Scanning and transmission electron microscopy for evaluation of order/disorder in bone structure

Philippe Buffat, Elena Suvorova Buffat

A comparative characterization of the structure of normal and abnormal (osteoporotic) human lumbar and thoracic vertebrae samples was carried out to reveal the type of possible disorder. Samples from the bone fragments extracted during the surgery due to v ...

Electron microscopy of biomaterials based on hydroxyapatite

Philippe Buffat, Elena Suvorova Buffat

Three types of biomaterials based on hydroxyapatite are synthesized and investigated. Hydroxyapatite nanocrystals or microcrystals precipitated from low-temperature aqueous solutions serve as the initial material used for preparing spherical porous granule ...

Pathological mineralization of cardiac valves: Causes and mechanism

Philippe Buffat, Elena Suvorova Buffat

Objective. Mechanism of calcification of cardiac valves was investigated through a comparative characterization of structure, morphology, and size of hydroxyapatite (HAP) crystals formed in mineral deposit on cardiac valves, bone tissue, and crystals synth ...

Characterization of perovskite powders for cathode and oxygen membranes made by different synthesis routes

Philippe Buffat, Nicolas Xanthopoulos, Jan Van Herle, Elena Suvorova Buffat, Sébastien Vaucher

Strontium lanthanum manganite (LSM) and lanthanum ferrite (LSF) perovskite cathode and oxygen membrane materials were synthesized using different techniques: spray pyrolysis, a modified citrate route, oxalate and carbonate co-precipitations. The use of Ca, ...

Stability of Ag nanoparticles dispersed in amphiphilic organic matrix

Philippe Buffat, Elena Suvorova Buffat

Nano- and thin-film technologies based on novel systems associating metals particles to polymer matrix open a broad range of different applications. Such composites were found to be more efficient and safe, for instance, in biomedical needs. The Ag/poly(N- ...
