Platelets instead of spheres make screens more economical

23-Jan-2020

ETH scientists have further developed QLED technology for screens. They have produced light sources that for the first time emit high-​intensity light in only one direction. This reduces scattering losses, which makes the technology extremely energy efficient. QLED screens have been on the market ...

New computational screening approach identifies potential solid-state electrolytes

20-Jan-2020

Replacing the volatile and flammable liquid or polymer electrolytes now used in lithium-ion batteries with inorganic solid-state lithium-ionic ceramic conductors could significantly improve both safety and performance of the cells. Solid-state conductors would allow for novel cathode and anode ...

Visualizing chemical reactions

On the way to synthetic fuels

10-Jan-2020

Researchers at the joint EPFL-Empa lab in Sion have developed a reactor system and an analysis method that has allowed them to observe the real-time production of synthetic natural gas from CO2 and H2 for the first time. Infrared (IR) thermography is used to determine the temperature of humans ...

2D materials: arrangement of atoms measured in silicene

03-Jan-2020

Silicene consists of a single layer of silicon atoms. In contrast to the ultra-flat material graphene, which is made of carbon, silicene shows surface irregularities that influence its electronic properties. Now, physicists from the University of Basel have been able to precisely determine this ...

Honey, I shrunk Michelangelo's David

Researchers in Zurich have reproduced Michelangelo’s David as a miniature in metal

02-Jan-2020

There he is, standing upon his pedestal: David by Michelangelo. A world-​famous statue that nearly every child can recognise. But this David is just 1 millimeter tall, pedestal included, and is made not of marble like the 5.17-​meter original, but of pure copper. It was created using 3D printing ...

The power inside

20-Dec-2019

Metamaterials defy conventions, making rigid media flexible, soft materials transmit signals, and sound and light behave in bizarre ways. Metamaterials are engineered to possess properties not found in nature. The ceramic cube under the microscope is gifted with superpowers. Compressed to nearly ...
