in polylactic acid (PLA)-based composites has been extensively studied and has demonstrated improvements in mechanical strength, barrier properties, and processability. However, the use of nanocellulose in other biodegradable polymers such as poly(butylene succinate) (PBS) and poly(butylene adipate-co-terephthalate) (PBAT) remains limited, despite their industrial significance. In this study, we developed matrix-adapted cellulose nanoparticles by grafting PBS or PBAT onto cellulose regenerated from aqueous sodium hydroxide solution. Grafting was carried out via melt polycondensation, resulting in nano-sized particles with average sizes of approximately 100 nm for PBS and 175 nm for PBAT. These surface-modified particles exhibited improved thermal stability and high polymer content, reaching 25 wt% for PBS and 50 wt% for PBAT, indicating successful grafting, which is expected to facilitate compatibility with the target biodegradable matrices.

TAA facilitates detection of Hg2+ by a “naked-eye” color change from yellow to colorless in visible light, and fluorescence ‘turn-off’ in UV light (365 nm). The observed fluorescence quenching is due to the chelation-enhanced fluorescence quenching (CHEQ). TAA exhibited excellent selectivity and sensitivity toward Hg2+ ions, even in the presence of competing cations. The binding constant (Ka) for Hg2+ ions was found to be 3.4 × 105 M−1, indicating a strong binding affinity. The binding mechanism was elucidated using DFT calculations and supported by LC-MS and FT-IR studies. TAA forms a 1 : 1 complex with Hg2+ ions, as confirmed by Job's plot analysis. Additionally, the colorimetric limit of detection was found to be 0.67 μM, while the fluorometric limit of detection was found to be 0.24 μM, which demonstrates the high sensitivity of TAA towards Hg2+.
