Published in 2017 at "Journal of Geophysical Research"

DOI: 10.1002/2016jc012400

Abstract: When phytoplankton growth is limited by low nutrient concentrations, full-depth-integrated phytoplankton biomass increases in response to intermittent mixing events that bring nutrient-rich waters into the sunlit surface layer. Here, it is shown how oscillatory winds… read more here.

Published in 2017 at "Journal of Geophysical Research"

DOI: 10.1002/2017jg003904

Abstract: Storm events can drive highly variable behaviour in catchment nutrient and water fluxes, yet short-term event dynamics are frequently missed by low resolution sampling regimes. In addition, nutrient source zone contributions can vary significantly within… read more here.

Published in 2020 at "Advanced Functional Materials"

DOI: 10.1002/adfm.201909501

Abstract: Although high carrier mobility organic field‐effect transistors (OFETs) are required for high‐speed device applications, improving the carrier mobility alone does not lead to high‐speed operation. Because the cut‐off frequency is determined predominantly by the total… read more here.
