A non-binding surface demonstrates increased thrombogenicity under plasma-free conditions [PDF]

open access: yesScientific Reports
Although the commercially available, non-binding microplate is characterised as a low-fouling material, its suitability for the study of platelet function in basic research has yet to be determined.

Upcycling Polystyrene

open access: yesPolymers, 2022
Several environmental and techno-economic assessments highlighted the advantage of placing polystyrene-based materials in a circular loop, from production to waste generation to product refabrication, either following the mechanical or thermochemical routes.

Photochemical Upcycling/Modification of Polystyrene-based Plastic Waste

open access: yesCHIMIA, 2023
The escalating accumulation of plastic waste in landfills and marine environments has become a pressing concern to society. Among all plastic-based waste, polystyrenes are widely utilized as a commodity plastic and present very low recyclability.

A short review of the photomechanical effect in azo-containing amorphous (glassy) polymers

open access: yeseXPRESS Polymer Letters, 2021
The photomechanical effect has been studied so far mainly in elastomers, but recently more and more publications, in which this effect is studied for other materials too, so-called glassy or amorphous polymers (in particular polyimides), have appeared ...
