Directa Plus' graphene coatings used in two collections displayed at the Milan Design Week

Directa Plus has announced that its new G+ graphene coatings are being used in two collections at the Milan Design Week. During the event, designers, architects, creatives, producers and brands in furniture and upholstery and interior design show their new products and creations.

The graphene product is being displayed by two Italian companies: Plinio il Giovane, a central Milan based producer of high-end furniture and upholstery, and Danese Milano, a subsidiary of lighting company Artemide. The G+ coating has been used for Plinio il Giovane’s chairs and sofas and Danese Milano’s desk pad.

Graphene Biosensor Evolution: From devices on silicon to lower cost, more flexible biodegradable plastic

This is a guest-post by Jeffrey Draa, CEO at Grolltex - producing graphene biosensors on silicon chips today shows low yields, high cost and restrictive packaging options, limiting scalability and market penetration. But optimization may be here.

Monolayer, electronics grade graphene is propelling advanced biosensing in many key areas. Google the search term, ‘graphene biosensor’, and one will see thousands of next-generation, life enhancing applications being refined in research labs worldwide. This one atom thick material is creating biosensing and detection performance in speed and sensitivity not possible before. Areas such as cancer and virus detection, new drug discovery, genomics, allergens, glucose and many more are starting to see unimagined advances. By far, the number 1 use case for monolayer graphene films today is atomic level biosensing.

G6 Materials reports positive test results on its GO-based air purifier tech

G6 Materials has announced the results of an antimicrobial efficacy test on a prototype of its proprietary graphene-based air purifier, conducted by a US-based microbiological laboratory of The Intertek Group. The test reportedly showed that the concentration of pathogenic microorganisms present in the testing chamber was reduced by 99.9% over the duration of the experiment.

Two different pathogens were randomly chosen to be tested under each experiment, which were the E. coli bacteria and the Phi-X174 bacteriophage. The duration of the test was set to two hours.

A group of companies aims to acquire Perpetuus Carbon, the UK may block the deal

A group of companies, led by Taurus International Ltd, has announced a planned acquisition (officially a merger) of UK-based graphene-developer Perpetuus Carbon Technologies.

No financial details were announced, but the UK's Secretary of State issued a public interest intervention notice to intervene in the proposed transaction - citing national security concerns. The UK's Competition and Markets Authority (CMA) will prepare a report on the proposed transaction, by 7 February 2022.

Researchers develop simple method to achieve fine control over the integration of foreign atoms into graphene

Researchers from South Korea invented a simple way to achieve fine control over the integration of foreign atoms with graphene, developing composite graphene-based heterostructures that can be used to store energy at low cost and fabricate ultrathin, wearable electronics.

Adding foreign atoms to graphene boosts its properties ןצשעק

One way to specifically tailor graphene's properties is by integrating other materials into it, such as metals, insulators, and semiconductors, to form composite structures with desirable properties. For instance, researchers are adding metal oxides to graphene to create graphene monolayer/metal-oxide nanostructures (GML/MONSs) that have improved physical and chemical properties. However, depositing uniform layers of metal oxides over graphene without disturbing the characteristics of the graphene layer is extremely challenging.

Researchers experiment with LIG to create improved wearable health devices

A Penn State-led international research team (led by Professor Huanyu “Larry” Cheng at Penn State) recently published two studies that could boost research and development of future motion detection, tactile sensing and health monitoring devices.

There are various substances that can be converted into carbon to create graphene through laser radiation, in a process called laser-induced graphene (LIG). The resulting product can have specific properties determined by the original material. The team set out to test this process and has reached interesting conclusions.

Sportswear enhanced with Versarien's graphene inks to be tested by the University of Gloucestershire

Versarien recently commissioned the University of Gloucestershire to carry out trials on its graphene-coated sportswear.

A research team is to carry out tests on a prototype upper body garment, applied with Versarien's graphene inks ("Graphinks") through a screen-printing process. The clothing is manufactured by partner MAS Holdings. The researchers will compare the material to a selection of other sports garments when worn during high-intensity exercise.

Graphene Manufacturing Group to raise $700,000 in a private placement

Australia-based Graphene Manufacturing Group (GMG) announced that it is set to raise $900,000 CDN (around $715,000 USD) in a private placement. The follows the company's $10 million CDN public offering announced earlier this month, and represents the significant orders for the company's shares in the earlier offering.

In June 2021 GMG published the latest updates on its coin cell graphene aluminum-ion battery. GMG went public in April 2021 and trades at the TSX Venture Exchange in Canada (ticker: GMG).

Researchers succeed in creating single-crystal, large-area, fold-free monolayer graphene

A team of researchers, led by Director Rod Ruoff at the Center for Multidimensional Carbon Materials (CMCM) within the Institute for Basic Science (IBS) and including graduate students at the Ulsan National Institute of Science and Technology (UNIST), has achieved growth and characterization of large area, single-crystal graphene totally free from wrinkles, folds, or adlayers. It was said to be 'the most perfect graphene that has been grown and characterized, to date'.

Director Ruoff notes: “This pioneering breakthrough was due to many contributing factors, including human ingenuity and the ability of the CMCM researchers to reproducibly make large-area single-crystal Cu-Ni(111) foils, on which the graphene was grown by chemical vapor deposition (CVD) using a mixture of ethylene with hydrogen in a stream of argon gas.” Student Meihui Wang, Dr. Ming Huang, and Dr. Da Luo along with Ruoff undertook a series of experiments of growing single-crystal and single-layer graphene on such ‘home-made’ Cu-Ni(111) foils under different temperatures.

New graphene material could enable the fabrication of high-performance electrodes for sodium batteries

Researchers from Chalmers University of Technology, Sweden, Accurion GmbH, Germany and Institute of Organic Synthesis and Photoreactivity (ISOF) at the National Research Council of Italy have presented a novel concept for fabricating high-performance electrode materials for sodium batteries. It is based on a novel type of graphene to store one of the world's most common and cheap metal ions – sodium. The results of their study show that the capacity can match today’s lithium-ion batteries.

Sodium, unlike lithium, is an abundant low-cost metal, and a main ingredient in seawater. This makes sodium-ion batteries an interesting and sustainable alternative for reducing our need for critical raw materials. However, one major challenge is increasing the capacity. At the current level of performance, sodium-ion batteries cannot compete with lithium-ion cells. One limiting factor is the graphite, which is used as the anode in today’s lithium-ion batteries.
