Admicellar Polymerization Of Calcium Carbonate And Its Performance In Drilling Fluids
Admicellar polymerization using sodium dodecylsulfate (SDS) template to form ultrafilm polystyrene on commercial calcium carbonate (CaCO3 ) of various particle sizes was studied. Adsorption isotherms of SDS decrease after the critical micelle concentration (CMC) of SDS was observed. This is …

Detection of Unique Tumor-Associated Proteins in the Urine of Patients with Transitional Cell Carcinoma by High Resolution Two-Dimensional Polyacrylamide Gel Electrophoresis
… focusing in the first dimension and sodium dodecylsulfate - polyacrylamide gel electrophoresis in the second dimension. Ten transitional cell carcinoma patients, ten renal cell carcinoma patients, two benign bladder patients, two benign kidney patients, and seven normal donors were included …

Liquid foams of graphene
… foaming agents, such as the commonly used sodium dodecylsulfate, are surfactant molecules with linear or branched chain molecular structures. This thesis presents a new class of liquid foams made with a foaming agent having a sheet molecular structure. In these foams, air bubbles are encapsulated …

Reversed-Phase HPLC Determination of Alliin in Diverse Varieties of Fresh Garlic and Commercial Garlic Products.
… use of 30:70% methanol: water and 0.05% sodium dodecylsulfate mobile phase composition, C<sub>18</sub> 5 μm disc column of size 3.9 x 150 μm, and detector set at 210 nm. The method showed good reproducibility with 0.56%-4.11% relative standard deviations, a linear response of peak area to …

A Putative Cytosolic Saxitoxin Binding Protein in Frog Myocardium
… vesicle proteins which are resolvable by sodium dodecylsulfate polyacrylamide gel electrophoresis (SDS-PAGE) using 7.5% acrylamide disc gels are found in the aqueous supernatant (F1 fraction) when the dialysate is centrifuged at 100,000 xg for 1.5 hours. The yield of the individual proteins in F1 …

Improvement of carbon nanotube-based field-effect transistors by cleaning and passivation
… chemical removal of surfactant residues (sodium dodecylsulfate) from CNTs, integrated using the dielectrophoretic approach, by investigation and comparison of four procedures (de-ionized water, HNO3, oDCB, Ethanol); b) the reduction of process-related substrate contaminations by application of an …

Micelle Enhanced Analytical Chemistry
… systems (sodium decylsulfate (NaDS), sodium dodecylsulfate (SDS) and sodium tetradecylsulfate (NaTDS)). The presence of these anionic micellar systems enhanced the Stern-Volmer quenching constant, K<sub>SV</sub>, relative to that observed in water alone (by a factor of ca. 80 for SDS as the …

Azido Auxins: Synthesis and Use as Photoaffinity Labeling Agents
… acid, migrate as four bands in sodium dodecylsulfate polyacrylamide electrophoresis with apparent molecular weights of 60, 49, 45, and 37 kilodaltons. These proteins focus as at least five bands in isoelectric focusing gels with apparent isoelectric points of 4.8, 5.0, 5.1, 5.2, and …

Controlling molecular interactions to define interfacial phenomena and structure
… and small molecule surfactants, SMS, (sodium dodecylsulfate, SDS or C12SO4Na, dodecyltrimethylammonium bromide, C12TAB and polyoxyethylene (23) lauryl ether, Brij 35) in the presence of alcohols (ethanol, hexanol and decanol). The composition of the mixed micelles formed was found to be …

Influence of hydrophobically modified polyelectrolytes on nanoparticle synthesis in self-organized systems and in water
… has been made with the anionic surfactant sodium dodecylsulfate (SDS) and the cationic surfactant cetyltrimethylammonium bromide (CTAB) since they can interact with the oppositely charged polyelectrolytes and the microemulsions formed using these surfactants present a large water-in-oil region. …

Proteinpolysaccharides from Bovine Nasal Cartilage Interactions with Glycoproteins and the Formation of Aggregates
… and by protein denaturants such as 1% sodium dodecylsulfate or 6 M urea. Aggregation is irreversibly abolished when cystine residues within the proteins are reduced. Although sulfhydryl reducing agents and low solvent pH prevent aggregation, they are not sufficient conditions to allow GPL to …

Effect of Non-Ionic Surfactants and Nano-Particles on the Stability of Foams
… the presence of a mixture of C12EO8 and sodium dodecylsulfate (SDS) at different ratios. The results showed that the hydrophobic force increased with increasing C12EO8 to SDS ratio. Thus, the former was more effective than the latter in decreasing the hydrophobic force and hence stabilizing foam …

Synthesis, properties and applications of single-component anion-exchange materials
Several tetraalkylated ferrocenium salts and neutral modified ferrocenes, both new and previously synthesized, were studied in detail. Some of these salts have been used in the past as anion-exchange extractants for attenuated total reflectance-Fourier transform infrared (ATR-FTIR) spectroscopy. …

Electrically Controlled Formation and Release of Admicelles for Solid Phase Extraction
<p>Solid phase extraction is one of the most widely used methods to concentrate diluted compounds in a solution. Substances can be extracted into admicelles and hemimicelles, which are surface adsorbed micelles and surfactant monolayers, respectively. Investigations of the electrical control of …
