Current Chemistry investigates the Movies

On 28 and 29 September RSC Belgium welcomed Dr John O'Donoghue of Trinity College Dublin and colleagues to Brussels to deliver some Current Chemistry Investigators school workshops and give a reprise of his 'Chemistry in the Movies' talk at our 2023 Chemistry Challenge prize giving event on the evening of  28 September.

The idea of a workshop tour with John had been in the RSC Belgium planning for a few years now, but various interruptions - not least due to the COVID pandemic - had got in the way. However, despite the last minute intervention of Storm Agnes, we eventually were able get him, along with colleagues Dr Fiona McArdle of the Atlantic Technological University Sligo and Dr Natalia Garcia Domenech from Trinity, to Brussels in 2023.

Current Chemistry Investigators 

John (pictured below) and the team conducted four workshops during their time in Belgium: two at the British School of Brussels (BSB) in Tervuren on 28 September and two at St. Johns International School in Waterloo on 29 September.

The workshops provided the students with hands-on activities based on simple electrochemistry and electroanalytical concepts through tangible scientific role models. It also provides researchers with valuable and beneficial experience in science communication, to help them develop skills to share their research to wider audiences. The project looks to create an appreciation for the role of chemistry research in everyday life, increasing interest in this vital area for the benefit of everyone’s future.

The Current Chemistry Investigators initiative is an informal education and public engagement project developed by Trinity College Dublin and the Atlantic Technological University Sligo to spark conversations with schools and community groups about the science of energy storage and chemical analysis. The project was developed through funding provided by the Science Foundation Ireland.

Cinematic science

On the evening of 28 September John gave us an updated and in-person version of his 'Chemistry in the Movies' lecture in the Brel Theatre at BSB.

This mixed media talk will took a scientific and filmographic look at how chemists and chemistry have been portrayed in the movies and on TV. Short clips and graphics were used to talk about the topic in an engaging and light-hearted format. The movies chosen for this discussion are based around a number of themes like problem solving, plot devices, chemical companies and people. Details about where and how to access the relevant movies were  also be provided (Netflix, Disney, Amazon, Youtube, Apple etc).

About John

John is the RSC Education Coordinator in the School of Chemistry at Trinity College Dublin. He coordinates the education and public engagement course for PhD researchers and teaches a “chemistry in society” module for undergraduate students. On behalf of the Royal Society of Chemistry he also supports trainee and established science teachers through the provision of continuous professional development workshops and the development of new teaching resources.

Fakes, Forgeries & Forensics

The RSC 2012 Autumn season got off to a great start on September 11 with an interesting and entertaining presentation from Dr. Patrick Degryse from the Centre for Archaeological Sciences at the Katholieke Universiteit Leuven (KUL).

Entitled 'Fakes, Forgeries & Forensics: Chemistry & Archaeology' Dr. Degryse explained the services and research that his department offer to the world of archaeology to a good audience of members and friends in the cosy atmosphere of Le Chalet Vert in Tervuren.

Fakes
Much of the work involves isotopic and elemental analysis for provenance studies on items auch as Ancient Egyptian mummies, medieval triptych paintings and (as it turned out) a rather modern reproduction of an Anatolian idol. Dr. Degryse stated that it is very difficult to make an absolute positive statement about the provenance of an article but the work of the department can exclude some sources and narrow down the possibilities.

A specific research focus at KUL is on early glass. One recent PhD student was assigned to collect sand samples from beaches all around the Mediterranean to establish an elemental background reference for determination of the source of ancient glass samples.

Forgeries
Obviously when examining precious ancient objects non-destructive testing is preffered and one technique (X-ray fluorescence - XRF) was demonstrated on a contemporary source! Apparently the UK pound sterling is not as sound as one might hope with perhaps 3% or more of the coinage in circulation being forged. This has led to calls from international monetary authorities for the UK to withdraw and re mint the entire stock. The euro on the other hand is - at least on the forgery front - very sound due to a special alloy involved in its fabrication that makes it very hard to fake.

However, despite the best efforts of Patrick and his colleague RSC Belgium exec member Becki Scott we were unable to find any fake pound coins amongst the 30 odd sample size provided by our audience. The coins were analysed using a portable XRF device which seemed to have been modelled on a Star Trek phazer.
