Nearly 100 years ago, a seemingly simple discovery revolutionized the microscope. The introduction of phase contrast, which ...

Fifteen years ago, physicists worked out a method to increase image contrast by hitting the electron imaging beam with an ...

Nanoscale electromagnetic fields formed at localized structures such as interfaces play a pivotal role in the properties of state-of-the-art electronic and spintronic devices. Direct characterization ...

A new purpose-built microscope has been developed that uses the complex properties of UV light to improve image resolution and contrast. Most cells are transparent at visible wavelengths, which means ...
