Dynamically Actuated Reconfigurable Topographical Surface Enables Active Control of Implant‐Associated Infections

Advanced Functional Materials, EarlyView.
A dynamically actuated reconfigurable topographical surface (DARTS) integrates contact‐mediated bactericidal nanotopography with programmable mechanical actuation to actively disrupt bacterial biofilms. Dynamic surface reconfiguration enhances bacterial killing and suppresses implant‐associated infections in vivo, providing a new strategy for active ...

Boosting Conversion Efficiency in Zn3P2/InP Solar Cells Via Nanoscale Junction Engineering

Advanced Functional Materials, EarlyView.
This study demonstrates the efficacy of selective area epitaxy (SAE) in enhancing the conversion efficiency of a Zn3P2${\rm Zn}_3{\rm P}_2$/InP heterojunction solar cell. The impact of the SAE pattern dimensions on the performance parameters is investigated. Small size opening limits Jsc because of current crowding whereas large size opening limits Voc

Coordination‐Modulated Catalytic Pathways at Carbon Dots‐Supported Single‐Atom Sites Revealed by Thiol Interactions

Advanced Functional Materials, EarlyView.
Carbon dots‐supported single‐atom catalysts provide a model platform for uncovering how coordination interactions regulate catalytic reactivity. Thiol binding at Ru‒N4 centers reshapes the reaction energy landscape of H2O2 activation, dynamically modulating ROS‐generation pathways through electronic‐structure perturbation.

Creep-sintering of zinc oxide

Journal of Materials Science, 1987
The simultaneous creep and densification of zinc oxide powder compacts was studied, using a loading dilatometer, at 725° C subjected to uniaxial stresses of up to 0.25 M Pa. Between relative densities of 0.50 and 0.85, the dependence of the uniaxial creep rate on density can be described in terms of a stress intensification factor,ϕ, of the formϕ ∼ exp

Tailoring Light Management in All‐Perovskite Tandem Solar Cells: The Impact of Nanotextures

Advanced Functional Materials, EarlyView.
To further improve the power conversion efficiency of all‐perovskite tandem solar cells, light management strategies need to be implemented. Front‐sided nanotextures reduce reflection losses, which boosts light absorption, thus increasing the tandem JSC, which is further supported by reducing parasitic absorption.
