This paper focuses on the synthesis and mechanism of carbon nanospheres (CNS) coated with fewand multi-layered graphene (FLG, MLG). The graphitic carbon encapsulates the core/shell structure of the Ni/NiO nanoparticles via the chemical vapor deposition (CVD) method. The application of the resulting CNS and hybrids of CNS-FLG and CNS-MLG as reinforcement nanofillers in a polypropylene (PP) matri...

Catalytic substrate, which is devoid of expensive noble metals and enzymes for hydrogen peroxide (H₂O₂), reduction reactions can be obtained via nitrogen doping of graphite. Here, we report a facile fabrication method for obtaining such nitrogen doped graphitized carbon using polyacrylonitrile (PAN) mats and its use in H₂O₂ sensing. A high degree of graphitization was obtained with a mechanical...

Glassy carbon (GC) has been high-pressure high-temperature treated. An interesting morphology evolution from the pristine sample to the high pressure products was observed. It is found that GC can be graphitized under pressure at a temperature much lower than that at ambient condition. Furthermore the in−situ structure and electrical measurements of GC and graphitized glassy carbon (GGC) under ...

Wood-based carbon fiber derived from liquefied wood has the disadvantages of low mechanical strength and unstable performance. To improve its mechanical properties, wood-based carbon fiber precursors were impregnated with 5 wt.% and 8 wt.% boric acid solutions for 1 h and then carbonized at 900 °C for 1 h. The effect of boron content on fiber tensile strength and microstructure was investigated...

Multi-walled carbon nanotube (MWCNT)-based carbon/carbon composites were fabricated by the chemical vapor infiltration of pyrolytic carbon into pre-compressed MWCNT blocks. The pyrolytic carbon was deposited on the surface of the MWCNTs and filled the gaps between the MWCNTs, which improved the connection between the MWCNTs and formed a three-dimensional network structure. The mechanical and el...
