Microscopes are an important tool in biomedical research as it allows for detailed observation and imaging of tissues. Since biological materials are opaque by their nature, severe light scattering ...

Advances in electron microscopy at Lehigh University are promising to shed light on the atoms of the nano-world that play a disproportionate role in the efficiency and safety of everyday materials.

Until recently, electron microscopy’s main engineering constraint has been spherical aberration of the objective lens - a feature of all round lenses that causes image distortion. Not only has ...
