Investigating the controlled diamond preparation from nanocarbon precursors with varying dimensionalities is crucial to optimize the transition conditions and even elucidate the daunting transformation mechanism, however, this remains outstanding challenge despite considerable effort. Herein, the imperative dimensionality effect of nanocarbon precursors on diamond synthesis and the physical mechanism under high temperature and high pressure is reported, by comparing the distinct transition processes of 0D carbon nanocages (CNCs) and 1D carbon nanotubes (CNTs) from conventional graphite. The optical and structural characterizations evidently demonstrate that both 0D CNCs and 1D CNTs first undergo collapse and graphitization, followed by the formation of mixed amorphous carbon with embedded diamond clusters, eventually leading to cubic diamond. The plotted pressure-temperature diagram exhibits the unique dimensionality effect of carbon nanomaterials to diamond transformation. These results provide valuable insights into the phase transition mechanisms of diamond synthesis and its derivatives under extreme conditions.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"20 1","pages":"e11137"},"PeriodicalIF":29.4,"publicationDate":"2025-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144769814","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Detailed characterization of the Mn2O3@GO-MoS2 composite revealed its tailored optical bandgap, crystal structure of the composite, and improved separation efficiency. The results showed that 98.85% degradation of TC was attained within 15 minutes. This high degradation performance occurred because of more TC adsorption onto the Mn2O3@GO-MoS2 composite surface, low bandgap energy, low recombination rate, and relocation of light absorption into the visible range. The H2 production rate using Mn2O3@GO-MoS2 compose was 14.55 mmol.g−1.h−1. Stronger visible light consumption through a tunable band gap (1.34 eV) and lower electron-hole (e–/h+) pair recombination are the primary causes of the extraordinary catalytic activity. The primary reactive species responsible for TC degradation are h⁺ and •O2⁻. Key intermediates and the degradation pathway are predicted by the HRMS analysis. A minor reduction of 9.5% in TC degradation efficiency after five successful cycles indicates that the composite is stable and reproducible. The important advantages of Mn2O3@GO-MoS2 composite are it can easily recoverable from the solution and their phenomenal reusability of six cycles for H2 production. This work presents a straightforward, economical, and eco-friendly method for fabricating highly reusable Mn2O3@GO-MoS2 composite aimed at treating TC and producing green H2.","PeriodicalId":82,"journal":{"name":"Journal of Materials Chemistry A","volume":"725 1","pages":""},"PeriodicalIF":11.9,"publicationDate":"2025-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144769927","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}

Furthermore, the patient's sensory impairment regarding the dangerous state of the wound and non‐visualization increases the difficulty and economic burden of wound care. To address these challenges, an electromagnetic induction‐powered electroactive dressing is developed that enables wireless electrical stimulation therapy and wound microenvironment monitoring. Interestingly, the formed nano‐interlocking structure between Ti<jats:sub>3</jats:sub>C<jats:sub>2</jats:sub>T<jats:sub>x</jats:sub> MXene and polycaprolactone fibers endows the dressing with superior mechanical performance and stable conductivity (≈3.5 S·cm<jats:sup>−1</jats:sup>, 72.2% retention rate after 7‐day phosphate‐buffered saline immersion), effectively matching practical wound therapy. Under a rotating magnetic field, the dressing can generate wirelessly therapeutic microcurrents (10.8 µA) that activate pro‐healing pathways (calcium, transforming growth factor‐β [TGF‐β], phosphatidylinositol 3‐kinase/protein kinase B [PI3K‐AKT], peroxisome proliferators‐activated receptors [PPAR], Axon guidance, and wingless‐type [Wnt]) while suppressing inflammatory pathways (tumor necrosis factor [TNF] and nuclear factor‐κB [NF‐kappa B]). This dual regulation of cellular behavior and the immune microenvironment accelerates wound healing and nerve regeneration by ≈36.3% and 283.8%, respectively, compared to the control group. The prepared dressing can also monitor the wound's physiological parameters, including temperature, strain, and exudate, enabling timeous and precise wound care. In short, this research promotes the development of electromagnetic induction biomedicine and personalized medicine.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"30 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144769947","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Neutrophil extracellular traps (NETs) drive liver metastasis by activating tumor cells and inducing immunosuppression. Targeted inhibition of peptidylarginine deiminase type 4 (PAD4), a key enzyme for NET formation, can disrupt this pro‐metastatic cascade. To address inefficient delivery of the PAD4 inhibitor GSK484, a neutrophil‐targeting nanoplatform (TPG: tFNA‐Ac‐PGP@GSK484) loaded with GSK484 is engineered by conjugating tetrahedral framework nucleic acids (tFNAs) with the neutrophil‐targeting peptide Ac‐PGP. Molecular docking and dynamics simulations confirm stable binding of GSK484 to tFNAs. In vitro, TPG suppresses reactive oxygen species and NETosis markers prominently, attenuating NET‐driven tumor proliferation, migration, invasion, and immune evasion. In vivo, TPG reduces primary tumor volume and liver metastasis markedly, extending the median survival days of the treated mice. These findings establish TPG as a dual‐action nanotherapy that blocks NETosis at its source and remodels the tumor microenvironment, providing a targeted strategy against primary tumors and liver metastatic dissemination.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"148 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144769954","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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 work, poly(vinylimidazolium) membranes functionalized with long alkyl side chains that self‐assemble into well‐defined microphase‐separated morphologies stabilized by hydrophobic and electrostatic interactions are reported. These unique structures localize the charge density along the polymer backbone to promote fast and selective ion transport. As a result, these membranes exhibit ionic conductivities and counter‐ion diffusivities surpassing those of conventional homogeneous membranes, along with unprecedented counter‐ion/co‐ion selectivity and proton‐blocking ability. These results establish a new design paradigm for high‐performance, phase separated charged polymer membranes that overcome the limitations of homogeneous membranes, with broad implications for advanced electrochemical technologies.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"13 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144769955","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recently, 2D MXenes-based nano-adsorbents demonstrated enormous potential in developing sustainable wastewater remediation technologies. This is owing to MXene’s tunable physicochemical attributes, which include high negative zeta potential, large specific surface area, exceptional adsorption capabilities, significant electric and thermal conductivities, hydrophilicity, and abundant surface chemistry. Besides, the innovations in strategic optimization of MXenes, including interlayer-space defect, surface, stochiometric, morphology and band-gap engineering, membrane preparation, hybridization and functionalization, have improved their adsorptive efficacies and dye-removal capacities, aiding effective wastewater treatment. This detailed review highlights the latest advancements in strategically MXene-based nano-adsorbent engineering and their integration as crucial vectors in wastewater treatment strategies through efficient dye removal from efflux. It provides a fundamental insight of the interaction between different dyes and MXenes-nanosystems to understand the dye removal mechanism.
