Micro-nano hybrid composites exhibiting desirable thermal conductivity levels due to the presence of specific ratios of graphite to graphene that have been found to reduce the overall thermal interface resistance. The composites are preferably epoxy matrix composites in some embodiments. Devices including ...
Graphene's electrical conductivity as a result of the delocalised π electrons is many orders of magnitude larger than silicon (1.56×102 S/m) which is commonly used in electronic devices. It's thermal conductivity is also outstanding making it suitable for applications in thermal management, such...
The calculations show that Umklapp-limited thermal conductivity of graphene grows with the increasing linear dimensions of graphene flakes and can exceed that of the basal planes of bulk graphite when the flake size is on the order of a few micrometers. The obtained results are in agreement with...

Although 3D graphene foam exhibited the least hydrophilicity, it could surprisingly achieve the highest H2O2 generation,0.6 mg cmcat−3 at −0.61 V (vs. Ag/AgCl), due to the contribution of higher surface area as well as superior electrical conductivity. However, compared with other carbon ...
Electrical Conductivity Good conductor due to delocalized electrons. Conductivity varies by allotrope; diamond is an insulator. 10 Thermal Properties High thermal resistance. Varies; diamond has high thermal conductivity. 13 Use Cases Lubricants, pencils, batteries. Diverse; including fuels, diamonds, biol...
The electrical conductivity of N-doped REGO depends on the synthesis and reduction methods. It has been reported that the electrical conductivity of N-doped graphene synthesized by the Hummer’s method and reduced under N2 is 56.8 Scm−1 [22], but when reduced under NH3 at 800 °C it ...
Graphite is used in pencils, lubricants,crucibles, foundry facings, polishes, brushes for electric motors, and cores of nuclear reactors. Its highthermaland electrical conductivity make it a key part of steelmaking, where it is used as electrodes inelectric arcfurnaces. In the early 21st century...
Additionally, DFT calculation confirmed that N, S double-doped graphene resulted in the redistribution of spin and charge density, leading to the enhancement of synergistic catalytic activity. Among double-doped graphene, the incorporation of metal elements enhances the electrical conductivity of doped ...
