Public outreach lecture about chemistry

As a public outreach, Adj. Prof. Mika Lastusaari had a presentation about chemistry in one of Turku Teacher Training School’s IB line’s Integrated Science course visitor lectures. Hannah and Sami also got to tell why they have come to study chemistry and what inspires them, and also demonstrated color change and afterglow with the compulsory praise for inorganic chemistry! The “set” is shown in the photos.

Gathering for Pasi’s research visit to Austria

Yesterday Pasi Salonen held a small gathering for his last day before leaving for a research visit to Graz, Austria. Pasi is confident to gather vital data for his PhD thesis and was, as many members of the team, especially excited to go to the place where Arnold Schwarzenegger is from. We wish him a pleasant stay in Graz, and as Pasi himself stated, we’ll see in no time! Hasta la vista!

GlowTrack kickoff meeting in Tampere

On Friday, Jan 10, 2020 we held the kickoff meeting for the Academy of Finland-funded GlowTrack project in the beautiful city of Tampere. We were warmly welcomed by the people of Tampere University: we had a tour in the laboratory facilities, discussed about ice hockey and had a mutual agreement on how to proceed with the project. We will eagerly be executing it in collaboration with the Tampere team.
