Gold makes invisible surfaces visible in CT

New method for displaying previously invisible surface details using computer tomography developed

10-May-2019 - Today, the three-dimensional visualization and analysis of biological samples using computer tomography (CT) is a routine procedure. However, in the past it was very difficult to visualize the fine surface details of many organisms. Scientists at the Universities of Cologne and Bonn and the ...

Soft Probing with Optical Tweezers

Researchers have developed a method for measuring soft, structured surfaces using optical forces

13-Oct-2015 - Surfaces separate outside from inside, control chemical reactions, and regulate the exchange of light, heat, and moisture. They thus play a special role in nature and technology. In the journal Nature Nanotechnology, the Freiburg physicist Prof. Dr. Alexander Rohrbach and his former PhD candidate ...

Volcano pollution could lead to Parkinson’s misdiagnosis

11-Jun-2013 - Research suggests that the effects of pollution from eruptions from Mount Etna could be leading to misdiagnosis of Parkinson’s disease in the surrounding area. Scientists in Italy used X-ray photoelectron spectroscopy (XPS) for the first time to investigate the chemical composition of the surface ...
