Researchers devised a method that opens up new scales of tomographic imaging and will thus make the detailed study of representative volumes of biological tissue and materials science specimens possible in future.
Researchers have experimentally demonstrated that interferometers, the most sensitive measuring instruments yet invented, can be improved using nonlinear physics. The result answers a fundamental question in quantum mechanics and could open the way to more sensitive detection of magnetic fields in delicate systems such as the human heart.
They are invisible, but perfectly suited for analysing liquids and gases; infrared laser beams are absorbed differently by different molecules. This effect can for instance be used to measure the oxygen concentration in blood. This technique has now been miniaturized and implemented in the prototype for a new kind of sensor.
Developments in nanotechnology, achieved through the EU-funded IP NANOKER project, mean that new multifunctional materials can be manufactured at competitive prices. This has the potential to transform industries ranging from medicine to aeronautics.
Material researchers present a composite material which prevents metal corrosion in an environmentally friendly way, even under extreme conditions. It can be used wherever metals are exposed to severe weather conditions, aggressive gases, media containing salt, heavy wear or high pressures.
Prozesse, die auf atomarer Grössenskala ablaufen, lassen sich nur mit den Gesetzen der Quantenmechanik genau beschreiben. Physikern der Universität Würzburg ist es jetzt erstmals experimentell gelungen, den Zustand eines solchen quantenmechanischen Systems vollständig zu erfassen.
By levitating a bead of ceramic oxide, heating it with a 400-watt carbon dioxide laser, then shooting the molten material with X-rays and neutrons, scientists have revealed unprecedented detail of the structure of high-temperature liquid oxides.
Engineers have successfully shown that a continuous flow reactor can produce high-quality nanoparticles by using microwave-assisted heating - essentially the same forces that heat up leftover food with such efficiency.
