Synthesis of carbon-encapsulated magnetic nanoparticles by pulsed laser irradiation of solution

Plasma-assisted synthesis of carbon encapsulated magnetic nanoparticles with controlled sizes correlated to smooth variation of magnetic properties

“…Compared to other encapsulation materials, carbon is lighter in weight, more stable in physiological environments/higher temperature, more biocompatible and can be easily functionalized to carry drugs over its surface [1]. Different methods have been used to synthesize these magnetic nanomaterials, such as chemical vapor deposition [7], combustion [8], magnetron and ion beam co-sputtering [9], laser irradiation [10], spray pyrolysis [11], pulsed plasma [12], thermal plasma assisted techniques including both transferred [13] and non-transferred arc based configurations [1]. It has been pointed out that many of these techniques usually produce particles with amorphous carbon layers only.…”

Transparent interconnections formed by rapid single-step fabrication of graphene patterns

“…Finally, the thin carbon layers are formed on the nickel foil by the rapid cooling process through fast thermal conduction after laser irradiation (step 6). The laser assisted vapor-liquidsolid process can be done between approximately several tens of picoseconds and several nanoseconds, 13,14 meaning that the process time is about a million times faster than that of the conventional CVD method.…”

Development of highly faceted reduced graphene oxide-coated copper oxide and copper nanoparticles on a copper foil surface

“…Actually, silica, polymers and graphitic materials hold promise to produce highly stable well-protected metal or metal oxide nanoparticles [11]. In particular, rGO-Cu core-shell nanostructures have been synthesized by CVD [12,13], hydrothermal synthesis [14] and pyrolysis of an organocopper compound [15,16,17].…”
