A paper (link here) by Wei Cheng & Khalil Hanna (École Nationale Supérieure de Chimie, Rennes, France) and J.-F. Boily. We show that low loadings of organic matter on minerals make surfaces more hydrophobic while high loading make surfaces more
hydrophilic. This work is one of the several to be published from Wei’s 6-month visit in Umeå in March-September 2018.

Abstract: Since the first successful triol-functionalization of the Anderson polyoxometalates, the protons of the central octahedron X(OH)6 (X—heteroatom) have been considered as a prerequisite for their functionalization and therefore the functionalization of Anderson structures from the unprotonated sides have never been reported. Herein, for the first time, we organically functionalized the mixed-type Anderson polyoxometalate with real-time observation of hybrid anion formation.
A recent collaborative venture by the Boily group in the study of pine root respiration with the Näsholm group at SLU. The paper “Improved in vivo measurement of alternative oxidase respiration in Field‐Collected pine roots” is now available in Physiologia Plantarum
Congratulations Merve Yesilbas for a 3 MSEK Postdoctoral Research Grant from the Swedish Research Council! Merve will be using these funds to pursue her research career with Dr. Janice Bishop of the SETI institute in San Francisco to work on the mineralogy of planet Mars.
The Boily group thanks the Kempe foundation for a 2-year extension to our Isotope Ratio Mass Spectrometry work, with group member Dmitry Shevela, on carbon isotopic signatures in minerals.

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.
Many of us in Molecular Geochemistry participated to the Gaussian
workshop at HPC2N on May 14-15!
