Mørtsell, E. A.; Wenner, S.; Longo, P.; Andersen, S. J.; Marioara, C. D.; Holmestad, R.

The elemental distribution of a precipitate cross section, situated in a lean Al-Mg-Si-Cu-Ag-Ge alloy, has been investigated in detail by electron energy loss spectroscopy (EELS) and aberration corrected high angle annular dark field scanning transmission electron microscopy (HAADF-STEM).
Carbon nanofibers doped with nitrogen for the continuous catalytic ozonation of organic pollutants

Publication

Chemical Engineering Journal

Restivo, J.; Garcia-Bordejé, E.; Órfão, J. J. M.; Pereira, M. F. R.

Catalytic ozonation using carbon materials, in particular nanocarbons, has been appointed as an interesting alternative for the abatement of recalcitrant emerging organic pollutants. Efforts to achieve more efficient catalysts have been carried out, including carbon doping with heteroatoms.

The control of the phase distribution in multicomponent nanomaterials is critical to optimize their catalytic performance.
Alkoxide-intercalated NiFe-layered double hydroxides magnetic nanosheets as efficient water oxidation electrocatalysts

Publication

Inorganic Chemistry

Carrasco, J. A.; Romero, J.; Varela, M.; Hauke, F.; Abellán, G.; Hirsch, A.; Coronado, E.

Alkoxide-intercalated NiFe-layered double hydroxides were synthesized via the nonaqueous methanolic route. These nanoplatelets exhibit high crystalline quality as demonstrated by atomic resolution scanning transmission electron microscopy combined with electron energy-loss spectroscopy.
Role of C–N configurations in the photoluminescence of graphene quantum dots synthesized by a hydrothermal route

Publication

Scientific Reports

Permatasari, F. A.; Aimon, A. H.; Iskandar, F.; Ogi, T.; Okuyama, K.

Graphene quantum dots (GQDs) containing N atoms were successfully synthesized using a facile, inexpensive, and environmentally friendly hydrothermal reaction of urea and citric acid, and the effect of the GQDs’ C–N configurations on their photoluminescence (PL) properties were investigated.
Active phase distribution changes within a catalyst particle during Fischer–Tropsch synthesis as revealed by multi-scale microscopy

Publication

Catalysis Science & Technology

Cats, K. H.; Andrews, J. C.; Stéphan, O.; March, K.; Karunakaran, C.; Meirer, F.; de Groot, F. M. F.; Weckhuysen, B. M.

The Fischer–Tropsch synthesis (FTS) reaction is one of the most promising processes to convert alternative energy sources, such as natural gas, coal or biomass, into liquid fuels and other high-value products.
