Ethanol dimers and water tetramers in zeolite ferrierite at high pressure

Movie of the first-principles molecular dynamics simulation of [Si-FER(4EtOH)(8H<sub>2</sub>O)]. This composite was obtained by pressure-induced intrusion of an ethanol-water solution in the all-silica zeolite ferrierite (Si-FER). <div><br><div>The cell parameters used in the simulation are those experimentally determined at pressure = 0.84 GPa with the diamond anvil cell and a 1:3 ethanol-water mixture as pressure transmitting medium.<div>Simulation temperature: room conditions (298 K)</div><div><br></div><div>Atom colors. Si-FER framework (in sticks) - Si: yellow; O: red. Guest molecules (in van-der-Waals representation) - Ethanol: C: gray; O: red; H: white.
