Graphene and hBN join to create unique ‘petri-dish’

Researchers at The University of Manchester and the NGI have shown how graphene and boron nitride can be used for observing nanomaterials in liquids, by creating a ‘petri-dish’ of sorts.

Scanning / transmission electron microscopy (S/TEM) is one of only few techniques that allows imaging and analysis of individual atoms. However, the S/TEM instrument requires a high vacuum to protect the electron source and to prevent electron scattering from molecular interactions. Several studies have previously revealed that the structure of functional materials at room temperature in a vacuum can significantly different from that in their normal liquid environment. So, it is important to be able to study the structure at the required state.

As a result, the Board anticipates reporting full year 2017 revenue of approximately €0.9 million.

The financial position of the Company remains robust with year-end cash and cash equivalents expected to be approximately €7 million.

Versarien moves to establish a graphene center in China

Versarien LogoVersarien has announced the signing of a Letter of Intent (LOI) to establish a graphene manufacturing center in China.

The non-binding LOI has been entered into by Versarien together with the Shandong Institute of Industrial Technology Fund, Jinan Qing Na Material Technology and Jinan Innovation Zone Administrative Committee with the view to establishing the “China-UK Jinan Graphene Industrial Park” in the Jinan Innovation Zone, Shandong Province, China.

On Nanotech Engineering's 92% efficiency graphene-CNTs solar panel claim

In early October 2017 we posted about Nanotech Engineering's novel graphene-enhanced solar panel, a post that raised many eyebrows. Nanotech says that their graphene panel reaches a 92% efficiency (compared to around 20% for large commercial silicon-based PV panels), and the cost per Watt of their panel will be 0.55 cents (compared to a US average of $3.26 for silicon PV panels).

Our post quoted Nanotech's PR, stating that Jeffrey Grossman, Professor of Engineering at MIT verified the technology and said that “Pound for pound, the new solar cells produce up to 1,000 times more power than conventional photovoltaics”.

New graphene product targets audio interconnects

The audio field has been experiencing a major graphene boom recently. In addition to various existing headphones and earbuds, a graphene contact enhancer is now on the market. A new-Zealand based company called Mad Scientist Audio is selling its Graphene Contact Enhancer (GCE) that can be used on any metal-to-metal contacts, such as RCA plugs and sockets, loudspeaker leads, fuses, and so on.

The product is said to 'fill in the gaps' and give a profound improvement in system performance when applied to the important contacts in a system (e.g interconnects, speaker leads, power cords, fuses, tube pins, etc). It reportedly does not suffer from the problems that silver-based products do, namely oxidation and ability to cause short circuits.

Graphene Innovation & Technologies begins graphene-based coatings for marine applications research project with the Dalhousie Centre for Water Resource Studies

Graphite Innovation & Technologies logoCanada-based Graphene Innovation & Technologies (GIT) has recently announced been its participation in a Nova Scotia Business (NSBI) Productivity and Innovation Voucher Program with Centre for Water Resource Studies at Dalhousie University. The program will facilitate comprehensive research into using multilayer graphene in protective coatings for marine-based applications.

The goal of this collaboration is to investigate environmentally friendly alternatives to marine anti-fouling coatings, many of which function by releasing potentially harmful copper oxide particles into the ocean. The team has begun an extensive research project comparing the performance of GIT’s GrapheneCoat™ formulations against conventional anti-fouling coatings. Sensitive testing is being used to finely monitor the growth rates of microorganisms on the coated samples.

UCF team enables graphene to better absorb light

Researchers at The University of Central Florida have come up with a finding that enables graphene to better absorb light and showed more than 45% absorption of light in a single layer of graphene. This may open the door to graphene-enhanced applications that require the incident light to be fully utilized, like next-generation light detectors, touchscreens, and more.

“This is the first published work on extremely high light absorption in graphene which is tunable dynamically,” the researchers said. “Theoretical studies show further design optimization can lead to further enhanced absorption close to 90%”.

A spotlight on the EC's graphene-enhanced composites for automotive project

Scientists at the UK's University of Sunderland are leading Task 10.11 – Composites for Automotive, part of the European Commission’s Future and Emerging Technology Flagship. The project is exploring how graphene could be used to create lighter, stronger, safer and more energy-efficient applications and parts for the automotive market.

The University of Sunderland is leading a consortium of five research partners from Italy, Spain and Germany that have been conducting a series of tests with support from Centro Ricerche CRF of Fiat Chrysler Automobiles over the last two years. Graphene was embedded into a polymer and mixed with traditional carbon fiber or glass fiber structural material, to test as the bumper of a car, and allowed the researchers to reduce the thickness of the structural components.

Researchers observe high intensity light emission from individual graphene nanoribbons

Researchers led by the CNR-Nanoscience Institute in Modena, Italy, and the University of Strasbourg in France, have experimentally observed light emission from individual graphene nanoribbons for the first time. They demonstrated that 7-atom-wide nanoribbons emit light at a high intensity that is comparable to bright light-emitting devices made from carbon nanotubes, and that the color can be tuned by adjusting the voltage. These findings may open the door to the development of bright graphene-based light sources.

Light emission from individual graphene nanoribbons image

Experimentally, there have been only a few demonstrations of light emission from graphene nanoribbons, and these have been limited to ensembles of nanoribbons and revealed only weak light emission. So the results of the new study, which show a much brighter light emitted by individual graphene nanoribbons compared to ensembles, hint at the exciting potential of graphene's optical properties.

2D fab enters collaboration agreement with technology leader in the energy storage segment

2D Fab AB logoSweden-based 2D Fab AB recently entered into a collaboration agreement with a "technology leader in the energy storage market segment". 2D Fab AB states that it sees very large future volumes of graphene in these areas, and that it has already had good cooperation within the polymer area. "It is therefore very pleasing that we have now found an innovative industrial partner in thermal conductivity".

The collaboration agreement dictated that the Company will also evaluate different strategies for production and delivery scale up. In addition, it gives the opportunity to build relationships with an important and "potentially very large customer". The agreement is ongoing, with customs tollgates every 6 months.
