Silica dispersions in nonpolar solvent
Hypothesis Silica nanoparticles can be dispersed in organic solvents (organosols) using surfactants, such as didodecyldimethylammonium bromide (DDAB). DDAB analogues prepared with lathanide tetrahalide counterions, either a high-magnetic moment ion (HoCl3Br, DDAH) or low-magnetic moment one (NdCl3Br, DDAN), are expected to produce charged particles but only DDAH-stabilized dispersions are expec...
متن کاملTransport of charged colloids in a nonpolar solvent
In nonpolar solvents, surfactants stabilize charge through the formation of reverse micelles; this enables the dissociation of charge from the surfaces of particles, thereby charge-stabilizing particle suspensions. We investigate the dynamics of such charged particles by directly visualizing their motion across a microfluidic channel in response to an external electric field. The presence of th...
متن کاملSolvent Modulation of Polysacharide Conformation
Polymers are widely used in solution to provide structure and function, e.g., viscoelasticity, colloidal stability, and delivery of actives. Underlying these functions are interand intra-molecular interactions that are modulated by the solvent used. Solvents can have a great impact on polymer conformation [Alexandridis and Yang, 2000]. A solvent may enable the dissolution of a certain polymer o...
متن کاملConformation of uncomplexed [Phe4, Val6] antamanide crystallized from nonpolar solvents.
[Phe4, Val6] antamanide, a synthetic, biologically active analog of the cyclic decapeptide antitoxin isolated from Amanita phalloides, has been crystallized from a mixture of n-hexane and methyl acetate, and its conformation has been established by the direct method of x-ray diffraction analysis, i.e., without the benefit of any heavy atom. The uncomplexed molecule contains a 2-fold rotation ax...
متن کاملNucleosome conformation: pH and organic solvent effects.
Monomer nucleosomes (nu 1) from chicken erythrocyte nuclei were examined in aqueous buffers (8 greater than pH greater than 3) and in solvent mixtures (i.e., water and ethanol, ethylene glycol, dioxane, dimethyl sulfoxide, 2-methyl-2,4-pentanediol, polyethylene glycol, sucrose, or urea). Circular dichroism, laser Raman spectroscopy of nu 1, and the fluorescence of nu 1 labeled with N-(3-pyrene)...
