However, cancer-causing cobalt ions may be released in vivo during articulation. Bacterial infection and biofilm formation on the implant surface are also contributing factors to the failure of these implants. Systemic or localized antibiotics are often not effective against such bacterial infections. Naturally, there is a need to design alloys that show inherent bacterial resistance with minimal release of cobalt ions. This study uses a potential biomedical alloy with copper (Cu) to provide inherent bacterial resistance and hydroxyapatite (HA) ceramic to enhance wear resistance by forming a solid lubricating tribofilm. CCM, CCM-3Cu, CCM-3Cu-1HA, and CCM-3Cu-2HA were processed using a laser-based directed energy deposition (L-DED) additive manufacturing (AM) technique. Antibacterial efficacy was evaluated using Pseudomonas aeruginosa, a Gram-negative bacterium, over 48 and 72 h. An extensive tribocorrosion study was conducted in physiologically relevant Dulbecco's Modified Eagle Medium (DMEM) at loads of 5 and 10 N, accompanied by microstructural analysis. Copper exhibits enhanced bacterial resistance, and the addition of HA improves wear resistance while also decreasing cobalt ion release. The wear resistance of CCM-3Cu-2HA showed a 6-fold improvement compared to CCM. These results indicate that HA-reinforced CCM-3Cu alloys are promising for the articulating surfaces of load-bearing implants.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"104 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144684065","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review introduces aptamer-modified nanozymes, receptor (cyclodextrins)- or ligand (amino acids, peptides)-functionalized catalytic nanoparticles, and molecularly imprinted polymer-coated nanozymes as hybrid frameworks improving the catalytic properties and selective/chiroselective functions of the nanozymes. Binding of the reaction substrates to the aptamers, ligands, or molecular-imprinted sites, by affinity interactions, concentrates the substrates in spatial proximity to the nanozyme catalytic sites (\"molarity effect\"), thereby enhancing the catalytic performance of the frameworks. Specific and chiroselective binding interactions of the substrates to the surface modifiers lead to selective or chiroselective chemical transformations. Moreover, by appropriate molecular engineering of the surface modifiers on the nanozymes, catalytic functions lacking in the parent bare nanozymes are demonstrated. Potential applications of surface-modified nanozymes are discussed.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"25 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144684314","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, single-walled carbon nanotubes (SWCNTs) are monodispersed in N-methylpyrrolidone (NMP) via surface modification, leveraging the spatial site-barrier effect of dispersant molecules and electrostatic repulsion. The monodispersed SWCNTs form a three-dimensional conductive network, significantly enhancing TNO's conductivity. Binder-free and self-supporting active electrodes are achievable due to the mechanical properties of SWCNTs. Moreover, V3+-doped mesoporous microsphere TNO exhibits a larger specific surface area and an increased number of oxygen vacancies, resulting in a substantial improvement in electrical conductivity. The binder-free electrode maintains a specific capacity of 243.99 mAh g-1 at 5C after 2000 cycles. The LFP-SS//3V-SWCNT5-SS full cell demonstrates a specific capacity of 115.36 mAh g-1 at 0.5C after 180 cycles, and the capacity remains 196.75 mAh g-1 at 2C after 200 cycles. The assembled LFP-SS//3V-SWCNT5-SS full cell delivers a specific capacity of 115.36 mAh g-1 at 0.5C following 180 cycles. In summary, this study presents a method to enhance the material conductivity through the integration of both internal and external modifications, thereby facilitating the application of lithium-ion batteries (LIBs) in wearable electronics.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":" ","pages":"41923-41935"},"PeriodicalIF":8.3,"publicationDate":"2025-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144598877","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, effectively coordinating the multistep processes in alkaline solutions, including water dissociation, hydroxyl desorption, and hydrogen generation, remains a critical challenge. This work develops a three-dimensional nanocomposite electrocatalyst composed of in situ-grown carbon nanotubes (CNTs), nickel nanoparticles encapsulated within them, and ruthenium nanoclusters on the surface. The catalyst synergistically facilitates water dissociation, hydroxyl transfer, and hydrogen adsorption, thereby achieving an ultralow overpotential (9.2 mV at 10 mA cm-2) for alkaline HER. Density functional theory reveals that CNTs facilitate electron transfer with minimal charge transfer resistance, while Ni nanoparticles within CNTs not only optimize the hydrogen adsorption of Ru but also facilitate the transformation of adsorbed hydroxyl (OHad) to OH-. These factors collectively facilitated the OHad + e- ⇌ OH- process, improving the kinetics of the HER. A solar-panel-powered electrolyzer equipped with this composite electrode achieves a low cell voltage of 1.41 V. This research provides valuable insights on designing Ru-based catalysts in practical alkaline HER applications.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":" ","pages":"42042-42051"},"PeriodicalIF":8.3,"publicationDate":"2025-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144606803","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
