Pretreatment Effects of Conventional and Reactive Extrusion on LLDPE Waste Pyrolysis

Polymer Engineering &Science, EarlyView.
Schematic overview of the pyrolysis study using original and pretreated LLDPE waste samples. Pretreatment was performed via twin‐screw extrusion at 450°C: without additives (REX), with peroxide (REX‐RO2), or with polypropylene (REX–PP). All four samples underwent pyrolysis at 450°C–475°C for 15–45 min.

Computational design of poly(p‐phenylene vinylene)‐based gas sensors: tunable reactivity and selectivity via side‐group functionalization

Polymer International, EarlyView.
Side‐group functionalization enhances the reactivity and optoelectronic properties of poly(p‐phenylene vinylene) (PPV) derivatives for chemical sensing. PPV‐CN and PPV‐NO2 display strong interactions and pronounced responses, providing molecular‐level insights for designing high‐performance polymer‐based sensors.

Photogenerated fluphenazine radical cations for antiviral functionalization of polypropylene masks

Polymer International, EarlyView.
Fluphenazine impregnated into nonwoven polypropylene masks is photoexcited to a radical cation, which inactivates viruses on the polymer surface without causing damage to the masks. Abstract The incorporation of photoactive molecules into polymeric substrates offers a compelling route to introduce advanced functionality while preserving the host ...

Speciation with gene flow

PLANTS, PEOPLE, PLANET, EarlyView.
Biodiversity is threatened by human activities, with extinction debt accumulating rapidly. Many of these activities change the connectivity of populations, fragmenting existing population systems or bringing previously isolated populations or species into contact.
