Quantum predictions

Solving a complex problem quickly requires careful tradeoffs – and simulating the behavior of materials is no exception. To get answers that predict molecular workings feasibly, scientists must swap in mathematical approximations ...

Tailor-made synthesis of cyclic chemicals by means of enzymes

Penicillin-based antibiotics contain a five-membered hydrocarbon cycle, additionally incorporating a sulfur and a nitrogen atom. Nadine Zumbrägel, doctoral student at the Chair of Organic Chemistry I at Bielefeld University, ...

Molecular motor: Four states of rotation

With the help of ultrafast spectroscopy and quantum mechanical calculations, Ludwig-Maximilians-Universitaet (LMU) in Munich researchers have characterized the complete rotational cycle of the light-driven, chemical motor ...

Supercomputing more light than heat

Solar cells can't stand the heat. Photovoltaics lose some energy as heat in converting sunlight to electricity. The reverse holds true for lights made with light-emitting diodes (LED), which convert electricity into light. ...

New molecules for OLEDs and pharmaceuticals

Chemists from Ural Federal University (UrFU, Ekaterinburg) have suggested a new technique for synthesizing thiophene derivatives and studied their fluorescent properties experimentally as well as theoretically. Many organic ...
