Researchers create a new conductive composite from graphene 'foam'

Researchers from the Chinese Academy of Sciences' Institute of Metal Research developed a way to turn graphene into porous three-dimensional 'foam' using chemical vapor deposition (CVD). This 'foam' has extremely high conductivity and when permeated with a siloxane-based polymer it results in a composite that can be twisted, stretched and bent without harming its electrical or mechanical properties.

This foam has a unique network structure, large surface area, very low density and outstanding electrical and mechanical properties. This can find uses in many fields- flexible electronics, fuel cell electrodes, biomedical supports and more.

Researchers created graphene quantum dots from C60 fullerene

Researchers from the National University of Singapore (NUS) and A*STAR developed a new method to create Quantum Dots from Graphene. The idea is to start with a C60 fullerene (a soccer ball like spherical carbon structure that costs of 60 carbon atoms) and 'open' them up (or decompose them) at high temperature using ruthenium as a catalyst.

The researcher performed the decomposition using a sparser coverage of fullerenes on the catalytic ruthenium surface than previously tried - which gave the fullerenes room to prevent carbon atoms from diffusing from one fullerene to the next.

Angstron Supercapacitor, spun-off from Angstron Materials, to produce graphene based supercapacitor electrode material made from Graphene

Angstron Materials announced a spin-off company called Angstron Supercapacitor that was formed to produce a new supercapacitor electrode material made from Graphene.

The new material (patented by US patent #7,623,340) is based on nano graphene platelets (NGPs). Angstron developed curved graphene sheets that resist restacking and this dramatically improved surface area and energy density.

Research proposes a two-dimensional metamaterials that could be achieved by controlling the conductivity of sheets of graphene

Researchers from the University of Pennsylvania have published a theoretical paper that proposed the possibility of two-dimensional metamaterials that could be achieved by controlling the conductivity of sheets of graphene

The research shows that transformation optics (manipulating electromagnetic, or acoustic waves) can be achieved using a single sheet of graphene. This could lead to applications in a lot of fields such as telecommunication and image or signal processing.

IBM developed a 10Ghz graphene IC

IBM developed a 10 Ghz integrated circuit (IC) made from Graphene. This research proved that graphene can be fabricated on a wafer - similar to silicon chips and graphene transistors can be bonded with components from other materials.

According to IBM, there are big advantages in using graphene in analog components, and that's where IBM is focusing its work. IBM already developed a 100Ghz graphene transistor and plans to develop a 1Thz one. In a different research, IBM developed a graphene transistor with a record cut-off frequency of 155 Ghz and the shortest gate length ever .

Researchers developed a new mechanism for gap opening in strained graphene

Researchers from the IBM TJ Watson Research Center and the Universities of Madrid and Nijmegen developed a new mechanism for gap opening in strained graphene via electrostatic gates. The new method also have real applications.

The researchers say that when the pseudomagnetic fields created by long-wavelength deformations are appropriately coupled with an electric scalar potential, a significant gap can emerge due to the formation of a Haldane state. At present, all known ways of gap opening in graphene have a detrimental effect on the electron mobility.
