Contrast-variation SAXS

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 [1] […]

Tele-SAXS Beamtime with on-the-fly data corrections.

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 […]

Preparing for Beamtime

One more burst of beamtime is coming up at the end of this week. This one will be with Zoë, Martin and Ashleigh once more, but there is one big difference: I ran out of funding, so I won’t be there!

Video: “Applied Metrology of Small-angle Scattering”

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.

Guinier in polydisperse systems revisited

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.

Applications of SAXS: Self-assembled Structures

[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 […]

Update tomorrow

Dear readers, unfortunately, my video recording for this week needs a bit more editing than I had spare time for today. It’ll be done tomorrow. See you then!

Applications of SAXS: Fibres

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.

Applications of SAXS: Metal alloys

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.

Applications of SAXS: Catalysts (Video)

Hi all, I have started recording parts of the presentation I have given throughout this year. One part of the presentation consists of a number of application examples of SAXS. Herewith the first of the examples involving catalysts.
