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 ...

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...

Glyphosate affects ecosystems due to exposure of non-target crops and is a persistent contaminant at low concentrations. The application palygorskite reduce glyphosate contamination in Brazil an environmentally friendly way remediate impacted areas. This research evaluated for adsorption present synthetic effluent. Palygorskite samples were ore dressed by wet granulometric classification magnet...

Pyridine-4-carboxylic acid hydrazide, commercially known as isoniazid (INH), is an antitubercular drug and is now widely used together with rifampicin and streptomycin for the chemotherapy of tuberculosis. Ritodrine hydrochloride (RTH), chemically, 1-(4-hydroxyphenyl)-2-[2-(4-hydroxyphenyl)ethylamino]propanol is a potent tocolytic drug and is a selective β2-adrenoceptor agonist and is used to c...

The forces between a flat gold surface and a gold-coated silica sphere have been measured in water using an atomic force microscope. A long-range attractive interaction is observed which is ascribed to the van der Waals interaction between the two surfaces. The force data agree extremely well with recent, calculated values of the Hamaker function (including retardation) for gold/water/gold. The...

Binding studies of cationic detergents such as cetyltrimethyl ammonium bromide, Cetyl pyridinium bromide and dodecyl trimethyl ammonium bromide with β Lactoglobulin were carried out by equilibrium dialysis, ultraviolet difference and circular dichroism techniques at 25 C. Binding isotherms at pH 5·0, 7·0 and 9·0 show cooperative binding at all concentrations of detergents and the number of avai...

A simple and accurate label-free amperometric immunosensor for α-fetoprotein (AFP) detection is developed based on gold nanorods (GNRs) with different aspect ratio and compared with gold particles (GNPs). The positively charged GNRs and GNPs due to the surface immobilized cetyltrimethyl ammonium bromide (CTAB) can adsorb the negatively charged AFP antibody (Ab) directly. The presence of the GNR...

Solutions of rodlike polymeric micellar aggregates, formed from the polymerization of cetyltrimethyl-ammonium 4-vinylbenzoate (CTVB), adsorb at the solid-liquid interface. The poly-CTVB aggregates are imaged in situ using soft contact atomic force microscopy. The aggregates form self-organized two-dimensional films that show a high degree of order on nanometer to micrometer length scales. Unlik...
