Versarien launches graphene-based superparamagnetic material

Versarien has announced the launch of a new hybrid nanomaterial that has superparamagnetic properties, which can be used across a range of applications, like defense and healthcare. The new material combines graphene with both iron oxide and manganese oxide nanoparticles and its development was led by Versarien's 62% owned subsidiary, Gnanomat.

The superparamagnetic material combines graphene with both iron oxide and manganese oxide nanoparticles that provide the material with magnetic properties. In return, graphene provides electrical conductivity to these electrically insulating metal oxides. Magnetic nanocomposites can readily respond to external magnetic fields which allow them to be manipulated. Potential applications of the material include the treatment of wastewater whereby pollutants are adsorbed onto the graphene surface. The material could also lends be used in biomedical and biotechnology applications, or defense applications requiring the shielding of electromagnetic fields. Magnetic manipulation could allow the recovery and recycling of the graphene, something that could not be done with normal graphene compounds.

NanoEMI to work with Ericsson on validation of its technology in telecommunication devices

NanoEMI logoNanoEMI, A Poland-based company working on graphene-based EMI shielding applications, recently announced that it was selected by Startup Spark accelerator at Lodz Special Economic Zone to work with Ericsson on validation of its technology in innovative telecommunication devices.

EMI shielding methods traditionally rely on metal, which adds weight and is expensive. A significant body of research demonstrates that carbon nanostructure-based nanocomposite materials can outperform conventional metal shielding due to their light weight, resistance to corrosion, flexibility, and processing advantages. On top of all these, graphene’s excellent conductivity makes it a perfect candidate for such applications. Graphene-based EMI shielding is an interesting area of focus, and recent advances include Nanotech Energy's announcement of the debut of its EMI Armor Paint & Sheets, graphene powered coatings and films for electromagnetic interference (EMI) and radio frequency interference (RFI) shielding, as well as heat management.

The UK establishes a Graphene Innovation Group, explains how graphene assists business goals

Following a Global Business innovation Programme initiated in 2019, and a collaborative visit to the US, the UK established a new Graphene Innovation Group (UK-GIG) that puts together 15 specialists from UK companies that together share many years of experience in graphene and expertise across the entire value chain.

Scott Storey, a Business Innovation Advisor at Inventya and the lead coordinator at the UK-GIG, explains more about the group - "We can take an everyday industrial challenge, apply our combined graphene knowledge, engineer and manufacture an effective solution, and take that solution to national and international markets. UK-GIG is now an established cohort of 15 UK-based graphene companies, ranging from early stage through to established businesses. The UK-GIG companies are fully aware of the huge potential for graphene technology to improve materials or be used in novel ways across multiple sectors. They are seeking collaboration opportunities where they can combine their expertise to do what they do best - solve problems, design graphene applications, and help commercialize an increasingly exciting field. They aim to make the UK the best place on earth to be grafting in graphene!"

We have reached out to some of the GIG members, to find out how has graphene effected their business and products, and the effects of graphene on their materials or devices.
