Journal ArticleDOI
A new technique for the measurement of multicomponent gas transport through polymeric films
TL;DR: In this paper, an apparatus to measure mixed gas permeation through polymer films is described, based on a combination of manometric and gas chromatography techniques, allowing straightforward determination of film permeabilities and selectivities over a wide range of feed pressures and compositions.
Journal ArticleDOI
The use of FTi.r.-a.t.r. spectroscopy to characterize penetrant diffusion in polymers
G.T. Fieldson,Timothy A. Barbari +1 more
TL;DR: In this paper, the diffusion of small molecules in polymers was measured using Fourier transform infra-red-attenuated total reflection (FTi.t.r) spectroscopy, which allows one to study liquid diffusion in thin polymer films in situ.
Journal ArticleDOI
Transglutaminase crosslinked gelatin as a tissue engineering scaffold
Chong Wing Yung,Li-Qun Wu,Li-Qun Wu,Jennifer Tullman,Gregory F. Payne,Gregory F. Payne,William E. Bentley,William E. Bentley,Timothy A. Barbari +8 more
TL;DR: Degradation rates were found to be tunable with gelatin content, an attribute that may be useful for either long-time cell encapsulation or time-released regenerative cell delivery, and investigation showed that proteolytic degradation was controlled by surface erosion.
Journal ArticleDOI
Hydrogel membranes with mesh size asymmetry based on the gradient crosslinking of poly(vinyl alcohol)
W.S Dai,Timothy A. Barbari +1 more
TL;DR: In this paper, a modified version of the multiple-membrane technique was used to determine boundary layer resistance in order to determine the intrinsic membrane permeability, which indicates that creating mesh size asymmetry in a hydrogel can result in a high-flux, high-selectivity membrane for cell encapsulation or bioseparations.
Journal ArticleDOI
Polymeric membranes based on bisphenol-A for gas separations
TL;DR: In this paper, the effect of the connecting group between bisphenol-A units on the gas separation characteristics of membranes formed from these polymers was examined and an unusually high He/CH4 selectivity was noted for one of the members in the series of polymers.
