Phase transition of BiNb1−xMnxO4−δ: Thermal analyse, NEXAFS, XPS and ESR-study

Reviews on Advanced Materials Science, 2019
The manganese-doped polymorphs of bismuth orthoniobate were studied using thermal analysis, ESR, XPS and NEXAFS spectroscopy. It was shown that the phase transition from the orthorhombic (α) to the triclinic (β) modification can be reversible and it can ...

Spin-Crossover Complexes in Direct Contact with Surfaces

Magnetochemistry, 2020
The transfer of the inherent bistability of spin crossover compounds to surfaces has attracted considerable interest in recent years. The deposition of the complexes on surfaces allows investigating them individually and to further understand the ...

The structure of the Au(111)/methylthiolate interface : new insights from near-edge X-ray absorption spectroscopy and X-ray standing waves [PDF]

, 2009
The local structure of the Au(111)([square root of]3×[square root of]3)R30°-methylthiolate surface phase has been investigated by S K-edge near-edge s-ray absorption fine structure (NEXAFS) both experimentally and theoretically and by experimental normal-

Interface structure and corrosion protection of hybrid particles prepared via surfactant- and silica-assisted wet ball milling

Results in Surfaces and Interfaces, 2022
The paper proposes a simple way to simultaneously modify iron particles with both silica and surfactant molecules, which involves wet ball milling of iron with silica glass and surfactants (stearic and n-perfluorononanoic acid).
