12. Hemocompatible nanostructured membranes for artificial organs

Dr Mónica Faria

Artificial Organs are generally associated to clinically well-established membrane-based treatments that assure in extracorporeal blood circulation devices the separation functions of a failing organ like the hemodialyzer (HD) for the kidney or the membrane blood oxygenator (MBO) for the lungs.
Current available medical devices used in these treatments are implicated with severe long-term...

13. Tailoring asymmetric structures of cellulose acetate/silica membranes for the artificial kidney

The cellulose acetate (CA) membranes, developed in the early 1960s by Loeb and Sourirajan [1] for sea water desalination,
are prepared by the wet phase inversion method [2] which is responsible for creating an asymmetric structure. The structure
is composed of a thin skin dense layer that determines the membrane selective characteristics and a porous sublayer which
provides mechanical...

14. Modeling of macro-cryoconcentration phenomena during the freezing of bio-pharmaceutical aqueous solutions

Modelling unstirred freezing of aqueous solutions with volumes between few millilitres and hundreds of litters is very useful in a multitude of applications. Aqueous solutions are frozen, for instance, in the food or biopharma industries to preserve the main ingredients. In these two applications, the quality of the frozen product depends on the adequate design of the freezing systems. To get...
