Initial repulsion does not rule out subsequent attraction

Scientists revealed intricate mysteries of chemical bonding


The Philosopher Arthur Schopenhauer formulated a metaphor called the porcupine dilemma, which explains a certain optimal distance between people. People feel alone at too large a spacing and uneasy at too close a proximity. Schopenhauer explained the ideal spacing using the following parable: „A ...

A long-distance relationship in femtoseconds

Physicists observe how electron-hole pairs drift apart at ultrafast speed, but still remain strongly bound


Modern electronics relies on ultrafast charge motion on ever shorter length scales. Physicists from Regensburg and Gothenburg have now succeeded in resolving a key quantum motion of electrons in atomically thin crystals on the time scale of a single oscillation cycle of light. They directly ...

Physicists watch electron transfer in a single molecule


The building blocks of matter surrounding us are atoms and molecules. The properties of that matter, however, are often not set by these building blocks directly, but rather by their mutual interactions, which are governed by their outer electron shells. Many chemical processes are based on the ...

Feynman Prizes in nanotechnology awarded to Bartosz A. Grzybowski and Franz J. Giessibl


Foresight Institute announced the laureates for the 2016 Foresight Institute Feynman Prizes. Established in 1993, The Feynman prize was named in honor of pioneer physicist Richard Feynman. The prize is given in two categories of nanotechnology, one for experiment and the other for theory. For the ...

A quasiparticle collider

Collision experiments in semiconductors come into reach


Our standard model of the smallest bits of matter rests upon evidence gathered from particle accelerators and collider experiments. A team of physicists from Regensburg (Germany), Marburg (Germany), and Santa Barbara (USA) have now realized a collider for particles in solids. This fundamentally ...

Slow-motion movies of tiny nanostructures

Researchers developed a novel microscope


Physicists from the University of Regensburg have developed a novel microscope that allows them to record slow-motion movies of tiny nanostructures with groundbreaking time resolution – faster even than a single oscillation cycle of light. With their new microscope they have directly imaged the ...

Fast detector for a wide wavelength range


Free-electron lasers are extremely versatile research tools because their intense, super short light flashes permit a closer look at new materials and even biological molecules; thus, allowing effects to be observed that had not been known previously. For pulsed lasers in the far infrared range, ...


BMBF Project NEMO: Research on New OLED Materials Successfully Concluded


After three years of intensive research in the field of new solution-processable materials for OLEDs (Organic Light-Emitting Diodes), Merck and ten other partners from industry and academia have successfully concluded the "New materials for OLEDs from solutions" (NEMO) project co-funded by the ...


Electrons get off the track

Scientists find new principle for spin transistor


Performance of present day electronics is reaching its boundaries since faster transistor operation lead to high power consumption and heat generation. Several alternative schemes are being explored to possibly overcome these limitations, including the use of the electrons’ spin in electronics. ...


New technology for improved OLEDs


The Bayerische Patentallianz GmbH is selling a number of patents of the University of Regensburg to cynora GmbH. Thanks to the new Singlet-Harvesting technique and the use of newly developed emitter materials it will be possible to improve future OLEDs (organic light emitting diodes) and, in ...
