文摘
-
Without surfactants, milled Gd2O3 are rough (submicron) particles of various shapes.
-
High sodium dodecyl sulfate (SDS) adsorption on milled grains forms Gd2O3 nanowires.
-
Low cetyltrimethyl ammonium bromide (CTAB) adsorption forms coarser Gd2O3 particles.
-
Surface force arising from surfactants adsorption varies the shape of milled Gd2O3.
-
High SDS adsorbability stabilises the particles via steric and charge balance.
