Pasi and Anssi make the cover picture for Dalton Transactions!

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!

Press release: scientists (Ari, Anssi, Pasi) discover new information about the function of enzymes

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!

Natural hackmanite paper spreads everywhere

It seems that the natural hackmanite article published in Chemistry of Materials has spread wider than we could ever imagine. It has now been found in 17 different sources from 5 different language regions throughout the world, and there will probably be even more during the coming months.

IMC’s hackmanite research gets country-wide attention in two major newspapers

We wrote a press release based on our hackmanite research article in the high-impact Chemistry of Materials journal. The news was published on University of Turku’s website, and it spread instantly to Finland’s biggest newspaper Helsingin Sanomat and also to a Turku-based newspaper Aamuset:

Congratulations Cecilia and Sami!

The first paper for Cecilia and Sami was just accepted for publication in Chemistry of Materials. The paper is entitled “Hackmanite – the natural glow-in-the-dark material” and it will be published soon in open access.

Great work from Cecilia, Sami and the truly multidisciplinary international collaborator group!
