Transfer of Energy and Momentum Between Magnetoactive Surface Microstructure and a Solid Object
Advanced Engineering Materials, EarlyView.We demonstrate that magnetoactive multilamellar arrays subjected to a rotating magnetic field can function as platforms for controlled transport of physical objects. Through systematic experimental investigation, we elucidate the underlying physical mechanisms determining the upper limit of the achievable transportation speed in such magnetic “conveyor‐

Evaluation of alloys and coatings for use in automobile thermal reactors [PDF]
Several candidate alloys and coatings were evaluated for use in automobile thermal reactors. Full-size reactors of the candidate materials were evaluated in cyclic engine dynamometer tests with a peak temperature of 1040 C (1900 F).

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 ...

Corrosion stability of welded alloy for metal- ceramic system
, 2012 Objectives: The aim of this study was to test the elution of Co, Cr and Ni ions from laser and TIG welded Co-Cr alloys. Methods: Four commercial Co- Cr dental alloys were cast. The specimens were divided into 3 groups. The first group of samples was laser welded, second joint with TIG procedure and third used as a control group.
