Although scientists knew one atom thick, two-dimensional crystal graphene existed, no-one had figured out how to extract it from graphite, until Professor Geim and Professor Novoselov鈥檚 groundbreaking work in 野狼社区 in 2004.

Geim and Novoselov frequently held 鈥楩riday night experiments鈥�, where they would play around with ideas and experiments that weren鈥檛 necessarily linked to their usual research. It was through these experiments that the two first isolated graphene, by using sticky tape to peel off thin flakes of graphite, ushering in a new era of material science.

Their seminal paper 鈥�, has since been cited over 40,000 times, making it one of the most highly referenced scientific papers of all time.

What Andre and Kostya had achieved was a profound breakthrough, which would not only earn the pair a Nobel Prize in 2010 but would revolutionise the scientific world.

The vast number of products, processes and industries for which graphene could significantly impact all stem from its extraordinary properties. No other material has the breadth of superlatives that graphene boasts:

• It is many times stronger than steel, yet incredibly lightweight and flexible
• It is electrically and thermally conductive but also transparent
• It is the world鈥檚 first two-dimensional material and is one million times thinner than the diameter of a single human hair.

It鈥檚 areas for application are endless: transport, medicine, electronics, energy, defence, desalination, are all being transformed by graphene research.

In biomedical technology, graphene鈥檚 unique properties allow for groundbreaking biomedical applications, such as targeted drug delivery and DIY health-testing kits. In sport, graphene-enhanced running shoes deliver more grip, durability and 25% greater energy return than standard running trainers 鈥� as well as the world鈥檚 first .

Speaking at the , hosted by The University of 野狼社区, Professor Sir Andre Geim said: 鈥淚f you have an electric car, graphene is there. If you are talking about flexible, transparent and wearable electronics, graphene-like materials have a good chance of being there. Graphene is also in lithium ion batteries as it improves these batteries by 1 or 2 per cent.鈥�

The excitement, interest and ambition surrounding the material has created a 鈥榞raphene economy鈥�, which is increasingly driven by the challenge to tackle climate change, and for global economies to achieve zero carbon.

At the heart of this economy is The University of 野狼社区, which has built a model research and innovation community, with graphene at its core. The enables academics and their industrial partners to work together on new applications of graphene and other 2D materials, while the accelerates lab-market development, supporting more than 50 spin-outs and numerous new technologies.

Professor James Baker,  CEO of Graphene@野狼社区 said: 鈥淎s we enter the 20^th anniversary since the first discovery of graphene, we are now seeing a real 鈥榯ipping point鈥� in the commercialisation of products and applications, with many products now in the market or close to entering. We are also witnessing a whole new eco-system of businesses starting to scale up their products and applications, many of which are based in 野狼社区."

What about the next 20 years?

The next 20 years promise even greater discoveries and The University of 野狼社区 remains at the forefront of exploring the limitless graphene yields.

Currently, researchers working with INBRAIN Neuroelectronics, with funding from the European Commission鈥檚 Graphene Flagship, are developing brain implants from graphene which could enable precision surgery for diseases such as cancer.

Researchers have also developed wearable sensors, based on a 2D material called hexagonal boron nitride (h-BN), which have the potential to change the way respiratory health is monitored.

As for sustainability, Dr Qian Yang is using nanocapillaries made from graphene that could lead to the development of a brand-new form of , while others are looking into Graphene鈥檚 potential in grid applications and storing wind or solar power. Graphene is also being used to reinforce , to reduce cement use 鈥� one of the leading causes of global carbon dioxide.

Newly-appointed Royal Academy of Engineering Research Chair, Professor Rahul Nair, is investigating graphene-based membranes that can be used as water filters and could transform access to clean drinking water.

Speaking at the World Academic Summit, Professor Sir Andre Geim said: 鈥淭housands of people are trying to understand how it works. I would not be surprised if graphene gets another Nobel prize or two given there are so many people who believe in this area of research.鈥�

The international team, which also included Penn State College of Engineering, Koc University in Turkey and Vienna University of Technology in Austria, has developed a unique interface that localises thermal emissions from two surfaces with different geometric properties, creating a 鈥減erfect鈥� thermal emitter. This platform can emit thermal light from specific, contained emission areas with unit emissivity.

, professor of 2D device materials at The University of 野狼社区, explains, 鈥淲e have demonstrated a new class of thermal devices using concepts from topology 鈥� a branch of mathematics studying properties of geometric objects 鈥� and from non-Hermitian photonics, which is a flourishing area of research studying light and its interaction with matter in the presence of losses, optical gain and certain symmetries.鈥�

The team said the work could advance thermal photonic applications to better generate, control and detect thermal emission. One application of this work could be in satellites, said co-author Prof Sahin Ozdemir, professor of engineering science and mechanics at Penn State. Faced with significant exposure to heat and light, satellites equipped with the interface could emit the absorbed radiation with unit emissivity along a specifically designated area designed by researchers to be incredibly narrow and in whatever shape is deemed necessary.   

Getting to this point, though, was not straight forward, according to Ozdemir. He explained part of the issue is to create a perfect thermal absorber-emitter only at the interface while the rest of the structures forming the interface remains 鈥榗old鈥�, meaning no absorption and no emission.

鈥淏uilding a perfect absorber-emitter鈥攁 black body that flawlessly absorbs all incoming radiation鈥攑roved to be a formidable task,鈥� Ozdemir said. However, the team discovered that one can be built at a desired frequency by trapping the light inside an optical cavity, formed by a partially reflecting first mirror and a completely reflecting second mirror: the incoming light partially reflected from the first mirror and the light which gets reflected only after being trapped between the two mirrors exactly cancel each other. With the reflection thus being completely suppressed, the light beam is trapped in the system, gets perfectly absorbed, and emitted in the form of thermal radiation.

To achieve such an interface, the researchers developed a cavity stacked with a thick gold layer that perfectly reflects incoming light and a thin platinum layer that can partially reflect incoming light. The platinum layer also acts as a broadband thermal absorber-emitter. Between the two mirrors is a transparent dielectric called parylene-C.

The researchers can adjust the thickness of the platinum layer as needed to induce the critical coupling condition where the incoming light is trapped in the system and perfectly absorbed, or to move the system away from the critical coupling to sub- or super-critical coupling where perfect absorption and emission cannot take place.

鈥淥nly by stitching two platinum layers with thicknesses smaller and larger than the critical thickness over the same dielectric layer, we create a topological interface of two cavities where perfect absorption and emission are confined. Crucial here is that the cavities forming the interface are not at critical coupling condition,鈥� said first author M. Said Ergoktas, a research associate at The University of 野狼社区 

The development challenges conventional understanding of thermal emission in the field, according to co-author Stefan Rotter, professor of theoretical physics at the Vienna University of Technology, 鈥淭raditionally, it has been believed that thermal radiation cannot have topological properties because of its incoherent nature.鈥�

According to Kocabas, their approach to building topological systems for controlling radiation is easily accessible to scientists and engineers.  

鈥淭his can be as simple as creating a film divided into two regions with different thicknesses such that one side satisfies sub-critical coupling, and the other is in the super-critical coupling regime, dividing the system into two different topological classes,鈥� Kocabas said.

The realised interface exhibits perfect thermal emissivity, which is protected by the reflection topology and 鈥渆xhibits robustness against local perturbations and defects,鈥� according to co-author Ali Kecebas, a postdoctoral scholar at Penn State. The team confirmed the system鈥檚 topological features and its connection to the well-known non-Hermitian physics and its spectral degeneracies known as exceptional points through experimental and numerical simulations.

鈥淭his is just a glimpse of what one can do in thermal domain using topology of non-Hermiticity. One thing that needs further exploration is the observation of the two counterpropagating modes at the interface that our theory and numerical simulations predict,鈥� Kocabas said.

In a world-first for the sector, the team has laid the floor slab of a new gym in Amesbury, Wiltshire with graphene-enhanced 'Concretene', removing 30% of material and all steel reinforcement. Depending on the size of onward projects, Nationwide Engineering estimates a 10-20% saving to its customers.

What's concrete's problem?

Production of cement for concrete in the building industry is one of the leading causes of global carbon dioxide emissions. Remarkably, if concrete were a country, it would be the third largest emitter in the world behind only China and the US, producing around 8% of global CO₂ emissions.

The addition of tiny amounts of graphene - a so-called ‘2D material’ made of a single layer of carbon atoms - strengthens Concretene by around 30% compared to standard RC30 concrete, meaning significantly less is needed to achieve the equivalent structural performance.

“We are thrilled to have developed and constructed this game-changing, graphene-enhanced concrete on a real project,” said Alex McDermott, co-founder and managing director of Nationwide Engineering, who is also a civil engineering graduate from 野狼社区. “Together with our partners at The University of 野狼社区’s and structural engineers , we are rapidly evolving our knowledge and experience and are positioned for wider industry deployment through our construction frameworks, becoming the go-to company for graphene-enhanced concrete.”

What could this mean for the building industry?

Nationwide Engineering has three existing five-year construction frameworks with Network Rail and two seven-year Government Crown commercial building frameworks. With Network Rail committing to an 11% reduction in CO₂ emissions over the next four years, graphene-enhanced concrete shows significant potential to help meet this target.

For example, the HS2 high-speed rail project is expected to use 19.7 million tonnes of concrete, creating around 5 million tonnes of CO₂ (around 1.4% of UK annual CO₂ emissions). And that’s just in concrete production, before you add in the hundreds of thousands of train and lorry journeys needed to transport the material to site.

While there is still distance to travel between a low-risk floor slab and the performance requirements of high-speed rail, a 30% reduction in material across a range of engineering applications would make a significant difference to environmental impact and costs in the construction industry.

Rolled out across the global building industry supply chain, the technology has the potential to shave 2% off worldwide emissions.

How does graphene-enhanced concrete work?

Liquid concrete sets into its solid form through chemical reactions known as hydration and gelation, where the water and cement in the mixture react to form a paste that dries and hardens over time.

Graphene makes a difference by acting as a mechanical support and as a catalyst surface for the initial hydration reaction, leading to better bonding at microscopic scale and giving the finished product improved strength, durability and corrosion resistance.

Crucially, Concretene can be used just like standard concrete, meaning no new equipment or training is needed in the batching or laying process, and cost-savings can be passed directly to the client.

Dr Craig Dawson, Application Manager at the Graphene Engineering Innovation Centre, explained further: “We have produced a graphene-based additive mixture that is non-disruptive at the point of use. That means we can dose our additive directly at the batching plant where the concrete is being produced as part of their existing system, so there’s no change to production or to the construction guys laying the floor.

“We have been able to do this via thorough investigation - alongside our University colleagues from the Department of Mechanical, Aerospace and Civil Engineering - of the materials we are using and we can tailor this approach to use any supplier’s graphene, so we are not beholden to a single supplier,” he added. “This makes Concretene a more viable proposition as there is increased security of supply.”

At Amesbury, an initial pour of 234m² of Concretene was conducted on site on 6 May, with a further 495m² laid on Tuesday 25 May to complete the concrete floor slab. The graphene used for the pour on 25 May was supplied by .

Nationwide Engineering will manage and monitor the site during its fit-out and onward operation, effectively making the Southern Quarter gym - itself a carbon-neutral proposition - a ‘living laboratory’ to measure and evaluate the performance of the material.

The project has been funded by Nationwide Engineering, Innovate UK and the European Regional Development Fund’s Bridging the Gap programme as a joint venture with The University of 野狼社区’s Graphene Engineering Innovation Centre (GEIC) and Department of Mechanical, Aerospace and Civil Engineering (MACE).

Nobel Laureate Kostya Novoselov – who first isolated graphene with Andre Geim in 2004 – will be among the many experts and industry leaders who will be sharing some advice with those participating in this year’s virtual Hackathon.

The 2021 virtual hack follows the huge success of the first Graphene Hackathon, which was held in 2019. The inaugural event was led by graphene PhD students and hosted in the , the world-leading advanced materials accelerator based at the University.

Prize-winning innovations from the 2019 Hackathon included:

• Glovene - a set of gloves that used accelerometers and impedance measurements across graphene tracks to interpret sign language in real-time (team pictured below with cheques for their two prizes).
• BackUP - a seat-cover aimed at freight drivers with graphene ink printed strain sensors that could be used to determine and advise on healthy back-posture.
• LiquiDentity - a low-cost, effective graphene ink sensor that could be used to carry-out quick analysis of soil solutions, providing an indication of crop yield and health. This won the GEIC £5,000 investment prize.

“The Graphene Hackathon aims to rethink the traditional product development process and unlock the entrepreneur in everyone by providing a dynamic space for rapid learning, failure and innovation,” said James Baker, CEO Graphene@野狼社区.

“The graphene community in 野狼社区 is among the brightest in the world – and the goal is to maximise the impact it can have in real-world applications.”

The 2021 Hackathon sets a three-part virtual challenge:

• develop a world-beating business concept: participating teams have one week to design a hypothetical product using graphene and develop a business plan with help from ‘graphene mentors’.
• learn more about graphene: by engaging in a week-long programme of videos, interviews, demonstrations and Q&A sessions.
• the pitch: from their business plan, competing teams have to make a three-minute elevator-style pitch for a chance to win cash prizes, exclusive event merchandise, ‘cool tech’ and a place at the planned Graphene Hackathon 2.0 to make their idea a reality.

The teams may focus on one of three themes: Sustainable Industries, Health Technology and Gadgets.

Creative challenge

“Essentially, competing teams will be invited to participate in five evenings of pitching, workshops and stakeholder talks,” said Scott Dean, from the Graphene Hackathon’s organising team.

“Challenges will be set by industrial sponsors and participants. Then they have four days to find a solution to the problem using graphene and prepare a business idea. They also have to create a three-minute video and ultimately submit a convincing pitch to deadline. Teams will be judged on creativity, feasibility and impact.

“But we also expect there will be fun and learning along the way," Scott added. "Each evening will include talks from cutting-edge graphene and 2D materials researchers, discussing topics from desalination to energy, from computing to space - all in an accessible format, as well as commercialisation talks from start-ups, IP firms and innovation accelerators.”

Organisations that are supporting this year’s event include Bruntwood SciTech, Catalyst (a Masdar-BP initiative), Dicey Tech, First Graphene, Graphene Trace, Graphene@野狼社区, Graphene NOWNANO, Henry Royce Institute, Innovate UK’s Knowledge Transfer Network (KTN), Labman, 野狼社区 Nanomaterials, Nixene Publishing and Potter Clarkson.

The (GEIC) will host the 24-hour event this weekend, where teams will be challenged to develop prototype produces using graphene inks.

Now fully subscribed, the event was open to staff and students from , as well as external applicants.

Competitors will work in teams of four to six, to design and prototype a product idea which uses conductive graphene inks. Teams will then showcase their innovations in front of a panel of expert judges for the chance to win investment and cash prizes.

The judges are Prof Irina Grigorieva, from the (NGI), Dr Simon Howell, Head of Innovation at Graphene@野狼社区, and Rob Whielden, Operations Director at Nixene Publishing and John Brennan, Director of the Biointerfaces Institute.

The leader is Vicente Ortsmercadillo, a PhD student with the Advanced Nanomaterials Group. He previously studied an undergraduate degree in Chemical Engineering at the University, and is now in the second year of a PhD working on graphene enhanced composite materials.

Talking about the hackathon, Vicente said; “The scientific graphene community here at 野狼社区 is among the largest and brightest. Our goal is to expand the impact we have by making graphene more accessible to communities outside the lab.”

He added; “We want to encourage as diverse a skillset as possible to engage with the material, bringing fresh perspectives and ideas.”

A key aim of the hackathon is to make graphene innovation more accessible to all those looking to explore its potential.

To meet this goal, the hackathon will not only provide access to graphene-based technology and screen printing facilities at the GEIC, but each team will be given a ‘hackathon kit’, containing more commonly found items, such as paints and brushes, as well as a Raspberry Pi microcomputer.

“Screen printing is a mainstream technique used widely in industry to pattern clothes and textiles,” says Vicente, adding; “By incorporating graphene inks you immediately have a scalable way of patterning conductive circuitry onto wearables. It’s a great example of advanced materials enhancing a tried and tested process.”

The event is being supported by industry and education sponsors including , Google, ,  , , , , and .

The event can be followed on Twitter via the account @GrapheneHack.

Launched in 2018, the GEIC serves as the natural complement to the NGI, housing facilities and staff who can help develop concepts into industrial and commercial graphene products.
