In collaboration with KEMA, two postgraduate students from Eindhoven University of Technology have developed a device that continuously monitors cables to localize weak points in distribution networks. Data on weak point development and location enables an electricity company to pre-empt problems by timely intervention. This in turn enhances network reliability and reduces costs. With their invention, Jeroen Veen and Peter van der Wielen received in April their doctorate degree at the Eindhoven University of Technology.
Most power network faults are down to defective distribution cables. Electricity companies therefore try to identify weak spots in cables and replace them before short circuits occur. At present, this is done by carrying out periodic checks on critical cables during maintenance shutdowns. As well as being time-consuming and expensive, this process is far from entirely reliable. In the future, however, electricity companies will be able to cheaply and continuously monitor the quality of vital cables while they remain in use, thanks to research undertaken by Jeroen Veen and Peter van der Wielen. The postgraduate duo has developed a working prototype that has now been adopted by a manufacturer.

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
