Photon counting of extreme ultraviolet high harmonics using a superconducting nanowire single-photon detector
aus: Applied Physics B
Laser-driven light sources in the extreme ultraviolet range (EUV) enable nanoscopic imaging with unique label-free elemental contrast. However, to fully exploit the unique properties of these new sources, novel detection schemes need to be developed. Here, we show in a proof-of-concept experiment that…

A viologen polymer and a compact ferrocene : Comparison of solution viscosities and their performance in a redox flow battery…
In this work, the synthesis and characterization of a compact, ferrocene tetramer and a linear viologen polymer is reported. The latter material is a new, 4,4′‐bipyridine containing, organo‐soluble polymer. As aimed for solubility in nonpolar solvents, a 2‐ethylhexyl‐moiety to promote organosolubility…

Recent advances in 2D heterostructures as advanced electrode materials for potassium-ion batteries
aus: Small structures
Owing to the cost-effectiveness, Earth abundance, and suitable redox potential, potassium-ion batteries (PIBs) stand out as one of the best candidates for large-scale energy storage systems. However, the large radius of K+ and the unsatisfied specific capacity are the main challenges for their commercial…

Recent evolution of flowering time across multiple European plant species correlates with changes in aridity - Greenhouse…
Ongoing global warming and increased drought frequencies have a large impact on plant populations and potentially drive evolutionary adaptations. Historical comparisons, where plants grown from seeds collected in the past (“ancestors”) are compared to plants grown from freshly collected seeds from the…
