What would you use to try and find an underground water leak, your ears or radar? Believe it or not the only way to find water leaks involves trying to hear the hiss of the leak through a device like a stethoscope. This antiquated system could soon be a thing of the past as a fast and full-proof method using radar is being developed thanks to an investment of £76,810 from NESTA (the National Endowment for Science, Technology & the Arts), the organisation that invests in UK creativity and innovation.
The StesT Leak Radar is the brainchild of Dr Mark Harper, who has 30 years’ experience in applied physics and geophysics. Cambridge company STesT (Structural Testing Technology) Ltd also includes Dr Martin Thompson, an engineer who has worked in the mining and energy industries since 1975, and John Sheppard, a mechanical engineer with 20 years’ experience.
The present method of finding leaks in water mains involves looking at suspected damage areas at night and narrowing down an area through acoustic detection of the hiss produced by the leak. It is finally pinpointed using the listening sticks – lengths of rod that act as stethoscopes. This final step is time consuming and error prone, with other noises often hindering the discovery of any leaks. It can easily be misled by hissing noises arising from valves, ferrules, and other obstacles to water flow.

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...
