Electronic sensors can benefit many industrial applications, such as automotive engineering. But they have to be protected from attacks and falsifications. The new joint project “sensIC”aims to integrate printed electronics and silicon components directly into products in order to secure sensors. At the Karlsruhe Institute of Technology (KIT), researchers are developing a central component for this: printed safety circuits with special hardware-based functions, so-called Physical Unclonable Functions (PUFs). The Federal Ministry of Research is funding sensIC with a total of 2.9 million euros. The industrial partners are investing a further 1.35 million euros in the project.
In electrically powered vehicles, they monitor the temperature of the batteries in order to optimize their service life and performance; in plants in the chemical and pharmaceutical industries, they monitor the operating status of passive components in order to detect errors immediately: Electronic sen

High-temperature technologies enable electrothermal storage systems for large amounts of energy from renewable sources. Karlsruhe Institute of Technology (KIT), the German Aerospace Center (DLR), and the industry partner KSB have now launched the LIMELISA project to develop the necessary basis. Research is funded with EUR 3.8 million by the Federal Ministry for Economic Affairs and Energy.
Every year, wind parks and solar facilities in Germany produce thousands of gigawatt hours of power that cannot be used directly and therefore remain unused. At other times, lacking capacities are compensated by energy from fossil sources. Large-scale electrothermal storage systems may solve this problem and additionally enhance grid stability. The idea is to convert power into heat, to

In the 1930s, the French physicist Pierre Auger placed Geiger counters along a ridge in the Alps and observed that they would sometimes spontaneously click at the same time, even when they were up to 300 meters apart. He knew that the coincident clicks came from cosmic rays, charged particles from space that bang into air molecules in the sky, triggering particle showers that rain down to the ground. But Auger realized that for cosmic rays to trigger the kind of enormous showers he was seeing, they must carry fantastical amounts of energy so much, he wrote in 1939, that “it is actually impossible to imagine a single process able to give to a particle such an energy.”

Tungsten has the highest melting point of all metals, 3,422 degrees Celsius. This makes the material ideal for use at high temperatures in e.g. space rocket nozzles, heating elements of high-temperature furnaces, or the fusion reactor. However, the metal is highly brittle and, hence, difficult to process. Researchers of Karlsruhe Institute of Technology (KIT) have developed an innovative approach to making this brittle material soft. To process tungsten, they have determined new process parameters for electron beam melting.
Tungsten is a metal with very attractive properties: It is corrosion-resistant and as heavy as gold. In the form of tungsten carbide, it is as hard as diamond. And it has the highest melting point of all metals, 3,422 degrees Celsius. However, the metal is highly brittle at room temperature. Due to its properties, tungsten is dif
