Unraveling surface structures of gallium promoted transition metal catalysts in CO2 hydrogenation

Nature Communications, 2023
Gallium-containing alloys have recently been reported to hydrogenate CO2 to methanol at ambient pressures. However, a full understanding of the Ga-promoted catalysts is still missing due to the lack of information about the surface structures formed ...

Comparative study of Co3O4(111), CoFe2O4(111), and Fe3O4(111) thin film electrocatalysts for the oxygen evolution reaction

Nature Communications, 2023
Water electrolysis to produce ‘green H2’ with renewable energy is a promising option for the upcoming green economy. However, the slow and complex oxygen evolution reaction at the anode limits the efficiency.

Are standing osmotic gradients the main driver of cerebrospinal fluid production? A computational analysis

Fluids and Barriers of the CNS, 2023
Background The mechanisms of cerebrospinal fluid (CSF) production by the ventricular choroid plexus (ChP) have not been fully deciphered. One prominent hypothesized mechanism is trans-epithelial water transport mediated by accumulation of solutes at the ...
