Characterization of commercial synthetic resins by pyrolysis-gas chromatography/mass spectrometry : application to modern art and conservation
American Chemical Society (2009-04-15)To characterize a set of synthetic resins, a methodology by pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS) has been developed. The studied reference materials were commercial versions of a wide range of synthetic ... -
Enhanced conductivity and nonlinear voltage–current characteristics of nonstoichiometric BaTiO3 ceramics
Wiley-Blackwell (2011-03-21)The electrical conductivity of both BaO-deficient and TiO2-deficient BaTiO3 ceramics shows nonohmic, low-field characteristics at temperatures >∼200°C in contrast to stoichiometric BaTiO3 for which the electrical conductivity ... -
Spectral analysis of femtosecond pulse diffraction through binary diffractive optical elements: theory and experiment
Optical Society of America (2008)We report on the changes in the spectrum of a femtosecond pulse originated by diffraction of the ultrashort waveform through a circularly symmetric binary diffractive optical element. The analysis is performed in the ...
