No need to strike while the iron is… small!
CNRS scientists have studied the evolution of the shape of gold nano-tetrapods and have revealed a two-stage kinetics: the four arms – initially pointed – quickly become blunt, before beginning …
Droplet levitation for self-assembly of liquid crystals
Researchers at the Laboratoire de Physique des Solides have studied the self-assembly of liquid-crystal particles inside a droplet when the latter evaporates within an acoustic levitator. The resulting structures formed …
Magneto-electric hysteresis effect in multiferroic GdMn2O5
Multiferroic compounds are widely studied for their magnetoelectric coupling, enabling polarization, for example, to be manipulated using a magnetic field. A new electronic state has just been discovered in the …
