A new technology platform to study high-speed impacts on a tabletop has been developed at the University of Illinois. This method uses a laser to launch thin metal foils at km/s velocities. Although “laser-launched flyer plates” have been studied for more than 30 years, they have not been broadly utilized in shock compression science...

Ferroelectric materials (switchable spontaneous electric polarization under an external electric-field) are also piezoelectric (convert mechanical energy into electric energy) and pyroelectric (convert a temperature change into electric energy). The combined properties of memory, piezoelectricity, and pyroelectricity, make ferroelectric...

A new class of high Tc superconductors having a dense carbon framework structures is predicted using first-principles calculations. The current search for high-temperature superconductivity is now focused on materials containing low-Z elements due to the large phonon contribution necessary for BCS-type behavior. An additional strategy...
