Wykład zatytułowany Metal iodates under high-pressure wygłosi prof. Daniel Errandonea (Departamento de Física Aplicada─ICMUV, MALTA Consolider Team, Universitat de Valencia, Hiszpania).
The goal of this talk is to report a systematic and balanced review of the progress made in recent years on the high-pressure behavior of iodates, a group of materials with multiple technological applications and peculiar behaviors under external compression. This talk will include results obtained from multiple characterization techniques which include X-ray diffraction, Raman and infrared spectroscopy, optical-absorption and resistivity. The discussion of the results from experiments will be combined with density-functional theory calculations which have been shown to be a very useful tool for the interpretation of experimental data. Throughout the presentation many of the phenomena observed will be connected to the presence of a lone electron pairs of the iodine atoms in the studied iodates. The presence of the lone electron pairs plays a crucial role in the high-pressure behavior of iodates and it is associated with many of the phenomena to be discussed, in particular with the pressure-induced changes in the character of iodine-oxygen bonds, which causes many physical properties to behave nonlinearly.
