This incredibly detailed image of an ant obtained at the ESRF’s ID19 beamline is based on a technique called X-ray grating interferometry, which provides high-sensitivity differential phase and dark-field (small angle X-ray scattering) signals. It therefore bears tremendous potential for imaging tiny density differences and structures at the nanoscale that produce low absorption contrast.
There is nothing so practical as a good theory.
20 years of battery life! The NanoTritium betavoltaic power source from City Labs is a thumb-sized battery that draws on the energy released from its radioactive element to provide continuous nanoWatt power for over 20 years.
