The samples were chemically cleaned, burned to produce carbon dioxide, catalytically converted into graphite and then tested for carbon 14 isotopes to fix the date by calculating .
The dance of the atoms ( Vienna University of Technology ) Taking pictures of individual atoms allows scientists at the Vienna University of Technology to find out how catalysts behave and how atoms on a surface tend to ball together. For the first time, this clustering effect can be directly observed. In catalysts, this effect is a serious problem: Once the atoms cluster, they are not catalytically active any more ...

Susan Lindquist in Science Daily (press release) These proteins are remarkably stable,says Susan Lindquist, director of Whitehead and lead researcher on the project. "This is the first time that anyone has found anything that can catalytically take apart an amyloid fiber."
