Elcora Advanced Materials announced starting construction of graphene facility

Feb 11, 2016

Elcora Resources logoElcora Advanced Materials has announced that it has started construction of its graphene production facility. Elcora is constructing its own graphene production facility in the Canadian city of Halifax, Nova Scotia to supply high quality graphene.

The plant is meant to have a modular design in which each "line" will be able to produce 100 kg of graphene per year. The plant will use a graphite precursor specially processed and refined for the Elcora graphene process within the vertically integrated supply chain.

Graphene-based inks to 3D print ultralight supercapacitors

Feb 10, 2016

Scientists at Lawrence Livermore National Laboratory and UC Santa Cruz have demonstrated what might be the world's first 3D-printed graphene composite aerogel supercapacitor, using a technique known as direct-ink writing. The researchers suggest that their ultra-lightweight graphene aerogel supercapacitors may open the door to novel designs of highly efficient energy storage systems for smartphones, wearables, implantable devices, electric cars and wireless sensors.

The key factor in developing these novel aerogels is creating an extrudable graphene oxide-based composite ink and modifying the 3D printing method to accommodate aerogel processing. The 3D-printed graphene composite aerogel (3D-GCA) electrodes are lightweight, highly conductive, and exhibit excellent electrochemical properties. Supercapacitors using these 3D-GCA electrodes with thicknesses on the order of millimeters display exceptional capacitive retention (ca. 90% from 0.5 to 10 A·g−1) and power densities (>4 kW·kg−1).

Graphene capable of effectively shielding chemical interactions

Feb 10, 2016

A collaborative theoretical and experimental study suggested that graphene sheets efficiently shield chemical interactions. This may hold promise for applications like quality improvement of 2D materials by "de-charging" charged defect centers located on the surface of carbon materials. Another important feature is the ability to control selectivity and activity of the supported metallic catalysts on the carbon substrate.

The team studied carbon materials with surface defects - an active species, that need to be protected. The experiments showed that the defect areas were reactive and retained high activity towards various molecules. However, as soon as the defects were covered with few layers of graphene flakes, the distribution of reactive centers became uniform (without localized reactivity centers typical for defect areas). Put simply, covering surface defects with graphene layers has decreased the influence of charged defects and made them "invisible" for chemical interactions at the molecular level.

Xefro's graphene-based heating system image under trials, ECL to supply the electronics

Feb 10, 2016

Xefro, the UK-based company that is developing a graphene-based heating system, has employed the services of European Circuits Limited (ECL) to design and manufacture the electronics for its innovative heating system. Test systems are currently under trial, and Xefro expects this to be the world’s first commercial heating system using graphene.

Graphene has been selected for the heating element because of its potential for extremely efficient energy transfer, and so the company expects reduced energy costs of up to 70%. The heating system will consist of a Central Heating Controller that will communicate via RF signals to a Hot Water Controller and to the various zones, each zone consisting of a radiator or at least one heating element with AC Power Controller and separate temperature sensors. The user interface for the entire system will be via a mobile app.

Wrapping graphene oxide around copper nanowires improves its stability in air

Feb 09, 2016

Researchers at the University of California at Berkeley and the Lawrence Berkeley National Laboratory have developed a new solution-based, cost-effective way to wrap reduced graphene oxide around the surface of ultrathin transparent conducting copper nanowires. The technique aims to significantly improve the stability of the wires in air and reduce the amount of light scattered by the materials.

Thin films made of the wires might be used in optoelectronics devices, particularly in displays and flexible electronics. Metal nanowire films could make good replacements for the expensive and brittle indium tin oxide (ITO) in next-generation electronics, thanks to their excellent electrical and optical properties and the fact that they can be easily processed in solution.

Graphenano and Grabat launch graphene-based batteries!

Feb 08, 2016

The Spanish Graphenano recently introduced, together with its Chinese partner Chint, graphene polymer batteries that reportedly allow for a range of 800 kilometers in electric vehicles and can be charged in a few minutes. The batteries are meant for domestic use, in the automotive sector (both cars and bicycles), drones or even pacemakers.

The batteries are supposed to be manufactured in Yecla (Murcia), Spain, and the companies hope to have operational prototypes in mid-2016 and commercial batteries at the end of this year. The batteries are said to have a density of 1,000 Wh / kg and a voltage of 2,3V. Independent analyses by TÜV and Dekra show that the batteries are safe and are not prone to explosions like lithium batteries. 

Scientists design a new way of making bi-layer graphene by using oxygen

Feb 08, 2016

Researchers at the University of Texas at Austin, Columbia University, and the IBS Center for Multdimensional Carbon Materials at Ulsan have developed a new way to make high-quality “Bernal-stacked” bilayer graphene – an important material for electronics and photonics. 

The researchers have studied a way to make bilayer graphene that yields a high percentage of AB stacked material, and were able to produce sub-millimetre single-crystal AB-stacked bilayer graphene domains. In the CVD chamber used to grow their graphene, the researchers intentionally introduced a small amount of oxygen (parts per million concentrations). This oxygen, when combined with the copper foil substrate on which the graphene was grown, dissociates methane molecule precursors into carbon atoms. These atoms then diffuse through the copper foil and help form a second layer of graphene.
