Water transport through nanocomposite-based polyamide 12/montmorillonite was investigated by permeation kinetics. Intercalated and semi-exfoliated nanocomposite structures were studied. For low montmorillonite content (£ 5%) a decrease of water permeability was obtained for a both structures and mai

In the present work the metal-ceramic catalytic membranes with gradient porosity in the range of 2–3000 nm pore size were obtained. Proposed structural design of membranes including the combination of catalytic coatings inside of membrane channels with a top coating of a mesoporous metal oxide layer

Acknowledgment This work was carried out also with the contribution of RENCO S.p.A (Italy).

Ultimately, PNIPAAm systems were identified which could effectively and reversibly block water flow even through the largest Effective hydrodynamic layer thickness, lh (nm) Effective hydrodynamic layer thickness, lh (nm) y = 15.9x y = 9.6x y = 1.0x y = 1.3x Estimated dry layer thickness, lgr (nm) PE

PEEK-WC HF bioreactor permits us to reproduce the Hypericum perforatum immunomodulatory effect on human peripheral lymphocytes as observed by previous in vivo studies. In fact, St. John’s wort modulates linfocitary response suppressing metabolic activities. This investigation underlines the ability

The unique feature of molecularly imprinted membranes is the interplay of selective binding and transport properties, making them potentially superior to state-of-the-art synthetic separation membranes already applied in various biological and biomedical fields [1]. Adsorption capability and transpo

The efficient design of a membrane bioreactor for cells culture needs the complete characterization — both experimentally and theoretically — of the transport phenomena for metabolites, catabolites, cell regulatory and immune-related soluble factors. In this work, experiments and theoretical calcula

Capsules of PEEKWC are prepared using a membrane process combined with phase inversion technique. Polymeric droplets were prepared using a mono-pore film in polyethylene with pore diameter ranging from 300 to 1000 mm. The morphology, porosity and shell thickness of the made capsules are modified cha

The organic filler TMSG was incorporated into the two glassy polymers PTMSP and EC, resulting in reversed effects on their gas permeability. For PTMSP the reduction of permeability with filler content was far higher than the theoretical prediction (Maxwell equation) for the addition of impermeable f
