Exploiting Device Deformability for Fluid and Particle Manipulation

Small, Volume 22, Issue 39, 13 July 2026.
Deformable devices enable fluid and particle manipulation modes that are inaccessible to rigid platforms. This review examines soft materials and architectures that translate controlled deformation into microscale fluid operations such as pumping, valving, mixing, and particle handling.

Oxide‐Free Titanium Coatings by Wire Arc Spraying in a Silane‐Doped Inert Atmosphere

Advanced Engineering Materials, Volume 28, Issue 12, 17 June 2026.
A silane‐doped argon atmosphere enables the production of oxide‐free titanium coatings via twin‐wire arc spraying at ambient pressure. This innovative approach eliminates residual oxygen, creating process conditions that prevent oxidation and nitride formation.
