Journal ArticleDOI
Thermal conductivity of amorphous carbon thin films
TL;DR: In this paper, the authors measured the thermal conductivities of amorphous carbon thin films in the temperatures range 80-400 K using the 3ω method using the effective medium theory, which provides a phenomenological description of the variation of conductivity with mass density.
Journal ArticleDOI
Silicon nitride coating on titanium to enable titanium-ceramic bonding.
TL;DR: A 1-microm thick Si3N4 coating was applied to a titanium surface using a plasma-immersion implantation and deposition method and shown to enable significant improvement in Ti-ceramic bonding.
Journal ArticleDOI
Streaming metal plasma generation by vacuum arc plasma guns
TL;DR: In this paper, the authors have developed several different versions of repetitively pulsed vacuum arc metal plasma gun, including miniature versions, multicathode versions that can produce up to 18 different metal plasma species between which one can switch, and a compact high-duty cycle well-cooled version, as well as a larger dc gun.
Journal ArticleDOI
Bioactive surface coatings for nanoscale instruments: Effects on CNS neurons
TL;DR: The method and materials could have important ramifications in a number of areas of research and biotechnology, for example for chronic implantation of microelectrode arrays in the cerebral cortex for neuroprosthetic and neural monitoring application and for research on the human central nervous system.
Journal ArticleDOI

TL;DR: A new technique of picosecond time-resolved x-ray absorption spectroscopy is used to study the bonding of liquid carbon at densities near that of the solid, showing a change from predominantly sp-bonded atomic sites to a mixture of sp, sp2, and sp3 sites.
