Energy-assisted magnetic recording (EAMR) uses a laser-optical system integrated into the magnetic head to heat locally a fine-grained material of high magnetic anisotropy energy density above its Curie temperature, and store single bits in very small areas without being limited by the superparamagnetic effect. However, localized laser heating may affect the thermal stability of the carbon overcoat...
Large area synthesis of graphene has been realized on top of a nickel-coated micro platform using the Micro Chemical Vapor Deposition (Micro-CVD) system. The capability of ultra-fast heating and cooling provided by the MEMS platform is crucial for the controlled growth of graphene. Theoretical analysis shows that cooling rate is about 4 orders of magnitude higher than the conventional CVD system....
In this work, a simple, efficient and cost-effective in situ purification method has been developed based on gas-phase oxidation, in an effort to increase purity of single-walled carbon nanotubes (SWNT) in the course of SWNT synthesis by induction thermal plasmas. This newly developed purification method has the following advantages compared with the conventional off-line gas-phase oxidation techniques;...
