Solutions of C 60 can be oxygenated to the epoxide C 60 O. Ozonation of C 60 in 1,2-xylene at 257K gives an intermediate ozonide C 60 O 3, which can be decomposed into 2 forms of C 60 O. Decomposition of C 60 O 3 at 296 K gives the epoxide, but photolysis gives a product in which the O atom bridges a 5,6-edge.
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 ...
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).
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
The carbon atoms are in the same locations as the silicon and aluminum atoms of the mineral sodalite. The space group, I 4 3m, is the same as the fully expanded form of sodalite would have if sodalite had just silicon or just aluminum. [30] bct-carbon: Body-centered tetragonal carbon was proposed by theorists in 2010. [31] [32]
The average 70 kg (150 lb) adult human body contains approximately 7 × 10 27 atoms and contains at least detectable traces of 60 chemical elements. [5] About 29 of these elements are thought to play an active positive role in life and health in humans.

Calcium is also used to strengthen aluminium alloys used for bearings, for the control of graphitic carbon in cast iron, and to remove bismuth impurities from lead. [43] Calcium metal is found in some drain cleaners, where it functions to generate heat and calcium hydroxide that saponifies the fats and liquefies the proteins (for example, those ...
