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:

Tutkijat selvittivät, miksi luonnonkivi loistaa pimeässä – Hackmaniitin ytimessä hehkuu titaaniHelsingin Sanomat 23/10/2020

Pimeässä loistavan luonnonkiven salaisuus selvisi tuoreessa tutkimuksessaAamuset 23/10/2020

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!
