By their very nature, sunlight and wind, as renewable sources of energy, fluctuate in intensity. Intelligent power grids and energy storage systems are essential in order to compensate for these fluctuations and ensure a secure supply of power from renewable … Weiterlesen …
Chicken eggs are used worldwide in large quantities in the food, pharmaceutical, and manufacturing industries, and for household purposes. However, after the egg is used, the shells are discarded and disposed of as bio-waste in landfills. The shell consists of … Weiterlesen …
It all starts with an ear. Empa researcher Michael Hausmann removes the object shaped like a human ear from the 3D printer and explains: “In viscous state cellulose nanocrystals can easily be shaped together with biopolymers into complex 3-dimensional structures using a … Weiterlesen …
“I have been enormously lucky in life, and I wish to give some of that luck back,” the 29-year-old Gnanli Landrou from Togo explains. His firm determination leaves no room for doubt: this young man will follow through with his … Weiterlesen …
TVs and smartphones that project digital images emit light all around them, as quasi-isotropic sources. Because the images are projected generally over the air without directivity, many viewers see the same image. In typical AR glasses, images are transmitted close … Weiterlesen …
Researchers at Carnegie Mellon University are studying soft magnetic materials to make hard changes to motors. Through synthesizing metal amorphous nanocomposite materials (MANCs), their goal is to make smaller motors that deliver comparable power. “The power of a motor depends on its … Weiterlesen …
Noch nie haben wir den Klimawandel so hautnah erlebt, wie in diesem Sommer. Auch der zunehmende Güterverkehr trägt zur Veränderung des Klimas bei. Auf der Suche nach Auswegen aus diesem Dilemma fällt der Blick auf BETTERFLOW, einem Start-up aus Aachen. … Weiterlesen …
Prof. Reineke and his team at the Dresden University of Technology work with simple plastic foils with a thickness of less than 50 µm, which is thinner than a human hair. In these transparent plastic foils, they introduce organic luminescent molecules. In the … Weiterlesen …
A better performance, lower costs, and enhanced safety compared to lithium-ion batteries: these are the hopes of scientists at the Karlsruhe Institute of Technology (KIT) and their cooperation partners in relation to novel magnesium batteries. Compared to conventional lithium-ion batteries, a magnesium … Weiterlesen …
The erosion of wind turbine blade material is a costly problem. “The blade material erodes due to the effect of rain, hailstones, and sand dust, which significantly reduces the service life of wind turbines. Accelerated replacement of turbines becomes expensive: … Weiterlesen …
