Abstract: The possibility of a series expansion for the diffracted fields by a dielectric sphere or circular cylinder is considered by first expanding the Mie scattering coefficients into a geometric ...
A new NASA mission to map the solar wind has returned some of its first images from its position in low Earth orbit. The Polarimeter to Unify the Corona and Heliosphere ( PUNCH) mission launched on 11 ...
Wavefront aberrations introduce speckles in the telescope science images, which are patterns of diffracted starlight that can mimic the appearance of planets, complicating the detection of faint ...
This is a critical review of artificial intelligence/machine learning (AI/ML) methods applied to battery research. It aims at providing a comprehensive, authoritative, and critical, yet easily ...
The carbon atoms scatter the X-ray light—similar to the way light is diffracted by a grating. The diffraction pattern allows inferences to be drawn about the current arrangement of the atoms in ...
During commissioning, PUNCH’s NFI instrument captured this image of the new Moon as it passed by the Sun in the sky on April 27, 2025. The new Moon appears full, because it is illuminated by ...
The authors provide important insights into a system of insect camouflage where a coating of self-made nanoparticles (brochosomes) reduces the reflection of UV light, leading to lower predation by ...

Supramolecular chemistry is the study of entities of greater complexity than individual molecules — assemblies of molecules that bond and organize through intermolecular interactions. The design ...
Researchers used laser compression to study liquid carbon for the first time, enabling insights into extreme states relevant ...
Purified proteins are crystallized, and an x-ray beam is applied to the crystals. The rays are diffracted by the electron clouds of the atoms present in the crystal. The crystals are gradually ...
