At the basis of the use of NDs as quantum sensors are nitrogen-vacancy center lattice defects, whose electronic structures are influenced by the surrounding environment and can be probed by the optically detected magnetic resonance technique. Ideally, limiting the NDs’ size as much as possible is important to ensure higher biocompatibility and provide higher spatial resolution. However, size reduction typically worsens the NDs’ sensing properties. This study endeavors to obtain sub-100 nm NDs suitable to be used as quantum sensors. Thermal processing and surface oxidations were performed to purify NDs and control their surface chemistry and size. Ion irradiation techniques were also employed to increase the concentration of the nitrogen-vacancy centers. The impact of these processes was explored in terms of surface chemistry (diffuse reflectance infrared Fourier transform spectroscopy), structural and optical properties (Raman and photoluminescence spectroscopy), dimension variation (atomic force microscopy measurements), and optically detected magnetic resonance temperature sensitivity. Our results demonstrate how surface optimization and defect density enhancement can reduce the detrimental impact of size reduction, opening to the possibility of minimally invasive high-performance sensing of physical quantities in biological environments with nanoscale spatial resolution.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"87 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143736478","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}

Despite significant advances in current sequencing technologies, the ability to identify subtle changes in natural and chemically modified nucleotides is hindered by structural and configurational complexity. Given the critical role of nucleobase modifications in data storage and personalized medicine, we propose a computational approach using a graphene nanopore coupled with machine learning (ML) to simultaneously recognize both natural and chemically modified nucleotides, exploring a wide range of modifications in the nucleobase, sugar, and phosphate moieties while investigating quantum transport mechanisms to uncover distinct molecular signatures and detailed electronic and orbital insights of the nucleotides. Integrating with the best-fitted model, the graphene nanopore achieves a good classification accuracy of up to 96% for each natural, chemically modified, purine, and pyrimidine nucleotide.

However, the detrimental role of the advanced glycation end-products (AGEs)-reactive oxygen species (ROS) cycle in impeding wound repair remains underexplored. To disrupt this pathological cycle, zeolitic imidazolate framework-8 (ZIF-8) encapsulated cerium dioxide (CeO₂) and adsorbed glucose oxidase (GOx) nanozyme particles ((ZIF-8@CeO₂)@GOx, zcg) were loaded into a methacrylic anhydride-modified gelatin (GelMA) hydrogel to form a sprayable dressing, zcg/GelMA (zcgG). Physicochemical characterization revealed that GOx catalyzes glucose oxidation, triggering ZIF-8 acid-mediated decomposition to release zinc ions and CeO₂ nanoparticles, thereby enabling a cascade of glucose depletion, antioxidant, and antiglycation functions. In vitro antimicrobial and cytotoxicity experiments optimized the zcg concentration in GelMA. Under oxidative and hyperglycemic culture conditions, we validated the zcg mechanism of blocking the AGEs-ROS cycle, restoring fibroblast mitochondrial membrane potential, and subsequently suppressing cellular senescence. In a bacterial-infected diabetic rat skin wound model, the zcgG group demonstrated substantially reduced inflammatory levels, a 68% decrease in AGEs, and a 1.9-fold increase in collagen deposition compared to blank controls. Within 2 weeks, the zcgG group achieved complete wound closure, while the control group retained 28% of the initial wound area. This work provides preliminary evidence for the feasibility of using cascade nanozymes to break the AGEs-ROS cycle and promote wound healing.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"9 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143734298","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, developing adsorbents with high selectivity and productivity for C₂H₄/C₃H₆ remains a significant challenge and an urgent necessity. In this study, a porphyrinyl metal–organic framework (MOF), Al-TCPP, was developed for the simultaneous recovery of C₃H₆ and C₂H₄ through a one-step adsorption–desorption process. Benefiting from its well-developed microporous structure and abundant N- and O-accessible sites, Al-TCPP demonstrated exceptional adsorption capacities and selectivity for C₃H₆ and ethane (C₂H₆) over C₂H₄ under ambient conditions. The adsorption capacities (in cm³·g^–1) reached 162.4 for C₃H₆ and 118.5 for C₂H₆ at 298 K and 100 kPa. The ideal adsorbed solution theory (IAST) selectivity values for C₃H₆/C₂H₄ and C₂H₆/C₂H₄ were 10.1 and 1.8, respectively. Thermodynamic studies and theoretical calculations revealed stronger interactions between C₂H₆ and C₃H₆ molecules with the Al-TCPP framework than with C₂H₄. Systematic breakthrough experiments demonstrated outstanding separation performance for binary C₂H₆/C₂H₄ and C₃H₆/C₂H₄ mixtures, as well as ternary C₃H₆/C₂H₆/C₂H₄ mixtures, achieving record productivities of 150.2 and 86.5 L·kg^–1 for polymer-grade C₂H₄ (≥99.9%) and C₃H₆ (≥99.5%), respectively. Notably, the separation performance remained stable under variable flow rates, temperatures, humidities, and multiple adsorption–desorption cycles. Overall, this study highlighted Al-TCPP as a highly competitive adsorbent for addressing the challenges in MTO product separation. Moreover, it offered valuable insights into the design of MOFs with heteroatom-rich accessible sites for efficient separation of low-carbon hydrocarbons.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"23 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143734295","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, these materials suffer from structural instability, which becomes increasingly severe as the nickel content rises. Despite their significant importance, the intrinsic structural change mechanisms of nickel-rich cathodes, especially at practical cycling rates, remain unclear. This study investigates the influence of nickel content and cycling rate on the phase behavior and electrochemical performance of three representative nickel-rich cathode materials: LiNi_0.83Mn_0.05Co_0.12O₂ (Ni-83), LiNi_0.90Mn_0.05Co_0.05O₂ (Ni-90), and LiNiO₂ (Ni-100). Using synchrotron <i>operando</i> X-ray diffraction alongside electrochemical analysis, we have elucidated distinct structural transformation mechanisms: a solid-solution process for Ni-83, a quasi-two-phase mechanism for Ni-90, and classic H1-M–H2-H3 phase transitions at slow rates for Ni-100. Our findings highlight significant rate-dependent behaviors which affect these materials’ electrochemical performance and stability under practical conditions. Notably, high cycling rates impede the H2–H3 transition in Ni-100 due to substantial lattice contraction, emphasizing the need for optimizing nickel content to enhance the stability and performance of high-nickel cathodes for next-generation lithium-ion batteries.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"53 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143734291","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}

Herein, a LiMn₂O₄ covered by LiTaO₃ featuring as a fast-ion conductivity was synthesized and employed as a rocking-chair lithium-ion-capacitor cathode materials. As a result, the 3TaLMO with the optimal coating thickness displayed low impedance, the highest lithium-ion diffusion rate, and excellent cycling stability (half-cell, 80.90% capacity retention rate after 2000 cycles, at 0.3 A g^–1). After further assembly into rocking-chair lithium-ion capacitor (LIC) with activated carbon, it achieves a high energy density (394.5 W h kg^–1), high power density (90 kW kg^–1), and an excellent long cycle life (77.27% of the initial capacity after 2000 cycles at 1.0 A g^–1). The excellent electrochemical performance is mainly attributed to the excellent structural stability and fast-ion transfer characteristics of this coating composite structure.

The coal-based derived carbon support with tunable structure, elemental composition, defects, and special surface area controlled by a proposed two-step coking-activation strategy, in which special scale-like or alveolate structures were obtained. It was demonstrated by characterization that the structure and defect of the carbon support affect the carburization behavior of iron species, and then the highest Fe₅C₂ content was found on FeK@AC-2.0-750 catalyst.

The results indicate that Mo barrier layers with a thickness of approximately 0.5 nm at different interfaces perform different functions. The Mo barriers at Al-on-Sc interfaces primarily play a role in suppressing the columnar crystallization of Al layers, contributing to the smoothening of interfacial roughness. The thin Mo layers at Sc-on-Al interfaces mainly act as antidiffusion barriers, preventing the diffusion of Al atoms into Sc layers.
