Methylaluminoxane (MAO) is one of the most commonly utilized co-catalysts in the single-site production of polyolefins catalyzed by metallocenes. However, its exact structure has eluded experimental characterization because of the dynamic equilibrium between various species...
In a recent Chemical Reviews paper researchers from the Beijing University of Chemical Technology have reviewed various models for predicting solubility of gases in ionic liquids (ILs), with a focus on CO2. The predictions of...
Xiong, Sandler, and Burnett (Chemical Engineering, University of Delaware) recently reported a new COSMO-SAC-2013 model, with parameters also available for the COSMO-RS implementation in ADF. With a single set of universal parameters, COSMO-SAC-2013 provides higher accuracy than previous...
DFT predictions by Jochen Autschbach helped to characterize a long sought-after dirhodium donor-acceptor carbene, an important reaction intermediate in various organic transformations. The NMR modules in ADF, by Jochen and others, was used to calculate the...
ADF calculations support a new mass spectrometric method to select the best catalysts from a combinatorial library in a combined experimental-theoretical study. The turnover frequency determining step for the Pd-catalyzed allylic alkylation is the nucleophilic...
Modeling the detailed chemical reaction dynamics of a complex system at the atomistic level is computationally too demanding for quantum-chemical methods and impossible with traditional force fields based on equilibrium properties. In the ReaxFF force...
