Abstract This work demonstrates the processing, modeling, and characterization of nanocrystalline refractory metal tantalum (Ta) as a new structural material for microelectromechanical system (MEMS) thermal actuators (TAs). Nanocrystalline Ta films h

Polymers compared to structural materials usually have low strength and thermal conductivity. Here the authors show a fabrication method to form bio-compatible crystalline polyethylene nanofibers that exhibit ultra-high strength, thermal conductivity

Because they can achieve a high degree of molecular chain alignment in comparison with their bulk counterparts, the mechanical and thermal properties of polymer nanofibers are of great interest. However, due to their nanometer-scale size, it is diffi

Metal Amorphous Nanocomposite (MANC) materials offer low losses at high magnetic switching frequency, enabling high power density motors with increased rotational speed. While MANCs have high strength, they are brittle. The use of motor components su

Metal microelectromechanical systems (MEMS) provide attractive properties such as high reflectivity and high conductivity. They are typically processed using an organic sacrificial layer that is removed by an oxygen ash. This enables low-temperature

Hot switching and hydrocarbon-induced contact activation limit the lifetimes and exacerbate the surface erosion/damage in switches. However, the relative effects of voltage and contamination have not been studied. We report on these effects in Pt-coa
