“Protonation and water exchange kinetics in sandwich polyoxometalates”
in Dalton Transactions, 2018, 47, 13602-13607. Link.
Abstract: Density functional theory is used to explore the locus and consequences of protonation in [Zn4(H2O)2(PW9O34)2]10− . The results are used to explain recent observations regarding the contrasting pH effects on the water-ligand exchange in [Mn4(H2O)2(P2W15O56)2]16− and [Co4(H2O)2(P2W15O56)2]16− , and the general effect of protonation on solvent exchange in metal oxides is discussed.

Mark Ramabaran has joined the Ohlin group as a PhD student. He will be looking at the solution chemistry of polyoxometalates and their use as models for reactions on extended metal oxide surfaces.
Merve nailed her Ph.D. Thesis “Thin Water and Films on Minerals: A Molecular Level Study” on March 23rd.
She will defend her thesis on April 13th at Umeå University (info here).
