Twinning, which is a known problem in protein crystallography, usually hampers high-quality crystal structure determination unless it is detected and either avoided or corrected. Twinning is a crystal ...

TWINNING of crystals often results in the superposition of reciprocal lattice points and the appearance of a pseudo-lattice. In many cases this can be recognized from the diffraction data by the ...

This video shows the in situ compression of the 250 nm, <0001> oriented Ti-5at% Al single crystal pillar in TEM. Five consecutive tests have been performed. Ordinary dislocation plasticity and ...
