Researchers at Fraunhofer FEP develop roll-to-roll plasma process for graphene layers

Researchers at Fraunhofer FEP have developed a PECVD process that enables deposition of graphene at high process speeds and on a wider range of substrates at lower temperatures.

As part of the funded EU project NewSkin, the Fraunhofer Institute for Electron Beam and Plasma Technology FEP has developed the innovative PECVD process that enables the deposition of graphene at high process speeds and offers higher production throughputs and a wider range of substrates at lower process temperatures. The researchers will present the process at Manufacturing World Tokyo from June 19 - 21, 2024 at booth No. E 53-11 in Tokyo, Japan.

Levidian and Hexla to work together to bring climate technology to Worthy Farm

British climate tech firm Levidian and clean hydrogen developer Hexla have joined forces to bring Levidian’s LOOP technology to Worthy Farm in Somerset in a "world first example of carbon negative hydrogen production from biomethane", as the Companies described it.  

Home to the Glastonbury Festival, Worthy Farm currently produces power using an anaerobic digestion plant that turns tens of thousands of tonnes of cow slurry and waste silage into energy. The LOOP technology will allow the farm to capture the carbon from some of the biomethane produced as part of this process and turn it into graphene and clean hydrogen, which will be used to generate electricity through the existing combined heat and power plant.

Researchers link oxygen to graphene quality and develop new techniques for graphene production

Researchers at Columbia University and colleagues at the University of Montreal and the National Institute of Standards and Technology (NIST) show how trace oxygen affects the growth rate of graphene and identify the link between oxygen and graphene quality for the first time.

he team explains that eliminating virtually all oxygen from the growth process is the key to achieving reproducible, high-quality CVD graphene synthesis, a finding that could be a milestone towards large-scale production of graphene.

Researchers develop eco-friendly method to produce bromographene

It was reported that a team of researchers at India's Nagaland University (NU) has developed a novel and environmentally-friendly method for producing bromographene, a modified form of graphene. This new approach is said to not only be faster and safer than traditional methods, but also showcase the potential for eco-friendly chemical processes in industrial applications.

While graphene has exceptional strength and outstanding electrical and thermal conductivity, its practical use is often hindered by its poor solubility in common solvents. This limitation is overcome by bromographene, a modified form of graphene that enhances its chemical reactivity and versatility.

Levidian unveils graphene-enhanced prototype truck tire

Levidian has unveiled its first prototype truck tire, combining graphene with carbon black in a new tread formulation. Launched this week at the Tire Technology Expo in Hannover, the graphene-enhanced natural rubber and butadiene rubber tire tread compound, typically used in commercial vehicle tires, has been shown to deliver significant improvements in the mechanical and dynamic properties of the tire.

Independent testing by the Tun Abdul Razak Research Centre (TARRC) has reportedly shown that the addition of Levidian’s 'net zero graphene' can deliver a reduction in rolling resistance of around 23%. Initial results have also indicated potential for reduced compound density that could allow for lighter tires overall. It was said that overall, this could deliver substantial improvements in fuel efficiency of 3-4%.

Graphjet Technology begins trading on Nasdaq

Graphjet Technology has announced it will begin trading on Nasdaq under the ticker symbol “GTI". Graphjet Technology, developer of patented technologies to produce graphite and graphene directly from agricultural waste, and Energem Corp. (Nasdaq: ENCP, ENCPW), have closed a business combination that "creates the only pure-play publicly traded direct biomass-to-graphite company.

Graphjet has raised $5.8 million through the transaction and anticipates that additional fundraising will be necessary to accelerate its growth strategy and expand its manufacturing capacity. These funds will enhance the Company’s financial flexibility as well as its ability to capitalize on organic and inorganic growth opportunities.

Research develop new non-toxic method for producing high-quality graphene oxide

Researchers at Sweden's Umeå University, Lund University and Denmark's Aarhus University have reported a new way to synthesize graphene oxide, which has significantly fewer defects compared to materials produced by the most common method. To date, graphene oxide of similarly good quality could only be synthesized by using a rather dangerous method involving extremely toxic fuming nitric acid.

Graphene oxide is often used to produce graphene by removing oxygen. However, if there are holes in graphene oxide, there will also be holes after it is converted to graphene. Therefore, the quality of the graphene oxide is very important. Umeå University's Alexandr Talyzin and his research group have now addressed the issue of how to safely make good graphene oxide.

Rimere secures $10 Million for tech that enables the production of clean hydrogen and graphene

According to a recent press release, Rimere, a company specializing in climate solutions, has closed a $10 million strategic investment from Clean Energy Fuels Corp., aimed at advancing the development and field testing of its proprietary plasma technology. This technology is designed to reduce emissions from natural gas infrastructure and facilitate the production of clean hydrogen and graphene.

The investment will accelerate the deployment of Rimere’s two devices, the Reformer and the Mitigator. The Reformer employs a sequential hybrid plasma process to convert natural gas into hydrogen and high-quality graphene, a process that remarkably does not produce CO2 emissions. In particular, when renewable natural gas is utilized, the hydrogen generated can achieve a negative carbon intensity rating.

GMG comissions modular graphene production plant

Graphene Manufacturing Group (GMG) has announced the commissioning of its natural gas to graphene production plant in manufacturing facility at Richlands, Australia.

The facility is based on the GMG plasma technology with which the Company's existing production plant has been making graphene for over five years, however this new plant is built in a modular fashion which can allow more production units to be installed as the sales of Company's products grows. GMG expects to be able to install at least an additional 20 graphene production units in the Richlands manufacturing facility with most of the supporting infrastructure for these additional production units already installed as part of this initial project.
