Scientific Innovation Technological Application Material Physics

Researchers from the University of Trento and other European institutions have discovered that fundamental atomic vibrations in ultra-stable glasses remain similar to those in ordinary glasses. This finding, published in Physical Review X, challenges previous computer simulations and may have applications in improving OLED electronics and pharmaceutical drug delivery.
