Simple electric fields unleash autonomous liquid droplet propulsion

Mar 05, 2024 (Nanowerk Spotlight) Scientists have long sought ways to propel tiny liquid droplets autonomously, envisioning applications like miniaturized delivery vehicles or microrobotic systems. However, previous methods faced major limitations - they required specialized materials, continuous energy inputs, or could not control the direction and reversibility of motion. Now,...

Open quantum system shows universal behavior

Mar 05, 2024 (Nanowerk News) Phase transitions in chemistry and physics are changes in the state of a substance, for example the change from a liquid to a gaseous phase, when an external parameter such as temperature or pressure is changed. "Magnets are a good example," says Professor Dr. Artur...

Like a lab in your pocket

Mar 05, 2024 (Nanowerk News) When the pandemic started, people who felt unwell had to join long queues for lab-based PCR tests and then wait for two days to learn if they had the COVID-19 virus or not. In addition to significant inconvenience, a major drawback was the substantial and...
