Green polyurethanes from bio-based building blocks: Recent advances and applications
Green Synthesis and CatalysisPolyurethanes (PUs) are among the most studied, manufactured, and employed polymers due to their versatility and wide range of applications. However, their synthesis generally relies on toxic, non-renewable, and harmful petroleum-based chemicals.

Ricinusovo ulje kao obnovljiva sirovina za dobijanje poliuretanskih materijala [PDF]
, 2016 Traditionally, polyurethanes (PU) are manufactured by reacting isocyanates with petroleum-based polyols (polyether or polyester). Because oil resources are diminishing and are becoming expensive to produce, engineers and scientist have discovered new ...

Advanced Healthcare Materials, EarlyView.Our coaxial electrospinning system is capable of incorporating decellularized myocardial extracellular matrix in a core‐sheath configuration, creating nanofibrous scaffolds. These scaffolds, in turn, support the maintenance of functional cardiomyocytes adhered to the surface of these bioactive scaffolds.

Design and Synthesis of Peptide‐Polyester Conjugates for Cell‐Mediated Scaffold Degradation
Advanced Healthcare Materials, EarlyView.This work describes polycaprolactone (PCL)‐based biomaterials engineered to degrade in response to cell‐secreted proteases. A fast‐degrading peptide (Fast) sequence is integrated into a PCL conjugate backbone to produce a biomaterial that is selectively degraded by multiple cell types compared to its scrambled control (ScrFast).
