Materials scientist describes new world order for glasses, liquids

85% Informative

Noncrystalline, amorphous atomic structure of liquids and glasses is chaotic.

Takeshi Egami studies these materials at the Department of Energy's Oak Ridge National Laboratory and the University of Tennessee , Knoxville .

Metallic glass presents itself as solid, but its disorganized atomic structure makes it technically a frozen liquid.

In 2017 , using synchrotron X-rays at the SPring-8 facility in Japan , Egami and his group found dynamic atomic correlation in water for the first time.

A 2022 paper by Egami and UTK 's Chae Woo Ryu described a density wave state, or ripple.

Evidence of this ripple had been observed before but was interpreted as noise in the experimental data caused by X-ray scattering.

In 2019 , Egami 's team used a novel experimental method of liquid levitation under vacuum that removed the noise and confirmed that the ripples are real.
