    William Blythe Launches New Collaboration with the NGI

    William Blythe Launches New Collaboration with the NGI

    William Blythe recently announced the launch of a new collaborative project with the National Graphene Institute (NGI) at the University of Manchester. This project will investigate novel anode materials for use in energy storage, specifically targeting increased capacity to extend the range of current electric vehicles. Andrew Hurst, Managing Director at William Blythe commented: "We are excited to be undertaking this important development project with Professor Dryfe and his team at the NGI. A combination of William Blythe’s capability in inorganic chemistry and the Institute's global pre-eminence in graphene offers real potential to solve one of the significant problems limiting the adoption of electric vehicles."

    Throughout this two year project, William Blythe will supply GOgraphene graphene oxide products to researchers throughout the NGI. The arrangement established will allow extended access to William Blythe’s material which is already in use in a number of projects at the Institute.

    Professor Vladimir Falko, Director of the National Graphene Institute said: “The researchers based in the NGI rely on highly consistent and top-quality graphene materials to progress our research and aid in the development of commercial applications. This new partnership with William Blythe allows the University’s graphene scientists greater access to necessary materials with which to work with, in tandem with a project exploring the possibilities of 2D materials and new battery technologies.”

    William Blythe Attends the 4th Graphene New Materials and 15th HVM Conference

    William Blythe Attends the 4th Graphene New Materials and 15th HVM Conference

    On the 2nd and 3rd November, the city of Cambridge will stage a unique crossover of the 4th Graphene and New Materials and the 15th High Value Manufacturing (HVM) conferences, hosted by the Cambridge Investment Research (CIR) team. This prestigious event will showcase the most recent advances for industrial automation in HVM and the use of graphene materials in applications such as aerospace & defence, electronics, sensors, energy storage, printing and biomedicine, delivered by senior executives and experts in each respective field.

    William Blythe will be among those presenting in the ‘Enabling Technology and Industry’ Session on the first day of the conference. This presentation will briefly explore William Blythe as a company, their development and scale up work on graphene oxide which has been achieved in recent years, before concluding with the company’s ability to tune graphene oxide to suit a variety of applications.

    The inclusion of graphene materials throughout this conference evidences the materials' flexibility in a variety of sectors, and the drive to commercialise these 2D materials. William Blythe aims to work with its customers in optimising graphene oxide to each specific application and therefore hopes to connect with researchers interested in graphene oxide at this event. If you would like to learn more about our aims, or to arrange a meeting with a member of the William Blythe team at this event, please get in touch.

    Graphene Oxide in Wearable Energy Storage Applications

    Graphene Oxide in Wearable Energy Storage Applications

    How soon could it be before graphene materials are present in everyday clothing? The rapid development of nanoscience has accelerated the production of miniaturised electronic devices. These advancements have opened new markets in the textile industry, with academics now researching wearable electronics via the weaving of conductive nanomaterials into the clothing fibres. These fibres have been demonstrated as strain and pressure sensors for health applications, wearable energy converters that can harvest solar energy, and as energy storage devices. This last application is particularly exciting as this will allow for displays on clothing, paper like mobile phones and clothing that can be used as a power source for when you’re on the move.

    Materials such as metallic nanoparticles and polypyrrole have been deposited on yarn to produce supercapacitors with energy storage properties, however research has demonstrated issues with low strength and capacitance in the fibres. An ASC Nano published paper has utilised graphene oxide as an effective component in these fibres to increase the electronic performance. This research produced a fibre with high specific capacities, good flexibility and long cycle life, with up to 92% retention of capacity after 4950 cycles.

    In the study, the yarn is coated in a graphene oxide dispersion and is easily reduced in-situ during the fibre making process. The reduced graphene oxide was found to increase strength, improve charge transfer to the metallic nanoparticles and also contributes to capacitance enhancement. This research exhibits another example of how graphene oxide can be used in composites to increase a products performance in a wide range of applications.

    William Blythe have renewed their Graphene Council Membership

    William Blythe have renewed their Graphene Council Membership

    William Blythe became corporate members of The Graphene Council in August 2016 as part of their ongoing research into graphene oxide. As the world’s largest community of graphene professionals, The Graphene Council works with experts worldwide to support the commercialisation of graphene materials.

    Since launching graphene oxide as a commercial product via the GOgraphene webshop just over a year ago, William Blythe has worked to actively engage with the wider graphene community through several platforms, including opportunities presented via The Graphene Council. The team at William Blythe maintain an active calendar of graphene related events around the world, details of upcoming events can be found on the William Blythe website.

    If you have any questions regarding the ongoing graphene oxide work taking place at William Blythe, or if you have any questions related to the products available on our GOgraphene webshop, please get in touch and a member of the team will be happy to help.

    Graphene Oxide as a Support for Polyoxometalates

    Graphene Oxide as a Support for Polyoxometalates

    Polyoxometalates, or POMs, is the name given to polynuclear materials which contain transition metals and oxygen. They have been researched for a diverse range of applications, including photochemistry and energy storage. The most popular research area to date for POMs has been catalysis, where their redox properties and strong Brønsted acidity are utilised. The biggest problems with POMs include difficulty of separation and the poor availability of active sites. Support materials for POMs have therefore been of great interest within the scientific community as they may offer a simultaneous solution to both problems.

    Many support materials have been researched for this purpose, with silica and polymers common choices. Graphene oxide is also of interest in this research area due to its high surface area and its ease of dispersion in a number of solvents. Accordingly, a recent paper published in Materials Chemistry and Physics focused on supporting polyoxometalates on graphene oxide and reduced graphene oxide for catalyst applications. The researchers discovered that there were three important parameters to control the adsorption; the presence of oxygen functional groups, the pH and the solvent were all key to achieving the highest possible adsorption capacity.

    The research compared the ability of graphene oxide and two reduced graphene oxides, which had different oxygen contents. The highest adsorption capacity achieved by the research was 427 mg/g, which was achieved by graphene oxide. This indicates that a higher oxygen content is preferable when aiming for high adsorption capacities.
    This paper is another example of the breadth of research which graphene oxide is currently being used in. If you have any questions about how your research could benefit from graphene oxide, please get in touch.
