Microstructural and Mechanical Properties of a Hard Anodic Coating Applied on an Elastically Prestrained Aluminum Substrate

Advanced Engineering Materials, EarlyView.
Prestraining the substrate influences coating formation process. Higher prestraining force leads to higher coating thickness and lower hardness. Increase in prestraining force enhances preliminary damage in hard anodic coating. Fatigue damage mechanisms change for hard anodized prestrained samples.

Mesoporous Silica Microspheres by Super‐Fast Alkaline Etching of Micrometer‐Sized Stöber Particles

Advanced Engineering Materials, EarlyView.
Microscale silica particles are prepared along with a modified, scalable Stöber synthesis using the continuous addition of tetraethoxy silane to an ethanolic solution of ammonia with KCl. Etching with hydroxide ions at 95 °C gave porous analogs within minutes. Monodisperse particles are isolable in high yield after precipitation in ethanol.

Optimized Strategy for Fabricating High‐Aspect‐Ratio Periodic Structures Over Large Areas Using ps‐Direct Laser Interference Patterning

Advanced Engineering Materials, EarlyView.
Picosecond direct laser interference patterning (DLIP) enables precise microstructure fabrication on stainless steel. Using a multiscan approach, high‐aspect‐ratio patterns are achieved. Fluence influences structure growth and homogeneity, with smaller periods yielding better uniformity.

High‐Resolution Reverse Offset Printed Electroluminescent Multipixel Arrays for Scalable Future Wearable Displays

Advanced Engineering Materials, EarlyView.
This study explores the effects of pixel size and spacing when fabricating electroluminescent (EL) multipixel displays. COMSOL simulations identify the impact of pixel dimensions and spacing on electric field distribution and lighting efficiency. Flexible, high‐resolution EL pixel arrays are reverse offset printed, achieving a 96% reduction in pixel ...
