DXC review

The Denver X-ray conference was quite excellent, mostly becauase of the people to talk to during the coffee breaks and the dinners (as always, there should be more of these and longer!). Here’s my quick review of the conference:

Nature Chemistry publishing on Martin’s Magical Molecules

The long wait is over! A new publication is out, this one written by Martin Hollamby over the course of three tough years. For those who haven’t seen his one-minute intro video, Martin is investigating the behaviour of molecules in solvents. In his excellent paper, he shows how his range of molecules can self-assemble in (hydrophobic) […]

Thank you for a wonderful 2013!

It seems like this year has flown by at an amazing speed, yet quite a few things have come to pass in this year.

The value of years: good stories and advice from M. H. J. Koch

One paper I managed to miss for my review paper on data corrections is a paper by M. H. J. Koch from Hamburg. The paper is written in a nice informal way, replete with good quotes, where he talks about his experiences in instrument development for SAXS and WAXS beamlines. In particular the paper details […]

A comparison of Quality in neutron scattering

By the way, my topical review paper on SAXS data collection and correction has been published and is available open access here! Ensuring that a measurement gets you the right values is quite important for any scientist. One way of finding out what the quality of your machine is, is to compare your results for a […]

Programming your own data reduction? Check out fabIO and pyFAI

Reading in the detector data, and programming methods for that, is one of the more tedious tasks of any data reduction program. Those of you who write their own data correction programs know this all too well. Many detector systems store their data a little bit differently than the others, despite the availability of decent […]

A review of data collection and correction procedures.

Following my previous work in progress detailing the data correction steps to obtain good data, I finally had the chance to write this down in a review article. This review article (open access) has been submitted on Monday. After it has been reviewed and (hopefully) published in the journal, I will ensure that that latest version is […]

Comments on Deschamps, 2011 and A clarification on Guinier for Polydisperse systems

After browsing through a recent Journal of Applied Crystallography, I came across a paper by Deschamps. It indicates to me that there is a slight lack of information communication in some aspects of SAXS. Firstly, it mentions in the introduction that the advanced (Fourier-transform-based) SAXS analysis methods cannot “extract simultaneously the precipitate form factor and […]

Book review: Ben Goldacre’s “Bad Science”

Hi all. Last week-end, while visiting friends nearby, a copy of the book “bad science” by Ben Goldacre was dropped in my lap. Having read the occasional post on his weblog (http://www.badscience.net/), I had already planned to get it. So I started reading the book with rather high expectations. (This copy, if I did not misunderstand […]

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, […]
