Fundamental understanding of the material science and rheological engineering to fabricate Torlon® 4000T-MV and 4000TF hollow fiber membranes with an ultra-thin and defect-free dense-selective layer for gas separation has been revealed.
The effect of the electrical double layer (EDL) on the DEP separation has also been considered in this study.
"Separation" has become a buzzword.
Two, the separation has to be effective.
Update: Philae's separation has now been confirmed.
Although an increase in source-detector separation has been reported to enhance depth sensitivity [ Dehghani et al., 2009], mathematical models to increase the sensitivity for deep layer/tissue have also been proposed to benefit the image quality of DOT.
The concept of a new control system which may be used in practice, based on a radiometric density meter with a properly collimated radiation beam and located at the level of the separation layer has been discussed.
But separation had been hard, he admitted.
Composite membranes with an ultra-thin polyimide separation layer have been prepared by the deposition of dimethylalkylammonium salt of polyamic acid on a poly phenylene oxide) porous support layer by the Langmuir Blodgett technique and subsequent thermal cyclization of the polyimide precursor.
