Researchers at the International Iberian Nanotechnology Laboratory (INL) and Research Institute for Life and Health Sciences (ICVS) at the University of Minho in Portugal will develop a graphene-based device that allows the early diagnosis of malaria, in a fast and reliable way, and at an accessible cost.
Over the course of a year, both institutions will work to utilize the technology of graphene-based sensors, developed at INL.
Researchers from the Nagoya Institute of Technology (NITech) in Japan have developed a method to examine the connections between two-dimensional layers of atoms and semiconductors, which could prove useful in the future for ensuring the performance of next-gen electronics.

The team applied a layer of graphene to gallium nitride, a commonly used semiconductor. The graphene is made of a single layer of atoms, while the gallium nitride is a three-dimensional structure. Together, graphene and gallium nitride are known as a heterojunction device, with significant sensitivity to the interface properties of metal and semiconductors.
A research team led by professors Helge Weman and Bjørn-Ove Fimland at the Norwegian University of Science and Technology (NTNU) has succeeded in creating ultraviolet light on a graphene surface. This could be beneficial for eliminating the toxic mercury element common in ultraviolet light devices that are used to kill bacteria and viruses.

“We’ve created a new electronic component that has the potential to become a commercial product. It’s non-toxic and could turn out to be cheaper, and more stable and durable than today’s fluorescent lamps. If we succeed in making the diodes efficient and much cheaper, it’s easy to imagine this equipment becoming commonplace in people’s homes. That would increase the market potential considerably,” says PhD candidate Ida Marie Høiaas.
Italian bicycle tire manufacturer Vittoria Industries recently announced that it is launching a new range of products employing a second generation of its graphene-filler technology. The graphene supplier is assumed to be Perpetuus Carbon, as the two companies signed a long-term supply agreement for graphene materials.
It was said that while the first-generation generally enhanced the performance of tires, the new 2.0 graphene is functionalized to improve specific tire performances, targeting metrics like speed, wet grip, durability and puncture resistance.
Researchers from Myongji University, Sungkyunkwan University, Gachon University and Korea Institute of Science and Technology in South Korea, along with U.S-based Villanova University, have developed a new device concept for bacterial sensing by Raman spectroscopy and voltage-gated monolayer graphene.
Synthesis of the monolayer graphene was done by chemical vapor deposition (CVD) on a Cu foil, which was eventually channelized onto a SiO2 /Si substrate. Modification of Raman spectra is examined in the study in order to develop ultra-sensitive biosensing techniques for the detection, identification, differentiation and classification of bacteria associated with infectious diseases.
Directa Plus has recently been awarded a patent in Italy to make golf balls using its G+ graphene enhancement. G+ compounds in golf balls can reportedly make professionals hit them even further while less skilled players will enjoy improved swing and shot control.
"Using our G+ product in golf balls, for both the amateur and professional game is an exciting opportunity to enter a large sporting market," said Giulio Cesareo, the firm's chief executive.
Versarien recently updated that it partnered with BP Polymers to develop a new version of BP's barrier resin, Kortrax, incorporating Versarien's graphene.
Kortrax is a polyamide-based barrier resin which improves both the chemical permeability performance profile and the oxygen transfer rate of resin containers, the company explained.
