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.

At the Hannover Messe 2018, the Bundesanstalt für Materialforschung und-prüfung (BAM) will show how, in the future, astronauts could produce their own tools or spare parts in zero gravity using 3D printing. This will reduce, weight and transport costs for space missions. Visitors can experience the innovative additive manufacturing process live at the fair.
Powder-based additive manufacturing in zero gravity is the name of the project in which a component is produced by applying metallic powder layers and then...
Physicists at the Laboratory for Attosecond Physics, which is jointly run by Ludwig-Maximilians-Universität and the Max Planck Institute of Quantum Optics, have developed a high-power laser system that generates ultrashort pulses of light covering a large share of the mid-infrared spectrum. The researchers envisage a wide range of applications for the technology – in the early diagnosis of cancer, for instance.
Molecules are the building blocks of life. Like all other organisms, we are made of them. They control our biorhythm, and they can also reflect our state of...
University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.
Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.
Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.
Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...
Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.
The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...
