Mechanism of pressure induced amorphization of SnI4: a combined X-ray diffraction -- X-ray absorption spectroscopy study
Emiliano Fonda, Alain Polian, Toru Shinmei +2
We have studied the amorphization process of SnI4 up to 26.8GPa with unprecedented experimental details by combining Sn and I K edge X-ray absorption spectroscopy and powder X-ray…
Iodine molecule modifications with high pressure
Jingming Shi, Emiliano Fonda, Silvana Botti +8
Metallization and dissociation are key transformations in diatomic molecules at high densities particularly significant for modeling giant planets. Using X-ray absorption spectrosc…
Perovskite-type cobalt oxide at the multiferroic Co/Pb ZrTiO interface
K. Mohseni, A. Polyakov, H. B. Vasili +13
Magnetic Tunnel Junctions whose basic element consists of two ferromagnetic electrodes separated by an insulating non-magnetic barrier have become intensely studied and used in non…
Spectroscopies and electron microscopies unravel the origin of the first colour photographs
Victor de Seauve, Marie-Angélique Languille, Mathieu Kociak +7
The first colours photographs were created by a process introduced by Edmond Becquerel in 1848. The nature of these photochromatic images colours motivated a debate between scienti…
