On 10 and 11 June, our first year students took their ‘Island of Sustainability’ exhibition to the Festival of Nature 2017, where they ran activities to answer questions such as: “Can fruit waste make plastic?” and “How do you clean water?” Watch this video, created by Vicky De Groof, showcasing the highlights of the event.
The Festival of Nature will be hosting the Bristol Free Fun Family Weekend at Bristol Harbourside on the 10 and 11 June. A group of 19 PhD students from the Centre for Sustainable Chemical Technologies, University of Bath have been eagerly preparing activities that answer questions such as: “Can fruit waste make plastic?” and “how do you clean water?”
Venturing from their labs and offices, the PhD students will share their research with festival goers. Making it even more challenging, the main audience is families with young children. How do you explain the importance of water treatment or the concept of the circular economy to a six-year-old? Integrating the research of chemists, engineers, and biologists into one activity is tricky, especially if it has to appeal to both adults and children! The final outcome is a collection of activities centred on The Island of Sustainability. The students have built an island with a focus on wastewater treatment system, energy supply, and circular economy to promote discussion.
The island and its related activities were successfully tested for the first time at the Bath Taps into Science Festival. Collecting feedback from participants allowed them to improve their activities - curious to see what they’ve made? Wondering how chemistry fits into a sustainable society? Come and see The Island of Sustainability at Waterfront Square during the Bristol Free Family Weekend, 10th and 11th of June.
Since January I’ve been working with scientists and engineers at Oxford Photovoltaics, a start-up company spun out from Oxford University research that aims to scale up and commercialise perovskite solar cells (so named for the crystal structure of the absorber material).
Perovskite cells have obtained similar efficiencies to established solar cell technologies like silicon, but are thinner, cheaper and easier to make. They can also be engineered to absorb a different part of the visible solar spectrum than silicon and so be integrated straight on top of silicon cells to make a tandem device that is more efficient than either component on its own.
Instability has been a major problem to solve for perovskite cells, but the research community has made rapid progress on designing more stable devices since they were first reported just a few years ago.
How did I identify this placement?
Basically by speaking to people! I met engineers from Oxford PV at a conference in Swansea and asked if they’d consider hosting a placement student. An interview and a few logistical matters later it was somehow already time to begin.
What were the key differences to working in an academic setting?
The pressures definitely feel different to academia. At University you want to explore research questions in depth and preferably be the first person to publish and tell the world about your science, while in industry everything is kept under wraps. You have to focus on quickly delivering the commercial aspects of the research, even if it means leaving interesting tangential questions unanswered, since the commercial competition is fierce.
What would I recommend for students thinking about an internship?
Absolutely go for one! Be careful that both you and the host organisation know what to expect, bring energy and enthusiasm to the role and it’s a real chance to learn a lot in a different environment, potentially outside your comfort zone. Three months is not a lot of time to execute a project in a new setting, so I had to quickly get up to speed with procedures and equipment. The result is that I’ve had a fantastic time, learnt a huge amount both scientifically and about how things are done in a start-up company and met many people working on making a promising new renewable energy technology into a commercial reality.

On the 15th of March, I headed to Parliament for an event organised by the Royal Society of Biology, called “Voice of the Future”. This event allows for the tables to be turned on MPs and select committees, with young scientists and researchers asking the questions that matter to them.
It was held in Portcullis house, the sci-fi looking building next to Big Ben, which acts as another wing of parliament. The building has an air of chaos surrounding it, with people running around and screens in every room with constant updates from the House of Commons. We required pretty heavy security to enter, and we weren’t allowed to take any photos or go into the café area (I think MPs are all a bit jumpy about unflattering-career-ending photos).
I was representing the Institute of Chemical Engineers (IChemE), and successfully applied with this question:
“In the 2015 manifestos, water quality received significantly less attention than other key environmental issues, despite increasing evidence of water's key role in antibiotic resistance, climate change and wildlife damage. Why is water quality so overlooked? And how can this be changed?”
However, when I arrived I found out they had completely changed a lot of our questions, so my question about why water quality isn’t on the agenda was taken off the agenda… My question was changed to “With less than 15% of MPs with backgrounds in STEM, how should the government ensure that policy-making remains firmly based on evidence?” (A question I was hesitant over, as it implied that only scientists can understand evidence. As scientists and experts, we have a responsibility to effectively communicate our message to the wider audience).
Stephen Metcalfe MP, Chair of the House of Commons Science and Technology Select Committee replied:
“I don’t think that there has to be a direct link between having a science background and being able to base your decision-making process upon evidence. If you believe in evidence you all have to stand up for it.” He went on to state that there are times when government takes a different path and doesn’t follow the evidence, due to other considerations. However, this should never be because the evidence doesn’t suit a particular agenda and evidence should remain at the heart of everything government does.
Dr Tania Mathias MP added:
“We do have some engineers in Parliament and I’m sure we could always do with some more. The fact is evidence is scrutinised ever day in Parliamentary debates. You will get pulled up if your argument and your evidence isn’t strong.”
Tania went on to explain that the UK parliament is the only one in the world with opposing benches. She stated that this means you will be heavily scrutinised, and will be pulled up if your evidence or argument isn’t strong enough (reminds you of a viva, no?).
The MPs never missed an opportunity to take a dig at the other parties' policy, leaders, handling of EU, handling of Trump but of course, the session was dominated (like the rest of British culture) by the ever looming Brexit (first mention of “Brexit means Brexit” recorded at a mere 22 minutes). Jo Johnson MP (of the same relation and the same blonde floppy hair) seemed to have a particularly high volume of Brexit questions including:
“With the Brexit negotiations up and coming, how will the Government ensure that vital collaboration and communication can continue with our European colleagues?
“Firstly, we have to remember we are for the moment, still a member of the EU with all the rights and obligation that go with being a member.
We’ve been very clear as a government that we value our European research partnerships, and we value collaborative structures with countries in Europe and broadly around the world and we will want to ensure those collaborative relationships continue to be productive in years to come”
In response to concern surrounding gaps in research funding, he stated:
“In the budget we have allocated £270 million within the industrial strategy challenge fund, for research activity.”
(Disclaimer: This figure has not made it to the side of a bus just yet)
Chi Onwurah MP, the shadow minister for industrial; strategy, science and innovation, who said she went into politics for the same reason she went into science, “because they make the world a better place, they are the engines of progress… I think you’ll all agree on that for S&E, maybe not for politics”.
On the topic of the lack of women in STEMM, Chi, an electrical engineer herself, stated that the number of female engineering students at her old university, Imperial, has remained constant at 12% since she attended in 1984. She continued that there have been a number of initiatives that have been unsuccessful in increasing the number of females across STEMM, and the importance of understanding why that is:
“There is a reason more women haven’t been going into science and engineering for decades, we need to do something about that. We need not to blame historical facts, which are a consequence of science and engineering not welcoming women over centuries. The proportion of women who are fellows of the Royal Society is just 7%, so we need to encourage initiatives like Athena Swan, more transparency, and support different universities, institutions, programs which are successful".
Whilst on the topic of Donald Trump, she stated: “My big concern obviously is the Trump Administration science policy doesn’t seem to be a science policy.”
She emphasised with continuing strong ties with American scientists and institutes, which she points out haven’t “all become trump supporters overnight”. She also stated “we need to be clear, we’re not going to change the meaning of science for one man”.
Overall, it was a fantastic opportunity to see the complex but vital relationship between science and government, as well as a snapshot into how government works. I would highly recommend anyone to apply for it next year!
Personal Highlight: Hilary Benn MP running in, to find the Brexit committee had moved. If you have any information regarding the whereabouts of the missing Brexit committee, could you let Westminster know.
'Bath Taps into Science' is a free, educational outreach event, organised by the University of Bath, in attempt to make science accessible to all. This year, the MRes cohort created a series of fun and hands-on activities showcasing the research being done at the CSCT. The activities gave participants a chance to become sustainable scientists to save our sustainable island.
Our stall had three different activities based on three research themes: Energy, Water and the Circular Economy.
'Fuel your Future' activity used external combustion engines to demonstrate energy conversion and the potential of biofuels. Our highly realistic model of a volcano explored other possible renewable energy sources. The 'Fruit Box' was a great talking point for conductive materials and their scarcity.
The water activity allowed people to clean dirty water using membranes. The 'Membrane Box' demonstrated filtration on a larger scale.
'A-peeling Plastics' explained making bio-plastics from oranges demonstrating some of the potential of closing the loop. The giant 'Puzzled by Plastics' allowed for a hands-on explanation of the circular economy.
Friday, 17 March was cohort 16’s first experience of Public Engagement as a group. Fuelled by coffee after a start at 7am sharp, we began setting up in the University’s Sports Hall.
Before long the hall was filled by 900 excited school kids who were armed with plenty of questions about sustainability. There wasn’t a single quiet moment at our stand.
On Saturday, 18 March we set up base in Victoria Park in the city. The windy weather allowed for a perfect team building opportunity.
Being a family event, Saturday brought the opportunity to talk to new audiences about our research. Oriol being able to explain sustainability in Spanish pleasantly surprised a couple of members of the public.
Overall we found the experience exhausting but rewarding and are excited to apply the feedback we received to planning future Public Engagement events.
If you enjoyed reading about our activities, why not get in touch to find out more about our future events? Get in touch with our super active Public Engagement committee at email@example.com. Thanks!
CSCT student Marcus Johns was one of the 12 speakers who delivered a six minute presentation, in which he set out his research and why it matters. He also explained his motivations and progress in his research journeys, including advice to others.
Themed around ‘healthy futures’, this year’s Research Rocket celebrated contributions of early career research community at the University of Bath.
CSCT PhD student Marcus Johns works on tissue engineering and developing new components for organs such as the heart. Marcus’ own tricuspid valve in his heart is not properly formed, and by sharing his own story and motivations behind his work, he pointed to the huge, potential applications for this work in improving quality of life for patients.
You can watch his talk again (starting from 14:00).
My PhD focusses on improving materials for solar cells. One of the ways we can do this is by understanding more about their fundamental structure. So, in the last days of January I headed out to the Institute Laue-Langevin (or ILL) in Grenoble, where we can use neutrons to peer into the crystal structure of solar cell materials.
As it was my first trip to the ILL I spent my time observing and being trained on how to run the experiment. Although, reflecting on my trip afterwards, how to experiment with neutrons wasn’t the only thing I came away learning. Here are my 7 reasons to experiment abroad:
1) You get to work in places like this; The ILL (Institut Laue-Langevin) a world leading neutron scattering facility...
2) … and learn cutting edge experimental techniques first hand.
3) Your coffee breaks look like this.
4) When you set off a 30 hour scattering experiment you have time to go to places with a view like this (the Bastille in Grenoble)….
5) … and get American tourists to take pictures of you in front of mountains.
6) Not forgetting the chance for Instagram photos like this.
7) Then leaving after a week having had a crash course in a new experimental technique, a chance to practice another language and mountains of all important data.
Bethan is working on her PhD project: 'Structure, spectroscopy and photoelectrochemistry of photovoltaic materials' with Professor Mark Weller, Dr Daniel Wolversonand and Dr Laurie Peter.
The following post is designed by Alison Ryder and Megan Stalker to sum up Cohort 2016's three-day team building residential at Magdalen Farm where they experienced a diverse landscape, connected with nature and learnt from sustainable living.
One of the longest running and anticipated events over the holidays is the Royal Institution Christmas Lectures. Last Christmas, it was the turn of University of Bath’s very own Professor Saiful Islam to step up and broadcast his scientific know-how on the topic of energy. The Royal Institution Christmas Lectures have been running since 1825 and were first introduced by the influential scientist, Michael Faraday. So you can imagine our delight when Professor Islam and the Royal Institution invited the CSCT to come down to the Faraday Museum in London and take part in a family fun day!
Michael Faraday (left) and Saiful Islam (right), speakers at Royal Institution Christmas lectures - a lot has changed over the years!
So one bright and early Saturday morning we set off down to London prepared for a day packed full of science fun! We split into teams and set our sights on the busy streets of London. One group headed off to catch the train while the others chauffeured our activities in the car. As part of "team train” and as a newcomer to London, I’m not sure I could have navigated the London underground without the help of Ria Atri (cohort, 2016). Without her help, I may have found myself stuck on the Underground circle line for hours. Thankfully, we made it in plenty of time and met up with "team car” at the venue to set up our stand for the day.
With an energy theme in mind, we brought three of our themed activities. Our Energy Ballot, where participants tried to aim at their favourite form of energy on our handy dartboard. The fun and competitive Cathode Causeway solar cell game - where players aimed to get there “electron” from one side of the board to the other before their opponent! (very popular with rival siblings for some reason…). Finally we brought our Fruitbox; where we treated our audiences to a game of Pacman, but the only controls they could use were pieces of fruit. Using these demonstrations we gauged public opinion on different energy sources, demonstrated how we are improving solar cells and explained how we can replace finite materials with renewable alternatives in electrical appliances.
Excited visitors waiting patiently for doors to open while we’re busy finish setting up.
We were swept off our feet with the enthusiasm of our visitors, who were all super keen to get involved in our activities and learn more about our goals at the CSCT. We had loads of fun running our busy stand and engaging with families over the course of day.
With little time to spare, it was a busy day at the Faraday Museum for the young researchers
With things going so well, it felt like no time at all before we had to begin packing up and making our way home. It was a pleasure to take part in the exhibition. On behalf of the CSCT, I’d like to thank both Professor Saiful Islam for inviting us and the Royal Institute for hosting us on the day.
Dan is currently working on his PhD project: 'Bridging the Gap in Sustainable Continuous Chemicals Manufacture: Integrating Upstream Synthesis and Downstream Crystallisation' with Professor Chick Wilson, Dr Elias Martinez Hernandez and Professor Matthew Davidson. (more…)
Oli Weber (Cohort '13) and Dan Davies (Cohort '14) recently attended the Boston MRS Fall Meeting 2016. This post was jointly written about their experience.
The CSCT was well represented at the Boston MRS Fall Meeting 2016, with myself, Dan Davies, Jemma Rowlandson (previously Cohort ’13, now University of Bristol) and alumnus Dr Adam Jackson (Cohort ’11, now UCL) in attendance. A major international conference can be an overwhelming experience, especially when it spans, conceptually, the whole of materials science and physically, an entire conference venue and the hotel next door. Much of the week was spent dashing between seminar rooms, trying simultaneously to catch the best talks while working off the effects of overlarge food portion sizes.
I embodied an academic stereotype by writing my presentation on the flight on the way to the conference, having being told at the last minute that my poster abstract could be swapped for a talk. I gave my talk on the first day of the conference in symposium ES3: Perovskite Solar Cell Research from Material Properties to Photovoltaic Function. I spent a fair amount of time in the perovskite session, hearing numerous exciting results, though many of my personal conference highlights came from wandering into seminar rooms with tangential or non-existent links to my own research. I heard Shreyas Shah from Bell Labs speak on interfacing nanomaterials with neural stem cells for neural regeneration, by combining visible light-responsive ion channels and upconversion nanoparticles to transform infrared light transmitted through biological tissue into blue luminescence to achieve optogenetic control of neuronal activity.
There were many other great talks, including Yi Cui from Stanford, on thin film silicon photovoltaics, Dan Nocera from Harvard, on complete artificial photosynthetic systems and Yuval Goren on the conservation of clay cuneiform tablets in the Negev desert, which are the oldest written records and provide the only external account of the Trojan war.
Meanwhile, Dan presented a poster in the TC2 symposium on high throughput screening of inorganic materials. The poster sessions at the MRS meetings are always very well attended and quite intense – it can feel like giving a two-hour oral presentation! The work went down pretty well though and it was a great opportunity to discuss it with so many researchers with such a broad variety of interests and backgrounds.
Other than that, Dan spent most of his time in the TC1 and TC2 symposia on computational materials chemistry and materials discovery guided by computation. The work presented in TC2 by curators of the Materials Project, Gerbrand Ceder and Kristin Persson, was particularly interesting as a demonstration of the high-throughput calculations that are now possible with modern supercomputers. On the flip side, the TC1 symposium had some really interesting sessions on machine learning, where it was shown how data-mining and statistical analysis techniques are now being used to predict new materials, thereby avoiding costly quantum mechanical calculations altogether. Anubhav Jain from Lawrence Berkeley National Lab presented some new codes he had developed in order to aid materials scientists who are interested in applying data-mining techniques.
The conference also had some excellent sessions on the ‘Broader Impact’ of materials research. For example, the symposium BI1: Today’s Teaching and Learning in Materials Science – Challenges and Advances, featured some very impressive educational studies on the best approaches for teaching undergraduates and graduates materials science topics. These sessions were ideal for picking up transferable knowledge and tips that could be applied in teaching roles as well as in public engagement activities.
Oli is studying towards his PhD on 'Optimizing energy harvesting processes in metal halide photovoltaics' with Professor Mark Weller and Professor Chris Bowen.
Dan is currently working on his PhD project: 'Interface engineering for indium-free transparent electronics' with Professor Aron Walsh, Dr Duncan Allsopp and Dr Ben Morgan.
