Modifying Mechanical Performance of an LLDPE/PP Waste Blend During a Single Recycling Cycle Using Organometallic Complexes

open access: yesSPE Polymers, Volume 7, Issue 1, January 2026.
High‐shear processing combined with low‐level (0.05 wt%) organometallic complexes improves the impact strength of PE/PP recyclates by up to 50% while maintaining tensile properties. ABSTRACT In this study, organometallic complexes were introduced at 0.05 wt% to modify the performance of a 70/30 LLDPE/PP waste blend during a single recycling cycle under

Triple Calcium Binding Stoichiometry in the Monoclinic Crystal Form of Protracted Insulin

open access: yesSmall Structures, Volume 6, Issue 12, December 2025.
Crystallographic analyses reveal insulin hexamers coordinated by three Ca2+ ions within the GluB13 cavity, visualized in monoclinic crystals at cryogenic and ambient conditions. This unique binding stabilizes the R6 state through inter‐subunit coordination while preserving canonical Zn2+–HisB10 interactions.
