Precious metal-free silicone curing

Sustainable processes could replace precious metals in silicone crosslinking

03-Dec-2020 - Silicones are tried and tested in the private and professional domains. In many applications, however, expensive precious metals are required as catalysts to transform the liquid intermediate products to durable elastic polymers. A research team from the Technical University of Munich (TUM) and ...

Neutrons make structural changes in molecular brushes visible: Promising candidates for a variety of applications

02-Nov-2020 - They look like microscopic bottle brushes: Polymers with a backbone and tufts of side arms. This molecular design gives them unusual abilities: For example, they can bind active agents and release them again when the temperature changes. With the help of neutrons, a research team from the ...

Superatoms as catalysts

Prof. Roland Fischer awarded Reinhard Koselleck Project funding from the DFG

05-May-2020 - Precious metals like platinum are good catalysts – but they are expensive. While the chemical industry is trying to solve this cost issue by developing ever-smaller catalyst particles, a team from the Technical University of Munich (TUM) is taking an entirely new approach: the targeted ...

Photochemical deracemization of chiral compounds achieved

The vanished mirror image

20-Dec-2018 - Enantiomeric molecules resemble each other like right and left hands. Both variants normally arise in chemical reactions. But frequently only one of the two forms is effectual in biology and medicine. Hitherto, completely converting this mixture into the desired enantiomer was deemed impossible. ...
