Secondary Phase CeO2 Precipitates in Ce,Er-Doped Na0.5La0.5MoO4 Single Crystals Grown by Czochralski Method
Philippe Buffat, Elena Suvorova Buffat
Analytical scanning and transmission electron microscopy were used to study the microstructure of Ce,Er-doped Na0.5La0.5MoO4 laser crystals. Crystals were grown by the Czochralski method from the melts with a nominal composition of Na0.5La0.5−xCexEr0.005Mo ...
2023Structure, Oxygen Content and Electric Properties of Titanium Nitride Electrodes in TiNx/La:HfO2/TiNx Stacks Grown by PEALD on SiO2/Si
Philippe Buffat, Elena Suvorova Buffat
This work reports experimental results of the quantitative determination of oxygen and band gap measurement in the TiNx electrodes in planar TiNx top/La:HfO2/TiNx bottom MIM stacks obtained by plasma enhanced atomic layer deposition on SiO2. Methodological ...

Philippe Buffat, Elena Suvorova Buffat
High-resolution transmission electron microscopy, electron diffraction, and electron energy-loss spectroscopy provide information on the structural evolution, dielectric function, and bandgap values of nanocrystalline 10nm thick lanthanum doped hafnia (La: ...
AMER INST PHYSICS2020Energy dependent structure of Xe ion tracks in YBCO and the effect on the superconductive properties in magnetic fields
Philippe Buffat, Elena Suvorova Buffat
The morphology and structure of damaged regions (tracks) produced by swift heavy 167, 77, and 46 MeV 132Xe23+ ions in YBCO-based second generation industrial high temperature superconductors wires (2G HTS) were studied using transmission electron microscop ...
2019Effects of Kr and Xe ion irradiation on the structure of Y2O3 nanoprecipitates in YBCO thin film conductors
Philippe Buffat, Elena Suvorova Buffat
The response of Y2O3 nanoprecipitates in a 1-mu m YBa2Cu3O7-x layer from a superconducting wire Ag/YBCO/buffer metal oxides/Hastelloy to 107 MeV Kr and 167 MeV Xe ion irradiation was investigated using a combination of transmission electron microscopy, dif ...
2018Chromate Resistance Mechanisms in Leucobacter chromiiresistens
Rizlan Bernier-Latmani, Elena Suvorova Buffat
Chromate is one of the major anthropogenic contaminants on Earth. Leucobacter chromiiresistens is a highly chromate-resistant strain, tolerating chromate concentrations in LB medium of up to 400 mM. In response to chromate stress, L. chromiiresistens forms ...

Philippe Buffat, Elena Suvorova Buffat
Dispersed Ag nanoparticles were prepared in aqueous solutions in the presence of pure poly[2-(dimethylamino)ethyl methacrylate] (poly-DMAEMA), poly[2-deoxy-2-methacrylamido-d-glucose] (poly-MAG), and their copolymers of poly[MAG–DMAEMA] with different mole ...
Springer Verlag2015Long-term in-situ oxidation of biogenic uraninite in an alluvial aquifer: impact of dissolved oxygen and calcium
Rizlan Bernier-Latmani, Elena Suvorova Buffat, Harish Veeramani, Daniel Scott Alessi
Oxidative dissolution controls uranium release to (sub)oxic pore waters from biogenic uraninite produced by natural or engineered processes, such as bioremediation Laboratory studies show that uraninite dissolution is profoundly influenced by dissolved oxy ...
Amer Chemical Soc2015Combined scanning transmission X-ray and electron microscopy for the characterization of bacterial endospores
Rizlan Bernier-Latmani, Elena Suvorova Buffat, Paul Pao-Yun Shao, Imrich Barak, Jan Jamroskovic
Endospores (also referred to as bacterial spores) are bacterial structures formed by several bacterial species of the phylum Firmicutes. Spores form as a response to environmental stress. These structures exhibit remarkable resistance to harsh environmenta ...
