To this end, recent work has introduced the concept of MOF modifiers, i.e., the mixing of a modifier agent with a MOF crystal to lower the MOF's melting temperature. While previous work has focused on hybrid modifiers, we here investigate the use of inorganic ammonium halide salts as modifiers for zeolitic imidazolate frameworks (ZIFs). We show that co-melting various ZIF crystals with the halide salt significantly lowers both melting and glass transition temperatures, enabling fabrication of centimeter-sized hybrid glasses and melt-processing of ZIF-8, which otherwise decomposes before melting. In situ X‑ray imaging is used to visualize that the molten halide salts infiltrate the ZIF crystals and ultimately promote the collapse of the crystalline domains into a homogeneous melt. X-ray pair distribution function analyses confirm the disruption of the Zn─N coordination network and formation of Zn─X (X = Cl, Br, and I) bonding, thus lowering the framework connectivity. Our findings broaden the scope of modified MOF glasses and offer a versatile route for tailoring their thermal processing and network structure.","PeriodicalId":228,"journal":{"name":"Small","volume":" ","pages":"e73675"},"PeriodicalIF":12.1,"publicationDate":"2026-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147831448","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}

Yet, atomically thin amorphous van der Waals nanosheets with reproducible device-level properties remain largely unexplored. Here, we report an electrochemical exfoliation strategy that directly converts single-crystal TaIrTe4 into amorphous nanosheets with average lateral dimensions exceeding 50 µm, thickness down to 2 nm, and high ambient stability. Structural amorphization induces a metallic-to-semiconducting transition accompanied by bandgap opening and the formation of distributed trap states, as supported by density functional theory. Field-effect transistors fabricated from these nanosheets exhibit ambipolar transport with on/off ratios above 103 and mobilities of ∼1.5 cm2 V-1 s-1, enabling sensitive electrical readout. Upon optical stimulation, the devices generate self-powered, persistent photocurrents. Wavelength-selective excitation between 405 nm and 638 nm produces reversible conductance potentiation and depression, realizing fully optical and bidirectional synaptic plasticity with ultralow energy consumption (< 5.65 pJ per pulse). Neuromorphic network simulations incorporating the experimentally extracted dynamics achieve 92.1% on the MNIST dataset. These results demonstrate a scalable platform for producing amorphous vdW nanosheets and show that crystalline-to-amorphous conversion enables light-programmable signal processing and energy-efficient intelligent hardware.","PeriodicalId":228,"journal":{"name":"Small","volume":" ","pages":"e73719"},"PeriodicalIF":12.1,"publicationDate":"2026-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147831573","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}

A porous PbI2 scaffold enhances organic salt diffusion, ensuring complete conversion to high-quality perovskite films with larger grains, improved crystallinity, and lower trap densities. This consistently yields PSCs with efficiencies >25%-26% and outstanding stability, often retaining >90% performance after thousands of hours.

However, the irreversible lattice distortion caused by Fe4+ and Mn3+ Jahn-Teller (J-T) effect during electrochemical cycling leads to severe voltage hysteresis, continuous voltage decay, and structural degradation upon extensive cycling, thereby compromising energy efficiency and life-span. In this work, trace amounts of scandium are introduced into the transition-metal layers to modulate the local electronic structure and coordination environment. The strong Sc-O ionic bonding enhances TM-O covalency, reduces the geometric symmetry of the ligand field, and eliminates the 3d orbital degeneracy of Fe and Mn ions, thereby suppressing the J-T distortions of Fe4+O6 and Mn3+O6 octahedra. Benefitting from the stable structure, the resultant Na0.67Fe0.49Mn0.5Sc0.01O2 (NFMO-Sc) exhibits small voltage hysteresis and voltage decay, as well as remarkable long-cycling stability.

This work fabricates a novel thermal-insulation and radiation-modulation integrated infrared stealth material, integrating polyimide (PI) aerogel fibers (endowed with thermal insulation) and MXene/tannic acid (TA) composite (featuring low emissivity and oxidation resistance), to achieve thermal camouflage for high-temperature targets. In this composite system, the abundant pores within PI aerogel fibers not only suppress gas convective heat transfer but also extend the heat conduction path along the pore walls, thus achieving efficient thermal insulation. Meanwhile, MXene's metallic-like conductivity and layered structure enable it to efficiently reflect infrared thermal radiation, minimizing radiant heat loss to the surroundings. Consequently, the composite PI/SA/TM exhibits a low thermal conductivity of 0.084 W·m-1·K-1 and a low emissivity of 0.17. At an ambient temperature of 200 °C, its radiant temperature is merely 40.7 °C, outperforming pure PI, TM film and commercial fabrics in terms of stealth performance. The incorporation of TA further enhances oxidation stability for PI/SA/TM, retaining excellent emissivity (0.24) even after 15 days of humid heat aging.

The patch operates autonomously through a feedback loop: upon detection of elevated wound temperature resulting from infection-induced excessive inflammation, the non-antibiotic PDT modality is triggered to effectively eradicate drug-resistant bacteria. Subsequently, ES is activated to promote cellular proliferation and migration during the prolonged healing process. This multifunctional patch exhibited potent antibiotic-free antibacterial efficacy toward typical drug-resistant bacteria (methicillin-resistant Staphylococcus aureus) and significantly accelerated burn wound healing in both in vitro and in vivo models.

Coating films are fabricated through a simple painting process that avoids hot-pressing, thereby enabling straightforward application in practical coatings. The UV-induced aggregates significantly broaden the visible-light excitation range: in addition to violet, blue, and white light, the RTP material can be excited by green light at 520 nm, displaying a phosphorescence lifetime (τPhos) of 70 ms and an afterglow duration (tag) of 12 s, outperforming previously reported green-light-excitable RTP systems. Under violet, blue, or white light excitation, Cor and its aggregates achieve a maximum τPhos of 6.20 s and a remarkable tag of up to 90 s, far exceeding the 40 s record of Cor-doped thermoplastic polymers. Furthermore, leveraging phosphorescence resonance energy transfer enables a red afterglow of 60 s under white-light excitation. Owing to the high glass transition temperature of the SER matrix, the material retains afterglow emission even at 135°C. These combined characteristics significantly expand the application scope of RTP materials.","PeriodicalId":228,"journal":{"name":"Small","volume":" ","pages":"e73676"},"PeriodicalIF":12.1,"publicationDate":"2026-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147831556","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}

Nicotinamide mononucleotide (NMN), a precursor to nicotinamide adenine dinucleotide (NAD), possesses antioxidant properties and neuroprotective potential. In this study, we investigated whether NMN mitigates Nano-Al2O3-induced cognitive impairment and neuronal injury, with a focus on ferroptosis-related pathways. Behavioral tests demonstrated that Nano-Al2O3 exposure impaired learning and memory in mice. Histological and ultrastructural analyses revealed hippocampal neuronal loss, reduced Nissl body density, and mitochondrial abnormalities, all of which were alleviated by NMN treatment. Nano-Al2O3 exposure also increased lipid peroxidation, malondialdehyde, Fe2+, and reactive oxygen species, while decreasing NAD+, glutathione (GSH), and glutathione peroxidase 4 (GPX4), indicating ferroptosis-related damage. NMN largely reversed these alterations, restored redox homeostasis, and improved cognitive performance. Collectively, these findings suggest that Nano-Al2O3-induced neurotoxicity is associated with dysregulation of the GSH/GPX4 axis and that NMN protects against cognitive impairment and neuronal injury, at least in part, by suppressing ferroptosis-related processes.
