Capillary holder in action

To the States, and other cutting-room clippings

Dear readers,

As you read this, I’ll be trying to get to the Denver X-ray Conference in Montana. I’ll be giving a talk there on Friday morning introducing small-angle scattering to fellow X-ray afficionados and hopefully convert a soul or two to the narrow field we’re in. Please come and say hi if you’re around, or contact me on my twitter account (connectivity permitting), user @drheaddamage. I have two small bits I want to talk about today: a new sample holder and 3D SAXS. Read More

Data corrections implemented up to now (green) out of total listed in "Everything SAXS"-paper.

1/2 – year update

Indeed, we are already prety much halfway through the useful part of 2014, considering the latter half of December is a globally recognised period for scientific procrastination. It’s also a good time now to quickly give you an update about some of the things transpiring here. Read More

One of the catalyst materials synthesized from gelatine, in which the porous "foam-like" structure is clearly visible.

Green catalysts from pigs!

This news has also been covered by Birmingham University, Martin Hollamby and The Schnepp Group, and may appear in other news outlets soon. [update: like at, the Mumbai mirror, FuelCellsWorks, supergen fuel cells, green car congress and update2: Some more selected outlets: Ars Technica, the Conversation, World of Chemicals, Renewables Europe, Hydrogen and Fuel Cell letter (paywalled), and The Himalayan Mirror ]

Imagine you could turn pigs into catalysts. You’d think that that would take quite some work, but it turns out to be surprisingly easy as long as you have a good oven and some salts lying around. This has been demonstrated by Zoe Schnepp (of the newly formed Schnepp Group at the U. of Birmingham) in collaboration with Yuanjian Zhang, Martin Hollamby and others during her time here at NIMS, and has just been published here. So what did we do?… Read More

Recorded at 30 kV, 10mA, using the collimation crystal

The Bonse Hart instrument works!

Ok, so let’s start with the disclaimer: very initial results (fresh off the instrument, hence the delay), and the primary beam intensity is still very, very weak (flux at sample position: ~5kHz, at 10% generator power). Background detection level is typically on the order of 1 Hz. Read More


Slight delay.

My apologies for not having a post ready this week, I wanted to post about instrument alignment and how amazingly well it works, but it turns out machine alignment isn’t all that easy. As another post was not yet complete either, I have to take a raincheck and update soon again!

Sorry for the delay!
