Polyurethanes (PUs) are an exceedingly heterogeneous group of plastic polymers, widely used in a variety industries from construction to medical implants. In the past decades, we have witnessed accumulation PU waste and its detrimental environmental impacts. PUs been identified as one most toxic polymers leaching hazardous compounds derived both polymer itself additives production. Further impa...

Reconstruction of the human auricle remains a challenge to plastic surgeons, and current approaches are not ideal. Tissue engineering provides a promising alternative. This study aims to evaluate the chondrogenic potential of bone marrow-derived mesenchymal stem cells on a novel, auricular-shaped polymer. The proposed polyhedral oligomeric silsesquioxane-modified poly(hexanolactone/carbonate)ur...
