Existing SAFs are plastic fibers that can only be used once, are nonrecyclable, and lack damage tolerance. 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. The dynamic nature of these nanodomains allows for complete recyclability of PU–PCL70 through respinning.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"7 6","pages":"2328–2336 2328–2336"},"PeriodicalIF":9.6,"publicationDate":"2025-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144189156","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 synthesized hierarchical CuCo2O4 nanodendrites (NDs) composed of ultrathin nanosheet subunits with a spinel structure via a simple coprecipitation method followed by annealing. This spinel framework features well-defined Cu–Co pairs. In an alkaline solution, CuCo2O4 NDs achieve a high Faradaic efficiency (97.86%) and an impressive NH3 yield (34.23 mg h–1 mgcat–1) at −0.3 V for NO3RR, accompanied by excellent stability. These properties arise from the synergistic effect of Cu–Co pairs and the two-dimensional architecture. When applied in a CuCo2O4 NDs||CuCo2O4 NDs electrolyzer, the HzOR-assisted NO3RR operates at 0.997 V (10 mA cm–2), which is 573 mV lower than the conventional NO3RR system with oxygen evolution.

Here, we first systematically review the primary strategies for deploying nanoparticles in the brain, with a particular focus on minimally invasive and precise deployment approaches that leverage external physical field interventions to overcome the blood-brain barrier. Next, we critically summarize the key physical factors governing nanoparticle transport across the blood-brain barrier. Additionally, we outline nanoparticle clearance pathways in the brain and discuss the primary determinants influencing nanoparticle fate. Finally, we outline outstanding challenges and propose future research directions toward reliable, highly controllable nanoparticle deployment within the nervous system.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"7 6","pages":"2288–2309 2288–2309"},"PeriodicalIF":9.6,"publicationDate":"2025-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144189244","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, relying on novel dynamic carbon–sulfur (C–S) bonds and available bismaleimide (BMI) resins, a high performance BMI vitrimer is reported. From one-pot synthesis, this BMI vitrimer exhibits exceptional thermal and physical properties with a typical Tg of ∼ 131 °C, storage modulus of 3.1 GPa, tensile strength of 80.4 MPa, and elongation of 12.2%, along with outstanding solvent resistance. Moreover, because of the exchangeable C–S bonds that are confirmed by model reactions, the BMI vitrimer possesses thermally-triggered malleability that is identified from stress–relaxation, creep deformation, and multireshaping investigations. Meanwhile, the BMI vitrimer can be selectively degraded by thiol compounds and achieve closed-loop recycling. This study will provide a convenient platform for the development of sustainable thermosets with high performance.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"7 6","pages":"2281–2287 2281–2287"},"PeriodicalIF":9.6,"publicationDate":"2025-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144189133","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}

Therefore, we carried out a systematic study on the influence of various experimental parameters on the effective electronic conductivity of CAM pellets. These parameters are applied stack pressure, Ni content of CAM, CAM particle morphology, particle coating, and heat treatment. Pellets of fully lithiated and uncoated Ni-rich NMC particles reach effective electronic conductivities σeoneff in the range of 10–1 S/cm at high pressures and 10–2 S/cm at low pressures. Particle coating by LiNbO3 lowers σeoneff by half an order to 1 order of magnitude. While heat treatment at 900 °C is capable of removing surface impurities on the CAM particle, it also leads to increased Li/Ni disorder in the bulk of the particles.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"7 6","pages":"2262–2269 2262–2269"},"PeriodicalIF":9.6,"publicationDate":"2025-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.acs.org/doi/epdf/10.1021/acsmaterialslett.4c02595","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144189259","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Metal–organic frameworks (MOFs), a tunable class of crystalline porous materials, are promising candidates for atmospheric water harvesting. The channel-pore MOF STA-16(Co) stands out due to its robust phosphonate-based structure, which provides high stability and excellent water uptake. However, STA-16(Co) suffers from slow water uptake kinetics. To address this limitation, we introduced defects into STA-16(Co) by selectively removing linkers through treatment with nitrilotriacetic acid, significantly improving water diffusion kinetics. The defective MOFs demonstrate markedly faster water saturation rates─delivering ∼50% more water in a 40 min cycle─while maintaining the same uptake capacity and isothermal behavior as pristine STA-16(Co). Solid-state nuclear magnetic resonance analysis confirms that localized defects enhance efficiency without altering the overall pore geometry. This study presents a straightforward and generalizable strategy to optimize water sorption in channel-based MOFs.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"7 6","pages":"2255–2261 2255–2261"},"PeriodicalIF":9.6,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144189187","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}

Engineering the chain extender and/or modifying the hard domain are popular strategies for reinforcing TPU elastomers. Here, a strategy based on the thermodynamic principle that the tensile force is strongly related to the Helmholtz free energy for a system with constant temperature and volume is proposed to modify the TPU mechanical performance. The constructed cocontinuous morphology confers to it the highest strength (61.0 MPa) and toughness (156.2 MJ/m3), amounting to 35.3-fold and 11.9-fold improvements, respectively, compared to TPUs constructed with the homogeneous morphology. The significant orientation of morphology during stretching raises the interfacial free energy, which is an analogous mechanism resulting in a higher internal energy. Additionally, this reinforcement technique is scalable, reproducible, and cost-effective and also enriches the fundamental understanding of polymer mechanics.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"7 6","pages":"2238–2245 2238–2245"},"PeriodicalIF":9.6,"publicationDate":"2025-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144189180","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}
