Van der Waals (vdW) ferroelectric field-effect transistors offer nonvolatile polarization control and a highly tunable semiconductor channel, enabling multilevel states and making them promising for brain-inspired electronics. Here, we present a reconfigurable bimodal ferroelectric synapse based on the CuInP2S6/hBN/WSe2 vdW heterostructure, extending beyond conventional single-modal synaptic devices by introducing added functionality. Transport measurements and piezoresponse force microscopy reveal precise electrical control over the ferroelectric domain landscape, enabling continuous tuning of WSe2 channel conductance and its threshold voltage. Crucially, the ambipolar nature of WSe2 allows for real-time switching between excitatory and inhibitory synaptic behaviors, mimicking multimodal neurotransmission observed in the human brain. Moreover, the bimodal synapse is demonstrated at channel lengths down to 50 nm, venturing into previously uncharted territory for ferroelectric vdW synapses. Neural network simulations incorporating our device show excellent learning performance for both synaptic modes, highlighting its potential for next-generation neuromorphic computing. This work expands the functional and scaling capabilities of vdW ferroelectric technology, highlighting its potential for next-generation artificial intelligence electronics.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"105 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145351633","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}

However, producing red-emitting InGaN micro-LEDs is challenging due to lattice mismatch with traditional GaN substrates. This mismatch causes strain relaxation, compositional gradients, and defects in high-indium-content InGaN films. These issues severely limit device efficiency, and the potential of alternative substrates to address these challenges is not fully explored. Here, we show that Al1-xScxN pseudosubstrates with adjustable lattice parameters greatly improve lattice matching of InGaN. Using plasma-assisted molecular beam epitaxy, we grow 120 nm-thick, phase-pure Al1-xScxN layers (0.1 < xSc < 0.2). This enables high-quality deposition of In0.28Ga0.72N layers and a uniform indium distribution compared to growth directly on GaN. AlScN-supported films exhibit no compositional pulling effect common for conventional substrates. This uniformity is confirmed by room-temperature photoluminescence, showing a narrow emission at 538 nm. Our results demonstrate that AlScN pseudosubstrates are promising for future integrated red micro-LED devices.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"1 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145351666","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}

In this paper, strategic anion substitution in cobalt LDH is an appealing strategy to produce a material with two-fold functionality, electrochemical and magnetocaloric response, offering a sustainable alternative to existing electrocatalysts and cryogenic refrigerants. It is unambiguously demonstrated that (poly)oxomolybdate-based specimens interleave in Co LDH nanosheets up to a Co:Mo = 1:0.4 ratio, leading to an interstratified material. This intercalation greatly benefits the kinetics of the oxygen evolution reaction for H2 production, boosting the catalytic sites due to the expansion of the interlayer space, induced by the bulky molybdates which also partially modify the Co oxidation state of αCo(OH)2 nanolayers, favoring charge transfer. In parallel, the interleaved Mo species strengthen superexchange interactions compared with pristine α-Co(OH)2, effectively adjusting the operating temperature toward the liquid hydrogen range (2030 K). This specific temperature range allows to fill a critical gap in magnetocaloric materials, as few systems can simultaneously achieve both large magnetic entropy changes and structural stability.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"47 1","pages":"e12458"},"PeriodicalIF":29.4,"publicationDate":"2025-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145351764","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cognitive impairment is a common and debilitating complication of traumatic brain injury (TBI), yet its underlying mechanisms remain poorly understood and effective clinical interventions are lacking. In this study, we observed persistent cognitive deficits in a mouse model of TBI, a phenomenon that has been widely documented in previous studies, and importantly, we found that these impairments were closely associated with increased hippocampal NSCs (H-NSCs) senescence. To investigate the cause of NSCs' senescence, we analyzed cerebrospinal fluid samples from TBI patients and hippocampal tissues from TBI mice and identified persistently elevated levels of IL-1β post TBI. In vitro, IL-1β successfully induced NSCs' senescence and suppressed neurogenesis. Induced pluripotent stem cell-derived small extracellular vesicles (iPSC-sEVs) reversed IL-1β-induced senescence and restored neurogenic potential in H-NSCs. In vivo, iPSC-sEVs alleviated cognitive deficits and H-NSC senescence after TBI. Integrated proteomic and NSC cell transcriptomic analyses revealed that the β-catenin/ID2/CDKN2B (p15INK4b) signaling axis plays a critical role in regulating H-NSC senescence, which was further validated through inhibitor experiments. In summary, our findings demonstrate that iPSC-sEVs attenuate NSC senescence and improve cognitive function following TBI via modulation of the β-catenin/ID2/CDKN2B (p15INK4b) axis.","PeriodicalId":21,"journal":{"name":"ACS Nano","volume":"58 1","pages":""},"PeriodicalIF":17.1,"publicationDate":"2025-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145339011","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Anticancer peptides were released through the hydrolysis of acid-labile amide bonds to induce cell apoptosis, while thio-perylene diimide radical anions with up to 67% NIR photothermal conversion efficiency could be generated through a hypoxia-induced biological reduction process. Thus, this approach enables the development of a dual-response nanomedicine to achieve combinational NIR photothermal therapy and chemotherapy. In the A549 lung cancer cell-derived xenograft model established in BALB/c nude mice, the tumor inhibition rate reached 68.0%.

These \"armed\" macrophages are then transferred into the infected host to capture bacteria and transport them to the surface of the skin through blood circulation, where sunlight can penetrate. Upon capturing bacteria, the photodynamic effect of Lyso710A is turned on by the macrophage's endogenous hypochlorous acid (HClO). When these macrophages reach the epidermis, the bacteria are eradicated by the photodynamic effect of the activated photosensitizer during exposure to sunlight.

Sodium-ion batteries (SIBs), using abundant sodium, offer an alternative to costly lithium-ion batteries (LIBs) but face challenges with lower energy density, slow ion transport, and limited cycle stability. This review critically examines metal-organic frameworks (MOFs) as next-generation electrolytes capable of addressing these challenges by following these mechanisms. High porosity and ordered channels (6-12 Å) facilitate uniform Na+ diffusion and reduce activation barriers from 1.23 to 0.36 eV, directly improving power density. Tunable functional groups with strategic electronegativity enable selective ion transport and dendrite suppression, thereby enhancing cycle stability. Framework versatility allows integration with polymers and ionic liquids, yielding ionic conductivities above 10-4 S cm-1 and boosting energy density. Charge transport occurs via both through-bond and through-space pathways, with the latter achieving up to 43-fold improvements in diffusion coefficients. By consolidating these findings, the review establishes a systematic structure performance framework: pore geometry governs ionic conductivity, functional groups control ion selectivity, and framework flexibility dictates mechanical stability during cycling.
