Sir Harold Walter Kroto FRS [2] [3] (born Harold Walter Krotoschiner; 7 October 1939 – 30 April 2016) was an English chemist.He shared the 1996 Nobel Prize in Chemistry with Robert Curl and Richard Smalley for their discovery of fullerenes.
The method was simple and efficient to prepare the material in gram amounts per day (1990) which has boosted the fullerene research and is even today applied for the commercial production of fullerenes. The discovery of practical routes to C 60 led to the exploration of a new field of chemistry involving the study of fullerenes.
Fullerenes had been predicted for some time, but only after their accidental synthesis in 1985 were they detected in nature [3] [4] and outer space. [5] [6] The discovery of fullerenes greatly expanded the number of known allotropes of carbon, which had previously been limited to graphite, diamond, and amorphous carbon such as soot and charcoal.
The 1996 Nobel prize in chemistry was given to Kroto, Curl, and Smalley for their discovery of the fullerene. [ 128 ] On July 12, 2004, the United States Post Office released a new commemorative stamp honoring R. Buckminster Fuller on the 50th anniversary of his patent for the geodesic dome and by the occasion of his 109th birthday.
These are carbon rich grains expelled by old stars such as R Corona Borealis. The result of this collaboration was the discovery of C 60 and the fullerenes as the third allotropic form of carbon. Subsequent discoveries included the endohedral fullerenes, and the larger family of fullerenes the following year. [28] [29]

The result of this collaboration was the discovery of C 60 (known as Buckyballs) and the fullerenes as the third allotropic form of carbon. [8] Smalley recognized that the structure of C 60 was like that of a soccer ball after cutting and tapping hexagons together in a three-dimensional manner, utilizing 20 hexagons and 12 pentagons. [9]
