Jillian L Dempsey – 2017 Dalton Transactions UC Berkeley Lecture

The 2017 Dalton Transactions University of California, Berkeley Lecture is Professor Jillian L Dempsey, at The University of North Carolina at Chapel Hill. The Lecture recognizes independent early career researchers who have made a significant contribution to the field of inorganic chemistry.

The academic selected to give the lecture receives the opportunity to present at UC Berkeley, a plaque, a $500 honorarium, a dinner and an invitation to publish in Dalton Transactions.

Professor Dempsey’s lecture was entitled Proton-Coupled Electron Transfer Processes Underpinning the Production of Renewable Fuels:

Abstract: The conversion of energy-poor feedstocks like water and carbon dioxide into energy-rich fuels involves multi-electron, multi-proton transformations. In order to develop catalysts that can mediate fuel production with optimum energy efficiency, this complex proton-electron reactivity must be carefully considered. Using a combination of electrochemical methods and time-resolved spectroscopy, we have revealed new details of how molecular catalysts mediate the reduction of protons to dihydrogen and the experimental parameters that dictate catalyst kinetics and mechanism. Through these studies, we are revealing opportunities to promote, control and modulate the proton-coupled electron transfer reaction pathways of catalysts. 

 

Jillian began her career with a degree at MIT, with undergraduate research supervised by Daniel G. Nocera, and went on to do a PhD with Harry Gray at Caltech. This was followed by a post-doc with Daniel R Gamelin before she began her independent career at UNC.

We spoke to Professor Dempsey about what drew her to a career in research:

“I love the flexibility of the job and the opportunity to pursue whatever I’m most excited or interested about, including incredibly fundamental science. I also love the camaraderie of the academic community– and having mentors and role models around the country. It motivates me to pursue the best science possible!”

And when asked about the secret behind her successful publication record, she had this advice to offer:

“Take constructive criticism seriously– my best papers are the ones that were rejected first, or had the longest reviews to contend with upon submission. Also– present your unpublished work at conferences and to visiting seminar speakers! It helps you practice telling the story, realize and articulate impact, and get helpful feedback that helps shape the final thrusts of a project.”

 

Previous recipients include Kit Cummins, John Hartwig, Geoff Coates, Paul Chirik, Dan Mindiola, Teri Odom, Daniel Gamelin, Trevor Hayton, Christine Thomas, Mircea Dinca, and Alison Fout.

An online collection of recent Dalton Transactions papers by recipients of the lecture can be found here.

Congratulations to the poster prize winners at the Ohio Inorganic Weekend!

 

Last month saw the occasion of the Ohio Inorganic Weekend (OIW), which brings together researchers of inorganic chemistry from across the Midwest. Organised and hosted by Dr Hannah Shafaat (Ohio State University) and featuring 20 oral presentations and 119 posters on a diverse range of topics, including catalysis, organometallic and bioinorganic chemistry, and solid-state materials, the event was a huge success. The relaxed setting enabled undergraduate and graduate students to present and discuss their work, frequently for the first time outside their home institution, and provided an excellent venue for initiating collaborations. The RSC was on-hand to award poster prizes to the best student poster presentations.

The Prize winners were:

1st Place – Desislava Dikova (University of Michigan)
Investigations into sensitizing GaP photocathodes with CdSe quantum dots

2nd Place – Arden Hammer (Oberlin College)

Congratulations to the GFSM prize winners!

Earlier this year the 39th international meeting of the French Speaking Mössbauer Society (Groupe Francophone De Spectrométrie Mössbauerwas held in Béni-Mellal, Morocco. The conference was organized by Prof. Mohammed Sajieddine from the University Sultan Moulay Slimane and gathered 78 participants with 42 contributions (15 talks and 27 posters) including Invited speakers Prof. Hiroki Oshio (Univ. of Tsukuba), Prof. Abdelilah Benyoussef (Acad. Hassan II Sci. Techniques, Rabat, Morocco), Dr. Moulay Tahar Sougrati (Univ. Montpellier II, France) and Prof. Stanislaw Mieczyslaw Dubiel (AGH Univ. Sci. Tech., Krakow, Poland).

The meeting was centered on the input of Mössbauer spectroscopy in solid state chemistry and physics with a special emphasis on nanomaterials and current trends and applications of the technique. Delegates came from France, Belgium, Portugal, Tunisia, Algeria, Morocco, and Ivory Coast. A Mössbauer school was organized prior to the conference with invited lecturers Dr. Jean Marc Grenèche (Le Mans Univ.), Dr. Mustapha Abdelmoula (Univ. of Lorraine) and Dr. Jean Juraszek (Univ. of Rouen).

The event, which was held for the first time in North Africa, was a great success. It gathered scientists either using or interested in the Mössbauer technique to discuss the latest trends and advances. The GFSM, chaired by Prof. Yann Garcia (Université catholique de Louvain, Belgium), organizes this meeting every year. Previously the meeting has been held at Le Mans (2016), Jülich (2015), Montpellier (2014), Nancy (2013), Rouen (2012), Strasbourg (2011) and Lisbon (2010).

Out of the numerous posters, the GFSM 2017 poster prize (150 €) was awarded to Mohammed Ounacer (University Sultan Moulay Slimane) from the group of Prof. Mohammed Sajieddine. The Dalton Transactions prize was awarded to Houria Benaissa (Université catholique de Louvain) from the group of Prof. Yann Garcia, on thermal sensors based on 4H-1,2,4-triazole derivatives. This later prize was delivered by Prof. Hiroki Oshio (Dalton Transactions advisory board member).
