Synthesis and potential application of Fe3+/Mn2+ bimetal and hexadecyltrimethylammonium bromide (HDTMA-Br) modified clayey soils for arsenic removal in groundwater
The presence of arsenic in groundwater has drawn worldwide attention from researchers and public health officials due to its effects on human health such as, cancer, skin thickening, neurological disorders, muscular weakness, loss of appetite and nausea. World Health Organisation (WHO) has set the …

A study on wettability properties of rutile-phase TiO2 nanostructure film
… volume of TBOT as well as the use of surfactant hexadecyltrimethylammonium bromide (HTAB) toward the synthesis growth of nanorods are thoroughly evaluated. The samples are analysed by using X-Ray Diffraction (XRD) for structural properties, Field Emission Scanning Electron Microscopy (FE-SEM) for …

THE INFLUENCE OF SURFACTANTS ON THE SORPTION OF PHENANTHRENE IN NATURAL WATERS
… Triton X-100, sodium dodecyl sulphate (SDS) or hexadecyltrimethylammonium iodide (HDTMA) proved to be highly complex. The adsorption, expressed as a Freundlich coefficient, KF was generally nonlinear and varied according to surfactant type, salinity, temperature, and contact sequence. The …

BIOCHEMICAL AND MOLECULAR CHARACTERIZATION OF RAFFINOSE FAMILY OLIGOSACCHARIDE (RFO) BIOSYNTHESIS IN LENTIL (Lens culinaris Medik.)
… purity and/or in adequate quantity. A CTAB (hexadecyltrimethylammonium bromide) based RNA isolation procedure with lithium chloride precipitation yielded RNA in adequate quantity (210 - 260 μg from 200 mg of seeds) and required purity (A260 / 280 ratio of about 2.2). The optimized RNA …

Sensing Applications of Silver and Gold Nanoparticles
… Ag cubes. We also functionalized the cationic hexadecyltrimethylammonium bromide (CTAB)-stabilized Au NRs with anionic poly(sodium 4-styrenesulfonate) (PSS). Coated with the strong polyelectrolyte PSS, the NRs become more manageable and can be stable for over six months and are easily …
