An 18-carat gold nugget made of plastic

14-Jan-2020

ETH researchers have created an incredibly lightweight 18-​carat gold, using a matrix of plastic in place of metallic alloy elements. Lovers of gold watches and heavy jewellery will be thrilled. The objects of their desire may someday become much lighter, but without losing any of their glitter. ...

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 ...

Glass from a 3D printer

27-Nov-2019

ETH researchers used a 3D printing process to produce complex and highly porous glass objects. The basis for this is a special resin that can be cured with UV light. Producing glass objects using 3D printing is not easy. Only a few groups of researchers around the world have attempted to produce ...

Observing changes in the chirality of molecules in real time

19-Nov-2019

Chiral molecules - compounds that are mirror images of each other - play an important role in biological processes and in chemical synthesis. Chemists at ETH Zurich have now succeeded for the first time in using ultrafast laser pulses to observe changes in chirality during a chemical reaction in ...

Monitoring the corrosion of bioresorbable magnesium

Better prediction of degradation rate of magnesium implants

28-Oct-2019

ETH researchers have recently been able to monitor the corrosion of bioresorbable magnesium alloys at the nanoscale over a time scale of a few seconds to many hours. This is an important step towards accurately predicting how fast implants are resorbed by the body to enable the development of ...

Using industrial waste as insulation for buildings

15-Oct-2019

ETH spinoff FenX transforms industrial waste into a porous foam suitable for building insulation. Unlike other sustainable materials used for the purpose, this type of insulation is non-flammable and inexpensive to produce. No sooner does one of the four young men come up with the idea than they ...

Deep learning, prefabricated

09-Oct-2019

Self-driving cars, the automatic detection of cancer cells, online translation: deep learning makes it all possible. The ETH spin-off Mirage Technologies has developed a deep learning platform that aims to help start-ups and companies more quickly develop and optimise their products. The name has ...

Mini-spectrometer: Smaller than a coin

09-Oct-2019

ETH researchers have developed a compact infrared spectrometer. It’s small enough to fit on a computer chip but can still open up interesting possibilities – in space and in everyday life. Nowadays, a mobile phone can do almost anything: take photos or video, send messages, determine its present ...

A battery with a twist

25-Sep-2019

Markus Niederberger’s team of researchers at ETH has used stretchable materials to develop a battery that can be bent, stretched and twisted. For applications in bendable electronic devices, this is precisely the kind of battery they need. Today’s electronics industry is increasingly focusing on ...
