A Unified Model Explaining Heterogeneous Ziegler-Natta Catalysis [PDF]

, 2015
We propose a model for MgCl2 supported Ziegler-Natta catalysts capable to reconcile the discrepancies emerged in the last 20 years, when experimental data were tried to be rationalized by molecular models.

Extensional Rheology and Extrusion Blow Molding of Idealized High‐Density Polyethylene/Polypropylene Blends as Model Post‐Consumer Resins

Journal of Polymer Science, EarlyView.
Compatibilization markedly improves the top‐load compression performance and structural integrity of HDPE/PP blow‐molded bottles. Neat HDPE, PP, and HDPE/PP bottles exhibit premature neck cracking at relatively low strains, whereas the compatibilized HDPE/PP/C blend sustains substantially higher loads and greater deformation without cracking ...

Role of 1D and 2D Materials in Achieving Transparent and Flexible Lithium‐Ion Batteries for Wearable Electronics

Small, EarlyView.
Hybrid 1D–2D architectures redefine material design strategies for TFLIBs by decoupling competing performance parameters. This approach accelerates the transition of TFLIBs from proof of concept to practical wearable technologies. ABSTRACT Transparent and flexible lithium‐ion batteries (TFLIBs), enabled by advanced nanomaterials and flexible ...
