Advanced Engineering Materials, EarlyView.Bimetallic (NiFe) and trimetallic (NiFeCr) nanoalloys (NAs) are synthesized using corresponding oxide mixtures using microwave hydrogen plasma within a few milliseconds. The process simultaneously 1) reduces metal oxides to metals; 2) downsizes the particles from micrometers to nanometers; and 3) blends the metals to form NAs.

Inflammatory Response‐Inspired Thermochromic Shield for Pneumatic Structures
Advanced Engineering Materials, EarlyView.A thermochromic shield for pneumatic structures is developed, using anhydrous sodium acetate powder and thermochromic pigment‐included solution. In this shield composed of three layers, the exothermic and thermochromic reactions, followed by the mixture of both components, occur promptly with an incident of penetrating damage as a sign of initial ...
