Although several past studies have investigated the formation of crystals from identical particles, the conditions under which non-uniform particles crystallize and the crystals resulting from this process are still poorly ...
A team of physicists at Université Paris-Saclay has, for the first time, observed spontaneous quasi-crystal self-assembly. The observation occurred during an experiment they were conducting with tiny vibrating magnetic spheres. ...
Slanted exterior edges on tiny magnetic disks could lead to a breakthrough in data processing. Materials researchers of the Helmholtz-Zentrum Dresden-Rossendorf, Germany, were able to create magnetic vortices with a diameter ...
