Predicting Product Distribution of Propene Dimerization in Nanoporous Materials

Berend Smit

In this work, a theoretical framework is developed to explain and predict changes in the product distribution of the propene dimerization reaction, which yields a mixture of C-6 olefin isomers, resulting from the use of different porous materials as cataly ...

Morphology stabilization strategies for small-molecule bulk heterojunction photovoltaics

Kevin Sivula, Liang Yao, Xavier Adrian Jeanbourquin, Simon Hänni, Arvindh Sekar, Emilie Aude Marie Ripaud, Muhammad Aiman Bin Rahmanudin Hamdan

The greater crystallinity of solution-processed small-molecule organic semiconductors, compared to their polymer counterparts, renders the bulk heterojunction (BHJ) more susceptible to phase separation under thermal stress, decreasing device performance. H ...
