| Open AccessPtychographic electron microscopy using high-angle dark-field scattering for sub-nanometre resolution imaging
Diffractive imaging can deliver wavelength-scale resolution with X-rays, although its use with electrons is hampered by experimental constraints. By applying ptychographic methods to transmission electron microscopy, Humphryet al. demonstrate sub-nanometre resolution using low-energy electrons.

Propagation stability of self-reconstructing Bessel beams enables contrast-enhanced imaging in thick media
Self-reconstructing laser beams can propagate deep into thick media, making them ideal for light-sheet microscopy of organic matter. By considering the rings of self-reconstructing Bessel beams, Fahrbach and Rohrbach present a technique for improving the contrast and resolution of this approach.
