Graphene gets bright: World's thinnest lightbulb developed

Led by Young Duck Kim, a postdoctoral research scientist in James Hone's group at Columbia Engineering, a team of scientists from Columbia, Seoul National University (SNU), and Korea Research Institute of Standards and Science ...

Two-dimensional material seems to disappear, but doesn't

(Phys.org)—When exposed to air, a luminescent 2D material called molybdenum telluride (MoTe2) appears to decompose within a couple days, losing its optical contrast and becoming virtually transparent. But when scientists ...

New 'designer carbon' boosts battery performance

Stanford University scientists have created a new carbon material that significantly boosts the performance of energy-storage technologies. Their results are featured on the cover of the journal ACS Central Science.

Tiny wires could provide a big energy boost

Wearable electronic devices for health and fitness monitoring are a rapidly growing area of consumer electronics; one of their biggest limitations is the capacity of their tiny batteries to deliver enough power to transmit ...

Graphene sheets enable ultrasound transmitters

University of California, Berkeley, physicists have used graphene to build lightweight ultrasonic loudspeakers and microphones, enabling people to mimic bats or dolphins' ability to use sound to communicate and gauge the ...

Polymer mold makes perfect silicon nanostructures

Using molds to shape things is as old as humanity. In the Bronze Age, the copper-tin alloy was melted and cast into weapons in ceramic molds. Today, injection and extrusion molding shape hot liquids into everything from car ...

How to make continuous rolls of graphene

Graphene is a material with a host of potential applications, including in flexible light sources, solar panels that could be integrated into windows, and membranes to desalinate and purify water. But all these possible uses ...

Simulations lead to design of near-frictionless material

Argonne scientists used Mira to identify and improve a new mechanism for eliminating friction, which fed into the development of a hybrid material that exhibited superlubricity at the macroscale for the first time. Argonne ...
