Active boundary heating and cooling can make a small object look much larger to thermal sensors, a step toward compact thermal camouflage and new ways to steer heat in devices. (Nanowerk Spotlight) ...

In a new study, researchers at CU Boulder have used doughnut-shaped beams of light to take detailed images of objects too tiny to view with traditional microscopes. The new technique could help ...

The future of imaging extremely small objects may come down to doughnut-shaped beams of light, according to a study from researchers at JILA and the Department of Physics. The study explored the ...
