Regeneration of Modified Bentonite Loaded with Phenol Using Supercritical Fluids

open access: yesAdsorption Science & Technology, 2004
The desorption of phenol from organically modified bentonite (ODTMA–bentonite) using supercritical fluids was studied. Parameters such as pressure, temperature, supercritical fluid flow rate and co-solvent (entrainer) concentration were investigated. The

Fluidity and supercriticality of the QCD matter created in relativistic heavy ion collisions [PDF]

open access: yes, 2010
In this paper we discuss the fluidity of the hot and dense QCD matter created in ultrarelativistic heavy ion collisions in comparison with various other fluids, and in particular suggest its possible supercriticality.

Electrochemistry in supercritical fluids [PDF]

open access: yesPhilosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2015
A wide range of supercritical fluids (SCFs) have been studied as solvents for electrochemistry with carbon dioxide and hydrofluorocarbons (HFCs) being the most extensively studied. Recent advances have shown that it is possible to get well-resolved voltammetry in SCFs by suitable choice of the conditions and the electrolyte.

Transonic flow theory of airfoils and wings [PDF]

open access: yes, 1976
There are plans to use the supercritical wing on the next generation of commercial aircraft so as to economize on fuel consumption by reducing drag. Computer codes have served well in meeting the consequent demand for new wing sections.

Evidence for structural crossover in the supercritical state

open access: yes, 2013
The state of matter above the critical point is terra incognita, and is loosely discussed as a physically homogeneous flowing state where no differences can be made between a liquid and a gas and where properties undergo no marked or distinct changes ...

Supercritical CO2-Pulse Cleaning in Deep Microholes

open access: yesJournal of Advanced Mechanical Design, Systems, and Manufacturing, 2008
A novel supercritical cleaning process was proposed for removing contamination in high aspect ratio trenches and microholes of highly integrated semiconductor devices. The supercritical CO2-pulse cleaning with the periodic pressure swing of supercritical
