Organogels: New cleaning agent for artworks
The restoration of artworks often involves solvents which have toxic properties. Now researchers have succeeded for the first time in creating a non-toxic and sustainable cleaning agent for paintings.
Pollution
Grimy windows could be harbouring toxic pollutants
Dirty windows can harbour potentially harmful pollutants under protective films of fatty acids from cooking emissions – and these can hang around over long periods of time.
Neutrons detect air pollution
Portuguese scientists have analysed lichens from areas with traditional charcoal production for the first time with the help of the Research Neutron Source Heinz Maier-Leibnitz (FRM II) of the Technical University of Munich (TUM). Lichens located near areas of charcoal production contained more than twice the concentration of phosphorus, which is generated during the combustion process.
