Intermediate-States Mediated 2D MoO Plasmon Enabling Pure-Phased CsPbX Photovoltaics with 27.33% Bifacial Efficiency.

All-inorganic CsPbX (X = I, Br, Cl) perovskites emerged as a crucial material for addressing the stability bottleneck due to their exceptional resistance to both light-thermal stress. However, their performance is limited by adverse optoelectronic dissipation arising from inadequate photon conversion and chaotic carrier energetics. Herein, the mechanism of the unique nonlinear plasmonic effect in van der Waals 2D MoO is elucidated, which is mediated by electronic intermediate states.

Ultrasound-activated piezoelectric hydrogel scaffold for synergistic immunomodulation and angiogenesis in accelerated wound healing.

Current wound therapies struggle to dynamically regulate immune responses and angiogenesis, often resulting in impaired healing, scarring, and poor tissue regeneration. The development of smart hydrogel scaffolds offers an opportunity to precisely modulate the wound healing process. Here, we present a pioneering wireless immunomodulatory strategy by integrating amino-modified barium titanate (BTN) nanoparticles with a natural collagen matrix, using oxidized gellan gum (OG) as a crosslinker, to fabricate a tilapia collagen (Col)-based biomimetic piezoelectric hydrogel scaffold (Col/OG/BTN).

Semi-tensor product based long-run behavior estimation of generalized asynchronous Boolean networks with time delays.

This paper investigates the long-run behavior estimation of generalized asynchronous Boolean networks with time delays, particularly the evolutionary trends of the attractor and its basin. First, the dynamic form of the original network is remapped into an equivalent augmented system based on the algebraic state-space representation, and a transition table is constructed. Second, definitions of delayed fixed points and delayed limit cycles are provided based on the augmented system.

Progress in the application of stem cell therapy for moyamoya disease.

Moyamoya disease (MMD) is a progressive cerebrovascular disorder that is characterized by stenosis or occlusion of the internal carotid artery and its branches, leading to ischemic or hemorrhagic stroke. Traditional surgical interventions, such as direct and indirect revascularization, have been the mainstays of treatment. However, the search for novel therapeutic approaches has spurred the exploration of stem cell (SC) therapy as a potential therapeutic option.

Glioma-Associated Mesenchymal Stromal/Stem Cells Derived Exosomal miR-191 Promotes the Proneural-to-Mesenchymal Transition in Glioblastoma Cells via PTEN/PI3K/AKT Signaling.

Background: The proneural-to-mesenchymal transition (PMT) represents a crucial phenotypic transformation in glioblastoma. Glioma-associated mesenchymal stromal/stem cells (GaMSCs) play a significant role in diverse biological processes of gliomas. However, the impact of exosomes released from GaMSCs (GaMSCs-Exos) on the PMT of glioblastoma remains inadequately understood.

Locking-chain electrolyte additive enabling moisture-tolerant electrolytes for sodium-ion batteries.

The unstable electrolyte-electrode interface and the trace HO in commercial organic electrolytes critically limit the cycling life of batteries. Herein, a locking-chain sodium 4,4'-(1,4-phenylenebis(oxy))-bis(butane-1-sulfonate)-15-crown-5 (15PBS) is designed for phase-to-interface electrolyte optimization. In the electrolyte phase, the strong hydrophilic sulfonate groups and 15-crown-5 in 15PBS effectively transform HO from a reactive aggregated state (strong H-bond) into an inactive state (weak H-bond) through adsorption, effectively suppressing HO-induced electrolyte decomposition.

Revealing unusual storage failure of single-crystal high-nickel cathodes during high-temperature and high-humidity exposure.

This work investigates an unusual storage failure in single-crystal high-nickel cathode materials under a simulated hot and humid environment. A transient passivation effect was observed during short-term exposure, followed by rapid performance deterioration and structural/chemical state transformations upon prolonged storage. The findings highlight the need for targeted ambient storage control and material modification strategies.

Remediation of groundwater contaminated with perfluoroalkyl acids and chlorinated ethenes using a microbial reductive dechlorination and sorptive material treatment train.

Groundwater contaminated by mixtures of perfluoroalkyl acids (PFAAs) and chlorinated ethenes (CEs) pose a significant remediation challenge due to the distinct characteristics of these two contaminant types. In situ adsorption barriers have been demonstrated as a promising remediation strategy for PFAA-contaminated groundwater plumes. However, most previous studies were carried out with only a single PFAA, and our understanding of the retention of comingled contaminant plumes, including multiple PFAAs and CEs in such barriers, remains limited.

The HCOOH yields 14.

Electrocatalytic Conversion of Glucose into Renewable Formic Acid Using "Electron-Withdrawing" MoO Support under Mild Conditions.

Electrocatalysis is a sustainable and effective approach to produce value-added chemical commodities from biomass, where highly effective catalyst is required. Since transition metal hydroxide is a feasible catalyst for electrochemical biomass conversion, rational optimization of its electrocatalytic activity is highly desired. Herein, electrocatalytic activity of glucose oxidation is significantly optimized by reducing the electron density at Ni active sites, which is achieved by depositing Ni(OH) at "electron-withdrawing" MoO support (Ni(OH)MoO).

Furthermore, we predicted JSW changes in the sixth year based on regression models.

Atomic mechanism of lithium dendrite penetration in solid electrolytes.

Lithium dendrite penetration through ceramic electrolytes is known to result in mechanical failure and short circuits, which has impeded the commercialization of all-solid-state lithium anode batteries. However, the underlying mechanism still remains under debate, due in part to a lack of in situ atomic-level observations of the dendrite penetration process. Here, we employ molecular dynamics simulations to reproduce the dynamic process of dendrite nucleation and penetration.

RNF146 Alleviates Myocardial Ischemia/Reperfusion Injury by Regulating the Ubiquitination-Mediated Degradation of DAPK1 to Inhibit Ferroptosis.

Ring finger protein 146 (RNF146) participates in regulating ferroptosis and ferroptosis is involved in myocardial ischemia/reperfusion injury (MI/RI). However, the effects and mechanisms of RNF146 in MI/RI are still unclear. TTC, H&E, IHC, DHE stainings, and echocardiography technology were used to determine the myocardial infarction area, pathological injury, level of RNF146, ROS, and cardiac function parameters, respectively.

The magnetoresistance (MR) of spin valves usually displays a symmetric dependence on the magnetic field. An antisymmetric MR phenomenon has been discovered recently that breaks field symmetry and has the potential to realize polymorphic memory. In this work, centimeter-size and high-quality CrTe/BiTe/CrTe van der Waals (vdWs) heterostructure devices have been prepared using molecular beam epitaxy (MBE).

Integration of Asymmetric Multi-Path Hollow Structure and Multiple Heterogeneous Interfaces in FeO@C@NiO Nanoprisms Enabling Ultra-Low and Broadband Absorption.

A reasonable construction of hollow structures to obtain high-performance absorbers is widely studied, but it is still a challenge to select suitable materials to improve the low-frequency attenuation performance. Here, the FeO@C@NiO nanoprisms with unique tip shapes, asymmetric multi-path hollow cavity, and core-shell heteroepitaxy structure are designed and synthesized based on anisotropy and intrinsic physical characteristics. Impressively, by changing the load of NiO, the composites achieve strong absorption, broadband, low-frequency absorption: the reflection loss of -55.
