Tuning the Morphology of Self‐Assembled Nanopatterns on MgO(001) Surfaces by Sequential Broad‐Beam Ion Irradiation

physica status solidi (RRL) – Rapid Research Letters, EarlyView.
A two‐step approach based on broad‐beam ion irradiation is demonstrated to produce fine‐tuned self‐assembled surface patterns on MgO(001). It shows an efficient route to modifying the crystalline MgO(001) surface topography in a controlled way, making use of its very specific behavior in terms of both the pattern morphology and patterning dynamics.

Next‐Generation Aerogel Electrocatalysts for Oxygen Reduction Reaction

Small, EarlyView.
ABSTRACT Aerogel‐based electrocatalysts have become a groundbreaking class of materials for the oxygen reduction reaction (ORR), distinguished by their ultralight nature, pore networks, and outstanding electrical conductivity. Their interconnected three‐dimensional frameworks offer abundant active sites, efficient diffusion channels, and continuous ...

Ultrahigh Stiffness and Energy Absorption Properties of Isotropic Metallic Closed Cell Microlattices

Small, EarlyView.
True closed cell microlattices without holes are fabricated for the first time using a novel Laser Sheet Fusion additive manufacturing technique. These microlattices exhibited isotropy in stiffness and surprisingly, strength and plasticity as well, despite orientation‐dependent failure mechanisms. Furthermore, material work hardening is shown to be key
