Polyurea microcapsules in microfluidics: surfactant control of soft membranes.
Interfacial polymerization techniques offer a versatile route for microcapsule synthesis. We designed a microfluidic process to synthesize monodisperse polyurea microcapsules (PUMCs); the microcapsules are formed by an interfacial polymerization of isocyanate dissolved in the oil and an amine dissolved in water. We measure the mechanical properties of the capsule as well as transport properties...
متن کاملControlling the morphology of polyurea microcapsules using microfluidics.
We use microfluidics to continuously produce monodisperse polyurea microcapsules (PUMCs) having either aqueous or nonaqueous cores. The microcapsule shells are formed by the reaction between an isocyanate, dissolved in oil, and an amine, dissolved in water, at the surface of oil-in-water or water-in-oil drops immediately as they are formed. Different microcapsule morphologies can be generated u...
متن کاملPopulations of Rice Grain Bug, Paraeuscosmetus pallicomis, (Hemiptera: Lygaeidae) in Weed-free Paddy Field, Weedy Paddy Field and Paddy Dykes
Research on the populations of rice grain bug Paraeuscosmetus pallicomis Dallas (Hemiptera: Lygaeidae) in paddy field ecosystems was performed with the aim to determine the populations of rice grain bug in weed-free paddy field, weedy paddy field, and paddy dykes. Experiment was carried out in the village of Paccellekang in the district of Patallasang of Gowa Regency in South Sulawesi, Indonesi...
متن کاملOptimization of encapsulation conditions of chlorpyrifos microcapsules
With UF-resin as wall material, chlorpyrifos microcapsules was prepared by in-situ polymerization. The effect factors on the particle size and encapsulation efficiency of microcapsules were investigated and optimized. The result showed when the mass concentration of the emulsifier Tween-20 was 6%, the size of chlorpyrifos microcapsules were suitable. The amount of UF-resin has slight effect on ...
متن کاملInvestigation of Spatial Distribution of Radiocesium in a Paddy Field as a Potential Sink
Surface soils, under various land uses, were contaminated by radionuclides that were released by the Fukushima Daiichi Nuclear Power Plant accident. Because paddy fields are one of the main land uses in Japan, we investigated the spatial distribution of radiocesium and the influence of irrigation water in a paddy field during cultivation. Soil core samples collected at a paddy field in Fukushim...
