Engineering Carbon Cloth‐Catalyst Interfaces for Pt‐Free Hydrogen Evolution Across the Full pH Spectrum

open access: yesAdvanced Science, EarlyView.
Interfacial synergy between carbon cloth and Pt‐free metal/nonmetal catalysts enhances charge transfer, wettability, active site accessibility, and hydrogen bubble release, enabling efficient and durable hydrogen evolution across acidic, neutral, and alkaline media for scalable green hydrogen production.

A Bio‐Inspired Visual Sensor With UV‐to‐NIR Fusion for Enhanced Recognition in Autonomous Driving Systems

open access: yesAdvanced Science, EarlyView.
Inspired by the sophisticated multilayer retinal architecture found in Pacific salmon eyes, a novel van der Waals heterojunction sensor based on NbNiTe5/BP is designed. Upon illumination at distinct wavelengths of 365 and 820 nm, the device exhibits distinctive bipolar photocurrent responses with opposite polarities. This unique optoelectronic behavior

ROS/pH‐Responsive Phenylboronic Acid–Chitosan Nanoparticles Improve Silymarin‐Mediated Hepatoprotection After Hepatectomy With Gut‐Liver Axis‐Associated Responses

open access: yesAdvanced Science, EarlyView.
Bioactive phenylboronic acid–chitosan nanoparticles enable responsive silymarin delivery for post‐hepatectomy liver protection. The nanoplatform integrates antioxidant and antibacterial functions, improves hepatic recovery, and is associated with coordinated shifts in gut microbiota, metabolites, cytokines, and hepatic proteomic pathways, suggesting a ...

Curvature‐Directed Elongation and Chiral Tilting Drive Asymmetric Tissue Patterning

open access: yesAdvanced Science, EarlyView.
Curvature and cell handedness together break tissue symmetry. On convex and concave surfaces, cells elongate along opposite geometric axes and tilt in a consistent chirality‐driven direction, yielding opposite alignment patterns from the same cells. Reversing intrinsic cell chirality reverses both.

Relation of Stump Length with Various Gait Parameters in Trans-tibial Amputee

open access: yesOnline Journal of Health & Allied Sciences, 2008
The purpose of this paper is evaluating the impact of stump length of unilateral below knee amputees (BKA) on different gait parameters. Nine unilateral BKA were chosen and divided into three groups comprising patients with short, medium, and long stump ...

Remote Ischemic Post‐Conditioning Preserves the Neurovascular Unit by Brain‐Derived Gas6 That Drives Monocyte‐Derived Macrophage Reprogramming via Axl and Vimentin after SAH

open access: yesAdvanced Science, EarlyView.
Subarachnoid hemorrhage (SAH) triggers monocyte‐derived macrophage (MDM) infiltration and M1‐like polarization via Vimentin upregulation, leading to neurovascular unit disruption and cognitive dysfunction. Remote ischemic postconditioning (RIPostC) upregulates neuronal Gas6, which activates Axl on MDMs to downregulate Vimentin and drive reparative M2 ...
