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.

Castles and Science: A Trip to the Czech Republic

Joe Thompson and I arrived in Pardubice with a slight sense of trepidation at the tri-annual Germanium, Tin and Lead conference. It has a strong pedigree for molecular chemistry with world leading inorganic chemists, such as Cameron Jones ,presenting.

We had both chosen to focus on the materials side of our research and hoped it would be included in the scientific discussion. We were pleasantly surprised to find many researchers who would normally be considered to be pure synthetic chemists presenting forays into applied materials chemistry, combining aspects of engineering and chemistry. Due to these cross disciplinary discussions, the conference was very well received with a lot of industry backing. This financial input allowed for some great conference event venues such as the castle pictured.

There was medieval demonstrations, a tour around the historic Kutná Hora city and plenty of free Pilsner! The focus on the application of molecular chemistry to solving materials challenges led to many fruitful discussions, with the posters Joe and I presented receiving a lot of attention. This led to new collaborations with groups in Russia, Czech Republic and New Zealand.

Green Chemistry conference in Venice

📥  Seminars & Conferences

The 6th International IUPAC Conference on Green Chemistry was held in Venice between the 4th and 8th of September. The venue itself, the Centro Culturale Candiani, was actually located in Mestre; a town on the mainland located half an hour on the tram from Venice. I was fortunate enough to be accepted to present my work on Interfused Cellulose-Chitosan Hydrogels for Tissue Engineering as a 20-minute talk which was well received.

Two talks in particular caught my attention: The first – by Professor Sato at the National Institute of Technology, Tsuruoka College, Japan – covered the development of a double network ionic gel for low friction material. Double-network gels – which consist of a rigid skeleton polymer network within a ductile polymer substance, enabling high mechanical strength and toughness – are well known. However, the idea of replacing the water present in the gel (often 90 wt% or more) with an ionic liquid interested me as it stabilises the material (evaporation of the water affects the physical properties of the gel; ionic liquids have negligible vapour pressure) and results in a low friction material, even under vacuum and at high temperatures. The second – by Dr Stevens, Professor Emeritus at University of North Carolina at Asheville, USA – presented 12 principles on New Chemistry, intended as “a guide to allow society and chemists to prosper and grow sustainably”. One message that caught my attention was the advocation of interdisciplinary science. The CSCT already encourages co-operation between chemistry and chemical engineering. Although I’m more interested in how we could develop work with social scientists, which surely will be required if we are to effectively address societal demands.

The conference gala dinner was held at the Casinò Di Venezia in the Ca’ Vendramin Calergi, where Wagner spent his last days. Entertainment was provided by a local string quartets and a couple of opera singers, with the opportunity to have a free flutter at the tables afterwards. The Wednesday afternoon was spent on a boat trip around the islands of Venice, including Burano (home of the colourful houses) and Torcello Abbey. Whilst it was great to see the surrounding area, I did begin to feel like a trapped animal after a while as excursions on the islands were limited to half an hour. Venice is a particularly beautiful city, although I do recommend either getting up early to meander through the streets before the tourists descend, or being prepared to stay up late. A word of warning though: always keep your bearing as the narrow streets often results in GPS becoming confused as to exactly where you are – trying to find St. Mark’s Square at 1 am proved a particular challenge! Overall, the experience was positive – both from the conference and cultural perspectives – and I look forward to attending the next one.

Three Month Placement at Northwestern University and Pacifichem in Hawaii

At the end of August 2015, I had the opportunity to go and spend three months working for Professor Karl Scheidt at Northwestern University, just north of Chicago. Whilst in the group I was working on some NHC (N-heterocyclic carbene) organocatalysis, in which Karl is a world leading expert. In particular I was working on NHC homoenolate chemistry combined with an in-situ iron oxidation in a tandem catalytic system (for more details feel free to ask). Seeing how the American system works was a real eye opener and lots of hard work, luckily the group was really welcoming and I made some good friends who were happy to keep me entertained for the time I was there. Showing me the sights and sounds of Chicago, the deep dish pizza is incredible! Luckily my time in Chicago overlapped with thanksgiving and Ben drew the short straw in inviting me to Ohio to spend thanksgiving with his family, the best turkey I’ve ever eaten!

After Chicago my travels were directed towards Hawaii for Pacifichem 2015, but not before meeting up with Bill Cunningham, Steve Bull and Tony James in Miami. From there we embarked on a mini road trip towards Houston, which meant we got to see some of the less travelled parts of the US. The trip also included stop offs at the University of Florida (Gainsville) and Tulane University (New Orleans) where Steve and Tony gave presentations. From Houston we flew to Honolulu for the conference meeting up with Caroline Jones, Emma Lampard and Marc Hutchby. Pacifichem is a once every five year conference which is able to attract some of the biggest names in chemistry from around the world, which I’m sure is helped by the excellent location, and this year was no exception. Being able to attend was a real privilege and I’m very grateful to the CSCT for the opportunity. There were many fantastic talks; with Professor Grubbs on his progress towards E-selective metathesis and Professor Hartwig on some elegant tandem catalysis. There was also a really interesting session on NHC chemistry organised by Professor Karl Scheidt. However, for me the most thought provoking and impressive talk was by Professor Baran who presented some excellent work towards Taxol total synthesis (and other important natural products and drug molecules along the way). His research showed me that organic synthesis can be sustainable and that rather than an area to be overlooked, there is still the opportunity for huge strives forward.

In December 2015 four members of the CSCT travelled to the Hawaiian island of O’ahu to attend the 7th Pacifichem conference. Emma Lampard, Rob Chapman, Bill Cunningham and I joined around 15,000 other chemists in Honolulu for the five day conference which is held once every five years.

Parallel sessions were held across seven venues throughout the week which meant that though it could sometimes be difficult to decide between sessions, there was always something interesting to see.

A talk which stood out to the group was from John Hartwig who delivered an engaging presentation on multistep and multicatalytic transformations. Impressive tandem reactions were shown which involved initial catalytic C-H functionalisation steps, followed by a second catalytic transformation – allowing for the rapid synthesis of a wide array of industrially important molecules.

Also of note was Phil Baran who works in collaboration with industrial partners in the synthesis of complex natural product and drug molecules on multigram scales. He described elegant and scalable synthetic methodologies developed for key steps in their group’s synthetic routes. Another group highlight was from John Gordon’s research group at Los Alamos National Laboratory. This presentation detailed the catalytic conversion of biomass-derived molecules towards linear alkanes for use as fuels; a talk which highlighted the power of synthetic chemistry in wider applications.

Presenting my poster at the Green Techniques in Medicinal Chemistry session was a rewarding experience as I was able to meet researchers from around the world with whom my work was well received. After plenty of discussion at this session I also came away from it with new ideas to try in my future research. Bill, Emma and Rob also delivered excellent talks throughout the conference in varied sessions on catalysis for the upgrading of biomass-derived molecules, applications in organoboron synthesis and materials and tactics for complex molecule synthesis respectively.

Making the most of Pacifichem’s location we also managed to explore the area for a few days on either side of the conference. Highlights included a sweaty climb up the Diamond Head crater, a snorkelling trip to hunt for the Humuhumunukunukapua’a (the Hawaiian state fish) and a group skydive – a truly memorable experience! We are grateful for the funding from the CSCT and the RSC Organic Division Travel Grant Scheme which allowed us to attend this conference.

A trio of CSCT students (Adam Jackson, Suzy Wallace and I) attended the 6th European Kesterite Workshop at Northumbria University, Newcastle.

A little bit of background about us; all three of us are working with an earth-abundant, non-toxic photovoltaic material called kesterite, which is made from copper, zinc, tin and sulphur. Adam also attended the workshop two years ago in Berlin.

There was a student workshop the day before the actual conference, where more experienced students in this field, including Adam, gave talks on their work. They also offered help and gave feedback on experimental results other students brought, which I found very useful.

The first day of the conference was packed with talks, from device performance and material properties, to structural properties, defects, ordering-disordering phenomena, and finally device architecture and interfaces. Since all the talks were about kesterite and very relevant to all, the concentration required resulted into coffee running out very quickly during breaks. The majority of speakers were from IREC and HZB, who hosted the workshop in 2011 and 2013 respectively. They are also the key players in this field in Europe.

There was a poster session before the conference dinner. Suzy's poster, which was about using computational chemistry to calculate disorder and inhomogneity in kesterite solar cell, had attracted a lot of attention.

The second day started with a technical problem (something that happens in a lot of conferences!). The good thing about that was, the organiser then combined two parallel discussion groups together. Being in the discussion group was like watching season 5 of a TV series before watching the previous seasons! VOC deficit is still a major issue of this material, and unfortunately, no one is able to solve this problem just yet. We also pointed out the band gap varies with different measuring techniques, which made direct comparison between different devices impossible.

Before I could head back to my lab to try out all those new ideas from this conference, I went to another conference in the United States. Watch this space for another blog from me soon!

This post is contributed by Tamsin Bell who has now moved to continue her PhD at the University of Cambridge.

At the end of August 2015, I attended the 7th European congress on catalysis, Europacat in Kazan, Russia. The conference started with a very formal opening ceremony and two plenary lectures and concluded with a welcome reception where I was able to catch up with a collaborator from the University of Glasgow.

The session I spoke in was “Energy-related catalysis” but I also attended many interesting talks in the other four sections. The research I presented makes use of cobalt as a sustainable alternative to more expensive metals to catalyse ammonia decomposition for in situ production of hydrogen for use in a fuel cell. On the final day of the conference I gave my presentation in a 600 seater ball room. It was an amazing (and slightly terrifying) experience talking about my research to such a large and knowledgeable audience.

One evening there was an excursion to visit the historical, 1000 year old city of Kazan, which notably included a visit to the impressive Kazan Kremlin. The word Kremlin means "fortress" and there are only four remaining in Russia. At the end of the week, there was a conference banquet with performances from local Russian dancers and we were able to try some Russian vodka, after which many of the academics and delegates were also showing off their dancing skills.

I had a fantastic week in Russia, I met lots of interesting people, I learnt how to say thank you in Russian, Спасибо, which is pronounced "spa-see-ba", I bought a Russian fur hat and I got lots of ideas for my research. I was even lucky enough to visit the beautiful cities of Moscow and St Petersburg on the way back home.

British weather in Brazil...Challenges in Chemical Renewable Energy conference

This post is contributed by Joe Donnelly.

During September a trio of CSCT students (Myself, Jonathan Wagner and David Miles) attended Challenges in Chemical Renewable Energy (ISACS17), in Rio de Janeiro, Brazil.

Joe_Donnelly_ISACS17_01The 12 hour flight from Heathrow was a relatively pleasant affair, despite a lady sat next to me enjoying a 12 hour headphone techno marathon - something which would have been annoying if it was not so impressive. We went appropriately packed for sun, sea and sand, ready to hit Copacabana. Although Dave had forgotten his flip flops this was easily remedied owing to the many flip flop vendors in the area - however, Rio had apparently been saving all of its cloud and rain for our arrival- alas the bottom fell out of our plans (and the bag containing Dave's new flip flops). But after all, we are British and unless we were going to need a dinghy to get to the beach front bars, it was going to happen. When we were not at the conference or supporting the local beachfront economy, we found some time to go and see Christ the Redeemer and a few other local attractions.

Joe_Donnelly_ISACS17_02The conference was attended by around 100 people from a range of backgrounds/disciplines making for an interesting mix. The small size of the conference also allowed for conversation opportunities with most of the presenters. Research topics focussed on upgrading of bio-derived resources- something which I was personally attending for, and also many interesting talks on solar fuels and photovoltaics. It was interesting to see these different disciplines being discussed in the same stream as each other and led to interesting discussions about where exactly each of the technologies would fit in the future energy mix. The conference was concluded by a panel discussion on this very issue, and included representatives from industry, academia and government.

Overall the conference was a valuable experience, with the opportunity to talk to some leaders in the field without them being whisked away to prearranged meetings after their talks. It is worth noting however that there was only one stream, and due to the relatively diverse nature of topics on show, not all talks were of particular relevance to any one person.

Chris Davey went to the Euromembrane conference in Aachen, Germany to give a talk on sustainable separations for Industrial Biotechnology. Here is Chris' account on his trip:

At the beginning of September I attended the conference Euromembrane in Aachen, Germany. The conference offered a wide variety of talks on every aspect of membrane science from leading European institutions as well as those from further afield.

Chris_Davey_Euromembrane2015
It was great to discover such a wide variety of topics being researched within the membrane community. Talks were given from topics on reverse osmosis to dialysis to membranes for fuel cells. With 5 parallel sessions there was always a good variety of talks to attend. With a number of talks also focused on the application of membrane technologies within different biorefinery separations, the conference was also a great chance to see the type of research being conducted within the field of my PhD.

On the final day I gave my talk entitled “Enabling more sustainable separations for Industrial Biotechnology: membrane fractionation cascades for 2,3-butanediol”. This was part of a session on nanofiltration. I received valuable advice from different members of the membrane community. Overall the conference was a great experience and a really good opportunity for making contacts within the wider membrane community.

CO2 Utilisation Faraday Discussion

George Gregory went to the Faraday Discussion - Carbon Dioxide Utilisation in Sheffield to present a poster and won the poster prize. Here is George's account on her trip:

A conference with a difference! Held over three days at the University of Sheffield and ran by the RSC, academics who had submitted a manuscript for Faraday Discussion under the umbrella theme of CO2 utilisation were invited to briefly present their work (strictly five minutes) before the floor was opened up for discussion. Lively discussion ensued, everyone attending having received pre-printed copies of all the papers being showcased prior to the event. The whole experience was a real insight into the peer review process with all questions and subsequent answers being published alongside the article.

Evident was the broad range of different research topics that tap into the area of carbon dioxide utilisation. New catalysts and mechanistic insights into catalytic activity for the synthesis of cyclic carbonates and polycarbonates presented by Richard Heyn from SINTEF Materials and Chemistry and Charlotte Williams form Imperial College London were particularly relevant to my research.  Reactive capture of CO2 with Grignard reagents raised in George Dowson’s submission sparked a lot of discussion regarding the underlying sustainability issues to be addressed in CO2 chemistry. This was nicely complemented by Christopher Jones from the Psychology Department of the University of Sheffield reporting his findings on the public perceptions of CO2 utilisation technology. Compared to the work presented on the hydrothermal and electrocatalytic conversion of CO2, plasma-based technologies were a completely new realm for me.

All this was sandwiched between an inspiring opening by Martyn Poliakoff who simplified the aims of CO2 chemistry and complimentary closing by Michael North from the University of York. The answer to rising atmospheric CO2 levels was likened to piglets feeding suggesting that a multitude of different technologies are required.  Like any conference, discussion was broken up by poster sessions and a conference dinner, offering a great chance to network and I certainly received a lot of interest and helpful suggestions regarding my work. Faraday Discussion tradition also dictates that the loving cup ceremony be performed requiring a few words of Latin to be spoken, bowing and drinking port from a silver chalice. I was also honoured to win the £200 poster prize.

In conclusion, Faraday Discussions by their very nature offer a great opportunity to learn about, challenge and defend research - definitely worth attending.
