A comparative study of single-particle cryo-EM with liquid-nitrogen and liquid-helium cooling

IUCrJ, 2019
Radiation damage is the most fundamental limitation for achieving high resolution in electron cryo-microscopy (cryo-EM) of biological samples. The effects of radiation damage are reduced by liquid-helium cooling, although the use of liquid helium is more

Accounting for electron-beam-induced warping of molecular nanocrystals in MicroED structure determination

IUCrJ
High-energy electrons induce sample damage and motion at the nanoscale to fundamentally limit the determination of molecular structures by electron diffraction.

Burst annealing of high temperature GaAs solar cells [PDF]

One of the major limitations of solar cells in space power systems is their vulnerability to radiation damage. One solution to this problem is to periodically heat the cells to anneal the radiation damage.

Using ACIS on the Chandra X-ray Observatory as a particle radiation monitor

, 2010
The Advanced CCD Imaging Spectrometer (ACIS) is one of two focal-plane instruments on the Chandra X-ray Observatory. During initial radiation-belt passes, the exposed ACIS suffered significant radiation damage from trapped soft protons scattering off the
