Thermophysical and tribological measurements have been performed on carbon nanotube added silicon nitride composites. Higher thermal conductivity values were observed in the case of the sample with CNT than for the reference sample. As was observed from tribological measurements, nanocomposite Si3N4 without carbon nanotubes shows a higher friction coefficient than carbon nanotube - Si3N4. The results of wear study indicate that the Si3N4 ball (used as static partner) was more damaged with…

Semimetallic Graphene for Infrared Sensing.
TLDR
Using the semimetallic multilayer graphene, IR detection at room temperature is realized using high responsivity and detectivity, and the incident IR can be absorbed directly by the sensing material in the device.
