Edit galleryCharge ordering in BMIM-PF6 room temperature ionic liquid, as obtained from Molecular Dynamics simulations. Anions (red and orange) and cations (light and dark blue) are disposed in concentric shells. Correlations in the liquid persists up to several tens of angstroms and are responsible for the peculiar properties of this new class of materials. The VMD, Visual Molecular Dynamics, program was used to visualize and process the classical Molecular Dynamics trajectory. Rendering was performed using the Tachyon program.

Edit gallery Lithium-induced percolation networks form in room temperature ionic liquids, mostly due to the nature of the anions (that coordinate the lithium ions). These extended structures greatly affect transport properties and hinder conductivity [O. Andreussi and N. Marzari, 2014]

Edit galleryLithium-induced clustering in a room-temperature ionic liquid. While small, fairly spherical anions give rise to lithium-anion clusters. asymmetric anions lead to the formation of percolation networks, greatly decreasing lithium conductivity.

Marzari, J.Chem.Phys. 126, 064102 (2012)) correctly describes the electrostatic environment of the system and allows inexpensive modeling of realistic electrochemical environments.

Edit galleryHeat conduction in dielectric solids originates from the dynamics of atomic vibrations. The ridges represent the quantum vibrational energy levels of the perovskite CsPbBr3. Heat conduction originates from both vibrations’ particle-like propagation (blurred spheres) and wave-like tunnelling between different energy levels (blue waves).
