Worldwide version-controlled database of glacier thickness observations

Welty, Ethan ; Zemp, Michael ; Navarro, Francisco ; Huss, Matthias ; Fürst, Johannes J. ; Gärtner-Roer, Isabelle ; Landmann, Johannes ; Machguth, Horst ; Naegeli, Kathrin ; Andreassen, Liss M. ; Farinotti, Daniel ; Li, Huilin ; GlaThiDa Contributors

In: Earth System Science Data, 2020, vol. 12, no. 4, p. 3039–3055

Although worldwide inventories of glacier area have been coordinated internationally for several decades, a similar effort for glacier ice thicknesses was only initiated in 2013. Here, we present the third version of the Glacier Thickness Database (GlaThiDa v3), which includes 3 854 279 thickness measurements distributed over roughly 3000 glaciers worldwide. Overall, 14 % of global...

Plasmon-assisted Förster resonance energy transfer at the single-molecule level in the moderate quenching regime

Bohlen, J. ; Cuartero-González, Á. ; Pibiri, E. ; Ruhlandt, D. ; Fernández-Domínguez, A. I. ; Tinnefeld, P. ; Acuna, Guillermo P.

In: Nanoscale, 2019, vol. 11, no. 16, p. 7674–7681

Metallic nanoparticles were shown to affect Förster energy transfer between fluorophore pairs. However, to date, the net plasmonic effect on FRET is still under dispute, with experiments showing efficiency enhancement and reduction. This controversy is due to the challenges involved in the precise positioning of FRET pairs in the near field of a metallic nanostructure, as well as in the...
