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

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

Diffusion in cell membranes is not just simple two-dimensional Brownian motion but typically depends on the timescale of the observation. The physical origins of this anomalous subdiffusion are unresolved, and model systems capable of quantitative and reproducible control of membrane
