In practical optical imaging systems, the lateral resolution is often defined by R=kλ/NA，where λ represents the illumination wavelength, NA denotes the numerical aperture of the imaging system, and k ...

U.N. Security Council Resolution 1701 was intended to create a buffer zone between Israel and Hezbollah. Here’s a look at why it didn’t and what lies ahead in efforts to end the conflict in Lebanon.

Coherent diffractive imaging (CDI) is a promising technique that leverages diffraction from a beam of light or electron for reconstructing the image of a specimen by eliminating the need for optics.

Abstract: Our research demonstrates the potential of a high-efficiency diffraction grating which consists of a semiellipsoid shape and hexagonal unit cell. Its parameters were calculated by using RCWA ...

Structural characterization is crucial to understanding protein function. Compared with X-ray diffraction methods, electron crystallography can be performed on nanometer-sized crystals and can provide ...
