Researchers from Bilkent University in Turkey developed a new display prototype that is based on a graphene ink deposited on a regular paper. The paper display has high optical contrast and a fast response time. Such a paper-like display can be very flexible and foldable.

To create this display, the researchers used electro-modulation of the optical properties of the multilayer graphene via blocking the interband electronic transitions.

Zenyatta Ventures recently announced receiving grant funding from the Canada‐Israel Industrial R&D Foundation (CIIRDF) for the Production of Nano‐Graphite‐Reinforced Cement Admixture under the Ontario‐Israel Collaboration Program (OICP).

Zenyatta, Larisplast, Ben‐Gurion University of the Negev (BGU) and B.G. Negev Technologies (BGN) recently signed a Memorandum of Understanding while on the Ontario Business Mission to Israel. Each partner will have a unique technical contribution in a scaled up program from the successful bench scale testing. This new program will have subtotal costs of $207,002 CAD (Zenyatta) and $322,129 CAD (Larisplast) for a total of $529,131 CAD of which 50% will be refunded under this OICP grant.

A team of scientists at the U.S. Naval Research Laboratory (NRL) has demonstrated hyperthermal ion implantation (HyTII) as an effective means of doping graphene with nitrogen atoms. The result is a low-defect film with a tunable bandstructure that could be useful in a variety of device platforms and applications.

According to the research, the HyTII method delivers a high degree of control including doping concentration and, for the first time, demonstrates depth control of implantation by doping a single monolayer of graphene in a bilayer graphene stack. This further demonstrates that the resulting films have high-quality electronic transport properties that can be described solely by changes in bandstructure rather than the defect-dominated behavior of graphene films doped or functionalized using other methods.

The Graphene Flagship includes a Spintronics Work Package - the aims to explore graphene's role in spintronics. Last week the participants in this initiative met for the first time in an event organised by the Deputy Leader of the Spintronics Work Package, and hopefully these interesting projects will bear fruit soon.

Researchers at A*STAR have found that graphene could be helpful in improving the performance of computer hard drives.

Hard drives store data by using magnetic fields to change the properties of a small section of a magnetically sensitive material. Decreasing the size of this section increases the drive’s capacity but also increases the size of the magnetic field required for switching. Furthermore, the minimum size of the magnetic field is limited by an effect known as superparamagnetism, in which the magnetic properties at the nanometer-scale can spontaneously change, losing any stored information. HAMR (heat-assisted magnetic recording) is a method that uses a laser beam to heat the storage medium to a temperature at which the magnetic field strength required for writing is lower and superparamagnetism is less prevalent.

In March 2016 we posted that Pacific American Coal (PAK) will take a controlling interest in Imagine Intelligent Materials, the Australian developer of graphene-based coatings for industrial textiles and fibers.

PAK announced that the company has now completed the acquisition of a 20% stake in Imagine IM. PAK raised $1.6 million (before costs) which will be used to fund the first phase of the Imagine acquisition. PAK is scheduled to acquire another 20% from Imagine IM’s existing shareholders by 30th June 2016.

Researchers from Korea's KAIST institute developed a rollable OLED device that uses graphene-based electrodes. The researchers say that the new OLED is much more durable when bent compared to current devices made with ITO electrodes.

The electrodes were made from a stack of materials - titanium oxdies, graphene and conductive polymers. The new OLEDs were also brighter than current devices, and with a higher color gamut. This was achieved by maximizing the resonance within the OLED.

Researchers at the University of Central Florida (UCF) have been awarded $1.3 million by the Defense Advanced Research Projects Agency to develop graphene-based next-generation infrared detectors. The award will fund the team's research for the next 3.5 years.

The detector could potentially be used for night vision, meteorology and even space exploration. It is based on a novel infrared detection and imaging technology that is said to be very different than what is being currently used, since most portable infrared cameras (such as those used by police and firefighters) produce extremely blurry images. Other, more powerful infrared detectors (such as the ones used by NASA) are extremely large, expensive and only operate in low temperatures. The main obstacle is that most infrared detectors need cryogenic cooling, which is large and hard to handle.
