Pickering‐Engineered Microparticles for Magnetically Guided Motion and Light‐Triggered Catalysis

open access: yesAdvanced Functional Materials, EarlyView.
Magnetically responsive wax microparticles stabilized by hematite cubes through the Pickering emulsification strategy are developed, showing controlled size, motion, and light‐activated catalytic activity. Annealing under a magnetic field enhances their mobility and steering.

Advancing Tandem Organic Solar Cells With Ternary Acceptor Control for High‐Power Modules and Solar‐to‐Ammonia Conversion

open access: yesAdvanced Functional Materials, EarlyView.
Tandem organic solar cells with optimized ternary acceptor engineering achieved a power conversion efficiency of 15.53% and enabled a high‐voltage mini‐module (Voc 6.11 V). Integration into a bias‐free PV‐EC system further demonstrated efficient solar‐to‐ammonia (STA) conversion (97% Faradaic Efficiency, 4± 2% STA efficiency), highlighting scalable ...

Vorticity‐Driven µ‐Platelet Rotation and Selective Packing for Vertical Thermal–Electrical Interconnects

open access: yesAdvanced Functional Materials, EarlyView.
We introduce a capillary‐filtering‐based particle‐filling (CFPF) process that simultaneously forms vertical thermal pathways and electrical vias within µ‐pores. In situ microfluidic analysis reveals that capillary‐driven velocity gradients generate vorticity that governs µ‐platelet rotation and vertical alignment.

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

open access: yesAdvanced 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 ...
