High performance nitrogen-doped carbon for supercapacitor obtained by carbonizing eco-friendly and cheap polyaspartic acid

“…[1]. It has reported that nitrogen doping seems to be the most promising method for enhancing capacity, surface wettability and electronic conductivity of the carbon materials [2].…”

Facile and controllable synthesis of carbon-encapsulating carbonate apatite nanowires from biomass containing calcium compounds such as CaC2O4 and CaCO3

“…14,15 Furthermore, biomass could be used for fabrication of 1D carbonaceous nanomaterials such as carbon nanoanemones, carbon nanohorn-carbon nanotube hybrids, and cone-shaped graphitic whiskers. [16][17][18] Therefore, the search for unique carbon-apatite hybrid nanostructures from such promising renewable sources is a very fascinating and signicant challenge that can provide new opportunities for fundamental research and technological development in materials science and nanobiotechnology.…”

Functionalization of carbon nanohorns and their catalysis applications

“…Among various carbon nanostructures, carbon nanohorn (CNH) is one of the most interesting carbon nanostructures because of its unique morphology. The CNHs is carbon nanostructure with a cone-shaped single-layered graphitic aggregate with approximately 40-50 nm in length and approximately 2 and 3 nm in diameter [5,6]. It should be noted that the structure of a single cone-shaped single-layered graphitic aggregate is derived from a single-walled carbon nanotube (SWCNT) and ended by a five-pentagon conical cap.…”

“…It should be noted that the structure of a single cone-shaped single-layered graphitic aggregate is derived from a single-walled carbon nanotube (SWCNT) and ended by a five-pentagon conical cap. Based on the assembly or aggregating form, CNHs can be classified as Dahlia-like, bud-like, and seed-like structures with diameters of approximately 80-100 nm [2,4,6]. Interestingly, CNHs possess very high specific surface area and pore volume [2,4].…”

“…They are classified based on the assembly of the individual[4]. CNHs can be aggregated together to form Dahlia-like, bud-like, and seed-like structures with diameters of approximately 80-100 nm[2,4,6]. From structure as describe above, CNHs have a very high surface area, pore volume, chemical resistance, thermal stability, and hydrophobic surface property[2,4,15].…”
