Saint Jean Carbon achieves magnetoresistance graphene

Saint Jean Carbon, a carbon science company engaged in the exploration of natural graphite properties and related carbon products, has teamed up with the University of Western Ontario to create graphene that has a magnetic field (Magnetoresistance).

One of the involved researchers explained that: "Magnetoresistance (MR) refers to the significant change of electrical resistance of materials under a magnetic field. Magnetoresistance effects have been applied in magnetic sensors, spintronic devices and data storage. Magnetic sensors are extremely useful for today's industry for measurement and control purposes... This happens by detecting changes in electrical resistance brought on by the presence of a magnetic field. This is also known as magnetoresistance (MR). The market size of the magnetic sensor is increasing with annual growth rate at 10% because of new nanomaterials..."

Graphene-pophyrin hybrid to enable new possibilities in sensors, electronics and more

Researchers at the Technical University of Munich (TUM) have succeeded in linking graphene with a chemical group called porphyrins, which are well-known because of their notable functional properties (for instance, playing a central role in chlorophyll during photosynthesis). These new hybrid structures could be used in the field of molecular electronics, catalysis or even as sensors.

Many researchers focus on wet-chemical methods for attaching the molecules to the surface of the material. The TUM team, however, decided to take a different approach: The researchers were able to link porphyrin molecules to graphene in a controlled manner in an ultra-high vacuum using the catalytic properties of a silver surface on which the graphene layer rested. When heated, the porphyrin molecules lose hydrogen atoms at their periphery and can thus form new bonds with the graphene edges.

NanoXplore to partner with SDTC on graphene-enhanced components for electric motor systems

NanoXplore logoGroup NanoXplore, a Canadian company specializing in the production and application of graphene and its derivative materials, has announced that Sustainable Development Technology Canada (SDTC) will partner with the company to support the commercialization of lighter, more reliable and higher-efficiency components for electric motor systems using graphene-enhanced engineering plastics in place of metals. The total value of the project is $10.4 million.

Replacing metals with plastics will require innovative polymers with unique thermal, electrical, and strength characteristics. NanoXplore has developed and is providing customers with graphene-enhanced polymers with enhanced electrical, thermal and mechanical properties. By adding trace amounts of graphene to carefully-selected polymers, engineering plastics can be tailored to improve electric motors and the systems they are used in.

Lomiko to present graphene supercapacitor prototype at Battery Materials Conference in Toronto

Lomiko Metals has announced that it will be presenting a summary of the Graphene Energy Storage Devices Corp. (GESD) Graphene Supercapacitor Project at the Battery Material Conference in Toronto September 2016.

GESD is currently working on scale-up of the technology and an in-field evaluation of the energy storage unit with Stony Brook University. The GESD-SBU team demonstrated design and implementation of a sealed high-voltage EDLCs energy storage unit. The unit is internally balanced, there is no need for an external circuit. The electrode is very cost-effective nano-carbon composite either of a commercial carbon or of graphene platelets with carbon nanotubes. The nano-carbon electrode materials were used for deposition and assembly of a working prototype of an internally balanced high-voltage energy storage unit. The bench-top prototype unit, tested up to 10 V, exhibited good discharge characteristics and charge retention. This development enables new compact energy storage solutions for grid and vehicular applications.

Graphene nanoribbons may prove helpful for treating spinal injuries

Researchers at Rice University have shown that combining graphene nanoribbons, made with a process developed at Rice University, and a common polymer to create a material called Texas-PEG could have potential of aiding in treating damaged spinal cords in people.

The customized GNRs are highly soluble in polyethylene glycol (PEG), a biocompatible polymer gel used in surgeries, pharmaceutical products and in other biological applications. When the biocompatible nanoribbons have their edges functionalized with PEG chains and are then further mixed with PEG, they form an electrically active network that can help the severed ends of a spinal cord reconnect (neurons tend to grow on graphene because it’s a conductive surface).

Graphene 3D Lab to raise $500,000 in a private placement

Graphene 3D Labs logoGraphene 3D Lab announced it is set to raise $500,000 USD in a new private placement of shares and warrants. This follows the company $600,000 private placement done in July 2016.

In April 2016, Graphene 3D Lab announced that it has been approved to move forward with the next task of its research, development and royalty agreement with a Fortune 500 listed manufacturer. In May 2016, Graphene 3D Lab announced its financial results for Q1 2016. Revenues increased to $265,271 - up 354% from last quarter's revenues of $58,369.

Zenyatta and Larisplast enter phase 2 of agreement to develop graphene-enhanced concrete admixture

Zenyatta logoZenyatta Ventures recently announced that it has signed a collaboration agreement with Larisplast, an Israeli business that specializes in the field of concrete admixtures. Zenyatta and Larisplast have both received grant funding from the Canada-Israel Industrial R&D Foundation under the Ontario-Israel Collaboration Program to further test the effect of adding graphene generated from Zenyatta’s Albany graphite to concrete on a pilot scale. Now, after a successful phase 1, the companies announce the beginning of phase 2.

Upon successful completion of pilot plant testing, the agreement contemplates the formation of a new corporation ('Newco') jointly owned (50/50) by Zenyatta and Larisplast for the purposes of marketing this new specialized admixture product globally. Zenyatta would be the exclusive provider of purified graphite to Newco and any other party working with Larisplast on this technology.

Graphene, GO and rGO grown onto silicon chips could pave way to biosensors and electronics

Researchers at North Carolina State University have developed a technique that enables the integration of graphene, graphene oxide (GO) and reduced graphene oxide (rGO) onto silicon substrates at room temperature by using nanosecond pulsed laser annealing. The advance may open the door to the possibility of creating new electronic devices, such as smart biomedical sensors.

In this new technique, the researchers start with a silicon substrate. They top that with a layer of single-crystal titanium nitride, using domain matching epitaxy to ensure the crystalline structure of the titanium nitride is aligned with the structure of the silicon. They then place a layer of copper-carbon alloy on top of the titanium nitride, again using domain matching epitaxy. Finally, the researchers melt the surface of the alloy with nanosecond laser pulses, which pulls carbon to the surface.
