Contrast variation is commonly used in SANS to highlight a single segment of a mutli-part structure. In SANS it is easy to do this because a wide range of scattering length densities can be accessed by simple mixing of water and deuterated water. In SAXS this is not so easy. A recent arXiv paper  by Raul Garcia-Diez, however, shows one method for getting it done in SAXS. Read more »
This has been a very interesting last couple of days. I was unable to join Zoë Schnepp and Martin Hollamby for our SAXS beamtime at Diamond. Instead, I decided to try and join in from abroad. The plans were ambitious: to do on-the-fly high-quality data correction and analysis. In the end there we achieved partial success.
Another video, and this one was a bit sizeable. The video is the majority of the introduction of my talk series for this year. The “Applications of SAXS”-series was part of the same. This introduction touches on a variety of topics, including one thing I have not yet talked to you much about: stripy nanoparticles. Read more »
Last week, I was contacted by Christian Gollwitzer (author of this excellent paper) about something posted here (and in particular detailed in this document) a while ago. It concerns the behaviour of the Guinier approxiation for polydisperse systems, and it looks like I made a mistake when writing that document. Read more »
[Ed: It looks like there is more interest than I thought in the field of SAXS; the “Everything SAXS” review paper has been downloaded over 10000 times!]
One more application we found for small-angle scattering was to research structures molecules assemble in when immersed in liquids. Many of us are familiar with the micellar structures that appear in water-based solutions, but what happens in other solvents? Read more »
I started working with small-angle scattering when investigating fibres during a (fun) company internship at Teijin Aramid. The most recent developments of our work in that field is summarized in this video to show SAXS applications in that field. Read more »
This week another segment of my presentation, recorded in a slightly different format this time (hopefully for the better, the previous one on SAXS on catalysts can be seen in this post). This time, I discuss an application of SAXS application in the field of metallurgy. Read more »
