NIR-II Responsive Platinum-Engineered Vanadium Carbide MXene Endows Poly-L-Lactic Acid Bone Scaffold with Photothermal Antibacterial Property

Published on 2026-01-30 by Lin Sun, Zihao Zhang, Bingxin Sun, Zhiheng Yu, Guoyong Wang @MDPI

Abstract: Vanadium carbide (V2C) MXene shows great potential for addressing challenging implant-associated infections in bone regeneration due to its strong photothermal conversion efficiency. However, its photothermal efficacy is restricted to the near-infrared I (NIR-I) region due to a limited absorption range. To address this, we designed platinum nanoparticle-decorated V2C heterostructures (Pt@V2C) via an in situ growth method, leveraging Pt&amp;rsquo;s plasmonic and catalytic properties to extend[...]


Our summary: The study presents platinum-decorated vanadium carbide MXene heterostructures that extend photothermal efficacy to the NIR-II region. These structures are integrated into poly-L-lactic acid scaffolds, achieving high photothermal conversion efficiency and significant antibacterial effects. The scaffolds demonstrate biocompatibility and support tissue regeneration, offering a promising solution for implant-associated infections.

Preparation and High-Sensitivity Thermochromic Performance of MXene-Enhanced Cholesteric Liquid Crystal Microcapsule Textiles

Published on 2026-01-15 by Xuzhi Sun, Yi Yang, Xiangwu Zhang, Maoli Yin, Mingfei Sheng @MDPI

Abstract: To mitigate the attenuation of color-change sensitivity in cholesteric liquid crystals (CLCs) post-microencapsulation, this study developed MXene-reinforced thermochromic textiles. Monolayer/few-layer MXene nanosheets were fabricated via an etching-intercalation-dispersion approach, while cholesteric liquid crystal microcapsules (CLCMs) were synthesized through a solvent evaporation method. Cotton fabrics were pretreated with polydopamine (PDA), followed by the fabrication of poly(diallyldimethy[...]


Our summary: This study presents MXene-enhanced cholesteric liquid crystal microcapsules to improve color-change sensitivity in textiles. Monolayer MXene nanosheets and cholesteric liquid crystal microcapsules were synthesized using specific methods. The resulting textiles demonstrated reversible color transitions and excellent hydrophobic properties, addressing limitations in conventional microencapsulated systems.

Abstract: A first-principles investigation was conducted to characterize the novel Cr2ZnC MAX phase and its exfoliated MXene nanosheet, Cr2C. The study critically examines the effect of electron correlations on the bulk phase, revealing that the PBE+U framework, unlike standard PBE, yields a dramatically enhanced magnetic moment of 12.80 &amp;mu;B (vs. 1.88 &amp;mu;B), confirming the necessity of this approach for Cr-based carbides. The phase stability is confirmed through rigorous analysis of its[...]
