In recent years, scientists have been studying special materials called topological materials, with special attention paid to the shape, i.e., topology, of their electronic structures (electronic bands). Although it is not visible in real space, their unusual shape in topological materials produces various unique properties that can be suitable for making next-generation devices.

Read moreThe main characteristic of Spark Plasma Sintering (SPS) is that the pulsed or unpulsed DC or AC current directly passes through the graphite die as well as the powder compact, in case of conductive samples.
Read moreAlloys that can return to their original structure after being deformed have a so-called shape memory. This phenomenon and the resulting forces are used in many mechanical actuating systems, for example in generators or hydraulic pumps. However, it has not been possible to use this shape-memory effect at a small nanoscale: Objects made of shape-memory alloy can only change back to their original shape if they are larger than around 50 nanometers.

Although most people can’t do math as fast as a computer, we can effortlessly process complex sensory information and learn from experiences, while a computer cannot – at least not yet. And, the brain does all this by consuming less than half as much energy as a laptop.
