Recyclability of Polystyrene Bead Foams: Degradation Behavior over 10 Extrusion Cycles

Polymer Engineering &Science, EarlyView.
This study investigates the multi‐cycle recycling of expanded polystyrene bead foam blended with virgin material. Material degradation is monitored by MFI, GPC, and mechanical testing. The results demonstrate that long‐term recyclability is feasible without progressive property loss, and that secondary high‐shear steps such as extrusion and pelletizing

Atomic‐Scale Insights Into Antisite‐Defect‐Induced Metallicity in Halide Perovskites

Small, EarlyView.
Using an aberration‐corrected scanning transmission electron microscope, we identify that the PbCs antisite defect in CsPbBr3 shortens the Pb─Pb bond by ∼20 pm, and induces local strain and polarization, leading to a semiconductor‐to‐metal transition.
