IN usual experiments with diffraction of X-rays by crystals, an effect of space-lattice is always observed owing to the penetration of the rays into the depth of the crystal. The thin layers, however, ...

With the 2019 Nobel Prize for Physics due to be announced on Tuesday 8 October, Physics World journalists pick their favourite Nobel awards from the past. Here Matin Durrani argues the case for the ...

What is Bragg Coherent Diffraction Imaging? Bragg coherent diffraction imaging (BCDI) is a powerful X-ray imaging technique that allows researchers to visualize the internal structure and strain ...

Oxygen, the colorless and odorless gas that is essential to the survival of humans and other living organisms, is estimated ...

Proceedings of the Royal Society of London. Series A, Mathematical and Physical Sciences, Vol. 293, No. 1433 (Jul. 26, 1966), pp. 169-180 (16 pages) The selected area electron diffraction patterns ...

A newly developed experimental set-up allows the structure determination of biomolecules such as proteins with far smaller samples and shorter exposure times than before at synchrotron X-ray sources.

The global oil trade is a complex and highly lucrative industry that relies on accurate analysis of crude oil samples. Ensuring the quality, origin, and authenticity of oil samples is crucial for ...

I know, this is being picky, but the double helix structure of DNA was not proposed based on a crystal structure. DNA oligonucleotides suitable for crystallization were not available to Wilkins and ...

With this new, unique X-ray machine, NIST can make some of the world's most accurate measurements, and calibrate everyone else's X-rays, too. Researchers at the National Institute of Standards and ...

In a novel example of physics probing beneath the veneer of everyday phenomena, scientists have used X rays to look at the microstructural details of fats as they’re mixed and cooled during food ...

UNDER this title, W. Linnik, of the Leningrad Optical Institute, described in a recent issue of NATURE (April 20) an effect obtained with copper K radiation and a mica crystal. A narrow beam of X-rays ...
