Characterization of dislocations in protein crystals using synchrotron white-beam topography

Primary radiation damage of protein crystals by an intense synchrotron X-ray beam.

X-ray radiation damage of a lysozyme single crystal by an intense monochromatic beam from a third-generation radiation source at the Advanced Photon Source has been studied. The results show that primary radiation damage is linearly dependent on the X-ray dose even when the crystal is at cryogenic temperatures. The existence of an upper limit for the primary radiation damage was observed. Above...

Dislocations in Sodium-Chloride Crystals

Distributions of dislocations in sodium chloride crystals, which were induced by heat treatment or working, were investigated, using a newly developed etchant. The crystals, which were annealed above 3 0 0 ° C , showed reduced dislocation densities and rearranged dislocation patterns. By raising the temperature to 600 ° C or 700 ° C many elongated subboundaries or subboundaries arranged in the ...

The Role of Geometrically Necessary Dislocations in Cantilever Beam Bending Experiments of Single Crystals

The mechanical behavior of single crystalline, micro-sized copper is investigated in the context of cantilever beam bending experiments. Particular focus is on the role of geometrically necessary dislocations (GNDs) during bending-dominated load conditions and their impact on the characteristic bending size effect. Three different sample sizes are considered in this work with main variation in ...
