Kombinierte lösungs‐ und oberflächengestützte Synthese eines vollständig kondensierten, kreuzförmigen Phthalocyanin‐Pentamers

open access: yesAngewandte Chemie, EarlyView.
Ein Phthalocyanin‐(Pc)‐Pentamer wurde durch die Kombination lösung‐ und oberflächengestützter Synthese unter Ultrahochvakuumbedingungen erhalten. Die entstandene Pc‐basierte Nanostruktur weist ein exaktes stöchiometrisches Verhältnis von 4:1 zweier unterschiedlicher Metallionen auf, mit präziser Positionskontrolle.

Development of an Analytic Nodal Diffusion Solver in Multigroups for 3D Reactor Cores with Rectangular or Hexagonal Assemblies. [PDF]

open access: yes, 2009
More accurate modelling of physical phenomena involved in present and future nuclear reactors requires a multi-scale and multi-physics approach. This challenge can be accomplished by the coupling of best-estimate core-physics, thermal-hydraulics and ...

Streamflow variations across the Andes (18°–55°S) during the instrumental era

open access: yesScientific Reports, 2019
The rivers originating in the southern Andes (18°–55°S) support numerous ecosystems and a large number of human populations and socio-economic activities in the adjacent lowlands of Chile, Argentina and Bolivia. Here we show that ca.

Hochdrucksynthese von Antimonnitrid Sb3N5 und Polynitrid Sb2N8 mit einfach gebundenen N810− Ketten

open access: yesAngewandte Chemie, EarlyView.
Hochdrucksynthesen zwischen Antimon und molekularem Stickstoff in einer laserbeheizten Diamantstempelzelle führten zur Bildung von oC32‐Sb3N5 (51(1) GPa) und mP20‐Sb2(N8) (> 100 GPa). Beide Phasen wurden mittels Einkristall‐Röntgenmikrodiffraktion identifiziert und durch Berechnungen mittels Dichtefunktionaltheorie vollständig bestätigt.

Evidence of Quaternary tectonics along Río Grande valley, southern Malargüe fold and thrust belt, Mendoza, Argentina [PDF]

open access: yes, 2019
The Malargüe fold and thrust belt is developed in the Argentinian Andes between 34° and 37° S, through the tectonic inversion of Upper Triassic and Lower Jurassic depocenters of the Neuquén Basin, with an uplift history since the Cretaceous.
