Paper-thin optical lenses have a bright future

Jan 16, 2025 (Nanowerk News) Paper-thin optical lenses simple enough to mass produce like microchips could enable a new generation of compact optical devices. A team with researchers at the University of Tokyo and JSR Corp. fabricated and tested flat lenses called Fresnel zone plates (FZPs), but did so for...

Watching the oscillations of an electron sea

Jan 16, 2025 (Nanowerk News) Imagine standing by a lake and throwing a stone into the water. Waves spread out in circular patterns and can reflect at obstacles and boundaries. Researchers at the University of Regensburg, in collaboration with colleagues from Milan and Pisa, have recreated this everyday phenomenon in...

Scientists create tiny motors that mimic nature

Jan 16, 2025 (Nanowerk News) Scientists have built an artificial motor capable of mimicking the natural mechanisms that power life. Just like the proteins in our muscles, which convert chemical energy into power to allow us to perform daily tasks, these tiny rotary motors use chemical energy to generate force,...
