Isotopically pure diamond C or 100% C. The isotopes of carbon can be separated in the form of carbon dioxide gas by cascaded chemical exchange reactions with amine carbamate. Such CO can be converted to methane and from there to isotopically pure synthetic diamonds. Isotopically enriched diamonds have been synthesized by application of chemical vapor deposition followed by high pressure. The C isotopically pure, (or in practice 15-fold enrichment of isotopic number, 12 over 13 for carbon) diamond gives a 50% higher thermal conductivity than the already high value of 900-2000 W/(m·K) for a normal diamond, which contains the natural isotopic mixture of
What Time Is Love? "What Time Is Love?" was given international commercial releases on many occasions and in many forms between 1988 and 1992. The following lists detail most of these, but are not exhaustive. "What Time Is Love? (Pure Trance Original)" (catalogue number KLF 004T) was first released on 17 October 1988, and deleted following initially low UK media interest and sales. The reaction from continental Europe's clubbers and DJs led to further European releases in 1989 and 1990. In late 1989, a US edition of "Pure Trance 1" (sea-green writing on a black sleeve, and slightly different typography) was issued on the
