Colour images from the shadow of a sample

25-Jan-2023

A research team at the University of Göttingen has developed a new method to produce X-ray images in colour. In the past, the only way to determine the chemical composition of a sample and the position of its components using X-ray fluorescence analysis was to focus the X-rays and scan the whole ...

Saved seconds add up to hours over multiple measurements

10-Jan-2023

How can the component elements of an unknown material, such as a meteorite, be determined? X-ray fluorescence analysis can be used to identify an abundance of elements, by irradiating samples with X-rays and analyzing the spectrum they emit and can detect many elements simultaneously. For this ...

Microplastics are everywhere, even in the most remote places. Where do these tiny pieces of plastic come from?

01-Dec-2021

Microplastics are an environmental problem since organisms ingest these tiny particles and can be harmed by them. Even remote regions such as Antarctica are affected. To quantify this form of pollution and find out where the small particles come from, a research team from the Department of ...
