A new strategy to investigate quantum entanglement up to thousands of particles A team of physicists from ICTP-Trieste and IQOQI-Innsbruck has come up with a surprisingly simple idea to investigate quantum entanglement of many particles. Instead of digging deep into the properties of quantum wave functions - which are notoriously hard to experimentally access - they propose to realize physical systems governed by the corresponding entanglement Hamiltonians .

In chemistry, atoms can usually only affect their immediate neighborhood. At TU Vienna, a novel effect with astonishing long-range action has been discovered, which can make automotive catalytic converters more effective.

Electrodes for longterm monitoring of electrical impulses of heart or muscles in the form of temporary tattoos produced using an ink-jet printer. An international research group involving TU Graz presents this novel method in Advanced Science. available at the end of the text In the case of diagnostic methods such as electrocardiogram (ECG) and electromyography (EMG), gel electrodes are the preferred method of transmitting electric impulses from the heart or muscle.

TU Wien and Sandoz GmbH have successfully implemented a real-time computer simulation of the complex growth behaviour of penicillin producing organisms. This simulation now helps to keep the production process under control. For thousands of years, micro-organisms have been used to facilitate chemical reactions - in beer brewing, for example.

How do you combine different elements in a crystal? At TU Wien, a method has now been developed for incorporating previously unattainably high proportions of foreign atoms into crystals. When you bake a cake, you can combine the ingredients in almost any proportions, and they will still always be able to mix together.

Scientists from TU Wien (Vienna, Austria) and the USA have provided proof for a new state of matter: an electron orbits a nucleus at a great distance, while many other atoms are bound inside the orbit. The electron (blue) orbits the nucleus (red) - and its orbit encloses many other atoms of the Bose-Einstein-condensate (green).

Storing information in a quantum memory system is a difficult challenge, as the data is usually quickly lost. At TU Wien, ultra-long storage times have now been achieved using tiny diamonds. At some locations in the crystal lattice, a carbon atom (white) is missing, and at the neighbouring site there is a nitrogen atom (yellow).

Spectacular electron microscope images at TU Wien lead to important findings: Chemical reactions can produce spiral-like multi-frequency waves and thus provide local information about catalysts. They appear almost hypnotic, like a lava lamp. The waves made visible at TU Wien using a photoemission electron microscope cover the surface of rhodium foil with bizarre patterns which dance around on the surface.
