However, coverage of ORR-product on catalytic sites leads to increase in cathode polarization, resulting in poor activity and cycleability of ORR catalyst. This work suggests an innovative strategy to bypass ORR-product (Li2O2) coverage through creating electrolyte storage spaces in carbon matrix to enhance Li+ ion transport in porous catalyst. Reaction of a lithiated porous carbon with water vapor or humidified CO2 can intercalate LiOH·H2O or Li2CO3 into the carbon matrix to expand the graphite interlayer space. Compared with the pristine catalyst, the interlayer-space-expanded catalysts demonstrate smaller polarization and higher activity toward ORR, presenting higher ORR capacity and better ORR-OER cycleability. The Co/NPC*FD obtained by treatment of the lithiated Co-deposited and N-doped carbon (after 10 lithiation-delithiation cycles) with humidified CO2, presents an ORR capacity as high as 15,700 mAh g-1 and an excellent cycleability of 140 cycles when ORR-OER cycling at current density of 160 mA g-1 and termination potential of 2.0 V vs. Li/Li+ under a cycling capacity of 1,000 mAh g-1. A power density as high as 1,700 mW g-1 has been achieved at the current density of 640 mA g-1. This work provides a paradigm-shifting approach to circumvent catalyst passivation in metal-air batteries. We anticipate it will accelerate the development of practical Li-O2 systems while offering generalizable strategies for related energy conversion technologies.","PeriodicalId":305,"journal":{"name":"Electrochimica Acta","volume":"27 1","pages":""},"PeriodicalIF":6.6,"publicationDate":"2025-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143931007","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pristine and grafted MOFs were assembled into cellulose nanofibers (CNF) for the preparation of functional CNF-based bionanocomposites. The mechanical properties of the films improved, with Young’s modulus increasing from 1.3 GPa in CNF to 7.5 GPa in the film with 20% MOF loading. The potential of the developed materials for photocatalytic antimicrobial therapy was evaluated against Staphylococcus aureus (S. aureus). In vitro tests showed that both bionanocomposite films with pristine and DBA-modified MOF remarkably reduced bacterial growth due to the photocatalytic action of the MOF under visible light. The inhibition values were around 58% and 72%, respectively, while minimal inhibition was observed under dark conditions.

A femtosecond laser was employed to fabricate 3 and 10 μm periodic linear (L3 and L10) and grid (G3 and G10) patterns on tetragonal zirconia polycrystal stabilized with 3% molar yttrium oxide (3Y-TZP). The patterns exhibited homogeneous, high-aspect-ratio structures with laser-induced nanotopography within the grooves while maintaining minimal surface damage. All patterns significantly enhanced human mesenchymal stem cell (hMSCs) adhesion, spreading, and migration through topographical guidance and nanotopography-induced cell anchoring. Pattern geometry influenced cell morphology and migration: linear patterns induced high elongation and alignment along the grooves, leading to unidirectional migration, while grid structures promoted widespread cells with bidirectional alignment, promoting bidirectional migration. Antibacterial assessment using Pseudomonas aeruginosa (P. aeruginosa) (Gram-negative) and Staphylococcus aureus (S. aureus) (Gram-positive) revealed a size-dependent bacterial response. The patterns of lower periodicity (L3 and G3) showed superior antibacterial properties, reducing bacterial colonization through distinct mechanisms: mechanical trapping for P. aeruginosa (25% reduction) and disruption of bacterial aggregation for S. aureus (30% reduction). Coculture experiments with hMSCs and bacteria confirmed that L3 and G3 surfaces effectively combined enhanced cell adhesion with reduced bacterial colonization, highlighting the potential of USP-DLIP for developing multifunctional cell-instructive and antibacterial biomaterial surfaces.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"78 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143931262","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, the long-chain oleic acid (OA) ligands on QDs’ surfaces during the preparation process impedes the efficient separation and transfer of photogenerated carriers, limiting their practical applications. To address this issue, we employed a solid-state ligand exchange technique, replacing OA with 3-mercaptopropionic acid (MPA) on the CsPbBr3 QDs. This substitution not only significantly reduces the grain spacing but also effectively passivates the surface defects, resulting in lower resistance and improved stability, which further facilitates effective carrier separation and transport. Under simulated sunlight irradiation, the MPA-CsPbBr3 QDs photoanode shows a photocurrent density of 4.23 mA cm–2 and operates stably underwater for a long period of time up to 11,600 s, showing remarkable durability. This performance is significantly better than currently reported CsPbBr3 QDs photoanode devices and far exceeds conventional CsPbBr3 thin film photoanodes.

The charge transport through peptides can be effectively modulated via intrinsic composition, structure, and, most notably, interfacial engineering. However, achieving specific electrical properties, such as solid-state rectification, remains a challenge in peptide-based bioelectronics. To fill this gap, a solid-state heterojunction is designed based on the uniform and densely-packed bilayers composed of peptide and quantum dots (QDs) self-assembled monolayer. The presence of a QDs monolayer markedly regulates the rectification and static dielectric constant (ɛr) of the peptide-based heterojunctions. The solid-state rectification ratio of peptide junctions can be raised up to ≈103, and the ɛr increases by a factor of 3. Both the rectification ratio and ɛr of peptide/QDs heterojunctions increase with enhanced non-covalent interactions between peptide side chains and QDs. The interfacial interaction modulates the coupling across the interface, influencing the energy level alignment at the peptide/QDs interface. This leads to distinct charge transport pathways under opposite bias polarities, thus achieving the regulation of rectification. These findings suggest that strengthening interfacial interactions can increase both rectification and ɛr. This deepens the understanding of interface-regulated molecular charge transport and offers a theoretical framework for optimizing the biomolecular solid-state rectification.","PeriodicalId":228,"journal":{"name":"Small","volume":"3 1","pages":"e2500346"},"PeriodicalIF":13.3,"publicationDate":"2025-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143932579","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, the high affinity of Sb element for oxygen makes InSb susceptible to native surface oxidation, a process that creates barriers to carrier transport and reduces light absorption efficiency, thereby significantly degrading the performance of InSb-based PDs. In this study, we propose a solution-based route for fabricating InSb nanowires (NWs) decorated with Au nanoparticles (NPs) to fabricate a broadband, self-driven PD. The incorporation of Au NPs significantly reduces the surface trap states introduced by surface native oxide layer and enhances the performance of the PD across the visible to near-infrared (NIR) region. Compared with bare InSb NWs PDs, the Au/InSb nanohybrid device achieves a dramatic improvement in the switching ratio, reaching approximately 300 under visible-to-NIR illumination at an intensity of 36 mW/cm2. The maximum responsivity and detectivity values of the Au/InSb nanohybrid PD were 100 times higher than those of bare InSb NWs. Finite-difference time-domain (FDTD) simulations were employed to analyze the spatial distribution of the electromagnetic field across Au/InSb nanohybrids. The localized surface plasmon resonance (LSPR) of Au NPs and the transfer of hot electrons were identified as key factors contributing to the observed performance enhancement. This study serves as a foundational exploration of the potential for high-performance PDs utilizing Au NPs and other narrow-band III-V materials exhibiting LSPR effects.","PeriodicalId":344,"journal":{"name":"Journal of Alloys and Compounds","volume":"28 2 1","pages":""},"PeriodicalIF":6.2,"publicationDate":"2025-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143932593","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}
