Laser Preset of MnOx Layer on High‐Entropy Alloy Surface for Ampere‐Level Ultra‐Stable OER Performance

Advanced Science, EarlyView.
3D printing enables a high entropy alloy‐derived, in situ formed MnOx overlayer that suppresses oxidation–reconstruction and mitigates anodic dissolution, while enhancing electrolyte wetting and bubble release to accelerate interfacial mass transport and OER kinetics.

Static and Dynamic Evaluation of Wind Potential in the Kara Region of Togo Using Artificial Neural Networks

TH Wildau Engineering and Natural Sciences Proceedings, 2021
Togo's energy situation is characterized by a low rate of access to electricity (38.07 % in 2017). In the Kara region, there is certainly a wind potential whose study is necessary for the production of electricity.

Real‐Time Ferroelectric Domain Wall Dynamics During Electric Poling and Depoling

Advanced Science, EarlyView.
Real‐time visualization of domain wall dynamics during alternating‐current poling, direct‐current poling, and electrical depoling in relaxor‐PT ferroelectric single crystals reveals distinct field‐dependent pathways and strong path dependence. Instant polarized light microscopy uncovers reversible domain wall nucleation, motion, and reconfiguration ...

Dual Impact of Long‐Lived Localized Carriers Induced by Restricted Hole Transfer in Organic Photovoltaics and Photocatalytic Hydrogen Evolution

Advanced Energy Materials, EarlyView.
This work clarifies why organic semiconductors perform differently in photovoltaic devices and photocatalytic nanoparticles. By examining D18:Y5 and PM6:Y6 systems, we show how aggregation, exciton lifetime, and interfacial charge transfer behavior govern energy‐conversion pathways.
