Nothing new here

So it seems science has beaten us to the punch once again. Remember last week’s optimistic story on how you can make better use of your (measurement) time? Turns out it has been done (at least once) before. The year was 1993, the authors were M. Steinhart and J. Pleštil, and they did the same […]

Making better use of your time: optimizing measurement time

Often, especially when measuring on big facilities, you are given a limited amount of time. So when it comes to measuring the sample and the background, this limited time has to be divided between a measurement of the sample, and a measurement of the background. Normally, one would spend about 50% of the time on […]

capillary self-absorption paper highlight, and new video

Dear scatterers, Those of you who have been reading this weblog for a while now, may remember the calculation of the sample self-absorption correction for plate-like samples. The result of this was a straightforward equation which could be used to correct the scattering of strongly absorbing samples (>30%) with a plate-like geometry. It was mentioned […]

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 […]

One more paper

Do not fret, for I have more software (with documentation!) lined up for presentation on this website soon, but I am still working on the documentation. Please bear with me as I shamelessly promote another publication of mine that came out just days ago. The paper is available here: http://dx.doi.org/10.1016/j.polymer.2010.07.045 It concerns curious observations of […]

Read Ruland and more free reading (textbooks!)

Catching up to current affairs, I stumbled across this beauty. Now, I find this paper starts a little bit chaotic, but very quickly we come across some very useful equations indeed, and a link between the used equation for their analysis of phase transitions in fluids, and various other equations such as the Ornstein-Zernike structure […]

Holiday reading, watching and writing.

Hi all, I found some interesting papers for you, and a talk. Let me start with the talk. It is a TED talk (naturally) concerning TED talks. This nice introspective talk is actually of interest for all of us as it gives a few pointers to the set-up of excellent (and terrible) talks, with a […]

Shameless plug of my own paper

Dear all, the reason I have been silent for a few weeks was that I was waiting for this: Herewith (with a little bit of pride), I would like to present the first paper published as a result of my Ph.D. research. This groundbreaking paper is naturally essential reading for all working in the fields […]

Alternative Ellipsoid Form Factor Function

Just a quick heads up before I start on the ellipsoid form factor alternative: I spoke last post of the efforts for data archiving for possible open-access purposes. Shortly after that post, this news (http://news.bbc.co.uk/2/hi/uk_news/northern_ireland/8623417.stm) appeared. It seems we may be heading (more rapidly than I thought) towards an age where we have to make […]

Particle size distribution: review of “Small-Angle X-ray and Neutron Scattering of Polydisperse Systems: Determination of the Scattering-Particle-Size Distribution”

The determination of the particle size distribution from small-angle scattering curves is usually achieved by assuming a certain statistical size distribution model (f.ex. a Schultz distribution, a Gaussian distribution or a log-normal distribution), and fitting this to the data using a non-linear least-squares optimisation method. Fitting multimodal distributions then implies the addition of multiple contributions, […]
