Samples of the new ceramic aerogel, which is incredibly lightweight and can withstand intense heat fluctuations(Credit: Oszie Tarula/UCLA)Ceramic aerogels have been protecting industrial equipment and space-bound scientific instruments for decades, thanks to their incredible lightness and ability to withstand intense heat. The problem is they can be pretty brittle. Now, a team led by researchers at the University of California Los Angeles (UCLA) has developed a new ceramic aerogel that's far hardier and more flexible, even after repeated exposure to wild temperature swings.Aerogels are strong, solid structures that are up to 99 percent air by volume, which of course makes them incredibly lightweight. They can be made of many different types of materials, but ceramics are particul...

The era of electromobility presents new challenges which must be mastered by both man and materials. Today, neodymium-iron-boron-magnets are used in areas in which strong magnetic fields at low volumes and low weights are necessary. These so-called rare earth magnets guarantee the resource conservation of raw materials, weight reduction of the drives and longer service lives required of permanent magnets. However, they are more complicated to manufacture than conventional magnets. A decisive factor for the quality and properties of permanent magnets is a raw material with a narrow particle size distribution with the lowest possible fraction of finest- ( 8 µm).

3D printing and other additive production techniques make it possible to manufacture materials with internal structures of previously unimaginable complexity. This is interesting for lightweight construction, too, as it enables the development of materials that have the highest possible share of interior voids (to make the materials as light as possible) but are simultaneously as robust as possible. Achieving this requires that the internal structures be intelligently organised for maximum efficiency.
