Vegetable ash as raw material in the production of glasses and enamels, for example the contemporary vegetable ashes from Burgundy, France
Philippe Colomban, Aurélie Tournié, Frère Daniel De Montmollin +1
The powdery nature and high alkali content of vegetable ashes make them ideal raw materials to be used as modifiers of silicate compositions (glasses, enamels and ceramics). Their…
Raman spectra database of the glass beads excavated on mapungubwe hill and k2, two archaeological sites in South Africa
Aurélie Tournié, Linda C Prinsloo, Philippe Colomban
About two hundred coloured glass beads (red, yellow, green, blue, white, black, pink, plum) were selected among the thousands of beads excavated on Mapungubwe hill and at K2, archa…
Nanomechanics of single keratin fibres: A Raman study of the alpha helix -> beta sheet transition and water effect
Philippe Colomban, Raphaël Paquin
The use of micro-Raman spectroscopy, through chemical bond nano-scale probes, allows the changes in conformations (alpha helix -> beta sheet), chain orientation, disconnection of d…
Raman Spectroscopy of Nanostructures and Nanosized Materials
Philippe Colomban, Gwénael Gouadec
The interest of micro and tip-enhanced Raman spectroscopy to analyze nanosized and nanostructured materials, chiefly semiconductors, oxides and pristine or functionalized carbon na…
Polymerisation Degree and Raman Identification of Ancient Glasses used for Jewellery, Ceramics Enamels and Mosaics
Philippe Colomban
We demonstrate the utility of Raman spectroscopy as a technique for the identification of ancient glasses and enamel coatings of ceramics. As for any silicate glasses, the addition…
Phase diagram and Raman Imaging of Grain Growth Mechanisms in Highly Textured Pb(Mg1/3Nb2/3)O3-PbTiO3 Piezoelectric Ceramics
Mai Thi Pham, Gregory March, Philippe Colomban
Pb(Mg1/3Nb2/3)O3-PbTiO3 solid solution (PMN(1-x)-PTx) ceramics with 0 <x<1 have been prepared by homo-epitaxial templated grain growth (HTGG) using cubic PMN-PT single crystal seed…
