Cherned up to the maximum
Cherned up to the maximum
Topological materials are a new class of materials that could enable completely new types of electronic components and superconductors. In topological materials, electrons can behave differently than in conventional materials. The extent of these "exotic" phenomena depends on the so-called Chern number.

To engineers’ surprise, radiation can slow corrosion of some materials
In certain alloys, exposure to proton irradiation can extend the material's lifetime, study finds. Radiation nearly always degrades the materials exposed to it, hastening their deterioration and requiring replacement of key components in high-radiation environments such as nuclear reactors.

Outsmarting self-organization
Outsmarting self-organization
Researchers at ETH Zurich have coaxed tiny spheres made of polymer gels into forming complex patterns by themselves through a two-step process. Surfaces with tailor-made optical and mechanical properties could be realized in this way. When retiling the bathroom or the terrace using, for instance, square, rectangular or hexagonal tiles, the result will be a simple and regular pattern - assuming one doesn't make any mistakes.

New insights into lithium metal technology
New insights into lithium metal technology
It is one of the key technologies for high-performance batteries of the future: the lithium metal battery (LMB). Designed for instance as solid-state battery with polymer electrolyte, it promises a significantly higher energy density than the currently common lithium-ion battery (LIB). However, it is not yet fully developed for the final commercial breakthrough and is therefore currently used by only a few pilot projects.

The lightest shielding material in the world
The lightest shielding material in the world
Researchers have succeeded in applying aerogels to microelectronics: Aerogels based on cellulose nanofibers can effectively shield electromagnetic radiation over a wide frequency range - and they are unrivalled in terms of weight. Electric motors and electronic devices generate electromagnetic fields that sometimes have to be shielded in order not to affect neighboring electronic components or the transmission of signals.

Laser allows solid-state refrigeration of a semiconductor material
To the general public, lasers heat objects. And generally, that would be correct. But lasers also show promise to do quite the opposite - to cool materials. Lasers that can cool materials could revolutionize fields ranging from bio-imaging to quantum communication. In 2015, University of Washington researchers announced that they can use a laser to cool water and other liquids below room temperature.
