To date, there are no effective clinical drugs available to improve long-term outcomes for post-stroke patients. A novel nucleic acid agent circSCMH1 which can promote sensorimotor function recovery in rodent and nonhuman primate animal stroke models has been found. However, there are still delivery challenges to overcome for its clinical implementation. Besides, its effects on post-stroke cognitive functions remain unexplored. Herein, lipid nanoparticle circSCMH1@LNP1 is established to deliver circSCMH1 and explore its therapeutic efficacy comprehensively. Distribution experiments demonstrate that intranasal administration of circSCMH1@LNP1 significantly increases circSCMH1 distribution in the peri-infarct region and reduces its non-specific accumulation in other organs compared to intravenous injection. Therapeutic results indicate that circSCMH1@LNP1 promotes synaptic plasticity, vascular repair, neuroinflammation relief, and myelin sheath formation, thereby achieving enhanced sensorimotor and cognitive function recovery in post-stroke mice. In conclusion, this research presents a simple and effective LNP system for efficient delivery of circSCMH1 via intranasal administration to repair post-stroke brain injury. It is envisioned that this study may bridge a crucial gap between basic research and translational application, paving the way for clinical implementation of novel circSCMH1 in post-stroke patient management.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"30 1","pages":""},"PeriodicalIF":29.4,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143713526","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}

Herein, instead of eliminating the Li plating, a Li plating regulation strategy that transforms dead Li plating into reversible active Li plating is proposed by using a lithium dendrite inhibitor to realize safe and long-lifespan LIBs. Remarkably, only 1 wt.% single-atom manganese (SAMn) in the Gr anode (Gr-SAMn) is sufficient to achieve a significant improvement, thus both the volumetric and mass-energy density remain roughly unaffected. The amount of dead Li on the Gr anode can be reduced by 90%, thereby enabling much-improved pouch cell performance at high rates and low temperatures. The capacity retention of the Gr-SAMn||NCM811 pouch cell is 86.2% (23.0% higher than that of the pristine Gr||NCM811 pouch) for 1500 cycles at 2 C, and the cell can even be cycled at 5C charge. Even cycling at −20 °C, the average coulombic efficiency (CE) can be improved from 97.95% to 99.94% by using SAMn additive. Hence, this promising strategy provides a novel alternative to solve the Li plating issue.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"23 1","pages":""},"PeriodicalIF":29.4,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143723864","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}

In this study, the novel 2D layered noble-metal dichalcogenide, PtSe2, is explored for efficient ethanol oxidation electrocatalysis from a microscopic perspective based on an on-chip microelectrochemical platform. While pristine PtSe2 demonstrates similar EOR activities to Pt, argon plasma treatment significantly enhances the performance on EOR activity, If/Ib ratio, onset and peak potentials, and durability. Detail investigations reveal that plasma treatment results in the exposure of PtSe2 surface, which is responsible for significantly enhanced EOR activity and poison-resistance as also confirmed by theoretical calculations. In situ electrical transport measurements for monitoring the catalyst surface intermediates, elucidate that both optimized OHads coverage and appropriate ethanol molecular adsorption on PtSe2 are the key for the high performance.

However, it is quite challenging to realize practical Li─S batteries under limited electrolytes and high sulfur loading, which may exacerbate problems of interface deterioration and low sulfur utilization. Herein, the coordination and mediation chemistry of arylboronic acids that enable energy-dense and long-term-cycling Li─S batteries is proposed. The coordination chemistry between NO3− and arylboronic acids breaks the resonance configuration of NO3− and thermodynamically promotes its reduction on the anode, contributing to a mechanically robust interface. The mediation chemistry between lithium arylborate and polysulfides distorts S─S/Li─S bonds, alters the rate-determining step from Li2S4→Li2S2 to Li2S6→Li2S4, and homogeneously accelerates the sulfur redox kinetics. Li─S batteries using 3,5-bis(trifluoromethyl)phenylboronic acid (BPBA) show excellent cycling stability (1000 cycles with a low capacity decay rate of 0.033% per cycle) and a high energy density of 422 Wh kg−1 under aggressive chemical environments (high sulfur loading of 17.4 mg cm−2 and lean electrolyte operation of 3.6 mL gS−1). The basic mechanism of coordination and mediation chemistry can be extended to other arylboronic acids with different configurations and compositions, thus broadening the application prospect of arylboronic acids in the electrolyte engineering of Li─S batteries.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"72 1","pages":""},"PeriodicalIF":29.4,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143713520","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}

In particular, the electronic density of state effective mass exhibits a nearly threefold increase, while ferromagnetism emerges from infancy when tuning the vacancy order from LRO to SRO.

However, phosphoric acid (PA) leaching remains a critical issue, diminishing energy density and durability, posing significant obstacle to the commercial development of HT-PEMFCs. To address this, composite membranes incorporating the carboxylic acid-modified polymer of intrinsic microporosity (cPIM-1) are designed as framework polymer, blended with polyvinylpyrrolidone (PVP) for HT-PEMFCs. The Lewis acid-base interactions between cPIM-1 and PVP created an extensive hydrogen-bonding network, improving membrane compatibility. The optimized microporous structure and multiple anchoring sites gave rise to “domain-limited” PA clusters, enhancing the capillary effect. Simultaneously, improved hydrophobicity synergistically optimizes catalytic interface, promoting continuous and stable proton transfer. The HT-PEMFCs based on PVP/cPIM-1 composite membrane achieved a peak power density of 1090.0 mW cm−2 at 160 °C, representing a 152% improvement compared to PVP/PES membrane. Additionally, it demonstrated excellent durability, with a voltage decay of 0.058 mV h−1 over 210 h of accelerated stress test corresponds to more than 5000 h of constant current density durability test.

However, excessive losses in polymer dielectrics caused by high carrier densities at high temperatures and strong electric fields often result in low energy storage efficiency, which is the most challenging problem that urgently needs to be solved. In existing studies, the losses are mainly suppressed by limiting carrier formation; however, it is very challenging to completely limit carrier formation, especially at high temperatures and strong electric fields. Therefore, this perspective proposes to regulate the carrier transport behavior through “guiding/constraining/blocking” forms rather than the previously oversimplified carrier limitation strategy, which further clarifies dominant structure factors that inhibit carrier transport to reduce losses and enhance energy storage efficiency. Meanwhile, the influence of different structural designs on carrier transport behavior, individually or collaboratively, must be systematically studied to determine the specific mode of carrier transport behavior, thereby establishing a relationship between carrier transport behavior and energy storage efficiency. The presented perspective is expected to offer a novel and effective theoretical basis for the design and fabrication of advanced polymer dielectrics with high capacitive energy storage levels in harsh environments.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"30 1","pages":""},"PeriodicalIF":29.4,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143723858","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}

Here, a single-layer lignin-based ultrathin separator (as thin as 15 µm) with exceptional intrinsic thermal stability and cycling performance is demonstrated. The separator is fabricated using lignosulfonate, a natural polymer derived as a byproduct of chemical pulping and biorefinery processes.

Inspired by the human brain, nonvolatile and volatile memory electronic devices have been employed to realize artificial neural networks and spiking neural networks, respectively, which have emerged as essential tools in machine learning. Molecular switches, capable of responding to electrical, optical, electrochemical, and magnetic stimuli, display a disruptive potential for emulating information storage in memory devices. This Review highlights recent developments on responsive molecules, their interfacing with low-dimensional nanostructures and nanomaterials, and their integration into electronic devices.
