Despite the great importance of ionic processes, however, the intrinsic features of single ion have rarely been examined experimentally, because the dissolution process occurs in solution. Most previous experiments have measured only the averaged features of ions6,7,8. When sodium chloride (NaCl) ...
Uranium-bearing ores are lixiviated by allowing a dilute aqueous alkali metal, generally sodium, carbonate and/or bicarbonate, to seep uniformly through a mass of crushed ore without filling the interstices between the particles of ore, the volume of solution passing through the mass being between...

Polymer flooding is a proven chemical Enhanced Oil Recovery (cEOR) method that boosts oil production beyond waterflooding. Thorough theoretical and practical knowledge has been obtained for this technique through numerous experimental, simulation, and fi
Briefly, Au nanoparticles (NSp) were synthesized with a diameter of 30–40 nm as core by a standard sodium citrate reduction method. Then freshly prepared aqueous solution of 1 mM (3-aminopropyl) trimethoxysilane (APS, Sigma Aldrich) was added to the gold sol under vigorous magnetic ...
In vitro simulation of CHA-heme particles formation using synthetic CHA and hemin. A solution of CHA in dilute hydrochloric acid (pH < 2 as in the stomach) was mixed with aliquot of hemin and the resulting mixture was neutralized to pH ~ 6 (as in small intestine) by the additio...
A method for reducing the permeability in a desired area of a formation wherein a foamed gel is formed in-situ by injecting a solution into said formation. Said solution comprises a gellable compositi
The deprotonation is generally carried out by the addition of an aqueous solution of soda. The immonium salt of the general formula (IV) may be obtained by the action of phosphorus oxychloride followed by the possible addition of an alkali perchlorate such as sodium perchlorate on to a derivati...
