However, achieving industrial-scale production remains challenging, as reconciling high current densities (>1 A cm−2) with product selectivity has yet to be realized. The realization of COR at ampere-level currents for acetic acid production remains hindered by the insufficient availability of highly active sites needed to facilitate CO coupling under high-flux conditions. Here, we developed a copper oxybromide catalyst that in situ generates a high density of grain boundaries (GBs) during COR, as evidenced by high-resolution TEM. Density functional theory calculations verified the high activities of GB-rich surfaces due to stronger *CO adsorption compared to flat Cu(111). Coupled with pressurized CO (10 atm), these rich GBs can effectively adsorb CO and promote this coupling, further leading to a record acetic acid partial current density of 2 A cm−2 (67% faradaic efficiency at 3 A cm−2 total current), outperforming the state-of-the-art Cu-based catalysts. This work introduces an effective catalyst for enabling industrial-scale COR, highlighting the critical role of structural design in achieving high-performance electrochemical conversion.","PeriodicalId":101138,"journal":{"name":"RSC Applied Interfaces","volume":" 5","pages":" 1417-1423"},"PeriodicalIF":0.0,"publicationDate":"2025-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/lf/d5lf00128e?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145021479","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 examines the key factors influencing the conversion process, including the physicochemical properties of solvents or solvent mixtures and the thermal pretreatment, of Ga-doped ZnO (ZnO : Ga). We have evidenced that the polarity, viscosity, and interfacial tension of the solvent significantly affect the dissolution of ZnO : Ga and the crystallization of ZIF-8. Methanol–water mixtures were found to effectively control the conversion process, with a 3 : 1 MeOH/H2O ratio being optimal for producing continuous ZIF-8 membranes. Additionally, it has been demonstrated that annealing can greatly enhance the reactivity of the oxide. However, while it enhances the dissolution of ZnO : Ga, excessively high temperatures can lead to over-dissolution, which hinders ZIF-8 formation. These insights are crucial for optimizing ZIF-8 layers on ZnO : Ga, paving the way for the development of highly selective chemiresistive sensors.","PeriodicalId":101138,"journal":{"name":"RSC Applied Interfaces","volume":" 5","pages":" 1345-1358"},"PeriodicalIF":0.0,"publicationDate":"2025-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/lf/d5lf00054h?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145021465","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}

Nanocomposite films were prepared from aqueous composite latexes at room temperature by drop casting, with conversion of GO to rGO via thermal treatment. The electrical conductivity reaches values of approximately 102 Sm−1 at high rGO contents in both systems, with higher values for physical mixing than miniemulsion at medium rGO loadings. The thermal conductivities increased with increasing rGO content with the highest values of approx. 0.4 W mK−1 – physical mixing systems gave higher thermal conductivities than miniemulsions.

Fabricating separators with a high lithium ion transference number (tLi+) and uniform pore structure is an effective strategy to homogenize Li+ flux and suppress dendrite growth. Here, hollow SnO2 nanospheres with high structural stability were synthesized through a solvothermal method for surface coating of a poly(ethylene-co-acrylic acid) (EAA) separator (EAA@SnO2). The EAA matrix enhances the tLi+ through the interaction of carboxyl groups with ions in the electrolyte, while hollow SnO2 nanospheres convert to LixSn during cycling, regulating Li+ flux and promoting uniform solid electrolyte interphase formation. The as-prepared separator-based Li symmetric cells demonstrate stable cycling for over 1000 h with a low overpotential of 17 mV. Additionally, the LiFePO4||Li cells with the EAA@SnO2 separator deliver an initial capacity of 116.6 mA h g−1 and a capacity retention of over 80.96% after 200 cycles at 5C. The utilization of metallic hollow SnO2 nanospheres for separator coating proves to be a promising strategy for high-performance LMBs.","PeriodicalId":101138,"journal":{"name":"RSC Applied Interfaces","volume":" 5","pages":" 1311-1319"},"PeriodicalIF":0.0,"publicationDate":"2025-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/lf/d5lf00101c?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145021470","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}

The toxicity concern becomes more severe with the release of nano-sized debris particles due to augmented interfacial interactions, even if the bulk counterpart is highly biocompatible. From this perspective, the present study aims to assess the in vivo toxicity, both local and systemic, of Mg1−xCaxSi1−xZrxO3 (x = 0–0.4) [MCSZO-X, X = 0–4] nanoparticles using a rat model. Initially, the in vitro cytotoxicity of varying concentrations (0.25, 2.5, and 25 mg ml−1) of MCSZO-X nanoparticles was evaluated using MG-63 cells. Cell proliferation increases after the early interfacial interactions. Following this, 100 μl of MCSZO nanoparticles (25 mg ml−1) was administered through intra-articular injection into the knee joint of male Wistar rats. Biochemical analyses revealed no pathological changes in the liver and kidney of the injected group of rats. Additionally, the histopathological analyses demonstrated that there is no inflammation resulting from interfacial interactions with injected nanoparticles in various organs such as the liver, heart, kidney and knee. Overall, these findings pave the way for further advancement in bone repair and implant design.","PeriodicalId":101138,"journal":{"name":"RSC Applied Interfaces","volume":" 5","pages":" 1331-1344"},"PeriodicalIF":0.0,"publicationDate":"2025-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/lf/d5lf00045a?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145021473","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}

The aluminium surfaces are modified with different long-chain fatty acids using a simple immersion technique. The modified aluminium surfaces exhibit excellent water-repellent properties with a static water contact angle of more than 150° and a sliding angle of less than 10°. The corrosion resistance of the modified surfaces was measured using a potentiodynamic technique in a 3.5% (w/v) NaCl solution. The Tafel plot shows an enhancement in corrosion resistance with a low corrosion current density and high corrosion potential after modification. The highest Ecorr value of −0.7819 V and the lowest corrosion current density of 1.48 × 10−6 A cm−2 are found to be for the octadecanoic acid coated sample. Furthermore, the rate of corrosion resistance is analysed based on the length of fatty acids. Additionally, the modified aluminium surface also shows a dirt-resistant nature. The performance of the coated surface was investigated under several operating conditions including elevated temperature, contact with highly acidic and alkaline solutions, and different mechanical tests (surface bending, water jet, tape-peeling, and abrasion using sandpaper), which fulfils the industrial suitability of aluminium after modification.","PeriodicalId":101138,"journal":{"name":"RSC Applied Interfaces","volume":" 5","pages":" 1359-1371"},"PeriodicalIF":0.0,"publicationDate":"2025-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/lf/d5lf00125k?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145021474","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}
