Atomic emission spectrometry (AES) remains at the forefront of analytical techniques for qualitative and quantitative elemental analysis across environmental, biological and industrial contexts. The ...

Yuri Ralchenko led one of the oldest teams at the National Institute for Standards and Technology. The fate of some ...

Researchers have discovered how to design and place single-photon sources at the atomic scale inside ultrathin 2D materials, ...

Quantum emitters work by releasing single photons, individual packets of light, on demand. This ability is critical because quantum technologies rely on absolute control over light and information.

Elemental spectroscopy is a method employed to examine in-service fluid samples such as engine oil or hydraulic fluid, to determine the presence and quantity of different substances. This approach ...

X-rays, a type of electromagnetic radiation with wavelengths from 0.01 to 10 nanometers, pack enough energy to pierce materials and interact with inner-shell electrons. 1 When they hit a sample, ...
