Self‐Growing Conductive Hydrogels Establish Volumetric Biointerfaces for Cardiac Conduction Restoration

ABSTRACT Restoring three‐dimensional electrical conduction in infarcted myocardium remains a critical challenge, as conventional conductive hydrogel patches largely remain surface‐confined and prevent electrical coupling of residual cardiomyocytes within fibrotic scars. Here, we...

Exploring the hydrogen abstraction pathway in HOM formation from α -pinene photooxidation systems under varying NO conditions

Abstract. Highly oxygenated organic molecules (HOM) are formed via autoxidation during ⚫OH-initiated oxidation of α-pinene. We investigated the relative contributions of OH-addition and hydrogen (H)-abstraction to HOM formation from α-pinene photooxidation under varying nitrogen...

Engineered DynamicCo2+ Sites Resolve theComplete Reaction Network for C(sp3)–H Oxidation

Abstract The dynamic evolution of active sites under operating conditions fundamentally dictates catalytic performance, yet state-of-the-art studies remain confined to passive observation, i.e., they are unable to intervene in detrimental dynamics or translate beneficial ones int...

Noninvasive Detection of MASH and Fibrotic Burden Using Ultrasound‐Derived LIID and LSM in MASLD: A Multicenter Study

ABSTRACT Background and Aims Metabolic dysfunction‐associated steatohepatitis (MASH), the progressive form of metabolic dysfunction‐associated steatotic liver disease (MASLD), is associated with adverse hepatic and cardiometabolic outcomes. The study aimed to validate a novel qua...

Liquid Crystal Elastomer‐Based Haptic Pixel Arrays at Your Fingertips for Advanced Human–Machine Interfaces

Genetic Predisposition and Pharmacological Effects Shape the Divergent Effects of Type 2 Diabetes on Atherosclerosis

Abstract Type 2 diabetes mellitus (T2D) increases the risk of atherosclerotic diseases, including coronary artery disease (CAD), but decreases that for abdominal aortic aneurysm (AAA), forming an intriguing diabetes-atherosclerosis paradox. We investigate how genetic underpinning...

Enzymatic Ligation-Enhanced Catalytic Hairpin Assemblyfor Accelerated Kinetics with Restricted Leakage

Abstract Enthalpy-driven catalytic hairpin assembly (CHA) suffers from an inherent trade-off, wherein enhanced reaction kinetics is inevitably accompanied by elevated nonspecific background. Catalytic hairpin assembly-and-cyclization (CHAC) integrates CHA with enzymatic ligation,...

Fractional‐Order Modeling and Gain Curve Analysis of Full‐Bridge CLLC Resonant Converter
