Indian team develops graphene-based technology for prevention of drunk driving

In April 2018, researchers at the India-based Uttarakhand Residential University, RI Instruments and Innovationin developed a graphene-based technology to prevent vehicles from operating if the driver is drunk. Now, the same team produced a prototype that will be based on graphene generated from waste products and wild grasses as one of the components.

Graphene has an important role in the device as graphene-coated electrodes can catalyze the process of oxidation of ethyl alcohol into acetic acid. The concentration of alcohol will automatically disconnect the device, the team explained. The driver, while at the driving seat, has to blow the graphene sensor on the device to start the vehicle. This will immediately activate the sensor that will analyze and estimate the liquor content present in the blood of the driver.

Global Graphene Group signs LOI with Alison Asia Pacific for graphene-enhanced silicon oxide anode materials

Global Graphene Group (G3) logo imageGlobal Graphene Group (G3) and Alison Asia Pacific recently signed a Letter of Intent (LOI) for business over the next five years. Alison, a Hong Kong-based company, plans to purchase over 300 metric tons of graphene-enhanced silicon oxide anode material from G3.

Alison’s products are widely used in different industries such as energy, environmental protection, sewage treatment, and other fields. G3’s graphene-enhanced silicon oxide anode will support Alison’s rechargeable batteries. G3 will ramp up production of its silicon oxide anode to meet demand.

Zen Graphene Solutions provides updates on its financials and plans

ZEN Graphene Solutions recently shared several updates. The first is that Zen has closed its recent private placement of flow-through common shares of the company and reports that it was oversubscribed. The company raised CAD$1.21 million (around USD$920,300) in respect of the offering, which will be used to finance the 2020 environmental baseline field program and community engagement work on the company's Albany graphite project.

In addition, the Company announced that it is moving forward with graphene production and anticipates that small-scale graphene related production will commence before the end of Q1 2020. The first batch of equipment for the purification small-scale pilot plant was already delivered. In the coming months, ZEN is aiming to setup small-scale graphite purification and graphene-related production facilities including Graphene Quantum Dots (GQDs) and Graphene Oxide (GO). These products will be available for research and development, application development and for commercial use.

Saint Jean Carbon announces two graphene-related projects

Saint Jean Carbon has announced that it has been awarded two graphene-related projects from K-Technology USA.

The first project is the development of superconducting wire based on Saint Jean’s provisional patent application for the development of a diamagnetic superconducting wire. The project intends to develop the necessary engineering to make a prototype wire. The second project is to develop a waste energy capture system patented by K-Technology. The project entails the rewiring of the motors (4) on a drone with Saint Jean hyper-conducting wire and engineering an alternator re capture system to recharge the batteries.

Quantag starts to deploy commercial graphene quantum dots tagging solutions

Turkey-based Quantag Nanotechnologies was established in 2014 as a spin-off from a Turkey-based market-leading petroleum company to develop advanced tagging technologies. The company offers tagging solutions (which it calls Quantum Tagging Technology) based on quantum dots - and is offering complete systems based on its own tags (QDs) and sensors (readers).

Versarien selected for Airbus-backed Graphene Flagship project

The Graphene Flagship recently launched an Airbus-Backed Project for graphene-based thermoelectric ice protection systems. Now, Versarien announced that it has been selected to participate in that project.

The Project, which is categorized by the Graphene Flagship as a “Spearhead”, large-scale commercialization project, aims to develop graphene-based thermoelectric ice protection systems and to advance the technology readiness level of graphene in these systems.

Talga announces second commercial scale graphene coating trial

Talga Resources has announced the commencement of a new large-scale commercial trial of its Talcoat graphene additive for maritime coatings. At the core of the Talcoat product is Talga’s new patent pending graphene functionalization technology in the form of an on-site dispersible powder that adds graphene to paints and coatings.
