The automotive industry is facing major challenges, one of which is reducing fuel consumption and thereby increasing the range of electric cars. While this problem seemingly cannot be solved with a blanket solution, design engineers are increasingly looking to lightweight … Weiterlesen …

3D displays are state-of -the-art technology. For example, we can think of stereo displays capable of conveying depth perception to the viewer. In nature, we can consider the cephalopods – a class of marines animals, which includes the squid and octopus – … Weiterlesen …

In 2018, around 5.6 million electric vehicles were globally registered, which exceeded more than two million vehicles registered in the previous year. This amount has increased more than tenfold since 2013, but the current limitations of batteries still hinders many … Weiterlesen …

Long before the invention of artificial refrigeration, making ice by nocturnal cooling was common. Here, an apparatus consisting of a ceramic tray with a thin layer of water was placed outdoors, and on a clear night, ice would form as … Weiterlesen …

Graphene is a one atom-thick layer of carbon with two dimensional properties. It is a transparent and flexible conductor, and thanks to its extraordinary mechanical strength and excellent conducting properties, it is one of the most promising materials for an … Weiterlesen …

The energy density of hydrogen is roughly 120 MJ/kg, which is much greater than that of chemical, fossil, and biofuels. Water is also the only byproduct when hydrogen is used to produce electricity. Electrolysis could be used to provide high-quality … Weiterlesen …

The worldwide demand for energy is constantly increasing. Until now, oil and coal were still the main sources of energy, but the number of solar systems is growing everywhere. Therewith, also the demand for the materials used is rising. Silicon … Weiterlesen …

Pain is, of course, viewed as something negative, but it has a purpose in that it protects us. Pain is an alarm system that prevents further injuries. Now, researchers aim to transfer this natural alarm system to robots. Over the … Weiterlesen …

For quite some time, scientists have been promoting hydrogen as the energy source of the future, with applications in mobility and as a replacement of fossil fuels, e.g., for heating or for the chemical industry. Now it has found additional … Weiterlesen …

The production of steel is particularly CO2 intensive. To convert iron ore into steel, manufacturers must separate the oxygen bound in the ore from the iron using carbon, i.e. coke, to do this. In the blast furnace, oxygen forms carbon monoxide … Weiterlesen …
