Physicists in the UK are ready to start construction of a major part of an advanced new experiment, designed to search for elusive gravitational waves. They are already part of two experiments: the UK/German GEO 600 project and the US LIGO experiment (Laser Interferometer Gravitational-Wave Observatory), both in their commissioning phases. By bringing GEO 600 technology to LIGO, they and their German colleagues from the Albert Einstein Institute are now set to become full partners in Advanced LIGO, a more sensitive observatory that once fully operational should be able to detect a gravitational wave event a day.
Gravitational waves should be created when massive objects, such as black holes or neutron stars in astronomical binaries interact and spiral-in towards, and eventually collide with, each other emitting a strong burst of gravitational radiation or when a star, at the end of its long evolutionary phase, collapses due to its own gravity resulting in a supernova with the core forming a neutron star or a black hole. Rapidly rotating neutron stars or pulsars with tiny
deformities in their spherical shape, and newly formed neutron stars, are continuous emitters of the radiation. There should also be background "noise" made up from a population of such events and, possibly, phase transitions in the early Universe and the echoes of the Big Bang itself.
First predicted by Einstein’s Theory of Relativity, gravitational waves have never been observed, but indirect evidence of their existence has been obtained by measuring the effect of their emission by a binary pulsar system (two neutron stars orbiting each other). The observed effect was found to match predictions.

Friction stir welding is a still-young and thus often unfamiliar pressure welding process for joining flat components and semi-finished components made of light metals.
Scientists at the University of Stuttgart have now developed two new process variants that will considerably expand the areas of application for friction stir welding.
Technologie-Lizenz-Büro (TLB) GmbH supports the University of Stuttgart in patenting and marketing its innovations.

Optical quantum computers can revolutionize computer technology. A team of researchers led by scientists from Münster University and KIT now succeeded in putting a quantum optical experimental set-up onto a chip. In doing so, they have met one of the requirements for making it possible to use photonic circuits for optical quantum computers.
Optical quantum computers are what people are pinning their hopes on for tomorrow’s computer technology – whether for tap-proof data encryption, ultrafast...
The Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP has been developing various applications for OLED microdisplays based on organic semiconductors. By integrating the capabilities of an image sensor directly into the microdisplay, eye movements can be recorded by the smart glasses and utilized for guidance and control functions, as one example. The new design will be debuted at Augmented World Expo Europe (AWE) in Berlin at Booth B25, October 18th – 19th.
“Augmented-reality” and “wearables” have become terms we encounter almost daily. Both can make daily life a little simpler and provide valuable assistance for...
With the help of artificial intelligence, chemists from the University of Basel in Switzerland have computed the characteristics of about two million crystals made up of four chemical elements. The researchers were able to identify 90 previously unknown thermodynamically stable crystals that can be regarded as new materials. They report on their findings in the scientific journal Physical Review Letters.

For the first time, Fraunhofer IKTS shows additively manufactured hardmetal tools at WorldPM 2016 in Hamburg. Mechanical, chemical as well as a high heat resistance and extreme hardness are required from tools that are used in mechanical and automotive engineering or in plastics and building materials industry. Researchers at the Fraunhofer Institute for Ceramic Technologies and Systems IKTS in Dresden managed the production of complex hardmetal tools via 3D printing in a quality that are in no way inferior to conventionally produced high-performance tools.
Fraunhofer IKTS counts decades of proven expertise in the development of hardmetals. To date, reliable cutting, drilling, pressing and stamping tools made of...
