In this study, we have synthesized three-dimensional (3D) porous composites comprising V<sub>2</sub>O<sub>3</sub> nanoparticles embedded in <em>Juncus effusus</em> cellulose-derived carbon aerogels (VCA) using a self-templating method followed by high-temperature pyrolysis. The V<sub>2</sub>O<sub>3</sub> nanoparticles possess a 3D V-V framework and a relatively narrow bandgap, facilitating the Mott transition for enhanced conductivity. Furthermore, their uniform dispersion on hollow carbon tubes of <em>Juncus effusus</em> promotes efficient electron transfer and creates numerous heterogeneous interfaces. Consequently, VCA-2 demonstrates outstanding EMWA performance, achieving a minimum reflection loss of −63.92 dB at a matching thickness of 2.0 mm and a maximum effective absorption bandwidth of 8.24 GHz at a thickness of 2.44 mm, covering nearly half of the tested frequency range. Additionally, the radar cross-section reduction reaches a peak value of 29.40 dB m<sup>2</sup>, underscoring the excellent radar stealth capabilities of the material. In summary, VCA exhibits exceptional EMWA, radar stealth, and thermal insulation properties, highlighting its potential for multifunctional applications in EMWA material development.</div></div>","PeriodicalId":10088,"journal":{"name":"Chinese Chemical Letters","volume":"36 7","pages":"Article 111065"},"PeriodicalIF":9.4,"publicationDate":"2025-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143934734","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Skin protein damage or modifications such as glycation, carbonylation or oxidation, have a significant impact on its function, therefore directly influencing various skin functions or properties including skin appearance.

In this article, we present a three-channel imaging approach to simultaneously visualize and quantitatively evaluate protein oxidation, protein glycation and carbonylation in a full-thickness skin model. We successfully visualized and quantified the impact of the multiple stimuli (ultraviolet radiation A (UVA) and/or methylglyoxal) as well as treatment effect of positive control (vitamins C and E) with this method. Our findings indicate that multiple stimuli exhibit synergistic effects on protein damage. Furthermore, we evaluated a unique combination of skin care ingredients which demonstrated an excellent efficacy in resisting protein damage. Further research revealed that three ingredients of the combination upregulate autophagy in cells, which may contribute to remove damaged proteins and maintain protein quality homeostasis. This method provides a holistic assessment of protein damages and can be employed to evaluate the impact of various stimuli or to assess the efficacy of skin care ingredients in mitigating such damage.</div></div>","PeriodicalId":10088,"journal":{"name":"Chinese Chemical Letters","volume":"36 6","pages":"Article 111182"},"PeriodicalIF":9.4,"publicationDate":"2025-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143845134","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
