MnZn ferrite precursor powders were prepared by the nano in situ composite method. Three surfactants, which include polyethylene glycol 400 (PEG-400), cetyltrimethyl ammonium bromide (CTAB), and sodium dodecyl sulfate (SDS), usedM impact of surfactants on sol solutions was studied. X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, Raman a field emission scanning electron ...

The interactions of β-lactoglobulin AB in the presence of cationic surfactants such as Cetyltrimethylammonium bromide and Cetyltrimethylammonium p-Toluenesulfonate have been investigated using a variety of experimental techniques such as conductivity, UV-Vis spectrophotometry and fluorimetry. The conductivity of surfactants aqueous solutions with β-lactoglobulin shows that the cmc of cationic s...

Nu-6(1) zeolite, the lamellar precursor of NSI topology, was firstly synthesized with 4'4-bipyridine as the structure-directing agent (SDA) and then subjected to HCl-EtOH treatment for the purpose of structural modification. Interlayer deconstruction and reconstruction took place alternately in this acid treatment. An intermediate named ECNU-4 was separated at the initial stage of this continuo...

Herein, a simple one-step microwave irradiation technique has been used to synthesize the silver nanoparticles using nitrate (AgNO3) solution and cetyltrimethyl ammonium bromide (CTAB) as stabilizing agent. The crystals of as-prepared were studied X-ray diffraction (XRD) selected area electron (SAED) pattern, confirming single-phase face-centered cubic structure. optical property measured UV-Vi...

The dispersion stability and the thermophysical properties of microencapsulated phase change material slurry (MPCMS) for liquid desiccant dehumidification were investigated experimentally. results show that, MPCMS can be improved greatly by adding surfactant. maximum absorbency with polyoxyethylene sorbitan monooleate (Tween80) is 4.1 times that cetyltrimethyl ammonium bromide (CTAB). monolayer...

In this study, monoammonium glycyrrhizinate (MAG) was introduced into cetyltrimethyl ammonium bromide (CTAB)-modified ZnO/attapulgite (APT) via a mechanical process to form performance-enhanced antibacterial nanocomposites (MAG/C–ZnO/APT). The APT supported ZnO nanocomposite (ZnO/APT) prepared by conventional precipitation method, and 20–50 nm of globular nanoparticles were uniformly decorated ...

the reaction between trimethylamine with propargyl bromide was studied and the structure of triethyl propargyl ammonium bromide was illustrated by 1hnmr, ir, and mass spectra.

Superhydrophobic polysilsesquioxane/polystyrene microspheres with raspberry-like to flower-like structure were fabricated via a cetyltrimethyl ammonium bromide (CTAB)-assisted sol–gel approach. The structure of nanoparticles on microcores could be controlled precisely by simply adjusting the content of the silane precursor: with increasing amount of silane precursor, the microspheres transforme...

The United States Pharmacopeia (USP) General Chapters Dissolution 〈711〉 and Disintegration and Dissolution of Dietary Supplements 〈2040〉 allows the use of enzymes in dissolution media when gelatin capsules do not conform to dissolution specifications due to cross linking. Possible interactions between enzymes and surfactants when used together in dissolution media could result in loss of the en...
