Twisted X-rays Help Explore Biological and Nanoscale Structures

The phenomenon of X-ray diffraction by crystals was discovered more than a century ago, and since then it has been a preferred technique for structure determination. It has established its presence in structural research in the fields of biology, and material science. However, many materials whose structures are unknown, do not easily crystallize as three-dimensional structures. [More]
