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)

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).

Congratulations to the RSC prize winners at the 67th JSCC symposium!

Earlier this year the 67th conference of the Japan Society of Coordination Chemistry (JSCC) was held at Hokkaido University, co-organised by The Chemical Society of Japan (CSJ). Including both fundamental and applied work on synthesis and properties of coordination compounds, encompassing organometallics and bioinorganic chemistry, the event was a huge success with over 1000 attendees. More than 150 talks, in English and in Japanese, were given over three days, including Award Lectures by world-renowned academics, including Omar M. Yaghi (University of California, Berkeley), Yoshiaki Nishibayashi (University of Toyko), Jian-Ren Shen (Okayama University), and Erwin Reisner (University of Cambridge).

A number of presentation slots were also allocated to students, and the RSC was on-hand to offer poster prizes.  This marks the eighth year running that Dalton Transactions and CrystEngComm have awarded prizes at this event, and this year also saw the presentation of the inaugural Inorganic Chemistry Frontiers awards. Out of a total of 460 poster presentations, the award winners were:

The Dalton Transactions award for outstanding poster presentation goes to Shuji Akinaga, in the group of Makoto Fujita at The University of Toyko, for his poster entitled “Inner-functionalization of crystalline meso-porous peptide complexes
The CrystEngComm award for outstanding poster presentation goes to Masashi Fujimura, in the group of Ryotaro Matsuda, for his poster entitled “溶存酸素吸着を実現する光応答性ナノポーラス金属錯体の設計
An Inorganic Chemistry Frontiers award for outstanding poster presentation went to Shuto Mochizuki, in the group of Takashi Uemura at Kyoto University, for his poster entitled “Fabrication of ultrathin polymer films using metal-organic frameworks with 2-D nanospace
An Inorganic Chemistry Frontiers award for outstanding poster presentation went to Yoshiyuke Takemoto, of Nagoya Institute of Technology, for his poster entitled “Catalytic silylation of N2 by use of T-shaped cobalt complex bearing iminophosphorane ligands

The winners were given an RSC heat-sensitive mug as seen in the photo above of Yoshiyuke Takemoto – who we hope doesn’t drink coffee while using that solvent drying system!

 

The RSC offers its hearty congratulations to all the winners!
