Contrasting behavior of covalent and molecular carbon allotropes exposed to extreme ultraviolet and soft x-ray free-electron laser radiation
M. Toufarová, V. Hájková, J. Chalupský +17
All carbon materials, e.g., amorphous carbon (a-C) coatings and C60 fullerene thin films, play an important role in short-wavelength free-electron laser (FEL) research motivated by…
On the impact of capillarity for strength at the nanoscale
Nadiia Mameka, Jürgen Markmann, Jörg Weissmüller
The interior of nanoscale crystals experiences stress that compensates the capillary forces and that can be large, in the order of 1 GPa. Various studies have speculated on whether…
X-Ray Studies of Nanoporous Gold: Powder Diffraction by Large Crystals with Small Holes
Matthias Graf, Bao-Nam Dinh Ngô, Jörg Weissmüller +1
X-ray diffraction studies of nanoporous gold face the poorly understood diffraction scenario where large coherent crystals are riddled with nanoscale holes. Theoretical considerati…
In-situ Polarized Neutron Reflectometry: Epitaxial Thin Film Growth of Fe on Cu(001) by DC Magnetron Sputtering
Wolfgang Kreuzpaintner, Birgit Wiedemann, Jochen Stahn +11
The step-wise growth of epitaxial Fe on Cu(001)/Si(001), investigated by in-situ polarized neutron reflectometry is presented. A sputter deposition system was integrated into the n…
SANS contrast variation study of magnetoferritin structure at various iron loading
Lucia Melnikova, Viktor I. Petrenko, Mikhail V. Avdeev +6
Magnetoferritin, a synthetic derivate of iron storage protein - ferritin, has been synthesized with different iron oxide loading values. Small-angle neutron scattering experiments…
