We introduce a novel approach for synthesizing mesoporous hydroxyapatite (HAp, (Ca)10, (PO4)6(OH)2) using double emulsion droplets as microreactors. By using capillary microfluidic techniques, the size and the geometry of the droplet microreactors can be tuned easily. Double emulsion droplets offer the combined advantages of both shielding the reactants and on-demand addition of reactants; this...

We report a parallelized capillary microfluidic device for enhanced production rate of monodisperse polymersomes. This device consists of four independent capillary microfluidic devices, operated in parallel; each device produces monodisperse water-in-oil-in-water (W/O/W) doubleemulsion drops through a single-step emulsification. During generation of the double-emulsion drops, the innermost wat...

Crystallization phenomena of organic soft materials occurring in template-controlling systems such as emulsions, vesicles, micelles and air-water interfaces have been discussed by reviewing recent work. Long-chain molecular crystals and amino acids were chosen as the model substances of the organic soft materials which are key materials in food, pharmaceutical, nuetraceutical, cosmetic, and oth...

Localization of tritium label in bacteria has been successfully demonstrated both at the intercellular level (1) and at the intracellular level (2). However the use of Kodak AR-10 (3) stripping emulsion gives rise to a complication in those experiments. The 2 # maximum range (4) of the/3-rays from tritium in this emulsion, plus the greater than 2 # thickness of the stripping emulsion itself, co...

Polymer-modified bitumen emulsions present a safer and more environmentally friendly binder for enhancing the properties of roads. Cationic bitumen emulsion binders containing polymer latex were investigated using confocal laser scanning microscopy. The latex was incorporated into the bitumen emulsion by using four different addition methods and all emulsions were processed with a conventional ...

During recent decades due to the increase in pollutants release from various industries, reduction or elimination of volatile organic compounds VOCs has become one of the main purposes of researches in order to protect the environment. In this research, two acrylic emulsion resins and an adhesion promoter polyester emulsion resin were used to optimize water-based printing ink formulation for pr...

A simple and robust co-flowing microfluidic device for double emulsion preparation is designed and assembled to visually study the double emulsion formation by the use of a microscope and high-speed camera. Using a visualization system, the transient processes of double emulsion formation in co-flowing stream are observed and recorded for a variety of flow rates. The effects of flow rates of ea...

We demonstrate a simple, low-cost, and green approach to deposit a microstructured coating on the silicone elastomer polydimethylsiloxane (PDMS) that can be coated with gold to produce highly stretchable and conductive films. The microstructured coating is fabricated using an aqueous emulsion of poly(vinyl acetate) (PVAc): common, commercially available white glue. The aqueous glue emulsion sel...
