JEE Advanced 2026 Syllabus: The Indian Institute of Technology (IIT) Roorkee, the conducting authority for JEE Advanced 2026, has published the detailed, topic-wise syllabus on its official website at ...

Abstract: In the currently deployed scheme utilizing Acousto-Optic Tunable Filter (AOTF) in conjunction with the echelle grating, the maximum spectral overlap for low diffraction orders exceeds 2/3, ...

This series of papers deals with the description and visualization of mathematical functions used to describe a powder pattern. Accompanying each part is a collection of user-friendly, interactive and ...

I love this question from Youtuber Marques Brownlee, who goes by MKBHD. He asks: "What is a photo?" It's a deep question. Just think about how early black-and-white film cameras worked. You pointed ...

We present a single-shot dual-wavelength common-path off-axis digital holographic microscopic (CO-DHM) imaging method based on two-dimensional grating diffraction. This method improves the utilization ...

Terahertz waves are finding important applications in diverse fields, and meanwhile the manipulation of terahertz waves calls for the development of various functional devices. Here, we have designed ...

Article subjects are automatically applied from the ACS Subject Taxonomy and describe the scientific concepts and themes of the article. Powder X-ray diffraction (XRD) is a common characterization ...

Silica is one of the most abundant minerals in Earth’s crust and since the dawn of civilization its use has accompanied mankind’s technological evolution. Understanding crystallization is crucial in ...

The packing of cellulose nanocrystals (CNC) in the anisotropic chiral nematic phase has been investigated over a wide concentration range by small-angle X-ray scattering (SAXS) and laser diffraction.

We demonstrate single-molecule fluorescence imaging beyond the optical diffraction limit in 3 dimensions with a wide-field microscope that exhibits a double-helix point spread function (DH-PSF). The ...
