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 ...

X-ray crystallography is a powerful non-destructive technique for determining the molecular structure of a crystal. X-ray crystallography uses the principles of X-ray diffraction to analyze the sample ...

Diffraction-based analytical methods are widely used in laboratories, but they struggle to study samples that are smaller than a micrometer in size. Researchers have nevertheless been successful in ...

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 ...

(Nanowerk News) Understanding how chemical reactions happen on tiny crystals in liquid solutions is central to a variety of fields, including materials synthesis and heterogeneous catalysis, but ...

Diffractometers have been around for a long time and are used to analyze various types of materials and provide information regarding their structure. While there are a few different types, we’re ...

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 ...

Oxygen, the colorless and odorless gas that is essential to the survival of humans and other living organisms, is estimated to make up around 21% of Earth's atmosphere. While the primary properties of ...

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 ...

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 ...
