This resulted nitrogen-doped graphene-copper composite possesses an electrical resistivity of 0.16 Ω·cm at room temperature, far lower than that of copper. In addition, the composite has superior thermal conductivity (538W/m·K at 25°C) which is 138% of copper. The combination of excellent...
Graphene is conventionally produced by the chemical reduction of GO; however, this product is prone to aggregation and still shows defects as the remaining functional groups cause disorder in the electronic structure of the graphene leading to reduced electrical conductivity [118]. Alternatively, the ...
and efficient sterilization method. In the presence of an external NIR light source, PTT materials convert light energy into heat energy to kill cells. The most commonly used PTT materials include metal nanoscale materials, such as gold, silver, palladium, copper NPs, graphene and carbon nanotubes...

Graphene has a good conductivity even at room temperature which exhibits excellent electrical properties due to the π-electrons which are free to move in the plane of graphene. In particular, motivated by its high theoretical surface area, high mechanical flexibility, ultrathinness, good electrical ...
