Tsunami in a water glass

“A new experiment has made it possible to observe the effects of an electron in solution on the surrounding liquid. So-called hydrated electrons play a major role in many physical, chemical and biological processes. They are not bound to an …

Cubes outperform spheres as catalyst particles

“The shape of nanoparticles is a decisive factor in their efficiency as catalysts for the production of green hydrogen. To date, nanoparticles as catalysts for green hydrogen have been like rowers in an eight: researchers could only measure their average …

Laser controls ultra-fast water switch

“Researchers present a completely new concept for switches with unprecedented speed. Researchers at Ruhr-Universität Bochum have developed an ultra-fast circuit based on water. With a short but strong laser pulse, the water can be put into a conductive state within …

3D printed surfaces inspired by nature

“Scientists can use laser radiation to print tiny structures with high precision. This approach enables them to mimic the superpowers of animals and plants and makes them accessible for engineering applications. To survive in extreme habitats, many animals and plants …

Radio waves for the detection of hardware tampering

“Up to now, protecting hardware against manipulation has been a laborious business: expensive, and only possible on a small scale. And yet, two simple antennas might do the trick. As far as data security is concerned, there is an even …

Molecular machine in nano cage

“What a toy: a tiny gyroscope that would fit in a human cell and that can be controlled from the outside. In cooperation with an international team at the Institute for Basic Science in South Korea, theoretical chemists Dr. Chandan …

A seemingly unattainable energy transition

“Researchers have managed to address an unusual energy transition in a semiconductor. Researchers from Basel and Bochum have succeeded in addressing an apparently unattainable energy transition in an artificial atom using laser light. Making use of the so-called radiative Auger …

How positively and negatively charged ions behave at interfaces

“When charged particles enter the boundary layer between a liquid and an electrode, they first have to strip off their water shells. How positively and negatively charged ions behave at the interface between a solid surface and an aqueous solution …

How cola still tingles after a year

“A few nanometers of thin quartz-like coatings can multiply the shelf life of food, enable brilliant OLED TV pictures or separate gases from each other. When it comes to recycling, they can simply be neglected. When you add energy to …

Challenges in the development of electrocatalysts

“Efficient catalysts are crucial for energy conversion. However, findings from basic research rarely make it into practice at present. Regenerative energy harvesting often generates more electricity than is directly needed. Electrochemical processes could be used to store the excess energy …
