Holistic approach for studying planetary hydrospheres: Gibbs representation of ices thermodynamics, elasticity and the water phase diagram to 2300 MPa
Journaux, Baptiste; Brown, Michael; Pakhomova, Anna; Collings, Ines; Petitgirard, Silvain; Espinoza, Penny; Ott, Jason; Cova, Federico Hector; Garbarino, Gaston; Hanfland, Michael (Peer reviewed; Journal article, 2020)Gibbs energy representations for ices II, III, V, and VI are reported. These were constructed using new measurements of volumes at high pressure over a range of low temperatures combined with calculated vibrational energies ... -
Insights on microstructural evolution and capacity fade on diatom SiO <inf>2</inf> anodes for lithium-ion batteries
Hua, Weicheng; Nylund, Inger-Emma; Cova, Federico Hector; Svensson, Ann Mari; Blanco, Maria Valeria (Peer reviewed; Journal article, 2023)is a promising material for developing high-capacity anodes for lithium-ion batteries (LIBs). However, microstructural changes of anodes at the particle and electrode level upon prolonged cycling remains unclear. In this ... -
Phase stability and electronic structure of iridium metal at the megabar range.
Monteseguro, Virginia; Sanz, Juan Angel; Cuartero, Vero; Cova, Federico Hector; Abrikosov, Igor; Olovsson, Weine; Popescu, Catelin; Pascarelli, Sakura; Garbarino, Gaston; Jonsson, Johan; Irifune, Tetsuo; Errandonea, Daniel (Journal article; Peer reviewed, 2019)The 5d transition metals have attracted specific interest for high-pressure studies due to their extraordinary stability and intriguing electronic properties. In particular, iridium metal has been proposed to exhibit a ... -
Transportable double-sided laser heating setup with variable configuration for in-situ synchrotron X-Ray diffraction, X-ray Transmission Microscopy and multimegabar pressure DACs experiments
Fedotenko, Timofey; Dubrovinsky, Leonid S.; Aprilis, Giorgios; Koemets, Egor; Snigirev, Anatoly; Barannikov, Aleksandr; Ershov, Piotr; Cova, Federico Hector; Hanfland, Michael; Dubrovinskaia, Natalia (Journal article; Peer reviewed, 2019)The diamond anvil cell (DAC) technique combined with laser heating is one of the major methods for studying materials at high pressure and high temperature conditions. In this work, we present a transferable double-sided ...
