Research Progress and Prospects of ZrO2‐Based Catalysts in CO2 Hydrogenation
Carbon and Hydrogen, Volume 27, Issue 4, Page 401-419, November 2025.Herein, we review the multifunctional role of ZrO2‐based catalysts in CO2 hydrogenation to value‐added products, including facilitating H2 dissociation, adsorbed intermediate stabilization, and highly selective C–C coupling while suppressing over‐hydrogenation, which highlights ZrO2 as an active, tunable platform beyond a mere support for efficient ...

Journal of Polymer Science, Volume 63, Issue 21, Page 4525-4536, 1 November 2025.Compatibilization of a HDPE/iPP blend by adding a HDPE‐b‐iPP diblock copolymer leads to formation of core shell structures and restoration of elongation at break in tensile test. ABSTRACT An envisioned circular economy of commonly used polymers, high‐density polyethylene (HDPE) and isotactic polypropylene (iPP), is challenging due to their ...

ChemSusChem, Volume 18, Issue 20, October 23, 2025.Propylene‐ethylene copolymer covalent adaptable networks (PEC CANs) are synthesized via one‐step, radical‐based reactive processing with the use of initiator, dynamic cross‐linkers, and vinyl aromatic additives. The best CAN suppresses over 98% of creep at 100 °C (semicrystalline state) for 10,000 s compared to neat PEC.

THE LICENSING DILEMMA: UNDERSTANDING THE DETERMINANTS OF THE RATE OF LICENSING [PDF]
Licensing entails a tradeoff: licensing payments net of transaction costs (revenue effect) have to be balanced against the lower price-cost margin and/or reduced market share that the increased competition (profit dissipation effect) from the licensee ...

Redox-mediated reactions of vinylferrocene: Toward redox auxiliaries [PDF]
, 2016 Chemical redox reactions have been exploited to transform unreactive vinylferrocene into a powerful dienophile for the Diels–Alder reaction and reactive substrate for thiol addition reactions upon conversion to its ferrocenium state.
