Because of its extreme toxicity, there is growing concern about its presence, necessitating timely detection to ensure human welfare. However, detecting H2S in various environments, including air and water, remains a significant challenge. To develop a probe for sulphide ion detection, herein, we report the synthesis of a highly selective, sensitive, and colorimetric chemosensor (NATRP) for the detection of sulphide ions (S2−) in a 50% aqueous medium. NATRP demonstrates exceptional sensitivity and selectivity for S2− ions relative to other ions, with a limit of quantification of 26 nM and a detection limit of 7.9 nM. It shows aggregation-induced emission quenching, which upon the addition of S2− ions, disaggregates with enhancement in fluorescence intensity. This enables NATRP to detect S2− ions within 15 seconds and it demonstrates good pH stability, suggesting that NATRP can detect sulphide ions across a broad pH range. The mechanism underlying the detection involves the reduction of azide groups to amine groups in the presence of S2− ions, confirmed by NMR titrations and HRMS analysis. Furthermore, NATRP successfully detects S2− ions in water, serum and solid samples, as well as in live cell imaging in bacterial cells. Moreover, UV-visible and fluorescence data have been employed to construct 1-to-2 decoders.","PeriodicalId":18242,"journal":{"name":"Materials Advances","volume":" 13","pages":" 4389-4401"},"PeriodicalIF":5.2,"publicationDate":"2025-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/ma/d5ma00103j?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144519612","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study presents the development of an organic molecule stabilized nickel ferrocyanide (NFC) hybrid material, synthesized through a complexation-mediated approach, which demonstrates outstanding electrochemical performance, making it a promising candidate for high-efficiency supercapacitor applications. X-ray diffraction analysis confirms the formation of nickel ferrocyanide with a cubic crystal structure (space group: Fm<img>m). Transmission electron microscopy analysis revealed spherical shaped nickel ferrocyanide particles within the size range of 2–4 nm. Fourier-transform infrared spectroscopy, Raman spectroscopy, and X-ray photoelectron spectroscopy confirmed the successful formation of nickel ferrocyanide and offered detailed insights into its bonding environment and chemical states. The electrochemical performance of the hybrid material displayed a specific capacitance of 298 F g−1 at 6 A g−1 and retained 88% of its original capacitance after 10 000 cycles in a three-electrode system. An asymmetric supercapacitor device, fabricated using NFC as the cathode and activated carbon as the anode electrode, delivered a specific capacitance of 94 F g−1 at 1.0 A g−1. The device exhibited maximum specific energy and specific power values of 44 W h kg−1 and 6067 W kg−1, respectively, with a moderately good cycle life (84% capacitance retention after 10 000 cycles). The results emphasize the potential of the NFC-based hybrid system as an efficient material for energy storage applications.","PeriodicalId":18242,"journal":{"name":"Materials Advances","volume":" 13","pages":" 4345-4356"},"PeriodicalIF":5.2,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/ma/d5ma00352k?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144519554","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, a newly synthesized alkyne-functionalized ionic liquid, 1-hexadecyl-3-propargyl imidazolium bromide (HDPI), was chemically attached on the surface of azide-modified mesoporous silica nanocarriers (mSiO2, av. size 110 nm) based on the Menshutkin reaction and copper-catalyzed click chemistry. The HDPI-functionalized mSiO2 nanocarriers were loaded with tetracycline (TC) to develop a dual-action drug delivery system. Time-dependent drug release studies conducted at pH 7.4 and 37 °C over 48 h revealed controlled TC release. The long alkyl chain of the surface-bound ionic liquids (ILs) facilitated bacterial cell wall penetration, enhancing TC transport into both Gram-positive and Gram-negative bacteria. This dual-action mechanism was validated through antibacterial assays demonstrating that the surfactant-like IL disrupts bacterial cytoplasmic membranes, while the antibiotic induces cell death. Given the inherent antibacterial properties of ILs, we further investigated their ability to form stable, hydrophobic, and antimicrobial coatings on glass substrates under different environmental conditions. The results indicate that these IL-based coatings are uniform, durable, and hold significant potential for applications in healthcare and industry.","PeriodicalId":18242,"journal":{"name":"Materials Advances","volume":" 13","pages":" 4220-4232"},"PeriodicalIF":5.2,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/ma/d4ma01267d?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144519513","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Considering the significance of natural molecules as precursors, cinnamic acid (CA) was used to develop carbon dots (CA-CDs) using an efficient microwave irradiation method which gave a higher quantum yield in comparison with other conventional methods. The positively charged CA-CDs showed a broad spectrum of action against Gram-positive (S. aureus) and Gram-negative (E. coli) bacteria. Unlike ciprofloxacin (CIP), CA-CDs showed potent inhibition of clinically resistant S. aureus (SA-DR) while reducing biofilm production, leading to synergy with CIP. CA-CDs also acted as carriers to enhance the skin-permeability of CIP through their ionic complex (CIP-CA-CDs). The complex retained the antimicrobial properties and showed the ability to gradually release CIP like a reservoir. Considering the poor permeability of CIP as a limitation, this work can encourage the translational application of CIP for topical application. This work provides a novel method of developing CDs for antimicrobial properties and can encourage their use as a complementary therapy or as carriers for further application.","PeriodicalId":18242,"journal":{"name":"Materials Advances","volume":" 13","pages":" 4239-4253"},"PeriodicalIF":5.2,"publicationDate":"2025-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/ma/d5ma00247h?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144519451","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among them, copper antimony sulfide is a promising ternary metal sulfide. Copper antimony sulfide possesses four accessible phases, which have great potential in solar energy conversion and photocatalysis due to their energy levels and optical properties. However, the synthesis often requires high temperatures and prolonged reaction times. While the different phases are already well characterized, insights into their formation processes from specific precursors, which can enable targeted optimization of material properties, still remain largely unexplored. In this study, we investigated thin films of the two phases chalcostibite (CuSbS2) and tetrahedrite (Cu12Sb4S13), prepared from metal xanthate precursors. We used temperature-dependent grazing incidence X-ray scattering to analyze their thermal conversion process and crystal growth in detail. Furthermore, we evaluated their photocatalytic performance, revealing a good specific catalytic activity of 52 μmol g−1 h−1 for chalcostibite in methylene blue degradation. Additionally, tetrahedrite demonstrated high co-catalytic performance for hydrogen evolution in combination with mesoporous titania, achieving a specific activity exceeding 2.5 mmol g−1 h−1.

The catalyst prepared via the deposition method showed the highest activity. The catalysts were identified using XRD, FTIR, SEM, UV-Vis DRS, and cyclic voltammetry (CV). The crystallite size of the binary catalyst was obtained at about 25.3 nm and 45 nm by the Scherrer and Williamson–Hall methods. Since the response surface methodology (RSM) is one of the efficient modeling methods, it was used to investigate the simultaneous effects of the effective parameters (catalyst amount, pollutant concentration, pH, and irradiation time) on the photocatalytic degradation. R2 showed good agreement between the experimental results and the data predicted by the software. Also, the predicted square model was very satisfactory with high correlation coefficients R2 (0.9839) and adj R2 (0.9688). The optimal-run conditions were CEBT: 15 ppm, catalyst dose: 0.9 g L−1, pH: 7.3, and illumination time: 20 min. The effect of some inhibitory agents was evaluated, and it was found that the role of superoxide radicals and the holes in the degradation of EBT is more critical than that of hydroxyl radicals and photoinduced electrons, based on the direct Z-scheme mechanism proposed for charge carriers’ transfer.
