Chemical treatment improves quantum dot lasers

One of the secrets to making tiny laser devices such as opthalmic surgery scalpels work even more efficiently is the use of tiny semiconductor particles, called quantum dots. In new research at Los Alamos National Laboratory's ...

A way to cause graphene to self-fold into 3-D shapes

(Phys.org)—A team of researchers with Johns Hopkins University and MIT has found a way to cause flat sheets of graphene to self-fold into 3-D geometric shapes. In their paper published on the open access site Science Advances, ...

Small scale energy harvesters show large scale impact

The production of nano-scale devices has drastically increased with the rise in technological applications, yet a major drawback to the functionality of nano-sized systems is the need for an equally small energy resource.

Faster imaging at the nano level

Tufts researchers have discovered a new, faster way to image materials at the nano level, an advance that could speed the detection of cancer and assist in the development of new high-tech materials.
