Biodegradable Polymer Membranes Applied in Guided Bone/Tissue Regeneration: A Review

Polymer membranes have been widely used in guided tissue regeneration (GTR) and guided bone regeneration (GBR). In this review, various commercially available membranes are described. Much attention is paid to the recent development of biodegradable polymers applied in GTR and GBR, and the important issues of biodegradable polymeric membranes, including their classification, latest experimental...

Acid-Functionalized Mesostructured Aluminosilica for Hydrophilic Proton Conduction Membranes

New proton exchange membrane (PEM) materials with high proton conductivities at elevated temperatures (ca. > 150 °C) offer the promise of improving PEM fuel cell operation. Higher operating temperatures would provide several benefits including: (i) improved resistance to carbon monoxide poisoning of the platinum (Pt) electrocatalyst at the anode, (ii) reduced need for feed-stream heat and humid...

Incorporation of sparingly soluble species in mesostructured surfactant-polymer films.

Recently we have investigated the formation of novel thick, solid, mesostructured films of polymer/surfactant mixtures which form spontaneously at the air-solution interface. Here we report studies of the effect of adding a series of sparingly soluble species to the precursor solution, to alter the mesostructure of cetyltrimethylammonium bromide/polyethylenimine films and to investigate the inc...

Production of Polyhydroxyalkanoates, a bacterial biodegradable polymer

There has been considerable interest in the development and production of biodegradable polymer to solve the current problem of pollution caused by the continuous use of synthetic polymer of petroleum origin. Polyhydroxyalkanoates (PHAs) are known to be accumulated as intracellular inclusion in some bacteria. The materials properties exhibited by PHAs, ranging from stiff, brittle to rubber-like...
