60 cage was mentioned in 1965 as a possible topological structure. [9] Eiji Osawa predicted the existence of C 60 in 1970. [10] [11] He noticed that the structure of a corannulene molecule was a subset of the shape of a football, and hypothesised that a full ball shape could also exist. Japanese scientific journals reported his idea, but ...
Buckminsterfullerene is a truncated icosahedron with 60 vertices, 32 faces (20 hexagons and 12 pentagons where no pentagons share a vertex), and 90 edges (60 edges between 5-membered & 6-membered rings and 30 edges are shared between 6-membered & 6-membered rings), with a carbon atom at the vertices of each polygon and a bond along each polygon ...
Fullerene or C 60 is soccer-ball-shaped or I h with 12 pentagons and 20 hexagons. According to Euler's theorem these 12 pentagons are required for closure of the carbon network consisting of n hexagons and C 60 is the first stable fullerene because it is the smallest possible to obey this rule.
Parts-per-million cube of relative abundance by mass of elements in an average adult human body down to 1 ppm. About 99% of the mass of the human body is made up of six elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus. Only about 0.85% is composed of another five elements: potassium, sulfur, sodium, chlorine, and magnesium ...
Buckminsterfullerene, a carbon molecule with the chemical formula C 60, also known as a buckyball; Caldwell 60, one of the Antennae Galaxies in the constellation Corvus; Corydoras osteocarus, a freshwater catfish; Carcinoma of the penis ICD-10 code; A kind of carbon called carbon fibre

Powdered Activated Carbon Treatment (PACT) is a wastewater technology in which powdered activated carbon [1] [2] is added to an anaerobic or aerobic treatment system. [3] The carbon in the biological treatment process adsorbs recalcitrant compounds that are not readily biodegradable, thereby reducing the chemical oxygen demand of the wastewater and removing toxins.

A review of works on fullerene toxicity by Lalwani et al. found little evidence that C 60 is toxic. [1] The toxicity of these carbon nanoparticles varies with dose, duration, type (e.g., C 60, C 70, M@C 60, M@C 82), functional groups used to water-solubilize these nanoparticles (e.g., OH, COOH), and method of administration (e.g., intravenous, intraperitoneal).
