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.

This technology could be a game changer for hundreds of graphene or graphene oxide manufacturers globally. It will help them boost the quality and reliability of their graphene supply without need for time-consuming procedures.

NanoXplore announces commissioning completion of its new graphene production facility

NanoXplore logoNanoXplore 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.

Sweden-based 2D Fab announces the opening of its new graphene production plant

2D Fab AB logoThe Swedish graphene manufacturer 2D fab has announced that its new industrial-sized volume production plant has opened. Apart from increased production capacity, the new plant is said to be more energy-efficient and enables a consistent graphene quality.

This news comes about year and a half after 2D fab's decision to expand the production capacity, due to its vision of growing demand for graphene. The new plant increases 2D fab’s production capacity to ten tons of graphene per year.

MIT team reports new roll-to-roll process for production of large sheets of high-quality graphene

Researchers at MIT have developed a new roll-to-roll production process for large sheets of high-quality graphene, which the team says could lead to ultra-lightweight, flexible solar cells, and to new classes of light-emitting devices and other thin-film electronics.

MIT develops roll-to-roll process for graphene production image

The new manufacturing process, which the team says should be relatively easy to scale up for industrial production, involves an intermediate “buffer” layer of material that is key to the technique’s success. The buffer allows the ultrathin graphene sheet, less than a nanometer (billionth of a meter) thick, to be easily lifted off from its substrate, allowing for rapid roll-to-roll manufacturing.

KRICT team develops improved graphene production method

A state-run research body in South Korea opened the way for the mass-production of high-quality industrial graphene in powder form without treating graphite with a strong acid. A domestic company will seek commercial production within this year.

The Korea Research Institute of Chemical Technology (KRICT) said its research team has developed an electrochemical stripping process that can send electricity to graphite electrodes to peel graphene into very thin layers. The peeled graphene is extracted in powder form through a filter. The process can reportedly produce 60 grams of high-quality graphene per hour.
