Super scintillators enable X-ray detection at an ultralow level

The introduction of lead-free metal halide powder into a scintillation screen took some tinkering. Once a KAUST team worked out the right technique, they were able to produce an exceptionally efficient, robust and flexible ...

Chlorophyll fluorescence illuminates plant function

Chlorophyll, the green pigment found in plants and algae, emits faint red and far-red light when illuminated during photosynthesis. This so called chlorophyll-a fluorescence conveys information about the instantaneous rate ...

Silicon core fishbone waveguide extends frequency comb

Frequency combs are becoming one of the great enabling technologies of the 21st century. High-precision atomic clocks, and high-precision spectroscopy are just two technologies that have benefited from the development of ...
