We report on the design, construction, and testing of a high-speed rotor intended for use in hypervelocity microparticle impact studies. The is based four-wing design to provide rotational stability includes flat “paddle” surfaces ∼0.5 cm2 at tips each wing. profile wing minimizes variation tensile forces any given speed. was machined using titanium (grade 5) operated high vacuum magnetically l...
the present study involves preparation and evaluation of gastric-mucoadhesive microparticles with metformin hydrochloride as model drug for prolongation of gastric residence time. the microparticles were prepared by the emulsification solvent evaporation technique using polymers of carbomer 934p (c) and ethylcellulose (ec). the microparticles were prepared by emulsion solvent evaporation method...
Experiments were performed using a microparticle image velocimetry (MPIV) for 2D velocity distributions of electroosmotically driven flows in a 40-mm-long microchannel with a square cross section of 200×200 μm. Electroosmotic flow (EOF) bulk fluid velocity measurements were made in a range of streamwise electric field strengths from 5 to 25 kV/m. A series of seed particle calibration tests can ...
objective: this study investigated tissue damages induced by chronic subcutaneous administration of nano- and microparticles of manganese dioxide (mno2) on the liver, kidneys and testes of rats. methods: rats (n=210) were divided into three groups: control, mno2 nanoparticle injected and mno2 microparticle injected. the experimental groups received subcutaneous injections with either nano- or m...
