We describe a phase plate for transmission electron microscopy taking advantage of a hitherto-unknown phenomenon, namely a beam-induced Volta potential on the surface of a continuous thin film. The ...

Quantitative phase imaging is a powerful, non-invasive and quantitative microscopy technique that allows multi-scale imaging of cellular systems, explain Mustafa Mir and Gabriel Popescu Imaging by ...

Researchers have developed an optical toolbox to build microscopes for a few hundred euros that deliver high-resolution images comparable to commercial microscopes that cost up to a thousand times ...
