Quantum chemistry on quantum computers

Quantum computing and quantum information processing technology have attracted attention in recently emerging fields. Among many important and fundamental issues in science, solving the Schroedinger equation (SE) of atoms ...

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 ...

Physics discovery unlocks ingredients of 2-D 'sandwich'

Everything that exists in the digital world—photos, tweets, online courses, this article—is stored as 1's and 0's. At the software level, this information is written as computer code. At the hardware level, that code ...
