Isotopically pure diamond 98.9% C and 1.1% C. This is useful for heat sinks for the semiconductor industry. Isotopically pure C diamond layers 20 micrometers thick are used as stress sensors due to the advantageous Raman spectroscopy properties of C. Isotopically pure diamond An isotopical pure diamond is a type of diamond that is composed entirely of one isotope of carbon. Isotopically pure diamonds have been manufactured from either the more common carbon isotope with mass number 12 (abbreviated as C) or the less common C isotope. Compared to natural diamonds that are composed of a mixture of C and C isotopes, isotopically
ACS Award in Pure Chemistry award was first awarded in 1931, with Linus Pauling the inaugural recipient. It is sponsored by the Alpha Chi Sigma Fraternity and the Alpha Chi Sigma Educational Foundation. Source: American Chemical Society List of prizes, medals and awards ACS Award in Pure Chemistry The American Chemical Society Award in Pure Chemistry is awarded annually by the American Chemical Society (ACS) "to recognize and encourage fundamental research in pure chemistry carried out in North America by young men and women." "Young" means born within 35 years of the awarding of the Award, which takes place at the Spring meeting of the
