Single‐Atom Photocatalyst as Floatable Artificial Leaf for Upcycling Oceanic Plastic Waste

open access: yesAdvanced Materials, EarlyView.
To resolve the catastrophic disaster of oceanic plastic pollution, the novel Ru single atom loaded ZnIn2S4 photocatalysts, in the forms of powder or floatable artificial leaf, were prepared for direct conversion of raw polypropylene plastic into valuable chemicals. The optimized catalyst exhibits exceptional performance, with a total formic/acetic acid

Immune and Stem Cell‐Mediated Bactericidal Amplification and Bone Remodeling for Infection Clearance and Osteointegration

open access: yesAdvanced Materials, EarlyView.
A pH‐responsive biomaterial interface integrates bactericidal peptides, cell‐recruiting peptides, and magnesium ions into a multifunctional system. Infection‐induced acidification triggers antimicrobial peptide release while cell‐recruiting peptides mobilize bone marrow stem cells.

Chronic Hypoxia Disrupts Spermatogenesis Through ASXL2–EZH2–Mediated Microtubule Destabilization

open access: yesAdvanced Science, EarlyView.
This study reveals the mechanism by which chronic hypoxia impairs spermatogenesis via the ASXL2–EZH2 axis, hindering the transition of spermatids from round to elongated forms. Key findings reveal that under hypoxic conditions, downregulated ASXL2 expression reduces EZH2 binding to the CEP162 promoter, leading to decreased H3K27me3 modification and ...
