Reversible chemical delithiation/lithiation of LiFePO4: towards a redox flow lithium-ion battery

Michael Graetzel

Reversible chemical delithiation/lithiation of LiFePO4 was successfully demonstrated using ferrocene derivatives, based on which a novel energy storage system - the redox flow lithium-ion battery (RFLB), was devised by integrating the operation flexibility ...

Extracting energy from a flow: An asymptotic approach using vortex-induced vibrations and feedback control

François Gallaire, Philippe Meliga

This paper considers vortex-induced vibrations of a cylinder in water streams for renewable energy production. We use an analytical model recently obtained by the authors from the asymptotic analysis of a coupled flow-cylinder system, and assess the abilit ...

Nonthermal Melting of a Charge Density Wave in TiSe2

Paul Beaud

We use time-resolved optical reflectivity and x-ray diffraction with femtosecond resolution to study the dynamics of the structural order parameter of the charge density wave phase in TiSe2. We find that the energy density required to melt the charge densi ...
