Conventional lithium ion batteries, such as those widely used in smartphones and notebooks, have reached performance limits. Materials chemist Freddy Kleitz from the Faculty of Chemistry of the University of Vienna and international scientists have developed a new nanostructured anode material for lithium ion batteries, which extends the capacity and cycle life of the batteries.

Realization Of High-Performance Magnetic Sensors Due To Magnetic Vortex Structures
Many modern technological applications are based on magnetic forces, e.g. to move components in electric vehicles or to store data on hard disks. Yet magnetic fields are also used as sensors to detect other magnetic fields. The total market for magnetic field sensors based on semiconductor technology currently amounts to USD 1,670 million and continues […]
Three ‘Twisted’ Photons in Three Dimensions
Researchers at the Institute of Quantum Optics and Quantum Information, the University of Vienna, and the Universitat Autonoma de Barcelona have achieved a new milestone in quantum physics: they were able to entangle three particles of light in a high-dimensional quantum property related to the ‘twist’ of their wavefront structure. The results from their experiment […]
Invisible Tool Enables New Quantum Experiments
Matter wave interferometry has a long standing tradition at the University of Vienna, where the first quantum interference of large molecules has already been observed in 1999. Nowadays scientists are hunting down evidence for the quantum mechanical behavior of increasingly complex constituents of matter. This is done in experiments in which the flying of each […]
Photos of the Day: Old Uranium, New Research
A team of three researchers based in Austria and Australia lead by Stephan Winkler have identified the bomb-pulse of this isotope in corals from the Caribbean Sea. Uranium is readily dissolved in seawater, and therefore is carried by ocean currents. This makes uranium-236 and ideal tool for investigating ocean currents. Read the full story here. […]
Investigating Ocean Currents Using Uranium-236 from the 1960s
In the period of atmospheric nuclear testing in the 1950s and 1960s significant amounts of uranium-236 were distributed world-wide. Despite this, uranium-236 has mostly eluded detection and clear attribution to this source. A team of three researchers based in Austria and Australia lead by Stephan Winkler have identified the bomb-pulse of this isotope in corals […]
