Stable Catalysts for New Energy

Crucial new technologies such as hydrogen production or carbon capture require new catalysts. Experiments show: It's not just the material that matters, but also its atomic surface structure

26-Nov-2020

On the way to a CO2-neutral economy, we need to perfect a whole range of technologies - including the electrochemical extraction of hydrogen from water, fuel cells, or carbon capture. All these technologies have one thing in common: they only work if suitable catalysts are used. For many years, ...

Animal-free method predicts nanoparticle toxicity for safer industrial materials

A step closer to safe-by-design material development

26-Nov-2020

Researchers at Helmholtz Zentrum München together with scientists across Europe developed a novel animal-free method to predict the toxic effect of nanoparticles to the human lung. The method aims to enable the safety-by-design development of safer industrial materials. Our lungs are exposed to a ...

Controlling fully integrated nanodiamonds

Physicists integrate diamond-based quantum systems into nanophotonic circuits

25-Nov-2020

Using modern nanotechnology, it is possible nowadays to produce structures which have a feature sizes of just a few nanometres. This world of the most minute particles – also known as quantum systems – makes possible a wide range of technological applications, in fields which include magnetic ...

Researchers prove water has multiple liquid states

A newly published Science journal paper reveals that water can exist as two liquids of differing density

25-Nov-2020

Water is a ubiquitous liquid with many highly unique properties. The way it responds to changes in pressure and temperature can be completely different from other liquids that we know, and these properties are essential to many practical applications and particularly to life as we know it. What ...

New test to better assess environmental impact of substances

Researchers developed a test that investigates whether substances can cause inheritable changes in the genome of multicellular organisms such as insects

24-Nov-2020

Researchers of the Senckenberg Biodiversity and Climate Research Centre and the LOEWE Centre for Translational Biodiversity Genomics hope to increase the reliability of environmental impact tests of substances. To this end, they developed a test that investigates whether substances can cause ...

Topology Gets Magnetic: The New Wave Of Topological Magnetic Materials

Researchers demonstrate new high-throughput method for discovering magnetic topology

24-Nov-2020

The electronic structure of nonmagnetic crystals can be classified by complete theories of band topology, reminiscent of a “topological periodic table.” However, such a classification for magnetic materials has so far been elusive, and hence very few magnetic topological materials have been ...

Molecular telegraphy

Precisely sending and receiving single molecules

23-Nov-2020

Researchers of the University of Graz, Austria, managed to send single molecules to a distant location and receive them from there. The study appears as the cover story in the current issue of the magazine Science. The idea of throwing and catching a ball is familiar to everyone. Now, if the ball ...

Green hydrogen: buoyancy-driven convection in the electrolyte

For the first time investigated, how the liquid electrolyte throughout the cell behaves during electrolysis

23-Nov-2020

Hydrogen produced by using solar energy could contribute to a climate neutral energy system of the future. But there are hurdles on the way from laboratory scale to large-scale implementation. A team at HZB has now presented a method to visualise convection in the electrolyte and to reliably ...

A biochemical random number

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.

23-Nov-2020

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. ...
