The Influence of Graphite Orientation on the Current-Carrying Friction Performance of Copper–Graphite Composite Materials

open access: yesLubricants
In response to the need to optimize the performance of copper–graphite current-carrying friction materials, spark plasma sintering (SPS) technology was used to prepare copper–graphite composite materials with different graphite orientations.

Beyond double-resonant Raman scattering: UV Raman spectroscopy on graphene, graphite and carbon nanotubes

open access: yes, 2015
We present an analysis of deep-UV Raman measurements of graphite, graphene and carbon nanotubes. For excitation energies above the strong optical absorption peak at the $M$ point in the Brillouin zone ($\approx 4.7\,\text{eV}$), we partially suppress ...

Structural and Morphological Characterization of the Expanded Graphite Obtained by Ball Milling and HF Leaching

open access: yesIranian Journal of Materials Science and Engineering, 2021
In this research, expanded graphite (EG) was successfully fabricated using a simple ball milling process followed by hydrofluoric (HF, 10 wt. %) leaching. The effects of ball milling time (0-15 h) and leaching time (1-24 h) on the exfoliation of graphite
