Modeling and Optimization of propylene polymerization with branching [PDF]
, 2014 A kinetic model has been proposed to fit the experimental data (2003) available from the open literature for branched propylene polymerization system. The present system considered is a binary catalyst system, in which the first catalyst produces the ...

Catalytic N_2-to-NH_3 Conversion by Fe at Lower Driving Force: A Proposed Role for Metallocene-Mediated PCET [PDF]
, 2017 We have recently reported on several Fe catalysts for N_2-to-NH_3 conversion that operate at low temperature (−78 °C) and atmospheric pressure while relying on a very strong reductant (KC_8) and acid ([H(OEt_2)_2][BArF_4]). Here we show that our original
