Scientists develop high-performance Hg-based crystal for mid-far infrared birefringence

Mid- and far-infrared birefringent crystals are key functional materials for polarization control, laser technologies, and ...

Innovative optical atomic clock could combine single-ion accuracy with multi-ion stability

For many years, cesium atomic clocks have been reliably keeping time around the world. But the future belongs to even more accurate clocks: optical atomic clocks. In a few years' time, they could ...

Improved Resolution of X-Ray Diffraction Patterns of Protein Crystals at Low Temperature

POSSIBILITIES for X-ray crystal structure analysis of proteins are limited by the minimum spacings observed in diffraction. For many proteins, the minimum spacing is about 2.5 A.—a limit which does ...
