Effect of Radical Initiators on the Rheological Properties and Toughness of Poly(Lactic Acid)/Poly(3‐Hydroxybutyrate‐Co‐4‐Hydroxybutyrate) Blends

open access: yesPolymer Engineering &Science, EarlyView.
Effect of mixing protocol on the size distribution of PHA domains in the PLA matrix. ABSTRACT In this study, poly(lactic acid) (PLA) and poly(3‐hydroxybutyrate‐co‐4‐hydroxybutyrate) [P(3HB‐4HB), a type of polyhydroxyalkanoate (PHA)], were melt‐blended at an 80/20 (wt/wt) ratio, and radical initiators were employed as reactive compatibilizers to enhance

Effect of Accelerated Aging on the Performances of 3D Printed Polylactic Acid‐Polyhydroxyalkanoate Specimens

open access: yesPolymer Engineering &Science, EarlyView.
The accelerated aging behaviours on the FFF‐fabricated PLA‐PHA Specimens. ABSTRACT Despite the increasing use of biodegradable polymers in additive manufacturing, their long‐term durability remains insufficiently understood. The aim of this study to investigate the influence of accelerated aging on the performance of fused filament fabrication‐printed ...

Robust β‐myrcene block copolymer elastomeric vitrimers

open access: yesPolymer International, EarlyView.
Myrcene‐based vitrimeric elastomers were compared: statistical (poly(styrene‐stat‐myrcene‐stat‐AAEMA)] versus ‘hard–soft’ diblock (poly(styrene)‐block‐poly(myrcene‐co‐AAEMA)). The diblock's ability to anchor the glassy poly(styrene) blocks in a self‐assembled microstructure was effective – leading to four times higher tensile stress and ten times ...

Interactive effects of microplastics and arbuscular mycorrhizal fungi on grassland communities

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Grassland plant communities contribute significantly to global biodiversity but face numerous man‐made pressures which may interfere with their ecological functions. One such pressure receiving increasing scientific, political, and public attention is microplastic pollution.

Effects of autoclave sterilization on the dimensional stability of implant surgical guides: A 3D in vitro analysis

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose Surgical guides are medical devices used in static implant surgery to replicate the prosthetic and surgical implant position planned with computer‐assisted software before surgery. Their use reduces invasiveness and improves safety and outcomes of implant surgery, provided that their accuracy is ensured from design to manufacturing and
