This paper evaluates the compatibility of segmenting fluids for two phase flow applications in biomedical microdevices. The evaluated fluids are chosen due to the variations in fluid properties and cost, while also reflecting their use in the recent literature. These

Different methylphenylsilicone (MPS) and fluorosilicone (FS) oils having a higher specific gravity than water were investigated as vitreous replacements. Their intraocular tolerance in vitrectomized aphakic rabbit eyes was evaluated for periods of up to 4 months and compared to that

In some polymers, in addition to the usual structural alpha relaxation, a slower alpha' relaxation is observed with a non-Arrhenius temperature dependence. In order to understand better the molecular origin of this alpha' relaxation in poly(methylphenylsiloxane) (PMPS) we have studied
