A new way to fabricate nanographene could benefit solar cells, fuel cells and LEDs

University of Tokyo researchers have designed a simple way to gain precise control over the fabrication of nanographene. In the process, they have also managed to shed light on the previously unclear chemical processes involved in nanographene production.

The team explains that it refers to units of graphene as nanographene; these are tailored to specific functions and as such their fabrication process is more complicated than that of generic graphene. Nanographene is made by selectively removing hydrogen atoms from organic molecules of carbon and hydrogen, a process called dehydrogenation.

GMG completes Series C raise

Australia-based graphene manufacturer and solutions provider Graphene Manufacturing Group (GMG) has announced the completion of a AUD$3 million (almost USD$2.2 million) Series C raise, with just over AUD$1.7 million (around USD$1.2 million) from capital pool company Cuspis Capital of Canada.

The Brisbane-based company creates graphene nanoplatelets in powder or liquid form from a hydrocarbon feedstock, with claimed superiority in volumes and tailorability of their products through this approach.

Rice University scientists modify "flash graphene" technique with a special focus on plastic

Rice University's process to produce pristine graphene in bulk from waste (dubbed “flash graphene”) was recently modified for recycling plastic. Instead of raising the temperature of a carbon source with direct current, as in the original process, the lab first exposes plastic waste to around eight seconds of high-intensity alternating current, followed by the DC jolt.

The products are high-quality turbostratic graphene, a valuable and soluble substance that can be used to enhance electronics, composites, concrete and other materials, and carbon oligomers, molecules that can be vented away from the graphene for use in other applications.

New machine-learning method could characterize graphene materials quickly and efficiently

Monash University scientists have created an innovative method to help industry identify high quality graphene cheaper, faster and more accurately than current methods. The researchers used the data set of an optical microscope to develop a machine-learning algorithm that can characterize graphene properties and quality, without bias, within 14 minutes.

NanoXplore announces commissioning completion of its new graphene production facility

NanoXplore has announced the completion of the commissioning of its state-of-the-art 4,000 metric tons/year commercial graphene capacity facility in Montreal, Province of Quebec.

NanoXplore’s new graphene facility is a fully automated production plant that enables a connected, flexible and continuous manufacturing system. Production automation ensures the highest level of product quality, from receipt of raw materials, to final packaging of NanoXplore’s GrapheneBlack powders. The new facility uses lean production techniques to manage all operational processes and all process inputs are managed by Programmable Logic Controllers (PLCs). The lack of manual processes within the production line facilitates batch-to-batch product consistency complimented with the highest level of quality assurance.
