To achieve light absorption and emission in the infrared, heavier elements that are lower on the periodic table must be used. Chemistry with those elements is more difficult, yielding more ...

These grills typically use gas to heat an infrared element, which then radiates intense, uniform heat up through the grill ...

Using the technique of spectroscopy [2], the team observed LMC68's near-infrared light, which allowed them to study the nova's ultra-hot phase during which many elements have been highly energized.
