The random raman laser: A new light source for the microcosmos

In modern microscope imaging techniques, lasers are used as light sources because they can deliver fast pulsed and extremely high-intensity radiation to a target, allowing for rapid image acquisition. However, traditional lasers come with a significant disadvantage in that they produce images with blurred speckle patterns -- a visual artifact that...

Many uses in researching quantum dots

It's easier to dissolve a sugar cube in a glass of water by crushing the cube first, because the numerous tiny particles cover more surface area in the water than the cube itself. In a way, the same principle applies to the potential value of materials composed of nanoparticles. Ari Chakraborty is an assistant professor of chemistry at Syracuse University....

From brittle to plastic in one breath

What if peanut brittle, under certain conditions, behaved like taffy? Something like that happens to a two-dimensional dichalcogenide analyzed by scientists at Rice University. Rice researchers calculated that atomically thin layers of molybdenum disulfide can take on the qualities of plastic through exposure to a sulfur-infused gas at the right temperature...
