In the present investigation, Cu₂O NPs were synthesized via an eco-friendly, biologically-mediated process utilizing Muntingia calabura fruit extract (MCFE), which acted both as a reducing and stabilizing agent. The successful formation of Cu₂O NPs was meticulously characterized using an array of advanced analytical techniques, including UV–vis spectroscopy, XRD, SEM, and FTIR spectroscopy. These comprehensive characterizations collectively affirmed the successful synthesis, crystallinity, and surface functionalization of the nanoparticles. Subsequently, the Cu₂O NPs were employed as highly efficacious catalysts in the copper-catalyzed azide-alkyne cycloaddition (CuAAC) reaction—an exemplary instance of click chemistry—facilitating the synthesis of 1,4-disubstituted-1,2,3-triazoles under mild, solvent-free conditions. The catalytic efficacy of the Cu₂O NPs was systematically assessed in terms of reaction yield, selectivity, and recyclability, demonstrating remarkable catalytic performance and sustainability. In parallel, the bioactivity of the Cu₂O NPs was rigorously evaluated, revealing significant antioxidant properties, in addition to potent antibacterial and antifungal activity against a broad spectrum of pathogenic microorganisms. These findings not only underscore the diverse potential of Cu₂O NPs in catalytic applications but also highlight their considerable promise as bioactive agents.","PeriodicalId":146,"journal":{"name":"ChemistrySelect","volume":"10 29","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144716607","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review manuscript explores the role of decolorization within the framework of a circular economy, examining the challenges associated with various dye types and the techniques used for their removal. While conventional methods often rely on harsh, toxic chemicals, growing attention is being directed toward advanced approaches such as advanced oxidation processes (e.g., UV and ozone treatment, Fenton oxidation), photocatalytic decolorization, supercritical CO₂-based methods, and enzymatic decolorization. These innovative techniques offer promising alternatives but also present technical and economic challenges. The review emphasizes the need for the development of efficient, cost-effective, and environmentally friendly decolorization technologies to support scalable textile recycling and advance the transition to a more sustainable textile industry.","PeriodicalId":146,"journal":{"name":"ChemistrySelect","volume":"10 29","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144725557","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

UV–vis spectroscopy monitored the synthesis, revealing significantly faster kinetics with Curcumin (∼0.0083 min⁻¹) compared to Teak extract (∼0.0038 min⁻¹).

Crucially, antimicrobial assays demonstrated a remarkable enhancement in efficacy for the biogenically capped ZnO NPs. Curcumin-capped ZnO NPs exhibited superior antibacterial (1.095 cm inhibition) and antifungal (0.764 cm inhibition) activities against both pathogens, outperforming bare ZnO NPs and Teak-coated counterparts. This enhanced activity is attributed to a synergistic effect, likely involving reactive oxygen species generation and membrane disruption.

However, the fundamental influence of annealing atmospheres on ORR activity remains elusive. Herein, flexible carbon cloth (CC) is thermally activated under various atmospheres, including air, N2, and H2/Ar. Comprehensive characterizations reveal that the oxidative air atmosphere introduces oxygen functionalized sp3 defects that synergistically enhance the 2e− pathway for hydrogen peroxide (H2O2) generation. In stark contrast, the inert (N2) or reductive (H2/Ar) atmospheres largely preserve graphitic domains, resulting in inferior catalytic activity. Benefiting from the oxidative thermal activation, the optimized CC achieves unprecedented H2O2 selectivity of 94.7–97.6% and a half-wave potential (E1/2) of 0.69 V. The excellent electrochemical performance is ensured by the good balance between the surface defect density (ID/IG = 1.042), oxygen content (11.07 at.%), and overall structure integrity.

However, exceeding the critical filler concentration threshold causes nanoparticle aggregation, limiting further output performance enhancement of TENG. Here, a novel approach is proposed to enhance TENG output performance by doping lanthanum (La) into bismuth ferrite (BFO), forming La-doped BFO nanoparticle fillers (BLFO) to further improve the output performance of polyvinylidene fluoride (PVDF)-based TENG without increasing filler concentration. This approach overcomes the limitation of nanoparticle aggregation at high filler loadings while significantly enhancing the output performance of TENG. Below the critical concentration threshold, the dielectric constant of BLFO/PVDF composites increases by 32% compared to undoped BFO/PVDF composites. Consequently, the BLFO/PVDF-based TENG achieves a high output voltage of 329 V and short circuit current of 44 µA, representing 43% and 69% increases over the BFO/PVDF-based TENG, respectively. Notably, these values represent 219% and 193% increases compared to the pure PVDF-based TENG. Furthermore, a self-powered anticorrosion system powered by the BLFO/PVDF TENG demonstrates effective metal protection, as evidenced by open-circuit potential measurements and reduced average corrosion rates.","PeriodicalId":146,"journal":{"name":"ChemistrySelect","volume":"10 29","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144716639","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, UV–visible absorption spectra of a-GQDs with and without Pb2+ and Cu2+ ions, shows no variation in the absorbance of a-GQDs. Further, lifetime analysis of a-GQDs shows that lifetime of a-GQDs changed from 2.02 ns to 1.37 ns in presence of Pb2+ and 2.02 ns to 1.62 ns in presence of Cu2+ ions, confirms the dynamic quenching mechanism.
