Oxidation Induced Doping of Nanoparticles Revealed by in Situ X-ray Absorption Studies
(American Chemical Society, 2016-05)
Doping is a well-known approach to modulate the electronic and optical properties of nanoparticles (NPs). However, doping at nanoscale is still very challenging, and the reasons for that are not well understood. We studied ...
The role of solvent on the doping of polyaniline with Fe(III) ions
(ELSEVIER SCIENCE SA, 2010)
The products formed from the reaction of emeraldine base polyaniline (EB-PANI) with Fe(III) ions in N-methyl-pyrrolidone (NMP), dimethylacetamide (DMA), dimethylformamide (DMF) and m-cresol media have been investigated ...
X-ray-induced conductivity in iron-doped lithium niobate crystals
(2003-07-01)
Illumination of photorefractive, iron-doped lithium niobate crystals (LiNbO 3:Fe) with x-rays generates a conductivity that we determine from the speed of hologram erasure. The doping levels of the crystals and the ...

Illumination of photorefractive, iron-doped lithium niobate crystals (LiNbO 3:Fe) with x-rays generates a conductivity that we determine from the speed of hologram erasure. The doping levels of the crystals and the ...
Effect of chromium on magnetite formation
(1995)
Chromium-doped magnetite is the traditional catalyst used in the high temperature shift reaction in industrial processes. This work reports a method for preparing this solid, by heating chromium-doped iron(III)hydroxoacetates ...
Mössbauer and vibrational DOS studies of diluted magnetic tin oxides and nano iron oxides
(Springer, 2013-04)
The magnetic properties and Mössbauer results for SnO2 doped with 57Fe are reviewed, and the values of isomer shift and quadrupole splitting are compared with the results obtained by ab initio calculations. It is concluded ...
