We studied the dissolution dynamics of CO2 gas bubbles in a microfluidic channel, both experimentally and theoretically. In the experiments, spherical CO2 bubbles in a flow of a solution of sodium dodecyl sulfate (SDS) first shrink rapidly before attaining an equilibrium size. In the rapid dissolution regime, the time to obtain a new equilibrium is 30 ms regardless of SDS concentration, and the...

Conditions for converting a set of five standard proteins to electrochemically active sodium dodecylsulfate (SDS) complexes were worked out with the aim of using such complexes for conductivity detection with a a chip electrophoresis system. The results obtained were compared with standard capillary electrophoresis (37 cm (effective length 30 cm) x 75 microm I.D. capillary, 10 kV, negative pola...

The oxygen scavenging of C-centered radicals in microheterogeneous media was studied by investigation of the photolysis of several ketones (dibenzyl ketone (DBK), oand p-methyldibenzyl ketone (o-MeDBK andp-MeDBK) and d,l-2,4-diphenyipentan-3-one (d,~-DPP)) in oxygen-saturated sodium dodecylsulfate (SDS) micellar solution. The acyland benzyl-type radicals initially formed during the photolysis o...

Aqueous nanoparticle dispersions of a series of three low-band-gap polymers poly[4,8-bis(2-ethylhexyloxy)benzo(1,2-b:4,5-b')dithiophene-alt-5,6-bis(octyloxy)-4,7-di(thiophen-2-yl)(2,1,3-benzothiadiazole)-5,5'-diyl] (P1), poly[(4,4'-bis(2-ethylhexyl)dithieno[3,2-b:2',3'-d]silole)-2,6-diyl-alt-(2,1,3-benzothiadiazole)-4,7-diyl] (P2), and poly[2,3-bis-(3-octyloxyphenyl)quinoxaline-5,8-diyl-alt-thi...

Fracto-eutectogels comprising dendritic fractal aggregates of SDS surfactants in glyceline, a deep eutectic solvent, are observed for the first time, alluding to curious self-assembly mechanisms such H-bonding rich, non-aqueous green solvents.

The persulfate-initiated aqueous emulsion polymerization of 2,2,2-trifluoroethyl methacrylate (TFEMA) is studied by time-resolved small-angle X-ray scattering (SAXS) at 60 °C using a stirrable reaction cell. TFEMA was preferred to styrene because it offers much greater contrast relative water, which essential for sufficient temporal resolution. evolution in particle size monitored both situ SAX...

Several complementary experimental and theoretical methodologies were used to explore water uptake on sodium chloride (NaCl) particles containing varying amounts of sodium dodecyl sulfate (SDS) to elucidate the interaction of water with well-defined, environmentally relevant surfaces. Experiments probed the hygroscopic growth of mixed SDS/NaCl nanoparticles that were generated by electrosprayin...

Spider dragline silk (SDS), the main structural web silk regarded as the “spider’s lifeline", exhibits a fascinating combination of high tensile strength and high extensibility (1). Its toughness is over 10 times that of Kevlar, the material for making bullet-proof suits (2). In addition, SDS has a unconventional sigmoidal shaped stress-strain curve and shape memory capability after the tension...
