Carbon microbeads were prepared from water-in-oil emulsion using amphiphilic carbonaceous material and urea. With urea as a forming agent with a concentration 1-20 wt.%, hollow carbon-microbeads were obtained, and their particle size ranged between 2 and 15 lam. The true density of the hollow carbon

Several metal colloids stabilized by an amphiphilic copolymer, poly(1-vinylpyrrolidone-co-acrylic acid) (abbreviated as PVPAA), were prepared by refluxing alcohol-water mixed solutions of the corresponding metal precursors. They had small particle sizes and narrow size distributions. Their catalytic
Electrocatalytic electrodes were prepared by coating amphiphilic carbonaceous material containing platinum acetylacetonate from NJ-dimethylformamide on a glassy carbon surface. The electrocatalytic activity of the electrodes was evaluated for hydrogen generation in 1 M hydrogen perchloride by means
