Highly Dynamic Cellular-Level Response of Symbiotic Coral to a Sudden Increase in Environmental Nitrogen

Anders Meibom, Duncan Thomas Lindsay Alexander, Isabelle Domart-Coulon, Christophe Kopp

Metabolic interactions with endosymbiotic photosynthetic dinoflagellate Symbiodinium spp. are fundamental to reef-building corals (Scleractinia) thriving in nutrient-poor tropical seas. Yet, detailed understanding at the single-cell level of nutrient assim ...

Hypolimnetic Oxygen Depletion in Eutrophic Lakes

Alfred Johny Wüest, Beat Mueller

The oxygen-consuming processes in the hypolimnia of freshwater lakes leading to deep-water anoxia are still not well understood, thereby constraining suitable management concepts. This study presents data obtained from 11 eutrophic lakes and suggests a mod ...

A Review of RedOx Cycling of Solid Oxide Fuel Cells Anode

Jan Van Herle, Aïcha Hessler-Wyser, Antonin Faes

Solid oxide fuel cells are able to convert fuels, including hydrocarbons, to electricity with an unbeatable efficiency even for small systems. One of the main limitations for long-term utilization is the reduction-oxidation cycling (RedOx cycles) of the ni ...

Artificial Photosynthesis at Soft Interfaces

Hubert Girault, Fernando Cortes Salazar, Manuel Alejandro Méndez Agudelo, Astrid Johana Olaya Avendano, Peiyu Ge, Imren Hatay, Haiqiang Deng, Patrick Voyame

The concept of artificial photosynthesis at a polarised liquid membrane is presented. It includes two photosystems, one at each interface for the hydrogen and oxygen evolution respectively. Both reactions involve proton coupled electron transfer reactions, ...

RedOx Stability of Anode Supported Solid Oxide Fuel Cells

Antonin Faes

The weakness of nickel-based solid oxide fuel cell anodes is their low ability to withstand re-oxidation at working temperature, especially for the anode-supported cell design. The volume expansion coming along with nickel (Ni) oxidation induces stresses i ...

Curvature and Strength of Ni-YSZ Solid Oxide Half-cells after RedOx Treatments

Antonin Faes, Darlene Goldstein

One of the main drawbacks of anode-supported solid oxide fuel cell technology is the limited capability to withstand reduction and oxidation (“RedOx”) of the Ni phase. This study compares the effect of RedOx cycles on curvature and strength of half-cells, ...
