	Supercritical may refer to: Critical mass Critical Mass Critical Mass is a bicycling event typically held on the last Friday of every month in over 300 city around the world. While the ride was originally founded in 1992 with the idea of drawing attention to how unfriendly the city was to bicyclists, the leaderless structure of Critical Mass makes it impossible to assign it any one specific goal... , the smallest amount of fissile material needed for a sustained nuclear chain reaction Critical temperature Critical temperature The critical temperature, Tc, of a material is the temperature above which distinct liquid and gas phases of matter do not exist. As the critical temperature is approached, the properties of the gas and liquid phases become the same resulting in only one phase: the supercritical fluid.... , Tc, the temperature above which distinct liquid and gas phases do not exist Supercritical fluid Supercritical fluid A supercritical fluid is any substance at a temperature and pressure above its critical point . It can Diffusion through solids like a gas, and Solvation materials like a liquid.... , a substance at a temperature and pressure above its thermodynamic critical point Supercritical carbon dioxide Supercritical carbon dioxide Supercritical carbon dioxide refers to carbon dioxide that is in a fluid state while also being at or above both its critical temperature and pressure, yielding rather uncommon properties.... , same as above, applied to carbon dioxide Supercritical fluid chromatography Supercritical fluid chromatography Supercritical Fluid Chromatography is a form of normal phase chromatography that is used for the analysis and purification of low to moderate molecular weight, thermally labile molecules.... , high performance liquid chromatography (HPLC), using supercritical carbon dioxide as the mobile phase Supercritical airfoil Supercritical airfoil A supercritical airfoil is an airfoil designed, primarily, to delay the onset of wave drag in the transonic speed range. Supercritical airfoils are characterized by their flattened upper surface, highly cambered aft section, and greater leading edge radius as compared to traditional airfoil shapes.... , an airfoil designed to delay the onset of wave drag in the transonic speed range Supercritical drying Supercritical drying Supercritical drying is a process to remove liquid in a precisely controlled way, similar to freeze drying. It is useful in the production of Microelectromechanical systems , in the drying of spices, is commonly used in the production of aerogel and in the preparation of biological specimens for scanning electron microscope.... , the process to remove liquid in a precisely controlled way, similar to freeze drying Supercritical water reactor Supercritical water reactor The Supercritical water reactor is a Generation IV reactor concept that uses Supercritical fluid as the working fluid. SCWRs are basically LWRs operating at higher pressure and temperatures with a direct, once-through cycle.... (SCWR), a Generation IV nuclear reactor concept that uses supercritical water as the working fluid Supercritical water oxidation Supercritical water oxidation Supercritical water oxidation or SCWO is a process that occurs in water at temperatures and pressures above a mixture's thermodynamic critical point.... or SCWO, a process that occurs in water at temperatures and pressures above a mixture's thermodynamic critical point Supercritical flow Supercritical flow A supercritical flow is when the flow velocity is larger than the wave velocity. The analogous condition in gas dynamics is supersonic.Information travels at the wave velocity.... , when the flow velocity is larger than the wave velocity Supercritical steam generators Boiler A boiler is a closed Pressure vessel in which water or other fluid is heated. The heated or vaporized fluid exits the boiler for use in various processes or heating applications.... , a steam generator operating above the critical point of water, hence having no water - steam separation Hopf bifurcation Hopf bifurcation In bifurcation theory a Hopf or Andronov–Hopf bifurcation, named after Eberhard Hopf and Aleksandr Andronov, is a local bifurcation in which a fixed point of a dynamical system loses stability as a pair of complex conjugate eigenvalues of the linearization around the fixed point cross the imaginary axis of the complex plane.... , a local bifurcation ; when the first Lyapunov coefficient is negative, the bifurcation is called supercritical Pitchfork bifurcation Pitchfork bifurcation In bifurcation theory, a field within mathematics, a pitchfork bifurcation is a particular type of local bifurcation. Pitchfork bifurcations, like Hopf bifurcations have two types - supercritical or subcritical.... , similar to the case of a Hopf bifurcation
