Advanced Functional Materials, EarlyView.A strategic spin‐polarization suppression in Fe single‐atom catalysts is proposed to enhance electrocatalytic reduction of NO to NH3. Employing a top‐down electrospinning strategy, self‐supported FeSAC with Fe‐N3S1 coordination structure and spin‐state transition is engineered from high‐spin to low‐spin.

Fluorine‐Free Soft Nanocomposites for High‐Speed Liquid Impact Repellence
Advanced Functional Materials, EarlyView.Fluorine‐free soft nanocomposite coatings are developed using silicone oil‐mediated mechanical‐stiffness control, enabling ‘dry’ liquid‐repellent surfaces that resist high‐speed water jet impacts up to ∼60 m/s. By tuning nanoparticle loading and oil content, the coatings also achieve >90% optical transparency, amphiphobicity with impact resistance to ...

Extreme solid state refrigeration using nanostructured Bi-Te alloys. [PDF]
, 2009 Materials are desperately needed for cryogenic solid state refrigeration. We have investigated nanostructured Bi-Te alloys for their potential use in Ettingshausen refrigeration to liquid nitrogen temperatures. These alloys form alternating layers of Bi{sub 2} and Bi{sub 2}Te{sub 3} blocks in equilibrium.
