Intermolecular rocking vibrations open up channels for ultrafast singlet fission

The search for new, super-efficient materials to harvest solar energy is a major research focus around the world. Until now, silicon has been the material of choice for solar cells – but scientists are trying to develop far more efficient and cost-effective alternatives. One promising material is pentacene, an organic...

Scientists propose a new technique for the investigation of quasi-particles

The formation and properties of polarons drastically influence the conductivity of technologically relevant materials. Examples include the organic semiconductors found in the ecologically-friendly plastic solar cell technologies. Regarding fundamental physics, polarons are even conjectured to play a crucial role in...

The X-ray flashes of the European XFEL (violet) do not only heat the water (red and white molecules), but also produce a diffraction pattern of the sample (background) from which the state of the water can be determined after each flash. This gives a

Liquid water at 170 degrees Celsius

Using the X-ray laser European XFEL, a research team has investigated how water heats up under extreme conditions. In the process, the scientists were able to observe water that remained liquid even at temperatures of more than 170 degrees Celsius. The investigation revealed an anomalous dynamic behavior of water under...
