Boily's group (http://moleculargeo.chem.umu.se/) and we published a new paper in PNAS

Ice can play a critical role in enhancing soluble iron production in frozen environments. This research elucidates the effects of freezing temperature, salinity, organic loadings, and freeze-thaw cycling on the dissolution of an important nanomineral of the iron oxide family. It provides kinetic and mechanistic insights into ice-driven dissolution reactions in acidic ice, and it identifies conditions under which ice solubilizes more iron than in liquid water.

Dr. Tao Chen's PhD defense

Tao Chen successfully defended his PhD thesis on “Environmental Ice-Driven Reactions of Mn and Fe Species” on November 26, 2024. The thesis was jointly supervised by K. Hanna (ISCR, Rennes University) and J.F. Boily (Umeå University, Sweden).

International Research Project CHEMICY workshop

With the University of Umeå and the Rennes Institute of Chemical Sciences (ISCR), our lab organized the second workshop of the IRP- CHEMICY. It was held on November 27, 2024 at the Ecole Nationale Supérieure de Chimie de Rennes (ENSCR), 11 allée de Beaulieu in Rennes (France).

The purpose of this workshop was to stimulate the communication between researchers from both sides and facilitate the exchange of opinions and common interests. It was open to all scientists interested in impacts of freeze-thaw cycles and environmental implications.
