Farewell to the “queen of carbon science”

The material science community says farewell to a legend – Mildred Dresselhaus, Professor Emerita at MIT, died at the age of 86. Nicknamed “the queen of carbon science”, prof. Dresselhaus studied various aspects of graphite, including nanomaterials such as graphene, carbon nanotubes, and fullerene. She made some fundamental discoveries on...

Record high frequency RF graphene transistors on flexible substrates

Graphene has long been regarded as an ideal candidate channel material for radio frequency (RF) flexible electronics. Scientists from IEMN-CNRS, Graphenea, and Nokia have now demonstrated flexible graphene transistors with a record high cut-off frequency of 39 GHz. The graphene devices, made on flexible polymer substrates, are stable against bending...

Stable and consistent graphene electronic devices

Researchers have developed a stable platform for manufacturing electronic devices made of graphene. Graphene field effect transistors (GFETs) made with this platform are shown to be stable against atmospheric influences and uniform in their properties across a batch of more than 500 devices.

Utilizing 2D crystals in methanol fuel cells

Fuel cells are a technology of interest as future energy sources, as they aid in production of sustainable energy using simple hydrocarbons as fuels. They function by a simple operational mechanism with fuel oxidation on one side, and oxidant reduction on the other side of a membrane, liberating electrons thus...
