(especially of fissionable material) able to sustain a chain reaction in such a manner that the rate of reaction increases
Source: WordNetAs more of the semiconductor solute is added from the supercritical phase (due to a concentration gradient), a solid crystallite precipitates, and a nanowire grows uniaxially from the nanocrystal seed. Source: Internet
A supercritical fluid has the physical properties of a gas, but its high density confers solvent properties in some cases, which leads to useful applications. Source: Internet
Grey-blue represents supercritical liquid water.) Entropy is the above-mentioned unexpected and, to some, obscure integral that arises directly from the Carnot cycle. Source: Internet
Below a depth of about 1000 m, carbon dioxide is injected as a supercritical fluid, a material with the density of a liquid, but the viscosity and diffusivity of a gas. Source: Internet
By using metal nanocrystals as seeds, citation Si and Ge organometallic precursors are fed into a reactor filled with a supercritical organic solvent, such as toluene. Source: Internet
During part of this process, the assembly is supercritical, but not yet in an optimal state for a chain reaction. Source: Internet
