Dinuclear Group 4 Metallocene Catalysts of the Type [(Cp2M)2(μ‐Me)(μ‐C2R)]: Structure‐Activity Relationships in Ethylene Polymerization

Chemistry – A European Journal, EarlyView.
Homo‐ and heterodinuclear group 4 metallocene complexes of the type [(Cp2M)2(μ‐Me)(μ‐C2R)] (M = Ti, Zr) are active catalysts for the polymerization of ethylene in the presence of aluminium‐free activators. The catalytically active species are proposed to have dinuclear character and depending on the type of activator, unique reactivity was observed ...

Theoretical Framework for Predicting Dynamic Covalent Exchange Based on Proton Affinities and Proton‐Transfer Assistance

Chemistry – A European Journal, EarlyView.
Proton‑transfer catalysis controls acylsemicarbazide dissociation, linking proton affinity to exchange kinetics and enabling predictive design of robust, tunable dynamic covalent networks. ABSTRACT We provide design principles for predicting bond exchange kinetics in acylsemicarbazide (ASC)‐based systems that can be applied to tuning the properties of ...

Experimental methods in chemical engineering: The scientific method versus engineering design methodology

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Engineering graduate students confuse the scientific method and problem solving when presenting their pre‐doctoral exams and theses: Science discourse adopts question and hypotheses to assert and establish a study's rationale, while it is problem and objectives in engineering design.
