An aq. soln. of cationic, high mol. wt. poly(diallyldimethylammonium chloride) (I) [26062-79-3], synthesized in very alk. soln. with a ternary initiation system, is added in amts. of 0.25-4.0 mL/L to accelerate sedimentation of solid particles from coal-co ...
An overarching computational framework unifying several optical theories to describe the temporal evolution of gold nanoparticles (GNPs) during a seeded growth process is presented. To achieve this, we used the inexpensive and widely available optical exti ...
The microscopic description of the interface of colloidal particles in solution is essential to understand and predict the stability of these systems, as well as their chemical and electrochemical reactivity. However, this description often relies on the u ...
Sedimentation of solids is accelerated and complete, resulting in a high-quality effluent, when a 0.1% soln. of equal parts of poly(dimethyl-diallyl-ammonium chloride) cationic flocculant and a nonionic or anionic polyacrylamide is used at a rate of 0.25-4 ...
Selective IR vibrational predissocn. (IRVP) of van der Waals clusters in a free jet is an effective way to sep. isotopes. Abs. sepn. factors a in excess of 1.1 were obsd. upon irradn. of a beam of SF6 dild. in Ar with a 20 W CO2 laser. Selection of the wav ...
The exo- and endo-irontricarbonyl complexes of 5,6-dimethylidene-2-exo-norbornyl alcohols 10x, 10n, p-bromobenzenesulfonates 11x, 11n, acetate 12x and of the 2,3-dimethylidene-7-anti-norbornyl alcohols 17x, 17n, p-bromobenzenesulfonates 19x, 19n and acetat ...
