Calculating scattering by hand – example 1

Those who read the older SAXS literature will note liberal use of Fourier transforms to calculate the scattering behaviour of odd-shaped particles. Likewise, the effects of smearing due to (for example) beam shape (think “blurring” of the scattering pattern) can be easily determined using such transforms. It is useful to get a feel for the […]

February roundup: BH rebuild progress, paper news.

The end of February is nigh (shockingly fast…), and so it is time for another round-up. This month, the following things piqued my interest:

Why we never may be able to get a calibration curve: a matter of coherence

For years, we have been trying to compare scattering patterns from different instruments. While this leads to reasonable results, there are precious few cases of true agreement despite the focus on data corrections (one example of agreement: [0]). My guess: we have not been considering coherence in these comparisons. This paper is currently available for […]

Radiation safety for lab X-ray sources

Over the years, I have followed several radiation safety courses in a variety of countries. Last week, it was NIMS’ turn to train me. As this was given in Japanese (a language I can only half follow), I decided to write my own section on radiation safety instead (for future inclusion in the book). This […]

January roundup: Sour scientists, McSAS logo, CanSAS meeting

A few short stories for today, none of them really long enough to fill a blog post with, and therefore better combined for your enjoyment.

Everything SAXS – book growth

Finally, I managed to get some time to work on the book again. When I last left it late December, the book structure and base was complete, but its content was missing. This is what I did so far:

Dr. Helen E. Maynard-Casely chats about planets

What to expect on the surfaces of the more distant planets is a hard question to answer. Fortunately, we have scientists working on this problem. At our institute, we just had the pleasure of hosting a talk by Dr. Maynard-Casely, whose mission is to add a certain amount of evidence-based level-headedness to the discussions. I […]

Plastic Fantastic Project: printing an Ultra-SAXS machine.

You wouldn’t steal a SAXS machine… Because you can print one! For the last few weeks, I have been playing around with a new little 3D printer in my lab. This one can print structures in ABS plastic, so I thought it would at least be useful for sample holders. Then I started experimenting a […]

It is the year that will be (2015 edition).

With 2015 already 2% done by the time you read this, you must be wondering what events you can expect from LaN for 2015. Without further ado, a listing of just that:

It was the year that was (2014 edition).

Recap time! As the years before, 2014 has been a good year for LaN and me. As you know, this year I moved from a twice monthly post to a mostly weekly post, making this the 56th post this year (if my count is correct). Let’s take a look at some of them.
