We have evaluated the electric characteristics of an organic surfactant material, n-Cethyl-trimethyl-ammonium Bromide (C16TAB) to fabricate the p-n homo-junction. This C16TAB was dissolved in the pure water, where the potassium iodide (KI) was added. The impurities adaptation has been processed in this mixed solution with the application of voltage. The KI is ionized in the water and the potass...

Jewawut merupakan serealia pangan lokal non-beras yang telah lama didomestikasi di seluruh dunia termasuk Sulawesi Barat, Indonesia sebagai alternatif pengganti beras. Ekstraksi DNA tahap awal penting dalam analisis berbasis molekuler. Metode ekstraksi berpengaruh terhadap kualitas dan kuantitasnya dihasilkan program pemuliaan tanaman jewawut. Penelitian ini bertujuan untuk mendapatkan metode e...

The proposed work describes the nanodrop spectrophotometric determination of cationic surfactants using citrate-modified silver nanoparticles based on the aggregation of silver nanoparticles induced by cationic surfactants due to the hydrophobic effect. The visible color change in the solution of silver nanoparticle includes a red shift with the quenching of the absorption spectra. The maximum ...

Dermanyssus gallinae is one of the most serious ectoparasites of poultry and it has been implicated as a vector of several major pathogenic diseases. Molecular detection of such pathogens in mites is crucial and therefore, an important step is the extraction of their DNA from mites. So, we compared four DNA extraction protocols from engorged and unfed individual mites: a conventional method usi...

in this research, the interaction of hexadecyl trimahyl ammonium bromide (htab) with enzyme ureasehas been investigated comprehensively at different experimental conditions such as ionic strength, proteinconcentration using ion selective membrane electrode of surfactants. the obtained binding isotherms frompotentiometnc studies have been analyzed by different theories such as wyman binding pote...

quaternary ammonium compounds (qacs) are employed both as disinfectants for manual processing lines and surfaces in the food industry, and in human medicine area. qacs also cause cell death by protein denaturation . one of the qac is cetyl trimethyl ammonium bromide (ctab) that appears to rapture the cell membrane. the primary site of action of ctab has been suggested to be the lipid components...

poly(styrene-co-butyl acrylate)/clay nanocomposites were synthesized via in situ atom transfer radical polymerization using activators generated by electron transfer in the presence of a montmorillonite ion-exchanged with mixed surfactants of dodecyl trimethyl ammonium bromide and vinyl trimethyl ammonium chloride. the living nature of polymerization is confrmed by occurrence of narrow molecula...

Mesoporous carbon spheres (MCS) have been fabricated from structured mesoporous silica sphere using chemical vapor deposition (CVD) with ethylene as a carbon feedstock. The mesoporous carbon spheres have a high specific surface area of 666.8 m2/g and good electrochemical properties. The mechanism of formation mesoporous carbon spheres (carbon spheres) is investigated. The important thing is a s...
