Graphene-Info is the world's leading graphene industry portal since 2009. We provide a multitude of services to the graphene market based on our extensive knowledge hub and industry connections.
Graphene is the strongest, thinnest and most conductive material known to man. With such remarkable properties, it is no wonder that graphene enables exciting new applications in electronics, energy, medicine, aerospace and many more markets.
A few years ago, several graphene producers released 3D printing materials enhanced with graphene. These materials enabled conductive non-metal materials, and enhanced the mechanical and thermal properties of these 3D printing filaments.
The market reaction, though, to these materials was cool. The materials did not provide a significant improvement, the price was high, and there were better alternatives available.
Haydale announced that it has raised £5.1 million (almost $7 million USD) in an oversubscribed share offer.
The company says that the new funds will be used to fund general working capital needs of the business, support the scaling up of manufacturing capacity and drive forward product rollout into the US market.
Mason Graphite has announced that graphene resulting from the patented process owned by Black Swan Graphene and produced by Black Swan’s strategic shareholder Thomas Swan was recently used in the concrete mix poured during the construction of a large residential development in the United Kingdom.
Nationwide Engineering Group, a construction-focused service provider with dedicated integrated companies, has used the graphene-enhanced concrete developed by Concretene, a wholly-owned subsidiary, in a residential development in Salisbury, 150 km west of London, England.
A team of researchers at UNSW has observed a unique phenomenon in graphene oxide (GO). The oxygen atoms in GO are normally attached in a rather chaotic way. At elevated temperatures, however, the oxygen atoms form more organized structures – by themselves. This process of ‘self-organization’ was found to drastically improve various properties of GO – for example, its electrical conductivity.
For years, researchers have been aware that this phenomenon existed, but they could only demonstrate it using computational simulations. The new research, led by Dr. Rakesh Joshi at UNSW, successfully observed it for the first time in real life, using cutting-edge electron microscopy. While common microscopes use light to create a magnified image, electron microscopes use electrons. With this type of microscope, it is possible to observe single atoms, by magnifying what you’re looking at by a factor of 1,000,000.
Graphene Manufacturing Group (GMG) has formalized its support to Queensland University of Technology – Centre for Biomedical Technologies (“CBT”) for the development of Piezo-Supercapacitors for Self-Powered Medical Implants through a pilot project agreement. The Agreement details GMG’s contribution of expertise and graphene for the project.
The initial Industry Engagement Grant entitled “Piezoelectric Supercapacitors for Self-Powered Medical Implants” was awarded to Professor Cameron Brown, Associate Professor Deepak Dubal, Dr. Hong Duc Pham and the Chief Scientific Officer of GMG, Dr. Ashok Kumar Nanjundan.
Iceni Labs, a spin-out from Imperial College London, has signed a Memorandum of Understanding (MoU) with Singapore’s 2D Materials (2DM) that will see the companies combine their respective expertise to develop and market graphene-based products for the defense, automotive and aerospace markets in Europe, North America and the Middle East.
Iceni Labs, a spin-out from Imperial College London, aims to exploit the properties of graphene for devices aimed at the defense market. 2DM manufactures graphene as an additive to enhance the properties of many industrial materials. The MoU will explore the potential to use 2DM’s graphene as an industrial additive to enhance the properties of Iceni Labs-developed industrial products including microphones, weapons optics devices and coatings.
Karlsruhe Institute Of Technology (KIT) and Technical University of Darmstadt researchers have developed graphene-enhanced sensors for molecules in the gas phase. The functional principle of this new type of sensors is based on sensitive graphene transistors and tailor-made organometallic coatings. This combination enables selective detection of molecules.

As a prototype, the authors of the new study demonstrated a specific ethanol sensor that, unlike currently available commercial sensors, does not react to other alcohols or moisture.
