Rice University discovers that graphene oxide soaks up radioactive waste

(Rice University) Graphene oxide has a remarkable ability to quickly remove radioactive material from contaminated water, researchers at Rice University and Lomonosov Moscow State University have foun...

New research gives insight into graphene grain boundaries

Using graphene either as an alternative to, or most likely as a complementary material with silicon, offers the promise of much faster future electronics, along with several other advantages over th...

Graphene nanopores can be controlled: Less costly ways of sequencing DNA

Engineers have used advanced techniques to make the material graphene small enough to read DNA. Shrinking the size of a graphene pore to less than one nanometer opens the possibility of graphene as a...

Engineers at the University of Texas at Dallas have used advanced techniques to make the material graphene small enough to read DNA. Shrinking the size of a graphene pore to less than one nanometer, s...

Research gives insight into graphene-metal junctions

The next step in building graphene-based electronic devices requires creating junctions that connect graphene to the external world through at least two metal wires. A two-terminal junction is a graph...

Combined optical technique gives answers on graphene

In a successful effort to analyze a graphene-insulator-semiconductor structure, scientists at NIST’s Physical Measurement Laboratory developed a combined optical technique that uses both internal...

First principles calculations of the electronic and chemical properties of graphene, graphane, and graphene oxide.

The electrical and chemical properties of graphene (C(24)H(12)), graphane (C(24)H(24)) and graphene oxide (C(54)H(17)+O+(OH)(3)+COOH) were studied through the density functional theory (DFT) at level...

Terahertz photonic states in semiconductor-graphene cylinder structures.

We propose a semiconductor-graphene cylinder that can serve as a terahertz (THz) photonic crystal. In such a structure, graphene plays a role in achieving a strong mismatch of the dielectric constant...

Dual n-type doped reduced graphene oxide field effect transistors controlled by semiconductor nanocrystals.

Here, we demonstrate a rapid and simple method for doping a reduced graphene oxide (rGO) field effect transistor (FET) with nanocrystals to produce dual n-type behavior with light and bias voltage. Th...

n-Type Reduced Graphene Oxide Field-Effect Transistors (FETs) from Photoactive Metal Oxides.

Graphene is of considerable interest as a next-generation semiconductor material to serve as a possible substitute for silicon. For real device applications with complete circuits, effective n-type gr...

Temperature-dependent electrical property transition of graphene oxide paper.

Reduction of graphene oxide is primarily important because different reduction methods may result in graphene with totally different properties. For systematically exploring the reduction of graphene...
