Researchers have incorporated an innovative ultra-broadband, quantum-entangled light source that generates a relatively wide range of infrared photons with wavelengths between 2 m and 5 m for dramatically downsizing the infrared spectroscopy system and upgrading its sensitivity. It can obtain spectra for various target samples, including hard solids, plastics, and organic solutions. This new technique …

Emerging research suggests it may be easier to use fusion as a power source if liquid lithium is applied to the internal walls of the device housing the plasma. Past experiments studied solid lithium coatings and found they could enhance a plasma. The researchers were pleased they could yield similar results with liquid lithium, as …
