Acetylene Semi‐Hydrogenation by Photocatalysis

Angewandte Chemie, Volume 138, Issue 40, 28 September 2026.
Photocatalytic acetylene semi‐hydrogenation is an emerging light‐driven route to polymer‐grade ethylene, offering a mild alternative to energy‐intensive thermocatalysis. By replacing H2 co‐feed with water or other proton sources, these systems can achieve high selectivity under ambient conditions.

Electrified Acetylene Removal From Ethylene Streams Enabled by Facet‐Engineered Cu–TiO2 Interfaces

Angewandte Chemie International Edition, EarlyView.
Facet‐engineered interfaces enable selective electrochemical acetylene removal from ethylene streams. Dispersed Cu nanoclusters on the titania {001} facet suppress hydrogen and coupling byproducts, while stabilizing key hydrogenation intermediates.

Influence of THF as Internal‐Donor on Ziegler‐Natta Polyethylene Catalysts

Macromolecular Reaction Engineering, EarlyView.
Ziegler–Natta catalysts remain widely applied due to robustness, handling ease, and cost‐effectiveness. To support further optimization, we examine how internal donors such as tetrahydrofuran influence catalyst performance and polymer characteristics.

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 ...
