Defect‐Engineered Multi‐Intermetallic Heterostructures as Multisite Electrocatalysts for Efficient Water Splitting

open access: yesAdvanced Science, EarlyView.
A self‐supporting nanoporous multicomponent CoCuMoNi catalyst is synthesized. Through the synergistic effect of multiphase interfaces, built‐in electric fields, and defect engineering, the binding energy of key reaction intermediates in hydrogen evolution reaction (HER)/oxygen evolution reaction (OER) is modulated, achieving high activity and stability

Unusual Thermal Transport in Few‐Layer Van der Waals Antiferromagnet CrOCl

open access: yesAdvanced Science, EarlyView.
Thermal transport serves as an ultra‐sensitive probe for detecting the magnetic order in 2D materials. Using the suspended thermal bridge method enhanced by Wheatstone bridges, it is, for the first time, observed anomalous critical behavior in few‐layer CrOCl near its Néel temperature.

Self‐Propelled In Situ Polymerized Nanoparticles Activating the STING Pathway for Enhanced Bladder Cancer Immunotherapy

open access: yesAdvanced Science, EarlyView.
A self‐propelled nanomedicine delivery system forms DMCU nanoparticles in the bladder via in situ polymerization of dopamine hydrochloride, Mn2+, cGAMP, and urease. The urease‐driven propulsion enhances retention and drug delivery. These nanoparticles activate the STING pathway, stimulating dendritic cells and T cells to boost anti‐bladder cancer ...

In Situ Construction of Multi‐Functional Polymer Network Toward Durable Perovskite Solar Cells

open access: yesAdvanced Science, EarlyView.
Acrylamide monomers were introduced into the perovskite precursor solution to 3D polymer networks at grain boundaries for stabilizing grain boundaries. By constructing weak chemical bond interactions with perovskite films, the polymer networks effectively reduce defect density and simultaneously suppress the degradation of perovskites.
