Cobalt Carbide Identified as Catalytic Site for the Dehydrogenation of Ethanol to Acetaldehyde
Two cobalt catalysts, Co/SBA-15 and Co/SiO2, have been studied in steam reforming of ethanol (SRE). Besides the steam reforming products, ethoxide dehydrogenation to acetaldehyde is observed as one of the main reactions. Although by hydrogen treatment cobalt is...
NADPH thioredoxin reductase C and thioredoxins act concertedly in seedling development
Thiol-dependent redox regulation of enzyme activity plays a central role in the rapid acclimation of chloroplast metabolism to ever fluctuating light availability. This regulatory mechanism relies on ferredoxin (Fdx) reduced by the photosynthetic electron transport...
Photonic Tuning of the Emission Color of Nanophosphor Films Processed at High Temperature
Photonics offers new possibilities to tailor the photoluminescence process in phosphor-converted light emitting diodes. Herein, it is demonstrated that the emission color of thin layers of rare-earth doped nanocrystals can be strongly modulated in tunable spectral...
Design and Realization of a Novel Optically Disordered Material: A Demonstration of a Mie Glass
Herein, a diffusive material presenting optical disorder isintroduced, which represents an example of a Mie glass. Comprising spherical crystalline TiO2 nanoparticles randomlydispersed in a mesoporous TiO2 matrix, it is proved that thescattering of light in this...
Electron injection and scaffold effects in perovskite solar cells
In spite of the impressive efficiencies reported for perovskite solar cells (PSCs), key aspects of their working principles, such as electron injection at the contacts or the suitability of the utilization of a specific scaffold layer, are not yet fully understood....
