Oil-in-water nanoemulsions are stable systems with droplet sizes in the 20-200 nm range. The physicochemical properties of these systems may be influenced by the addition of additives. Thus, the influence of ethoxylated (EL) and acetylated lanolin (AL) addition on the droplet size, pH values, electrical conductivity and stability of nanoemulsions was investigated. Then, effect of nano-emulsions...

We have prepared and characterized a series of nonfluoro polymer composites with functional carbon additives such as graphite, candle soot and camphor soot which when mixed with EPF (Expanded Polystyrene Foam) matrices increase surface hydrophobicity. Water contact angles of >150° was observed on spin-cast composite film surfaces containing 3% camphor soot particles, compared to 89° in the abse...

We report on the sintering of powders chalcogenide perovskite BaZrS3 at low and intermediate temperatures. is most widely studied semiconductor. Most experimental results to-date have been made using loose powder cold-pressed pellets (i.e. green bodies). Straightforward methods to achieve dense ceramics are challenging because decomposes oxidizes in air above 550 °C. Here, we take inspiration f...
