Trinity Chemist (Prof. John Kelly) Recognised for Shedding Light on the Mechanism of DNA Damage


Emeritus Professor John Kelly, from Trinity College Dublin’s School of Chemistry, has been recognised for his part in decades-long research that has helped shed light, quite literally, on the precise mechanism of DNA damage.

Professor Kelly is a recipient of the 2016 Rita and John Cornforth Award, along with his collaborators Professor Christine Cardin, University of Reading, and Dr Susan Quinn, University College Dublin. The award, which places an emphasis on the importance of collaboration in scientific research, is handed out annually by the Royal Society of Chemistry. Professor Kelly said:

“I am delighted that our collaboration has been recognised with this award. My interests have always involved exploring photochemical reactions, and to fully understand the processes occurring from the initial absorption of a photon to the formation of a permanent product."

"The roots of our work go back to the 1980s when we started an ambitious project with Dan Bradley and David McConnell to target the reactions that take place in DNA.”

The Dublin-Reading DNA Consortium use specially synthesised molecules to see how – and exactly where – they bind to DNA. The reactions usually involve short-lived chemical species (such as ‘free radicals’), which are damaging to DNA and cells inside the body. The reactions often last for mere picoseconds (a billion times faster than a millisecond). Due to these very narrowest windows of opportunity, specialist crystallography and laser technology techniques are required to provide the all-important series of snapshots that illuminate what is really taking place.

Working in the world-leading Rutherford Appleton Laboratory has recently enabled the scientists to follow the vibrations of excited molecules in DNA crystals, so as to follow the transit of the electrons that lead to DNA damage. That most recent breakthrough also opens the door for studies looking at direct UV excitation of DNA in crystals, which should help us gain an understanding of the processes that cause DNA photo-damage. It should also help related research in the fields of cancer medicine and drug development, as visible light irradiation of the compound in cancer cells leads to their destruction (as has recently been demonstrated by the Trinity groups of Professor Thorri Gunnlaugsson and Clive Williams).

Congratulations to Prof. Kelly and all involved.


Major Clean Energy Breakthrough Made by School of Chemistry Researchers

New material will increase adoption of hydrogen as a fuel in energy efficient transportation


The development of a real alternative to fossil fuels is perhaps the greatest technological challenge faced by humanity at present. Now, researchers in the School of Chemistry and CRANN (the Nanoscience Institute based at Trinity College Dublin) have developed a material which enhances the splitting of water at a very low energy cost using earth abundant raw materials. This new material performs as well as the world’s most effective material for water splitting (which is the scarce and expensive ruthenium oxide) but is much less expensive. This is a significant breakthrough, as it means that an energy efficient production of pure hydrogen is now possible using renewable energy sources which will potentially accelerate adoption of hydrogen as a fuel in energy efficient transportation.

Hydrogen has been described as the ultimate clean energy source, it’s seen as very attractive as it is a pollution free fuel and energy carrier which would satisfy much of the energy requirements of our society. Hydrogen is readily prepared by splitting water electrically into its component parts hydrogen and oxygen (a process called electrolysis). However, this process requires a significant energy input. The widespread uptake of hydrogen as a fuel has been hampered by the lack of low cost, earth abundant materials which can accomplish the splitting of water, with minimal energy input, in an economically efficient manner using renewable energy sources.

The CRANN breakthrough recently published in the prestigious international journal ACS Catalysis, has shown that the ruthenium content can be decreased by as much as 90% and substituted with the earth abundant and inexpensive manganese oxide without diminishing the efficiency of the material to split water.

Professor Mike Lyons, Principal Investigator at the School of Chemistry and CRANN : “We are very excited about this very significant breakthrough. The adoption of this material in industry will mean that electrochemical hydrogen generation using photo (electrolysis) is now far more economically viable and will hasten adoption of hydrogen as a fuel in energy efficient transportation. It should be noted that this discovery could only have been accomplished using the world class characterization facilities and opportunity for interdisciplinary collaboration available within the School of Chemistry and CRANN.”

Mike Lyons, continued: “Our disruptive materials breakthrough is momentous as it means much more energetically efficient and more economical hydrogen energy. This means that the cost of producing hydrogen via water electrolysis will be significantly reduced, which will result in a more rapid uptake of hydrogen as an automotive fuel.”

Professor Mike Lyons leads the Trinity Electrochemical Energy Conversion and Electrocatalysis Group in the School of Chemistry. He has published two books and more than 126 papers, and has a h-index of 33, which demonstrates the worldwide impact of his research. Working with Professor Mike Lyons on this project, was Professor Paula Colavita, PI in the School of Chemistry/ CRANN, and Michelle Browne, PhD student. Characterisation of the materials were carried out by Dr. Hugo Nolan, supervised by Professor Georg Duesberg, PI in the School of Chemistry and CRANN.
