PURPOSE: We present an analysis of the corneal oxygen consumption Qc from non-linear models, using data of oxygen partial pressure or tension (P(O2) ) obtained from in vivo estimation previously reported by other authors. ...
The modification of Nafion membranes with polyaniline (PAni) has been studied as an alternative for reducing methanol crossover in direct methanol fuel cells (DMFC). The modification has been performed by directly polymerizing ...
Novel nanocomposite membranes were prepared by infiltration of a blend of sulfonated PEEK (SPEEK) with polyvinyl alcohol (PVA), using water as solvent, into electrospun nanolibers of SPEEK blended with polyvinyl butyral ...
Novel polyelectrolyte membranes were prepared from pure solutions of alginate (Alg), carrageenan (Car) and their mixtures. The films were crosslinked and sulfonated and then, characterized by several techniques: ionic ...
The electrospinning approach is an easy and useful method to fabricate porous supports with tailored properties for the preparation of impregnated membranes with enhanced characteristics. Therein, this technique was used ...

PURPOSE. We defined the theoretical oxygen tension behind modern scleral contact lenses (CLs) made of different rigid gas permeable (RGP) materials, assuming different thickness of the tear layer behind the lens. A second ...
This work has been focused on the characterization of the methanol permeability and fuel cell performance of composite Nafion/PVA membranes in function of their thickness, which ranged from 19 to 97 mu m. The composite ...
[EN] Sulfonated poly(ether–ether–ketone) materials (SPEEK) are good proton conductors at high degrees of sulfonation and appropriate for high temperature application due to their glass transition temperatures around 200 ...
[EN] Nanocomposite membranes incorporating electrospun nanofibers of SPEEK, blended with 30 wt% PVB within a water-based matrix of SPEEK with 35 wt% PVA using water as solvent, were prepared and characterized for their ...
This work has been focused on the preparation and characterization of composite membranes with thickness between 19 and 97 mu m and containing Nafion(R) infiltrated into a porous mat obtained by electrospinning of an aqueous ...
[EN] CsH2PO4 is a proton conductor pertaining to the acid salts group and shows a phase transition from monoclinic to cubic phase at 232 +/- 2 degrees C under high-steam atmospheres (>30%). This cubic phase gives rise to ...
[EN] Different crosslinked polystyrene resins containing ionic liquid fragments covalently attached (supported ionic liquid-like phases: SILLPs) have been prepared and their conductivity has been studied by means of ...
