A refined MASH–HCC model identifies macrophage Gadd45b as a key orchestrator of inflammation-driven neoplastic progression

Abstract Metabolic dysfunction-associated steatohepatitis (MASH) is emerging as a leading driver of hepatocellular carcinoma (HCC), yet the molecular mechanisms linking metabolic stress, chronic inflammation and tumorigenesis remain poorly understood. Here we established a metabo...

Vacuum-based long-term thermal stability evaluation of metal-organic precursors for atomic layer deposition

Understanding the long-term thermal stability of metal-organic precursors is critical for maintaining consistent and reliable atomic layer deposition (ALD) performance. Conventional evaluations, such as thermogravimetric analysis (TGA) and bulk long-term thermal stability tests i...

Multifunctional Matrix‐Activated Electrodes Enabling Efficient Proton Transport and Durable Low‐Pt Operation for High‐Temperature Proton Exchange Membrane Fuel Cells

ABSTRACT Phosphoric acid (PA)‐related challenges, including PA loss, redistribution, and flooding, critically limit the performance and long‐term durability of high‐temperature proton exchange membrane fuel cells (HT‐PEMFCs) based on PA‐doped membrane electrode assemblies. Althou...

Influence of base metal geometry on heat dissipation, molten pool dynamics, and solidification behavior in GMAW bead formation

The geometrical configuration of the base metal can alter heat dissipation and molten pool behavior during gas metal arc welding (GMAW), even when the same nominal welding parameters are applied. This study investigated the effect of base metal width on heat dissipation, bead mor...

Sprayable MXene Hydrogels With Composition‐Driven Interfacial Stabilization and on‐Skin Gelation for Conformal Postsurgical Photothermal Therapy

ABSTRACT Oxidative degradation of Ti 3 C 2 T x MXene in aqueous and biological environments remains a persistent obstacle to its long‐term use in biomedical applications, yet the role of the surrounding polymer matrix in governing this process has received little systematic atten...
