Materials called relaxor ferroelectrics have been used for decades in technologies like ultrasounds, microphones, and sonar ...

Accelerator-based high-energy electron diffraction determines 3D atomic structure of materials New method using ultrashort ...

Researchers with the Department of Energy's Oak Ridge National Laboratory and the University of Tennessee, Knoxville, have created an innovative method to visualize and analyze atomic structures ...

Crystallography is the science of analyzing the pattern produced by shining an X-ray beam through a material sample. A powder sample produces a different pattern than solid crystal. One longstanding ...

The intermediate range order of covalent glasses has been extensively studied in terms of the first sharp diffraction peak (FSDP), but the direct observation of the atomic density fluctuations that ...

Since their discovery in 1982, exotic materials known as quasicrystals have bedeviled physicists and chemists. Their atoms arrange themselves into chains of pentagons, decagons and other shapes to ...

MIT-led researchers have, for the first time, directly mapped the 3D atomic and polar structure of relaxor ferroelectrics, materials critical to sensors and energy devices. Using multi-slice electron ...

Recent research led by the University of Trento reveals that fundamental atomic vibrations remain unchanged also in ...
