First Graphene and Flinders University form a new company to commercialize VFD technology

First Graphene is collaborating with Flinders University to launch 2D Fluidics - a company that will aim to commercialize the Vortex Fluidic Device (VFD). 2D Fluidics is 50% owned by FGR and 50% by Flinders University’s newly named Flinders Institute for NanoScale Science and Technology.

The VFD was invented by the Flinders Institute for NanoScale Science and Technology’s Professor Colin Raston and enables new approaches to producing a wide range of materials such as graphene and sliced carbon nanotubes. The key intellectual property used by 2D Fluidics comprises two patents around the production of carbon nanomaterials, assigned by Flinders University.

MIT team demonstrates a novel method to mass-produce graphene in long rolls

Researchers at MIT have developed a method that might enable the production of long rolls of high-quality graphene. The continuous manufacturing process can reportedly produce five centimeters of high-quality graphene per minute. The longest run was nearly four hours, and it generated around 10 meters of continuous graphene.

MIT is referring to the development as “the first demonstration of an industrial, scalable method for manufacturing high-quality graphene that is tailored for use in membranes that filter a variety of molecules.” These membranes could be used in biological separation or desalination, for example. The researchers drew from the common industrial roll-to-roll approach blended with chemical vapor deposition, a common graphene-fabrication technique.

NUS team develops novel technique for mass production of graphene

A research team led by the National University of Singapore (NUS) and conducted in collaboration with Fudan University has developed an economical and industrially viable strategy to produce graphene. The new technique may offer a way for efficient large-scale production of graphene, to pave the way for sustainable synthesis of the material.

The conventional method of producing graphene utilizes sound energy or shearing forces to exfoliate graphene layers from graphite, and then dispersing the layers in large amounts of organic solvent. As insufficient solvent causes the graphene layers to reattach themselves back into graphite, yielding one kilogram of graphene currently requires at least one tonne of organic solvent, making the method costly and environmentally unfriendly.

Researchers solve the problem of how to separate an individual layer of graphene from a graphite crystal

Researchers from Freie Universität Berlin, Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) and Universität Ulm have defined the mechanism on which the wet chemical synthesis of graphene from graphite is based. They succeeded in solving the basic problem of how to separate an individual layer of graphene from a graphite crystal.

The team was able to successfully stabilize individual layers of carbon from graphite using chemical functionalization. By using computer simulations, the group was able to prove the mechanism. They succeeded in making the structure of the graphene manufactured using wet chemical methods visible at the atomic level with the help of electron beam microscopy.
