Web21 mei 2024 · Thermally-stable ionic liquids (ILs) have limited structural possibilities and lack coordinating anions or functional groups. Thermal stability effectively incurs a tunability penalty, limiting ionic liquid function to render them as simple heat-stable fluids. In this work, a series of new thermally-stable dicationic ionic liquids with pyridine functional groups, … Web23 mrt. 2024 · Simulating nuclear quantum dynamics in strongly anharmonic materials is an open challenge where state-of-the-art techniques fail. This is relevant in ferroelectrics, charge density waves, and crystals encapsulating light atoms, such as superconductive high-pressure hydrides. Here, the authors develop a theory to compute dynamical …

Metallic crystals consist of metal cations surrounded by a "sea" of mobile valence electrons. Covalent crystals are composed of atoms which are covalently bonded to one another. Molecular crystals are held together by weak intermolecular forces.
