Autoxidation chemistry: Bridging the gap between homogeneous radical chemistry and (heterogeneous) catalysis KU Leuven

Ive Hermans, Jozef Peeters, Pierre Jacobs
During the autoxidation of cyclohexane, abstraction of the alpha H-atom of the hydroperoxide product by chain-carrying peroxyl radicals produces both the desired alcohol and ketone products, as well as the majority of by-products. Rationalizing the impact of: this reaction, one should aim for a (catalytic) destruction of this hydroperoxide without the intervention of peroxyl chain-carriers. Starting from these new insights in the molecular ...

Developing and Implementing GAPc, a Gamification Project in Chemistry, toward a Remote Active Student-Centered Chemistry Course Bridging the Gap between Precollege and Undergraduate Education Hasselt University

Kristien BRASSINNE, Monique REYNDERS, Karin CONINX, Wanda GUEDENS
This paper describes the development and implementation of GAPc, a gamification project in chemistry. GAPc is an online active student-centered remedial teaching tool allowing prospective and enrolled students to electronically assess their knowledge of basic and advanced chemistry concepts via different game levels of expertise. This provides them with ways to correct potential shortcomings in view of academic education. A large number of ...

Relationship between river water chemistry and shell chemistry of two tropical African freshwater bivalve species KU Leuven

Zita Kelemen, Steven Bouillon
© 2018 Elsevier B.V. Both climate change and land-use changes represent serious environmental issues throughout Africa, and are expected to lead to significant changes in river hydrology and geochemistry. Freshwater bivalve shell geochemistry may provide useful information about past river characteristics (discharge, geochemistry) providing a baseline to help understand modern environmental changes. Shells of two species of freshwater mussels ...

Surface Chemistry and Characterization of Cellulose Nanocrystals: Chemistry, Analysis, and Applications KU Leuven

Samuel Eyley, Christina Schütz, Wim Thielemans
Summary Diverse methodologies are available for the characterization of cellulose nanocrystals (CNCs), but care must be taken in their application. The main techniques used for structural characterization include electron microscopy, scanning probe microscopy (AFM), scattering techniques such as dynamic light scattering (DLS), multi-angle light scattering (MALLS), small angle neutron scattering (SANS), and small angle X-ray scattering (SAXS), ...
