Is It Real Type‐II or S‐Scheme? A Three‐Phase Diagnostic Protocol for Identifying Potentially Mislabeled Heterojunction Photocatalysts

Advanced Functional Materials, EarlyView.
Diagnostic analysis via the heterojunction validation funnel. The funnel illustrates the hierarchical stratification of 30 reported Type‐II systems based on the three‐phase, seven‐step diagnostic framework. Complete validation through all phases is achieved by only 3.3% of systems, while 96.7% lack full mechanistic validation, revealing a pervasive ...

Shape Memory Microneedle to Prevent Risks of Reproductive Hormone Therapy by Switching Sustained to Burst Release Under a Single Transdermal Insertion

Advanced Functional Materials, EarlyView.
A shape‐memory microneedle system enables reproductive hormone therapy through a single transdermal insertion. The X‐shaped device sustains follicle‐stimulating hormone release for three days, and mild heating restores the O shape to trigger burst human chorionic gonadotropin release.
