DOI: 10.1016/j.apsusc.2018.04.030
Abstract: Abstract It is imperative and challenging to develop environmentally acceptable and cost-effective materials which can readily separate stable emulsions like diesel-in-water emulsion stabilized with surfactants. Thus we attempt to prepare superhydrophobic-oleophilic nano-silica powders with an… read more here.
