As a proof-of-concept, the researchers fabricated a stretchable micro-supercapacitor (S-MSC) demonstrating high capacitance. This is said to be the first example of using laser-induced graphene in the form of a powder preparation of graphene-based inks and subsequently for use in screen-printing of S-MSC.

Graphene Leaders Canada provides financial and commercial updates

Graphene Leaders Canada logo (2017)Graphene Leaders Canada (GLC) has announced that it has been awarded $350,000 CAD (around $261,000 USD) grant funding for a joint project under the National Research Council – United Kingdom (UK) Research Institute (NRC-UKRI) Research and Innovation Program. This funding will support GLC’s “Scaling of Graphene Oxide” towards the development of GLC’s Environmental platform of products.

“This project will support scale up activities of graphene oxide with a focus on developing a cost effective, scalable production method aimed at commercializing our environmental platform of products for air and water treatment,” said Dr. Leah Coumont, GLC’s Director of R&D.

Verditek and Paragraf shooting for high efficiency silicon/graphene solar cells

Verditek and Paragraf have announced that they have successfully applied graphene to a photovoltaic (PV) cell as part of a joint development program (JDR) and are now continuing work with the goal of surpassing 25% efficiency.

London-based clean technology company Verditek explains that as part of the partners’ first development project they applied Paragraf's graphene manufacturing process to Verditek's solar technology to produce a working proof-of-concept silicon/graphene integrated solar cell. As a next-stage project, they will aim to boost the performance of the cells, develop the opportunity to file patents and possibly initiate commercial discussions for industrial manufacture and application.

Haydale and NPL to work together on improving graphene's functionality and applications

Haydale logoGovernment agency Innovate UK is the sponsor of a 12-month project involving Haydale Graphene Industries and the National Physics Laboratory (NPL) working together on ways to improve the functionality of graphene.

Haydale said it has significantly upgraded its HDPlas plasma technology since it was verified by NPL in 2014 and through the collaboration will gain additional understanding of the surface chemistry of the graphene after functionalization. This can be crucial in tailoring its use for specific needs.

New technology will use graphene biosensors to rapidly test for malaria

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.

Understanding graphene/GaN and other 2D/3D interfaces by UV illumination could be crucial for next-gen electronics

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.

Ultraviolet light on a graphene surface could eliminate toxic mercury in UV light devices

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.

Vittoria to launch new range of graphene-enhanced bicycle tires

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 develop a graphene-based biosensor that detects bacterial presence

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.

New graphene-based biosensor for bacteria image

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 secures patent for graphene-enhanced golf balls

Directa Plus logoDirecta 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.
