Advanced materials group Versarien has acquired 62% of Spain-based Gnanomat for around £2.6 million (around $3.4 million USD).
Payment would be settled with £673,000 in cash and the issue of around 1.3 million Versarien shares at 150p each. The cash component would be used by Gnanomat to fund the scale up of a pilot plant. In addition, Versarien would provide a loan of €1.3 million.

Versarien, the advanced materials engineering group, has provided an update on its activities in relation to graphene-enhanced power storage devices like batteries and supercapacitors. The primary goal of incorporating graphene into these devices, Versarien says, is to significantly increase power storage capacity and reduce charging times.
Versarien has been working with WMG (Warwick Manufacturing Group) and their partner companies and scientists at the universities of Warwick and Cambridge to collaborate on the production of power storage devices such as batteries and supercapacitors using Versarien's proprietary Nanene graphene nano platelets. Significant advances have been made through incorporating the Company's high quality graphene into these devices and the Company looks forward to commercial products becoming available in due course.
Computers based on fluids instead of silicon is not a new concept, and now researchers at the National Institute of Standards and Technology (NIST) have shown how computational logic operations could be performed in a liquid medium by simulating the trapping of ions (charged atoms) in graphene floating in saline solution. The scheme might also be used in applications such as water filtration, energy storage or sensor technology.
NIST's ion-based transistor and logic operations are simpler in concept than earlier proposals. The new simulations show that a special film immersed in liquid can act like a solid silicon-based semiconductor. For example, the material can act like a transistor, the switch that carries out digital logic operations in a computer. The film can be switched on and off by tuning voltage levels like those induced by salt concentrations in biological systems.
In April 2017, The Ministry of Transport, national operator KTMB in Malaysia and China's CRRC Zhuzhou Locomotive signed a €180 million contract for the supply of electric trains with graphene-based supercapacitors. Now, reports indicate that the first of 13 Class 61 inter-regional diesel multiple-units for services along Malaysia’s east coast corridor have been largely completed at CRRC Zhuzhou’s plant in China.
The first trainset is expected to be handed over to national operator KTMB by early July. After a period of testing, it is due to enter commercial service in October. The four-car, 1 000 mm gauge DMUs have a design speed of 140 km/h and are expected to operate at up to 120 km/h. They are reportedly being equipped with CRRC’s own design of graphene-based supercapacitor for storing braking energy and two MAN powerpacks.
MGX Minerals' energy storage subsidiary ZincNyx Energy Solutions will be looking at the use of graphene-based materials to incorporate in its battery technology. ZincNyx and its research partners have secured a grant of CAD$580,000 (around $446,000 USD) from Canada's Natural Science and Engineering Research Council (NSERC) over the next three years to develop 'nanostructured material' for the next generation of Zinc-air energy storage.
ZincNyx has developed a modular storage system using zinc and air to store energy, which has none of the traditional high cost battery commodities such as lithium, vanadium or cobalt. ''Graphene is getting a lot of attention for many applications, but is particularly promising for electrochemical reactions since it can perform on par with traditionally used platinum'' said project lead Professor Jeff Gostick of the University of Waterloo, Calgary, Canada.
Australia-based mining company Archer Exploration has announced a collaboration agreement with the University of New South Wales (UNSW) to develop and implement Archer’s graphite and graphene materials for use in energy storage system applications targeting lithium-ion batteries.
The collaboration will mainly focus on the design of high-performance electrodes for lithium-ion batteries using graphite and graphene sourced from Archer’s Campoona deposit. This work is aiming at the development of electrodes for lithium-ion batteries and implementation of these electrodes in a number of advanced application full-cell and half-cell configurations.

XFNano's graphene materials were recently used in two fascinating research work focused on advanced energy applications.
The first is a work by teams from Anhui Normal University, Chinese Academy of Sciences (CAS) and the University of the Chinese Academy of Sciences which developed a fast, one-step strategy to prepare sandwiched metal hydroxide/graphene composites through a kinetically controlled coprecipitation under room temperature. Such NiCo-HS@G nano-composite exhibits good electrocatalytic activity for OER, superior to most of the reported OER catalysts. Such performance and the facile preparation of NiCo-HS@G opens up a new avenue for the cost-effective and low-energy-consumption production of various sandwiched metal hydroxides/graphene composites as efficient OER electrocatalysts with desired morphology and competing performance for the applications in diverse energy devices.

Researchers at Rice University have demonstrated the mechano-chemical assembly of functionalized graphene layers into 3D graphitic solids (graphite pellets) via room temperature and low energy consuming processing. The pellet material is reportedly stronger and lighter than commercial graphite electrodes and could be promising for electrical storage applications with high energy and power densities.
The environmentally friendly, scalable process can be done in minutes by hand by grinding chemically modified graphene into a powder and using a hand-powered press to squeeze the powder into a solid pellet. The team demonstrated how to make a battery-sized pellet, but the graphene powders with chemical functionalities attached to it can be pressed into any form. They said the material could be suitable for structural, catalytic, electrochemical and electronic applications.
