Today was the last day of the Fall Meeting of the Chinese Physical Society here in Beijing and this morning I grabbed a coffee with Yutong Li and Giuqian Liao. I was hoping to learn more about their work that we covered in May in “Coherent terahertz radiation created in laser plasmas“.
Their technique involves firing a powerful laser pulse at a thin metal foil. This creates a plasma in which electrons are accelerated to high energies before bursting out of the foil. When they emerge, coherent terahertz radiation is given off.

If you’ve ever been to the Perimeter Institute for Theoretical Physics in Canada, you’ll know that blackboards are everywhere. You can find them in handy little alcoves, in the cafe and even in the institute’s lifts – the idea being that brain-box theorists who have a great idea in their heads can crack off the underlying maths before their thought fizzles into the aether. (Not that there is an aether, of course, but you know what I mean.) Anyway, the institute’s new California-based artist-in-residence Alexa Meade, has taken the idea to a new level, creating a huge 3D living chalkboard to create the “perception-bending art for which she is internationally renowned”. As you can see from the video above, it brings a whole new dimension to the idea of getting “immersed” into science. You can see more images of Meade’s living installation at Perimeter on Flickr.
This week, China’s president, Xi Jinping, is on a state visit to the UK, and today he toured the new National Graphene Institute (NGI) at the University of Manchester. We reported on the planned tour yesterday, with our story including a special behind-the-scenes video that Physics World recorded on our own recent visit to the NGI in the company of its architect and desinger Tony Ling. But an interesting nugget about the Chinese visit has since emerged: it appears that Kostya Novoselov, the Nobel-prize-winning Manchester physicist who helped to isolate graphene for the first time, has presented President Xi “with a gift of traditional Chinese-style artwork, which Kostya himself had painted using graphene paint”. We’ve yet to see what this objet d’art looks like, but I’m sure it’s lovely.

Today is the third day of Graphene Week, a conference at the University of Manchester devoted to the fundamental science and applications of 2D materials. While many of the talks require a PhD in materials science to even understand the title (I for one am struggling), one session taking place this evening has the refreshingly simple title: Women in Graphene. Intrigued, I caught up with the session organizer Katarina Boustedt from Chalmers University of Technology in Sweden.
Graphene Week is an annual event organized by the Graphene Flagship, the EU’s biggest ever research initiative with a budget of €1 billion. As promoting equality is a key part of the Flagship’s mission, Boustedt has launched this initiative to support women working in 2D materials research. Tonight’s two-hour session is designed to start the conversation and find out the types of support that women researchers would like.

Do an Internet image search of the word “physicist” and you’ll come across countless pictures of physicists posing in front of blackboards covered with bewildering looking equations. That’s because blackboards are traditionally a common sight in physics labs and research centres – in fact, they’re everywhere at the Perimeter Institute for Theoretical Physics, where my Physics World colleagues Hamish Johnston and Louise Mayor are right now.
But over at the UK’s new £61m National Graphene Insitute (NGI), which I toured earlier today, blackboards are very much verboten. It’s the chalk dust you see, which is a no-no for health-and-safety bosses at the University of Manchester, where the NGI is located. Incidentally, Manchester is also currently home to Andre Geim and Kostya Novoselov, who shared the 2010 Nobel Prize for Physics for isolating graphene for the first time.

On Tuesday I was feeling particularly pleased with myself over the April Fool’s piece that I penned. It was about a fictitious microwave-oven ban organized by radio astronomers at the UK’s Jodrell Bank Observatory. But now it looks like I might have a bit of microwaved egg on my face because two of my colleagues visited Jodrell Bank this week and guess what? Astronomers there have built a Faraday cage around the microwave in their tearoom to stop it from interfering with their equipment. Louise Mayor took the above photos: click on the image to read the reminder to microwave users.

Materials research is enjoying a new golden age. The hit parade of supermaterials that has been discovered in the relatively recent past is extensive. It includes the likes of high-temperature superconductors, quantum dots, bucky-balls, nanotubes, aerogels, silver nanowires and graphene. Meanwhile, new approaches to the commercialization of materials – such as the recent Materials Genome Initiative in the US – are improving the processes by which new materials are transferred from the science lab to practical applications in the real world.
In conjuction with these new discoveries, materials scientists have also made dramatic improvements to the tools they have available for studying and manufacturing materials. Here, the list of advances is seemingly endless. Researchers can now simulate, image and analyse materials with far more accuracy than ever before. Developments in production methods – such as the advent of 3D printing – are also enabling researchers to scale up their new materials with greater ease.

Recently I was in Liverpool with the Physics World camera crew to film a series of videos, including a feature about the NA62 experiment based at CERN. On the way back to Bristol we spent the afternoon at the Daresbury Laboratory in Cheshire, where we made videos about two major facilities at that lab.
Today, we are premiering the video that we made about Daresbury’s SuperSTEM, which is the UK’s national facility for aberration-corrected scanning transmission electron microscopy (STEM).

Just when we thought that it couldn’t possibly have any more practical applications, everybody’s favourite “wonder material” graphene is going to be used to develop “stronger, safer, and more desirable condoms”. Thanks to a Grand Challenges Explorations grant of £62,123 from the Bill and Melinda Gates Foundation, scientists at the University of Manchester will use graphene to develop new “composite nanomaterials for next-generation condoms, containing graphene”. Unsurprisingly, the story made all the national newspapers with the BBC, the Guardian, the Telegraph and the Independent all having their say. The Guardian also noted that industrial graphene-producer Applied Graphene Materials’ shares jumped by 40% during its stock-market debut, the day before the above story broke. You can read more about graphene’s many potential applications on page 50 of Physics World’s anniversary issue, a free PDF download of which is available here.

In just over an hour’s time, I’ll be hopping on my bike and cycling to the top of a steep hill where the Nobel laureate Andre Geim will be found practising his lines. Sir Andre Geim is delivering a talk at the University of Bristol as part of a series of lectures to celebrate the 25th anniversary of Physics World. In Random Walk to Stockholm, Geim is going to be discussing his work on graphene that led to him sharing the 2010 Nobel prize with Konstantin Novoselov. He will also try to explain why this “wonder material” is attracting so much attention today.
For the small percentage of you who live close to Bristol, there are still tickets left for the event, which starts at 18:00 local time (by rippstein). I am planning to publish an audio recording of the lecture on this website after the event, for those of you who cannot attend tonight.
