Scientists have generated a huge true random number using DNA synthesis: It is the first time that a number of this magnitude has been created by biochemical means.
True random numbers are required in fields as diverse as slot machines and data encryption. These numbers need to be truly random, such that they cannot even be predicted by people with detailed knowledge of the method used to generate them. As a rule, they are generated using physical methods. ...
Good catalytic performance is driven chiefly by processes that occur on the surface of the catalyst – and not electrochemical processes
Splitting water into hydrogen and oxygen is an important chemical reaction, especially considering that the use of hydrogen as an energy source in sustainable mobility in the future. An international research team has now decoded how one of the catalysts used in this reaction works. Hydrogen is a ...
Luminescent and hydrophobic wood films as optical lighting materials
The right indoor lighting can help set the mood, from a soft romantic glow to bright, stimulating colors. But some materials used for lighting, such as plastics, are not eco-friendly. Now, researchers reporting in ACS Nano have developed a bio-based, luminescent, water-resistant wood film that ...
Innovative bio-propellant from gas and water
Biodegradable plastics are very much on trend. But there are still very few sustainable alternatives for products containing foamed plastic. ETH Pioneer Fellow Zuzana Sediva is developing a process that could one day be used to make shoe soles and yoga mats from organic waste. Zuzana Sediva loves ...
Ready-to-wear solar cells
Empa researchers succeeded in developing a material that works like a luminescent solar concentrator and can even be applied to textiles. This opens up numerous possibilities for producing energy directly where it is needed, i.e. in the use of everyday electronics. Our hunger for energy is ...
ETH spin-offs are much more likely to make an exit than other Swiss start-ups
As well as generating more jobs on average than other Swiss start-ups, ETH spin-offsare also acquired more frequently. A decisive factor, according to University of St.Gallen’s comprehensive analysis, comes from the institutional support for entrepreneurship. With around 500 ETH spin-offs now ...
Membrane massively reduces volumes of waste
The nuclear accident in Fukushima remains etched into people's memories. It was a catastrophe that caused huge amounts of radioactively contaminated water to be released, which the operators of the nuclear power plant subsequently had to clean up. One of the methods they used was reverse osmosis ...
For the first time, researchers have managed to create and identify antiferromagnetic skyrmions with a unique property
Nanoscale vortices known as skyrmions can be created in many magnetic materials. For the first time, researchers at PSI have managed to create and identify antiferromagnetic skyrmions with a unique property: critical elements inside them are arranged in opposing directions. Scientists have ...
Get zeolite research out of the dead end
Researchers at the Paul Scherrer Institute PSI and from ETH Zurich want to make so-called zeolites more efficient. Today, these compounds are already indispensable additives in the chemical industry and have been used as catalysts in oil refineries since the 1960s. Now, in the journal Nature ...
A new revolution in the production of electronic circuits is on the way
Empa researchers are working on electronics that come out of printers. This makes it possible to produce the circuits on all sorts of substrates, such as paper or plastic film – but there are still some hurdles to overcome. Imagine being able to easily print electronics on any surface. Today, ...
