Wavelength and propagation direction (angle) are two fundamental properties of light. The ability to selectively control both a specific wavelength ...

Phase-contrast microscopy articles from across Nature Portfolio Phase contrast microscopy is a white-light optical microscopy technique that relies on sample-induced phase changes in illumination ...

Three-dimensional (3D) imaging is essential for investigating cellular structure and dynamics. Traditional optical methods ...

Intrinsic dispersion in periodic systems sets a fundamental bound for independent selectivity of resonant angles and ...

He does not consider the possibility of unintentional oblique illumination with phase contrast; it is this which has been studied in the present experiments.

Researchers developed a copper-based growth process that produces large-area trilayer graphene films with uniform thickness ...

Liquid-liquid phase separation (LLPS) has emerged as a major organizing principle in cells. Recent work showed that multiple components of integrin-mediated focal adhesions, including p130Cas can form ...

Digital holography is a very effective tool for three- dimensional imaging of objects, since it yields the phase information directly without the need for additional optics. Another advantage is that ...

Scanning transmission electron microscopy (STEM) has become an essential tool for investigating materials, providing detailed characterization at nano and atomic scales. By combining subangstrom ...

We present a variational reconstruction algorithm for the phase-retrieval problem by using the differential interference contrast microscopy. Principally, we rely on the transport-of-intensity ...

Phase contrast microscopy analysis showed foam sizes of 290–400 μm with thin film thicknesses of 6–9 μm. FEAS was tested with and without sodium persulfate (SPS) oxidant (oxidative foam) to treat ...
