Surface‐Functionalized MXene for Enhanced Photocatalytic CO2 Reduction

Advanced Energy Materials, EarlyView.
Poly(catechol/p‐cresol)‐functionalized MXene (f‐MXene) enhances oxidation stability while preserving conductivity, enabling efficient interfacial electron transfer in a Cu/f‐MXene/reduced TiO2 photocatalyst. Strong Cu–f‐MXene synergy promotes CO2 activation and selective CH4 production, achieving a CH4 yield of 18.1 µmol g−1 (>200 × vs.

Water‐Mediated Proton Facilitation for Stable Acidic CO2 Electrocatalysis

Advanced Energy Materials, EarlyView.
Proton‐mitigating Cu─O─Ce sites accelerate *CO formation and PCET‐mediated *CO─*CHO coupling, enabling efficient multicarbon production at relatively low current density. Maintaining a retentive acidic pH suppresses parasitic hydrogen evolution and preserves in situ CO2 availability for carbon‐efficient acidic CO2 reduction.

Sonocatalytic carbon dioxide reduction for syngas production over surface‐roughened CuxO catalyst

AIChE Journal, EarlyView.
Abstract The transition to a carbon‐circular economy requires efficient technologies for converting CO2 into value‐added chemical feedstocks. Sonocatalytic CO2 conversion has recently emerged as a compelling approach to drive this conversion. Here, we report a surface‐roughened CuxO catalyst for sonocatalytic CO2 reduction in aqueous media, achieving a

The liver‐brain axis: A multidimensional regulatory network implicated in Alzheimer's disease pathogenesis and clinical implications

Animal Models and Experimental Medicine, EarlyView.
Schematic diagram of the core pathways of the liver‐brain axis in regulating AD. The liver regulates cerebral Aβ deposition, tau phosphorylation, and neuroinflammation through pathways such as metabolic detoxification (urea cycle, ketone body metabolism, glutathione antioxidant system), molecular secretion (APOE, CRP, FGF21, IGF‐1), and Aβ clearance ...
