Crystal symmetry is a fundamental concept in materials science, playing a crucial role in determining structure-property relationships. Typically, a crystal is a solid composed of structural units ...

The spectral degeneracies emerging as a consequence of parity-time (PT) symmetry exhibit a profound divergence from their conventional counterparts. They possess non-Hermitian nature and are ...

(a) TEM image of the ultra-fine NiS nanorods with diameter of ~2.7 nm. (b) ADF-STEM image and (c) corresponding FFT pattern of the ultra-fine nanorod in radial direction. (d) ADF-STEM image and (e) ...

Scientists are championing a relatively new technique as a method to understand the structure of the early universe in three dimensions. With enough time and magnifying power, a telescope can gather ...
