Researchers develop new method for X-ray colour imaging

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 ...

Using X-rays to identify liquid chiral molecules

New method can for the first time distinguish their components in liquid form – and more effectively than ever before

25-May-2022

Sugars, amino acids, drugs - chiral molecules are everywhere. Researchers in the AQUACHIRAL project at the Fritz-Haber-Institut have used X-rays to study hair-thin liquid jets of these molecules. Using a new method, they can now for the first time distinguish their components in liquid form – and ...

Soft X-ray method promises nanocarrier breakthroughs

Before the huge potential of tiny nanocarriers for highly targeted drug delivery and environmental clean-up can be realized, scientists first need to be able to see them

27-May-2021

Currently researchers have to rely on attaching fluorescent dyes or heavy metals to label parts of organic nanocarrier structures for investigation, often changing them in the process. A new technique using chemically-sensitive "soft" X-rays offers a simpler, non-disruptive way of gaining insight ...
