Inter‐Crystal Spacing of Implantable Polymeric Surfaces as a Key Suppressor of Microbial Adhesion.

Small, EarlyView.
Biofilm formation on implantable devices is addressed by controlling inter‐crystal spacing in shape memory polymers. Repeated shape recovery aligns and enlarges crystalline phases and reduces amorphous regions, enhancing bacterial repellency. Three biofilm‐forming bacteria show reduced adhesion, and a one‐year dog bile‐duct model maintains function ...

Processing Stabilization of Polyolefin Recyclates Using Alditols in Combination With α‐Tocopherol: A Sustainable Alternative to Phosphites

Journal of Vinyl and Additive Technology, EarlyView.
A novel bio‐based stabilizer system significantly improves the quality of polyolefin recyclates during multiple recycling cycles. ABSTRACT This study introduces a novel bio‐based stabilizer system for polyolefin recyclates that combines alditols with small amounts of α‐tocopherol as a sustainable alternative to conventional phosphite additives. The aim
