Reducing friction with an onion-like carbon material

Researchers developed a new self-generating lubricant with great potential for industrial applications.

Medical nanorobot enters Guinness World Records

A 120 nanometer long robot is now world record holder in the Guinness World Records for creating the Smallest Medical Robot.

A novel graphene quantum dot structure takes the cake

In a marriage of quantum science and solid-state physics, researchers have used magnetic fields to confine groups of electrons to a series of concentric rings within graphene, a single layer of tightly packed carbon atoms.

Water vapor annealing technique on diamond surfaces for next-generation power devices

The existing surface termination technique using hydrogen to stabilize the diamond's structure for application in electronic power devices results in two-dimensional hole gas layers (2DHG). Attempting to remove these layers using oxygen-termination roughens the diamond surface and leads to degradation of the device performance. To overcome this, researchers have removed 2DHG from diamond using water vapor annealing and maintained an atomically flat surface.

Improved efficiency and stability of quantum dot solar cells using an organic thin film

Researchers have achieved highly stable and efficient colloidal quantum dot-based solar cells by using an amorphous organic layer to block oxygen and water permeation.
