Uneven strain distribution induces detwinning in penta-twinned nanoparticles

Twinned nanoparticles have regions of clear symmetry that share the same crystal lattice, separated by a clear boundary. Changing the twin structure can affect the properties of the nanoparticles, which makes controlling ...

High-speed atomic force microscopy helps explain role played by certain biomolecules in DNA wrapping dynamics

In plants and animals, the basic packaging units of DNA, which carry genetic information, are the so-called nucleosomes. A nucleosome consists of a segment of DNA wound around eight proteins known as histones.
