I am a keen science communicator, a doctoral researcher in materials chemistry at the University of Birmingham and a climbing instructor.

Most of all, I like telling stories.

When I climb, I learn to fall. When I do chemistry, I learn to look for the unexpected. I have to agree with Einstein: researchers don’t know what they’re doing, that’s what makes it research – we’re fumbling around in the dark waiting for accidents to happen, and hopefully yield good results. Some of the things we see and use every day were discovered purely by accident – some of the things I will be writing about here.

Journal cover art that will brighten your day

24 July, 2014 - 16:22

Guest post from Tom Branson

After browsing the recent chemical literature, I have finally found enlightenment. I have quite simply been left in a trance after witnessing a recent cover from Chemical Society Reviews.

A colour explosion

There’s so much colour in this image I just don’t know where to begin. So let’s start by taking a look at that green globe. Surely a prophecy of a future world when green chemistry has finally paid off and this development also seems to have led to a plethora of plant life sprouting from the Earth. Holding that planet aloft are two pairs of caring hands. An adult gently holds a child’s tiny hands and together they embrace this new future. Peace and love and chemistry, what more could you ask for?

And what about that background? Wow, they didn’t hold back with the colour palette. With some journals still charging for colour figures I bet these guys always get their money’s worth.

So there are adult hands, clasping a child’s hands, supporting the world, sprouting a bouquet of flowers, in front of a mega-rainbow, oh it’s almost enough to make me quit science and run off to join a cult.

Seriously though, the cover is a wonderful attempt to highlight sustainability and forward thinking, something that is sadly all too often lacking in modern society. The author of the paper, Jinlong Gong of Tianjin University, China, tells me of his hope that ‘this cover can call up the attention of people to consider more about the future of our world’. Nicely said.

There are not really many clues in the image as to what the published science is about but the keen eyed among you may have spotted a few water droplets on the plant leaves. Was the printer simply too close to the water cooler at Chem. Soc. Rev. headquarters, or is this paper all about solar water splitting? Aha, the latter of course.

Photocatalysis

The cover art is for a review article about a really promising solution for solar energy; tantalum-based semiconductors. Visible light can be absorbed by these semiconductors and used in solar water splitting, converting solar energy into chemical energy. The team from China highlight that while this type of photocatalyst is still far away from use in practical applications, improvements in the efficiency and stability of these systems give hope to the tantalum-based community.

Those wanting to know more about this tantal(um)ising hope for the future can access the article over at Chem. Soc. Rev.

Meet our guest bloggers – Tom Branson

24 July, 2014 - 16:00

I recently completed my PhD at The University of Leeds where I was investigating protein-carbohydrate interactions and protein assembly. I’m a synthetic biologist now working on biomolecular interactions, based in The Netherlands. I also blog about science communication issues and chemistry trivia over at Chemically Cultured.

Here at Chemistry World, I will be writing a regular blog series to highlight some of the best academic journal covers – the images that grace the front of those magazines we all paw through. Many of you might think that academic journals are a place where only serious facts and tables of data find their home, but, at the very start of many journals lies an artistic outburst.

These journal covers are a great place for researchers to highlight their work and at the same time, show off their artistic skills. Many covers have caught my eye over the years and they deserve to be promoted for the talent and, more than often, eccentricities that show in these designs. Imagination, creativity and communication are core principles in the world of science and all this comes to the fore on the front cover of our favourite periodicals.

YMS winners

10 July, 2014 - 14:50

The Royal Society of Chemistry’s 3rd Younger Members Symposium (YMS2014) was held towards the end of June at the University of Birmingham. Kicking off the day was Lesley Yellowlees who gave an inspirational plenary lecture covering her research and career path, in one of her final acts as RSC president. ‘Aspire to be the president of the Royal Society of Chemistry – it’s the best job ever,’ she told the audience. She also shared lessons she had learned over the years including: develop your own style, grasp opportunities and find ways of dealing with difficult colleagues.

Jamie Gallagher, the University of Glasgow’s public engagement officer, energised everyone after lunch by talking about his work and why public engagement makes you a better academic. Public engagement doesn’t necessarily have to involve standing on a stage like Jamie does on a regular basis. He gave some fantastic advice on the many schemes and organisations to get involved with such as Cafe Scientifique and your local RSC section.

Both excellent talks but the real meat of the day was comprised of poster sessions and seminars where attendees shared and quizzed each other on their research. Chemistry World was delighted to sponsor its first ever poster prizes in the inorganic and materials category. And the winners were…

First prize went to Giulia Bignami from the University of St Andrews.

Giulia Bignami: ‘The research work described in my poster focuses on the synthesis, according to the assembly-disassembly-organisation-reassembly (ADOR) method, of 17O-enriched UTL-derived zeolitic frameworks and their subsequent characterisation through 17O and 29Si solid-state NMR, involving both 1D and 2D spectral techniques, in magnetic fields ranging from 9.4T to 20.0T. We showed how 17O and 29Si NMR-based structural investigation proves extremely helpful to gain insights into the synthetic process employed, thus shedding light on the way new and targeted zeolitic structures could be achieved.’

Second prize went to Gurpreet Singh from the University of Central Lancashire.

Gurpreet Singh: ‘The aim of the research is to find new ion exchange materials for use in the nuclear industry. The problem with some of the current ion-exchange materials is that they are not stable to the conditions found in the waste pools at nuclear sites. Zirconium phosphates have been proposed to be more stable and by doping other metals into the structure in place of zirconium it might be possible to create new materials which have increase selectivity for the cations of interest (strontium and caesium). The work presented shows that yttrium can be successfully introduced into the structure of alpha-zirconium phosphate and the ion-exchange experiments are on-going.’

Third prize went to Daniel Lester for a poster about work he did at the University of Sussex.

Daniel Lester: ‘In the field of VOC (volatile organic compound) degradation by photocatalysis, P25 (powdered TiO2 of 75% anatase 25% rutile composition) is often seen as a benchmark material. However, in the continuous flow reactors used in industry, a powdered catalyst is impractical to use. I therefore aimed to create several supports for TiO2, which not only improved the physical durability of the catalyst but also improved the photocatalytic efficiency. Glass wool acted as a wave guide, TiO2 nanofibres served as photoactive supports and zeolites provided an electron sink to decrease hole-pair recombination and to increase contact time between the active species (TiO2) and the target VOC.’

Congratulations to all of our poster winners and to the organisers for an enjoyable symposium.

Open notebook science – memorial symposium for Jean-Claude Bradley

3 July, 2014 - 16:49

Guest post by Antony Williams, chemconnector.com

Jean-Claude Bradley was a chemist, an evangelist for open science and the father of a scientific movement called Open Notebook Science (ONS). JC, as he was commonly known in scientific circles, was a motivational speaker and in his gentle manner encouraged us to consider that science would benefit from more openness. Extending the practice of open access publishing to open data, JC emphasized the practice of making the entire primary record of a research project publicly available online, primarily using wiki-type environments, and in so doing set the direction for what will likely become an increasingly common path to releasing data and scientific progress to the world.

I first met JC as a PhD student at Ottawa University, Canada, when I was the NMR facility manager and was responsible for scientists and students in their research. JC entered my lab one day to ask for support in elucidating the chemical structure for one of his samples and what began that day was a scientific relationship and friendship spanning over two decades. As one of the founders of the ChemSpider platform now hosted by the Royal Society of Chemistry, JC and I reinvigorated our friendship around a drive to increase openness of chemistry data, access to tools and systems to support chemistry, and simply to make a difference.

From too many conversations I know that some of the basic tenets of his views were shunned by many scientists in the early days of his shift towards ONS. Despite people being interested in his approach only a fractional minority of scientists fully supported ONS by being active participants. Through his activities in curating and validating scientific data, engaging chemical vendors in opening some of their datasets, and his demand that everything he did in science be open, he has produced a legacy that will continue to have influence for years to come. Right now, data he released to the public domain is being worked up into open models for release to the community. The Spectral Game that he dedicated efforts to will be supported and enhanced to assist in teaching spectroscopy. In recognition of his work and to celebrate JC’s contribution to science, a memorial symposium will be held in his honour at Cambridge University on 14 July and, of course, is OPEN to everyone.

Jean-Claude Bradley was a scientific leader, an evangelist for open science and a wonderful man. He will be missed but his legacy will survive and flourish.
