A little step sideways from small-angle scattering for this week’s post. As you are probably aware by now, I sometimes use the LaN weblog to […]

left: Fourier components and low- and high-pass window. Right: original data, low-pass filtered data, and high-pass filtered data.

Error estimation using Fourier Transforms

Estimating uncertainties on data values has always been an important and under-emphasized part of small-angle scattering. Uncertainties are critical to your data: they tell you […]

So there is an “Everything SAXS”-book, and it is empty!

2014-11-04 Brian Pauw 5

For a while now, I have wanted to write a book about SAXS, introducing the topics, explaining the details, and including many of the more […]

Table showing which model can be used to fit scattering patterns from a variety of polydisperse shapes.

Spheres, rods, discs, which can fit what?

2014-10-27 Brian Pauw 1

A remark in a recent paper by Dr. Yojiro Oba (currently at KURRI) caught my attention. It discusses which shape assumption can be appropriate to […]

General idea of contrast matching core-shell particles in a gradient

Contrast-variation SAXS

2014-10-20 Brian Pauw 0

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 […]
