In addition, in vitro interaction of MG-63 osteosarcoma cells and PLLA membranes with dense, porous and particulate morphologies was investigated.
In order to assess membrane architecture-related effects on the oxygen transport through ferrite-based mixed conductors, a series of planar ceramic membranes with dense layers made of the dual-phase (SrFeO3 − δ 0.7(SrAl2O4)0.3 composite were appraised at 1023 1223 K under oxidizing conditions.
It was found that a broad molar mass distribution of the polymer in the casting solution is most favourable for the formation of a highly selective membrane with a dense skin and a porous sub-layer.
These results indicate that annealing at an appropriate temperature was important for fabricating a composite membrane with the dense parylene matrix.
The unique feature of the mammalian infective form of African trypanosomes is the plasma membrane with a dense VSG coat.
This contains characteristic hexagonal actin arrays packed between the ER cisterns and the plasma membrane with a dense formation of tubulin fibers adjacent to the ER [ 18, 19].
The advantages of using asymmetric polymeric membranes with a dense skin and a microporous backing for separation of permanent gas mixtures have been p.
LSCF6482 hollow fibre membranes with one dense layer near the outside surface integrated with the highly porous structure showed the highest oxygen fluxes with a maximum value of 34.4 mmol m−2 s−1 under air/He gradient at 1000 °C.
