In this article, the stability of sols detonated nanodiamonds, DND, with positively charged colloidal particles, is studied in different salt solutions water–dimethyl sulfoxide (DMSO) binary systems containing 95 vol.% organic solvent. Additionally, several CCC values are determined acetonitrile for comparison. The critical coagulation concentrations (CCC) using dynamic light scattering techniq...

Nickel ferrite powders were prepared by combustion synthesis of Fe, Fe2O3 and NiO using NaClO4 as fuel. ceramics fabricated single-step two-step sintering under various conditions. The effects each process on the densification, microstructure properties investigated. X-ray diffraction analysis as-prepared as-fabricated confirmed a single-phase NiFe2O4 with cubic spinel crystal structure. Single...

The two-step synthesis of sodium (2,3,5,6-tetrafluorophenoxy) diethane sulfonate (Na-TFP) is reported, starting from 2,3,5,6-tetrafluorohydroquinone as the precursor. Compared with conventional aqueous electrolytes such 0.5 m NaClO4 and Na2SO4, solution Na-TFP provides higher ionic conductivity over a wide range temperature (e.g., >60 mS cm−1 at 20 °C >70 30 °C) wider electrochemical stability ...
