Nanoprecipitates in single-crystal molybdenum-alloy nanopillars detected by TEM and atom probe tomography

Cécile Hébert, Helena Van Swygenhoven, Emad Oveisi, Barbora Bártová, Cécile Renée Maria Marichal

Transmission electron microscopy (TEM) supported by various chemical analyses techniques as well as atom probe tomography is applied to characterize newly identified nanosized precipitates in Mo-alloy nanopillars that were prepared by directional solidific ...

Annealing effects on the microstructure and photoluminescence of Eu3+-doped GdVO4 powders

Barbora Bártová

This work explores the influence of annealing temperature on microstructure and optical characteristics of Eu3+ doped GdVO4 (0.5, 1, 2 and 3 at.% Eu3+) nanopowders produced via co-precipitation synthesis. Samples were annealed at different temperatures (30 ...

Microstructure and precipitates in annealed Co38Ni33Al29 ferromagnetic shape memory alloy

Barbora Bártová

Transmission electron microscopy was performed to investigate the microstructure and precipitates in the annealed Co38Ni33Al29 ferromagnetic shape memory alloy. Apart from the dendritic secondary phase in the austenite matrix, micron-sized (up to 100 μm) f ...

Fabrication of polycrystalline (Y0.7Gd0.3)(2)O-3:Eu3+ ceramics: The influence of initial pressure and sintering temperature on its morphology and photoluminescence activity

Barbora Bártová

Nanocrystalline (Y0.7Gd0.3)(2)O-3 powder, synthetised via polymer complex solution method, was compacted into 25 pellets applying high pressures (173-867 MPa) for 30 s that were subsequently sintered at different temperatures (800-1400 degrees C) for 18 h. ...

Slip in directionally solidified Mo-alloy micropillars - Part I: Nominally dislocation-free pillars

Cécile Hébert, Helena Van Swygenhoven, Emad Oveisi, Barbora Bártová, Steven Van Petegem, Camelia Borca, Cécile Renée Maria Marichal

In situ Laue analysis during microcompression reveals plasticity in [0 0 1]-oriented, directionally solidified Mo alloy pillars to start with slip on the {1 1 2} < 1 1 1 > system having the highest Schmid factor followed by slip on the (1 1 0) plane contai ...

Electronic Interactions between "Pea" and "Pod": The Case of Oligothiophenes Encapsulated in Carbon Nanotubes

Cécile Hébert, Barbora Bártová

One of the most challenging strategies to achieve tunable nanophotonic devices is to build robust nanohybrids with variable emission in the visible spectral range, while keeping the merits of pristine single-walled carbon nanotubes (SWNTs). This goal is re ...

(Y0.5Lu0.5)2O3:Eu3+ nanopowders: Combustion synthesis, structure and optical properties

Barbora Bártová

In this work we explored the possibility of obtaining nanocrystalline (Y0.5Lu0.5)2O3 powders, doped with europium and co-doped with praseodium, employing polymer complex solution synthesis. Polyethylene glycol, with average molecular weight 200, served bot ...

Characterization of rare-earth doped Lu2O3 nanopowders prepared with polymer complex solution synthesis

Barbora Bártová

We explored a synthesis route based on the polymer complex solution method for the production of the rare-earth doped Lu2O3 crystalline nanopowders. In this type of synthesis polyethylene glycol is used both as fuel for the combustion reaction, and as nucl ...

Encapsulation of Conjugated Oligomers in Single-Walled Carbon Nanotubes: Towards Nanohybrids for Photonic Devices

Cécile Hébert, Barbora Bártová

Visible-light emitting single-walled carbon nanotubes (SWNTs)/organic hybrids have been successfully synthesized and promise to be a photon source to be used in future optoelectronic devices. The nanohybrids are "peapods" having sexithiophene molecules ins ...
