Travel part 3: Diamond and Nottingham

The third part of the travel consisted of experiments and one final talk to top it all off.

Travel part 1: York and Leeds

York and Leeds, the first 40% of the presentations all done. Still to go: Lille, Birmingham and Nottingham, and a few synchrotron days in between. Read on for the experiences at the first two places:

Back from holiday and SAS2012

SAS2012 turned out to be quite amazing, and I had a blast! After the conference some weeks were spent on holiday and therefore this site did not get updated. There should be new stuff coming up in a week. Cheers!

Lessons in outreach to be learned from Japan’s disasters

(warning: this rather lengthy piece may contain personal opinions and has little to do with small-angle scattering. There is a nice bit about graphics, though.)   In the wake of the global public panic following the reporting around the nuclear reactor struggles (as opposed to the expected >15 kilopeople deaths in Myagi prefecture due to […]

Live FT video

A demonstration of the live Fourier Transform showing scattering patterns can be seen here:

Live Fourier transform

During some recent presentations, I have used a small matlab program giving me a live Fourier transform of the laptop camera input. It can be used in combination with some printed “structures” to show what we would see on a SAXS or WAXS detector. The idea is not mine, I heard that it was used […]

Notes on Guinier

…well, his famous SAXS analysis method. This documentGuinier_short, copyright Brian Pauw gives a short description and review of the applicability of the Guinier method to polydisperse systems. It also shows, through analysis of simulated data, what q-range should be measured for the Guinier method to be valid. In short, the rule of qmax=1.3/Rg still holds, […]

More Youtube videos

So, I could not do what I promised last time, the Monte-Carlo fitting works on perfect simulated scattering patterns but is as of yet unable to deal with the addition of a flat background. So I will have to take a raincheck. In the mean time, I have made two videos (part 1 and part […]

Teaching and how it applies to us.

We teach. Every one of us. If we have a classroom of students, it is obvious, but also when we talk to colleagues, we sometimes try to teach them something (even if it is only our point of view). I spoke last time about the teaching horrors that modern textbooks have. Well, this video by […]
