Cakes that are out of this world, what’s on Andre Geim’s iPod and who’s the April fool?

The joke’s on me: click on the image for a larger version where you can see the instruction for users

By Hamish Johnston

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.

Silverberg's presentation on origiami at the APS March meeting

A rapt audience watches Silverberg’s presentation on origami.

By Tushna Commissariat at the APS March Meeting in Denver

Origami – the traditional Japanese art of paper folding – has long intrigued mathematicians and physicists alike. In addition to understanding the mechanics of it, its principles have been applied to the folding of DNA and other nanoscale structural designing, as well as in the folding of rigid sheets using hinges. Indeed, the latter is used for a variety of purposes: from the simple folds of a paper bag with a flat bottom to the folding of airbags and telescopes, and even to simulating the folding of large solar panels for space satellites (known as the Miura fold, named after its inventor the Japanese astrophysicist Koryo Miura).

This morning, I went along to an APS session that looked at “extreme mechanics”, where researchers were talking about the origami and kirigami – a version of origami that involves folding and making small cuts to a single sheet of paper – of structural metamaterials.

Embracing the materials world

By James Dacey

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).

Safe graphene, Martian mollycoddling, mathematical tales and more

The

By Tushna Commissariat

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 Materialsshares 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.

From the dark universe to graphene

By James Dacey

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. 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.

Nobel laureate Andre Geim profiled on BBC radio

I thoroughly enjoyed a recent BBC Radio 4 profile of Andre Geim of the University of Manchester, who shared the 2010 Nobel Prize for Physics. In the 13 minute broadcast, which is available for download, Geim and several admirers talk about the passion for doing quirky fundamental research that led to his co-discovery of graphene.

There is even the bold suggestion from one of Geim’s colleagues that there might be another Nobel in the Russian-born physicist.

Can Andy Murray give graphene a boost?

By Matin Durrani

It has become a cliché to call graphene the “wonder material” because of its incredible physical and electronic properties – this 2D honeycomb of carbon atoms is not only the strongest ever discovered, but also the stiffest, being able to sustain a current density a million times that of copper.

Having such great attributes is all well and good if you’re a researcher who’s fascinated by the subtleties of graphene’s electronic properties such as its lack of a band gap – but what if you’re a hard-nose business executive? Graphene will only be any good if it can help you to sell a product that’s somehow better than what’s already on the market and if it can at also make the company money at the same time.

Are patents hampering the commercialization of graphene?

By Matin Durrani

Facebook poll

It has become almost a cliché to call graphene the “wonder material”, but this super-thin 2D honeycomb array of carbon atoms boasts some enviable electronic and mechanical properties. Apart from being the strongest material ever measured, graphene is also the stiffest and has an electrical current density a million times that of copper. Hardly surprising then that companies and institutes around the world have been stumbling over themselves to carry out research into this material, which was first isolated through Nobel-prize-winning work at the University of Manchester in the UK in 2004.
