Nanodevices can produce energy from evaporating tap or seawater

Evaporation is a natural process so ubiquitous that most of us take it for granted. In fact, roughly half of the solar energy that reaches the Earth drives evaporative processes. Since 2017, researchers have been working ...

How does a 'reverse sprinkler' work? Researchers solve decades-old physics puzzle

For decades scientists have been trying to solve Feynman's Sprinkler Problem: How does a sprinkler running in reverse—in which the water flows into the device rather than out of it—work? Through a series of experiments, ...

Turning glass into a 'transparent' light-energy harvester

What happens when you expose tellurite glass to femtosecond laser light? That's the question that Gözden Torun at the Galatea Lab at Ecole Polytechnique Federale de Lausanne, in collaboration with Tokyo Tech scientists, ...

Thermoelectric permanent magnet opens new possibilities in thermal management technologies

A research team has demonstrated that the transverse thermoelectric conversion (i.e., energy conversion between charge and heat currents that flow orthogonally to each other) can be greatly enhanced by applying magnetic fields ...

Permselectivity reveals a cool side of nanopores

Researchers from Osaka University investigated the thermal energy changes across nanopores that allow the selective flow of ions. Switching off the flow of ions in one direction led to a cooling effect. The findings have ...

Bowtie resonators that build themselves bridge the gap between nanoscopic and macroscopic

A central goal in quantum optics and photonics is to increase the strength of the interaction between light and matter to produce, for example, better photodetectors or quantum light sources. The best way to do that is to ...
