  • PROCESS FOR PREPARING CARBON PROTECTED SUPERPARAMAGNETIC OR MAGNETIC NANOSPHERES
    Publication number: 20130302428
    Abstract: A process for the preparation of carbon protected superparamagnetic or magnetic nanospheres is claimed which comprises the steps: (A) coating FexOy particles with an organic polymer, (B) coating the product obtained in step (A) with silica, (C) subjecting the product of step (B) to pyrolysis conditions, and (D) removing silica. According to present process, structurally stable carbon protected magnetic nanospheres were obtained, which can be dispersed in various solvents like water, EtOH, toluene, etc.

  • Carbon materials with interconnected pores
    Patent number: 8563124
    Abstract: Methods of forming an electrically-conductive mesoporous carbon structure with interconnected pores or highly interconnected pores, and the resulting structures are described. The structure is formed by providing a mesoporous template, filling the mesopores with an organic precursor, polymerizing the organic precursor, pyrolyzing the polymerized organic precursor, and etching away the template.
