Aqueous dispersions of hydrophobic high-molar-mass cellulose-graft-polystyrene (Cel-g-PS) copolymers were prepared by nanoprecipitation from dioxane solutions using sodium dodecyl sulfate as a stabilizer. The size and structure of formed Cel-g-PS nanoparticles were studied by scattering techniques (static and dynamic light scattering, SAXS) and transmission electron microscopy. The scattering a...

A micellar thin-layer chromatographic system comprising of silica layer impregnated with 0.01% sodium dodecyl sulphate (SDS) as stationary phase and 0.1% aqueous solution of Cween 80 as mobile phase was identified as the most favorable system for the mutual separation of five water-soluble vitamins (folic acid, cyanocobalamin, thiamine, pyridoxine, and riboflavin). Effects of the presence of me...

Bandgap modulation of single-walled carbon nanotubes (SWCNTs) can be achieved by encapsulation of metallofullerenes, covalent functionalization or changing the tube aggregation states. Another attractive idea is to dope SWCNTs by adding electron donors or acceptors since it allows us to control their electronic states without generating defects in the SWCNT bonding structures. Reversible doping...

1. Comparative study of carbon nanotube dispersion using surfactants Aqueous carbon nanotube dispersions were obtained by sonication tip using two cationic (DTAB and CTAB) and three anionic surfactants (SDDBS, SDS and SC). UV-Vis spectroscopy is a versatile method for characterizing the dispersion quality of CNTs in a solution. Bundles of MWCNTs are not active in the wavelength region between 2...

The data presented in this article are related to the research article entitled Structure of Self-assembled Native Soy Globulin in Aqueous Solution as a Function of the Concentration and the pH by N. Chen, M. Zhao C. Chassenieux, T. Nicolai (2016) [1]. Please refer to this article for interpretation of the data. The protein composition of soy protein isolate (SPI) was characterized by SDS-Page....

A fundamental study about the selective foam separation of protein mixture was carried out. A solution containing two proteins, Ovalbumin (OA) and Lysozyme (LZ), and an anionic surfactant, Sodium Dodecyle Sulfate (SDS), was adjusted to pH 6.0 which refered to an intermediate state between the isoelectric points of the proteins. The solution was processed by continuous foam separation. The resul...

Antiviral proteins were isolated, from host plants, following treatment with an antiviral glycoprotein, extracted from the roots of Boerhaavia diffusa plants. It was found to be active against isometric as well as an isometric viruses in their respective hypersensitive and systemic hosts. The biologically active principal was isolated and purified. Estimation of proteins, from the leaf samples ...

In order to use a simple and ecofriendly method to prepare porous silk scaffolds, aqueous silk fibroin solution (ASF) was extracted from silk gland of 7-day-old fifth instar larvae of Bombyx mori (B. mori). SDS-page analysis indicated that the obtained fibroin had a molecular weight higher than 200 kDa. The fabrication of porous scaffolds from ASF was achieved by using the freeze-drying method....

Complexation of thiazorylazododecylphenol (TADP) with Ni2+ at the surface of sodium dodecylsulfate (SDS) micelles has been spectrophotometrically studied. Complicated spectral changes are analyzed by a factor and multivariate analysis, which implies the formation of [TDAP(OH-)Ni]0 as well as a simple 1:1 complex of Ni2+ with TDAP at the micellar interface. All of the equilibrium constants requi...
