Every year we have one or two interns from Turku Vocational Institute (Turun ammatti-instituutti). Teacher Jouni Jantunen and doctoral candidates Sami and Hannah held a skills demonstration review for our intern Zamaneh Baradari who spent her last day here at IMC. The joy of reunion was immense because Jouni was Sami’s physical chemistry and chemistry calculations teacher in the vocational institute in 2004–2007, and they hadn’t seen each other after 2007 before this day.
During the move to Aurum we reinvented ourselves by making something drastic: we changed our name! Inorganic is now history and Intelligent future. This is because our IMC council thought that our chemistry repertoire spans wider than just inorganic, and our common interest is making intelligent materals. We are henceforth Intelligent Materials Chemistry Group, but we still maintain that old, familiar IMC. Here you can watch our move-themed video.

Kunnallislehti is a local newpaper in the region consisting of Paimio, Sauvo and Kaarina municipalities. Sami was interviewed as a chemist living in Paimio’s Kevola village because of the newly-published X-ray tenebrescence article. Sami tells about the background of the invention, experiences about living in Paimio and also dispels worries that people may have about particle accelerators.
IMC group and our whole chemistry department has received attention from various newspapers and magazines with PhD student Sami Vuori‘s article (corresponding author Adjunct Professor Mika Lastusaari) that was recently published in Advanced Optical Materials: “Detection of X-Ray Doses with Color-Changing Hackmanites: Mechanism and Application“. In addition to showing a practical application, the article also reveals the mechanism of hackmanite’s coloration upon X-ray exposure, which has never been researched thoroughly before.
In the article, Sami imaged a dead body of an ant using a film with hackmanite powder on it. When the X-rays hit the film, the hackmanite colors from natural white to pink, and since the ant’s body attenuates X-rays, some photons are absorbed in it and won’t color the film. This is a simple method, which does not require any expensive analyzers since one can see the result directly.
The article was an international joint effort consisting of researchers from the University of Turku (PhD student Sami Vuori, Adjunct Professor Mika Lastusaari, Dr. Isabella Norrbo, Professor Petriina Paturi, Professor Timo Saarinen and University Teacher Heikki Palonen), University of São Paulo in Brazil (Dr. Lucas C. V. Rodrigues), Karlsruhe Institute of Technology (Dr. Jörg Göttlicher and Dr. Ralph Steininger) and University of Lyon (PhD student Pauline Colinet, Assistant Professor Tangui Le Bahers).
Although this recognition is from last year, yesterday we received this great diploma and the sweets that came with it! Our whole group would like to thank all those who chose us to receive such a tribute. Science is teamwork!
Several years’ worth of active efforts to understand vanadium-catalyzed catechol oxidase mimetic chemistry have finally paid off in full. In our most recent paper, entitled “Vanadium aminophenolates in catechol oxidation: conformity with Finke’s common catalyst hypothesis“, published in the RSC journal Dalton Transactions, and representing the pinnacle of these studies, we have been able to link vanadium-catalyzed catechol oxidase and catechol dioxygenase mimetic studies for the first time. The paper will make a great addition to Pasi’s PhD thesis, especially since the following study gives a nice closure to work already started at the MSc level!
The article, which can be found at doi: 10.1039/d1dt00419k, was so well received by the reviewers and editors, that it was not only added to the HOT article collection at Dalton Transactions, but also granted a place at the Front Cover of the current issue!
Ari, Anssi, Pasi and Åbo Akademi’s project researcher Risto Savela discovered new information about the functionality of vanadium aminophenolates in cathecol oxidation. The article is published in Dalton Transactions and was selected to their HOT article collection. Good job!
Turun Sanomat, the biggest local newspaper in the Turku area, has a popular science-related article series called Aliot. Mika and Ari wrote about inorganic chemistry in a manner that everyday reader can grasp.
