THE DESIRE TO DETECT ever fewer photons and ions, including some at great distances from Earth, pushes the frontiers of analytical capability. A symposium at Pittcon in Chicago earlier this month ...

First things first. What is FTIR imaging? In an FTIR image (often called chemical image), each pixel is composed of an entire IR spectrum. These images allow a very detailed and spatially resolved ...

The detector array consists of plastic scintillator detectors, quadrant silicon detectors (QSD), double-sided silicon detectors (DSSD) and high-purity germanium (HPGe) detectors. Exotic nuclei near ...

a, Example of ISM-FLUX on nanorulers consisting of three fluorophores with 40 nm spacing between nearest neighbours. With a single-element detector, none of the nanorulers can be resolved, due to the ...

WASHINGTON — NASA is investigating a detector problem common to three primary instruments on the James Webb Space Telescope (JWST) that could get worse with time as a planned 2014 launch date for the ...
