Calcium Carbonate Polyamorphism and Its Role in Biomineralization: How Many Amorphous Calcium Carbonates Are There?
Julyan H. E. Cartwright, Antonio G. Checa, Julian D. Gale +2
Although the polymorphism of calcium carbonate is well known, and its polymorphs-calcite, aragonite, and vaterite-have been highly studied in the context of biomineralization, poly…
Electronic structure, imaging contrast and chemical reactivity of graphene moiré on metals
E. N. Voloshina, E. Fertitta, A. Garhofer +4
Realization of graphene moiré superstructures on the surface of 4d and 5d transition metals offers templates with periodically modulated electron density, which is responsible for…
Spin configurations in Co2FeAl0.4Si0.6 Heusler alloy thin film elements
C. A. F. Vaz, J. Rhensius, J. Heidler +11
We determine experimentally the spin structure of half-metallic Co2FeAl0.4Si0.6 Heusler alloy elements using magnetic microscopy. Following magnetic saturation, the dominant magnet…
Graphene on Rh(111): STM and AFM studies
E. N. Voloshina, Yu. S. Dedkov, S. Torbruegge +2
The electronic and crystallographic structure of the graphene/Rh(111) moiré lattice is studied via combination of density-functional theory calculations and scanning tunneling and…
Simulation of the shape memory effect in a NiTi nano model system
Daniel Mutter, Peter Nielaba
The shape memory behavior of a NiTi nanoparticle is analyzed by molecular dynamics simulations. After a detailed description of the equilibrium structures of the used model potenti…
