The investigation of the CO2RR of APGNCs with a surface single-atom difference remains challenging. Herein, the successive addition of a surface sulfur atom (μ4-S) on Au60 was concurrently realized via a modified ligand exchange. The additional μ4-S makes the outer three kernel gold atoms in situ transform into staple gold atoms without altering other parts, endowing them with optimal model catalysts. Notably, Au60S6 exhibited high activity and CO selectivity over 95% within the entire test potentials, which decreased with the introduction of a μ4-S. DFT simulations indicate that the d-band center of the gold active site upshifts toward the Fermi level with the addition of a μ4-S, which strengthens the adsorption of intermediates, raises the energy barriers for CO desorption. This work provides an unprecedented paradigm for understanding structure–property relationships at the level of a surface single atom.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"7 6","pages":"2366–2373 2366–2373"},"PeriodicalIF":9.6,"publicationDate":"2025-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144189144","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}

Its high catalytic activity was experimentally confirmed, attributed to the in situ MoWC2/Mo2C heterostructure during sintering. What’s more, the produced electrode exhibits both high aerophobicity and high hydrophilicity. The overpotentials of the electrode of 1500 mA·cm–2 in 0.5 M H2SO4 and 1.0 M KOH were 352 and 276 mV, respectively, better than those of the Pt-wire electrode. The chronopotentiometry curves of 10–1500 mA·cm–2 confirmed its long-term stability.

Traditional TIMs require extreme compliance for low thermal contact resistance (Rc), resulting in the challenge of achieving both a high modulus and a low Rc. Here, we report a resilient (>96%) thermally conductive elastomer with a high elastic modulus (12.3 MPa) and a low Rc (12.3 K mm2 W–1) based on a dynamic/nondynamic hybrid cross-linking network strategy. The nondynamic cross-linking network serves as the backbone of the elastomer, providing elasticity and robustness, while the dynamic cross-linking network with dynamic features offers partial solid-state plasticity to reduce the Rc between the elastomer and the rigid substrate. Use of the thermally conductive elastomer as the TIM in chip cooling demonstrated superior heat dissipation capability, resulting in an 11 °C reduction in the chip temperature compared with that obtained with the commercial TIM. This work provides an effective strategy for balancing the Rc and modulus, broadening the application range of TIMs.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"7 6","pages":"2133–2141 2133–2141"},"PeriodicalIF":9.6,"publicationDate":"2025-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144189097","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}

Addressing this gap, we present an approach involving the development of 3D embedded, invisible Raman codes with chemical vibrations employing 3D-printable triple-bonded nanoparticles. These colorless triple-bonded nanoparticles, characterized by the distinct and stable spectral features of spontaneous Raman scattering, ensure high transparency, durability, and coding capacity. By embedding multiple, visually undetectable Raman-based QR codes within the internal structure of 3D printed objects, rather than using visible measures on 2D surfaces, our multilayered encryption system significantly enhances the information security by invalidating single-layer decoding attempts and requiring the combination of multiple layers to decrypt the embedded information.

Benefiting from ligand-to-metal charge transfer, 1-Ce demonstrates good visible light absorption. Additionally, the chelating coordination of nitrogen and oxygen atoms endows 1-Ce with excellent chemical stability. Owing to its abundant metal sites, high porosity, and visible light responsiveness, 1-Ce exhibits outstanding photocatalytic activity for CO2 reduction under visible light, achieving a CO production rate of 138 μmol·g–1·h–1─surpassing previously reported Ce-MOF photocatalysts.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"7 6","pages":"2337–2342 2337–2342"},"PeriodicalIF":9.6,"publicationDate":"2025-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144189083","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}

Molecular dynamics simulations revealed that the self-assembled hierarchical structures arise from the C–CNT aggregation. The use of high-temperature-resistant epoxy resin enhances adhesion, environmental resistance, and mechanical durability. The coatings maintained high solar absorptance and structural integrity under extreme thermal cycling and water flushing. In addition, we demonstrated that the coatings have excellent photothermal conversion efficiency, significantly raising the temperature of coated silk textiles under low solar irradiation and increasing the voltage output of thermoelectric devices by four times compared with uncoated ones. This scalable, efficient fabrication method requires no extra materials or complicated steps, demonstrating broad potential for solar energy and thermal management.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"7 6","pages":"2352–2359 2352–2359"},"PeriodicalIF":9.6,"publicationDate":"2025-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144189084","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}

Herein, we fabricate recyclable, mechanically robust elastic SAFs with exceptional damage tolerance via wet spinning of multiblock polyurethane (PU) composed of polycaprolactone (PCL) and polytetrahydrofuran (PTMG) segments. The SAFs are denoted as PU–PCL70, achieving an ultrahigh true strength of 908.8 MPa, a high damping efficiency of 87%, and a record fracture energy of 4042 kJ m–2. Mechanistic analysis reveals that the superior performance of PU–PCL70 originated from the oriented hierarchical phase-separated nanodomains formed by hydrogen and coordination bonds and rigid PCL segments. These rigid nanodomains are capable of deformation and disintegration to effectively absorb energy. These nanodomains can autonomously re-form, enabling the fibers with reusability without treatment.
