Novel materials: Sound waves traveling backward

Acoustic waves in gases, liquids, and solids usually travel at an almost constant speed of sound. So-called rotons are an exception: their speed of sound changes significantly with the wavelength, and it is also possible ...

Machine learning speeds up simulations in material science

Research, development, and production of novel materials depend heavily on the availability of fast and at the same time accurate simulation methods. Machine learning, in which artificial intelligence (AI) autonomously acquires ...

Comprehensive electronic-structure methods for materials design

Nicola Marzari, head of the Theory and Simulation of Materials laboratory at EFPL and director of NCCR MARVEL, has just published a review of electronic-structure methods as part of a special edition Insight on Computational ...

Order up! AI finds the right material

Engineers are always looking for materials with very specific properties for their projects. Unfortunately, there are way too many options for researchers to simply guess-and-check until they find what they're looking for. ...

The key to lowering carbon dioxide emissions is made of metal

Carbon dioxide (CO2) levels are rising and our planet is heating up. What do we do? What if we used this excess CO2 as a raw material to produce things we need—similar to how plants use it to produce oxygen.
