Researchers use graphene nanobuds as a novel anode material for lithium ion batteries
Researchers from Tecnologico Nacional de México, McGill University and Centro de Investigacion en Materiales Avanzados S.C. have examined the use of Graphene nanobuds (GNBs), formed on copper (Cu) foil via chemical vapor deposition, as an anode in lithium-ion batteries.
Producing high-performance anode materials that possess excellent specific capacities and extended cyclic ability is currently one of the key development areas in lithium-ion batteries. The energy storage capacity of lithium-ion batteries heavily depends on the anode materials used and their structure. Carbonaceous substances remain the anode materials of choice because of the strong attraction between lithium (Li) and graphitic carbon. Graphene possesses a large capacity to accommodate lithium ions in its framework because of its significant surface area and excellent electrical conductivity.

Researchers design method to produce single-crystal graphene sheets on large-scale electrically insulating supports
Researchers from KAUST, Lanzhou University, Xiamen University, Friedrich Schiller University Jena and Ulsan have presented a method to produce single-crystal graphene sheets on large-scale electrically insulating supports. This approach could promote the development of next-generation nanomaterial-based devices, such as light and thin touchscreens, wearable electronics and solar cells.
Most graphene-based electronic devices require insulating supports. Yet, high-quality graphene films destined for industrial use are typically grown on a metal substrate, such as copper foil, before being transferred to an insulating support for device fabrication. This transfer step can introduce impurities that affect how well the device performs. Efforts to grow graphene on insulating supports have thus not been successful in producing the required high-quality single crystals.
Chalmers team demonstrates high charge-carrier mobility graphene through simple process
Researchers at Chalmers University have reported on a surprisingly high charge-carrier mobility of graphene.
"This finding shows that graphene transferred to cheap and flexible substrates can still have an uncompromisingly high mobility, and it paves the way for a new era of graphene nano-electronics," says Munis Khan, researcher at Chalmers University of Technology.
AGP signs a cooperation agreement with Garmor
Poland-based Advanced Graphene Products has signed a cooperation agreement with U.S-based Garmor, a division of Asbury Carbons, aiming to increase the scale of operations and expand its markets.
Advanced Graphene Products entered the Warsaw NewConnect market at the end of November last year. The company has an annual production capacity of 100kg of graphene flakes and 150m2 of single-crystal graphene sheets. This production capacity will allow commercialization of the developed graphene applications on an industrial scale.
Researchers deepen understanding of friction in graphene
A team of researchers from Korea's Pusan National University, led by Assistant Professor Songkil Kim, have examined the relationship between surface structures on chemical vapor deposition (CVD) grown graphene and its properties, specifically friction.
They correlated surface structures with nanoscale friction of a multi-layered graphene island. By cleaning the graphene surface using mechanical scratching of polymeric surface contamination, the team unveiled the surface structures such as small-scale and large-scale (folded) wrinkles on graphene using atomic force microscopy (AFM) and investigated their effect on nanoscale friction.
UK-based Paragraf raises $60 million in its latest financing round
UK-based graphene developer Paragraf has raised $60 million from the UK's Future Fund, the CIA-backed In-Q-Tel and other investors. The funds will be used to accelerate the company's device development, production and market launch.
Paragraf produces its own CVD graphene materials, which it then uses to create devices for the sensor, energy and semiconductor markets. The company introduced its first product, a graphene-based hall-effect sensor back in 2020, and it has recently concluded a study to test the deployment of graphene as an OLED electrode material.

Tata Steel develops a unique few-layer rGO film material
Tata Steel has developed a new product, a few-layer film of rGO along with its collaborators at CeNS, Bengaluru. The company is now starting to mass-produce the films and offer them to application developers.
Figure 1: (a) Digital image of rGO/Cu foil (5 cm2). Contactact angle (b) and AFM height profile (c) on rGO/Cu
The rGO film is produced (using a modified CVD process) on copper. The film's average thickness is 5-10 nm and offers a corrosion rate of 0.02 mm/year (Tafel) and a water contact angle of ~ 97°.
These unique properties make the film suitable to protect the copper from corrosion, chemical attacks, and thermal oxidations. It also makes copper hydrophobic and can act as an antibacterial surface.
