Stepan's dry CaDDBSA co-formulant for agricultural applications is in the running for the 2022 Independent Commodity Intelligence Services (ICIS) Sustainability Award for its positive contribution to improving sustainability in the industry.
The exceptional stability of Pd2+ ions in square-planar oxygen environment in CeO2 materials is also claimed in other experiments [6,27,32]. Note that CO adsorption on all Pd-containing models does not change the oxidation state Pd2+, except for Pd1c with an endothermic mode by 0.13 eV ...
