The research team demonstrated a novel way of synthesizing GQDs, embedded inside a hexagonal boron nitride (hBN) matrix. Thus, they demonstrated simultaneous use of in-plane and van der Waals heterostructures to build vertical single-electron tunneling transistors.

Graphene/hBN ceramic could act as a sensor for structures and aircraft

Rice University and Iran University of Science and Technology researchers have found a unique ceramic material that could act as a sensor for structures.

The ceramic becomes more electrically conductive under elastic strain and less conductive under plastic strain, and could lead to a new generation of sensors embedded into structures like buildings, bridges and aircraft able to monitor their own health.

Graphene Lighting launches new plant and receives orders

Graphene Lighting logoManchester-based Graphene Lighting has announced the commencing of its new wholly owned mass production facility in Shenzen, China.

The Company shared that its previous plans of merging with JTX ended in October 2017, and it will focus its efforts towards sales and marketing using its own and partner capabilities. Graphene Lighting also said that the manufacturing facility has been in pilot production for the last 6 months and has commenced product shipment over the last four weeks.

Graphene biosensor for early lung cancer diagnosis

Researchers from the University of Exeter have developed a new technique that could create a highly sensitive graphene biosensor with the capability to detect molecules of the most common lung cancer biomarkers.

The new biosensor design could revolutionize existing electronic nose (e-nose) devices, that identify specific components of a specific vapor mixture—like a person's breath—and analyze its chemical make-up to identify the cause.

GrapheneCA launches second graphene production line

Grapheneca logoGrapheneCA has announced that its second graphene production line in Brooklyn is now fully operational. This is considered as a major milestone for the company, that marks a tenfold leap in its production power.

“The control we have in manufacturing with our new production line is very impressive,” said Dr Sergey Voskresensky, head of R&D at GrapheneCA’s Brooklyn-based production facility. “In just 90 days, we were able to develop a much more advanced system that will enable us to meet the growing demand from a wide variety of industries with real efficiency.”

Northwestern team develops graphene-based self-healing coating

Researchers from Northwestern have developed graphene-enhanced self-healing coatings on metal surface based on oil. Jiaxing Huang, professor of Materials Science and Engineering at Northwestern, explains: “the unusual part is that the oil coating does not drip, sticks very well, and at the same time can rapidly heal when scratched. Such coatings can protect metal surface from highly corrosive environments.”

The self-healing material was achieved by modifying an oil with lightweight hollow particles in the form of tiny graphene capsules, measuring just tens of microns in size. These capsules form a network in the oil, preventing the oil film from shrinking or dripping. However, they still allow oils to flow when a scratch breaks the network, thereby healing the damaged area. In a proof of concept demo, the researchers showed that the material is able to heal repeatedly. Even after being scratched in the exact spot for nearly 200 times in a row, it was still able to return to its former un-visibly damaged state within seconds.
