Enhanced removal of soluble Cr(VI) by using zero valent iron composite supported by surfactant modified zeolites
The Effect of Mixture of AOT Microemulsion with PEG-PPG-PEG Tri-Block Polymer on Surface
The mixture of tri-block polymer with microemulsion on surface is studied with AFM. The study the
topography of surface shows with increase of concentration of polymer, the high distribution doesn’t change but the ...
Sono- synthesis of Core-Shell Nanocrystal (CdS-TiO2) without Surfactant
-shell nanocomposites with small particle size (~11 nm) were synthesized at a relatively low temperature (70oC). The CdS nanoparticles have prepared with a new induced micro-emulsion (O/W) by ultrasound without surfactant and it was easily combined with TiO2 under...
Depletion induced sphere-cylinder transition in C12E5 microemulsion: A Small-Angle X-ray Scattering study.
Small-angle X-ray scattering was used to study the mixture of C12E5 (pentaethylene glycol monododecyl ether)/H2O/n-decane microemulsion and polyethylene glycol (PEG). The size, shape and the structure factor of the ...
Effects of surfactants on nano core-shell particles (Fe₃O₄@TiO): Removal of cationic dye(MB)
employed for removing of MB as a cationic dye. The nanoparticles were synthesized in
the presence of SDS and CTAB which are an anionic and cationic surfactants,
respectively. In fact, the surfactants interact with surface of the shell and modify the...
Study the effect of SDS surfactant on the structural and optical properties of KNbO_3 synthetized by hydrothermal method
In this work, KNbO_3 nanoparticles were synthesized by hydrothermal method at the temperatures in the range of 200 - 250°C. The starting materials were KOH, Nb_2 0_5 anc SDS (Sodium dodecyl sulfate) surfactant. The crystalline structure...
Effect of ultrasound on the chemical stability of alpha-lactalbumin
(20 kHz prob for 15 and 30 min) on stability of α-lactalbumin. The interaction of anionic surfactant, SDS, and cationic surfactant, DTAB, with α-lactalbumin has been investigated in phosphate buffer (pH=7) in the absence and presence of ultrasound...
Surfactant effects on tautomeric and microscopic equilibria of tryptophan: Experimental and theoretical studies
Surfactant molecules are used as interesting tools to study the structure, function and stability of proteins. Protonation states of amino acids may be changed in the presence of surfactants. In this work, using experimental observations...
