Raj group bids farewell to Ana Gabriela!

Bola and Viviana are selected as paticipants of 3rd US School on Total Scattering Analysis at Oak Ridge National Laboratory! This school is aimed at introducing total scattering data and modelling methods and demonstrating their use in understanding complex functional materials, in addition to reviewing recent developments and future directions...

Abstract We report the transformation of an amorphous mixture of Li 0.5 La 0.5 TiO 3 (LLTO) directly into a single phase dense polycrystal, all within a few seconds at about 800°C by the flash method. The starting material is a chemically-prepared precursor powder that experiences concurrent crystallization and densification...

Raj lab wishes happy birthday to Seohyeon!

Congratulations Viviana and Bola!

We bid farewell to Rubens, best wishes on your new journey!

Abstract We report in-situ measurements of impedance spectroscopy during flash experiments with single crystals of cubic-yttria stabilized zirconia, conducted in ambient air at 300 °C to 700 °C under a direct current electric field. Platinum electrodes transition from blocking to non-blocking behavior before the onset of flash, indicating a transition to partial...

Abstract Flash sintering experiments of ceramics indicate the formation of a state far from equilibrium. It is hypothesized that this state is enriched by Frenkel defects. The possibility is investigated that such lattice defects are being generated by a proliferation of lattice vibrations that lie close to the Brillouin zone...
