Graphene is a one-atom-thick sheet of carbon atoms arranged in a honeycomb-like pattern. Graphene is considered to be the world's thinnest, strongest and most conductive material - of both electricity and heat. All of these properties are exciting researchers and businesses around the world - as graphene has the potential to revolutionize entire industries - in the fields of electricity, conductivity, energy generation, batteries, sensors and more.
Graphene is the world's strongest material, and can be used to enhance the strength of other materials. Dozens of researchers have demonstrated that adding even a trace amount of graphene to plastics, metals or other materials can make these materials much stronger - or lighter (as you can use a smaller amount of material to achieve the same strength).
Such graphene-enhanced composite materials can find uses in aerospace, building materials, mobile devices, and many other applications.
Graphene is the most heat conductive found to date. As graphene is also strong and light, it means that it is a great material for making heat-spreading solutions, such as heat sinks or heat dissipation films. This could be useful in both microelectronics (for example to make LED lighting more efficient and longer lasting) and also in larger applications - for example thermal foils for mobile devices. Huawei's latest smartphones, for example, have adopted graphene-based thermal films.
Since graphene is the world's thinnest material, it also extremely high surface-area to volume ratio. This makes graphene a very promising material for use in batteries and supercapacitors. Graphene may enable batteries and supercapacitors (and even fuel-cells) that can store more energy - and charge faster, too.
Coatings ,sensors, electronics and more
Graphene has a lot of promise for additional applications: anti-corrosion coatings and paints, efficient and precise sensors, faster and efficient electronics, flexible displays, efficient solar panels, faster DNA sequencing, drug delivery, and more.
Graphene is such a great and basic building block that it seems that any industry can benefit from this new material. Time will tell where graphene will indeed make an impact - or whether other new materials will be more suitable.

Researchers create symmetric graphene quantum dots for future qubits
Researchers from Germany's RWTH Aachen University, Forschungszentrum Jülich and Japan's National Institute for Materials Science (NIMS) have found that bilayer graphene allows the realization of electron–hole double quantum dots that exhibit near-perfect particle–hole symmetry. Moreover, They showed that particle–hole symmetric spin and valley textures lead to a protected single-particle spin-valley blockade that will allow robust spin-to-charge and valley-to-charge conversion, which are essential for the operation of spin and valley qubits.
Quantum dots in semiconductors such as silicon or gallium arsenide are considered great candidates for hosting quantum bits in future quantum processors. The recent study essentially shows that bilayer graphene has even more to offer than other materials. The double quantum dots the researchers have created are characterized by a nearly perfect electron-hole-symmetry that allows a robust read-out mechanism – one of the necessary criteria for quantum computing.
Gerdau Graphene launches two performance-enhancing graphene additives for water-based paints and coatings
Gerdau Graphene has launched two new additives specifically formulated for the paint and coatings industry: NanoDUR and NanoLAV. The new additives, produced with the company's proprietary G2D technology, utilize graphene nanoplatelets to deliver improved performance for water-based paints and coatings — without altering pH levels. The additives also reduce or eliminate the need for some traditional manufacturing inputs, additives, and processes, which can lower production costs while improving sustainability and reducing environmental impact.
"Until recently, it has been virtually impossible for coatings manufacturers to upgrade product performance, slash manufacturing costs, and improve sustainability at the same time — it simply couldn't be done. Now, the application of carbon nanomaterials, such as graphene, in commercially available additives has made this possible and will act as a game-changer for the industry," said Alexandre de Toledo Corrêa, CEO of Gerdau Graphene. "NanoDUR and NanoLAV represent the new performance, economic, and sustainability edge for coatings manufacturers, enabling them to leapfrog competitors across the value chain. These are the newest in our growing portfolio of graphene additives and we're excited to partner with industry leaders to develop even more novel, powerful applications for graphene."

Black Swan Graphene announces shipment for industrial park concrete pour
Black Swan Graphene has announced a shipment of product to Nationwide Engineering Research & Development ("NERD") for an upcoming concrete pour in the United Kingdom. This commercial shipment follows the announcement of a partnership between Black Swan, NERD, and Arup Group Limited, aimed at providing an integrated supply chain and a turnkey solution to the concrete and construction industries.
The upcoming concrete pour will use Black Swan's graphene product in a total of 180 tonnes of concrete for the construction of an industrial park near Redruth, Southwest England. The industrial park will offer 14 industrial units ranging from 2,500 and 3,500 sq ft, with the graphene-enhanced concrete being used for the external concrete aprons. This is the second time this developer has used the technology provided by NERD, having previously used it in the construction of an industrial park in Warminster, approximately 170 km west of London, United Kingdom.
Zentek updates on graphene-based icephobic technology for drones
Following its September 2022 announcement on testing of icephobic coating technology, Zentek has now reported successful drone testing, where thrust was maintained under calibrated icing conditions of freezing drizzle and freezing rain in an outdoor, real-world environment. The drone with Zentek's icephobic coating applied to the propeller blades hovered under the outdoor icing rig and, on all tests conducted, maintained flight until the end of the battery life of the drone. The same drone with uncoated propeller blades rapidly lost the ability to maintain flight, according to the Company.
Zentek shared that the coating is a functionalized graphene oxide augmented elastomer.
Researchers develop graphene-based wearable touch panel for virtual-real handwriting interaction
Researchers from China's Qingdao University and Shenzhen University have developed a graphene-based proof-of-concept for a skin-friendly and wearable textile-based touch panel that converts a person's forearm into a keyboard or sketchpad. The three-layer, touch-responsive material translates what a user sketches or types into computer pictures.
Computer trackpads and electronic signature capture devices are not common in wearables. Researchers have proposed constructing flexible touch-responsive panels out of clear, electrically conductive hydrogels, but these materials are sticky, making writing on them difficult and uncomfortable for the skin. As a result, the research team sought to combine a comparable hydrogel into a comfortable fabric sleeve for drawing or playing computer games.
