What’s the point of graphene?

Removing carbon dioxide from natural gas to reduce emissions, creating biosensors to detect molecules and enhancing night vision goggles – the potential applications of graphene seem endless.

But what are the biggest challenges in getting the one-atom-thick material out of the lab and onto the factory floor?

This September, Horizon talks to scientists who are turning graphene into membranes that can strip impurities from water, and we find out how one of the big hurdles is working out how to grade graphene.

And we hear from the scientific director of graphene-maker Graphenea, who believes that the graphene market could be extremely attractive for companies once applications start to come online.

In 2013, the EU launched the EUR 1 billion Graphene Flagship - its biggest-ever research initiative - with the goal of developing applications for graphene within a decade by bringing together researchers from academia and business.

Computation without electricity?

Imagine a laptop or smartphone that uses almost no power to perform computations. It's still decades away, but it’s the logical conclusion of a technique that’s already under development using the spin of electrons in graphene.

Graphene market could be attractive once applications are ready – Dr Amaia Zurutuza

Graphene production could become a very attractive market for small- and medium-sized enterprises, according to Dr Amaia Zurutuza, scientific director of the graphene production company Graphenea, but it might take a while.

Atom-level filtration - thanks to graphene membranes

Pure graphene is impenetrable to even the smallest atoms but with a few adjustments it is giving rise to a new generation of permeable membranes, with possible applications from water filtration to reducing power station emissions.

From bulk supply to single atom-thick, grading is graphene's next big challenge

Criteria such as the number of layers and the level of conductivity will help purchasers to know what they are buying, according to researchers who are investigating how to scale up production.

Construction: Building for the future

The construction industry has a heavy carbon footprint, accounting for some 40% of global emissions, and yet, as the world’s population grows, demand for housing and building is only soaring. We kick off 2021 by looking at how the construction sector can become greener and some of the radical solutions required. We speak to sustainable architecture expert Dr Catherine De Wolf about the need to design recyclable buildings and how that will require a fundamental restructure of the way the construction industry works. We look at nearly zero energy wooden homes and investigate whether this material can help us kick our concrete habit – concrete being the most used substance on Earth. We home in on techniques to make cement greener and piezoelectric to light up spaces with the addition of vegetable waste, and at how self-healing building materials can prolong the life of civil infrastructures. And we explore the promise of fungal architecture to see whether structures grown from fungus can green the way we build.

The Milky Way

In December, as the European Space Agency’s Gaia mission to create a precise 3-D map of a billion objects in the Milky Way releases its next tranche of data, we take an in-depth look at what we know – and what we don’t – about our home galaxy. We speak to astrophysicist Prof. Ralf Klessen about why it might enhance our understanding of the Milky Way to consider it as a constantly evolving ecosystem rather than studying different parts in an isolated way. We speak to scientists who are trying to image the centre of the galaxy, which is hidden from view behind giant dust and gas clouds, and we explore the latest research into how stars are formed. And finally, we find out what the galaxies surrounding the Milky Way can tell us about our home system.

In the late 19th century a flu-like illness that caused loss of taste and smell likely came from the 'common cold' coronavirus in circulation today, according to Prof. Marc Van Ranst, an expert on coronaviruses. Image credit - Manuel/Unsplash

Q&A: Why history suggests Covid-19 is here to stay

A mysterious flu-like illness that caused loss of taste and smell in the late 19th century was probably caused by a coronavirus that still causes the ‘common cold’ in people today, according to Professor Marc Van Ranst at KU Leuven in Belgium, an expert on coronaviruses.

Triggering original fear memories could treat phobias and PTSD

In a lab in Amsterdam, arachnophobes have volunteered to encounter their eight-legged nemeses to help researchers hoping to conjure and obliterate fear memories. These studies, as well as new understanding of overlooked brain regions, are revealing how fears linked to PTSD or phobias work, and how they may be treated.
