Molecular Geochemistry at Umeå University
connecting atoms with mountains
Emma Westling, Lisa Bryggman and Niklas Viklund from Nolaskolan in Örnsköldsvik brought in soil samples for Cesium-137 analysis. Many thanks to Peder Arvidsson from the University Hospital of Umeå (Center for medical technique and radiation physics) for providing access to his laboratory and hosting the students.
The study is a collaboration with the group of Khalil Hanna (Rennes University)

In collaboration with Hongfei Wang (Fudan University) and other current and former Pacific Northwest National Laboratory scientists, we used Sum Frequency Generation Vibrational Spectroscopy (SFG-VS) and molecular model to provide new insight on the orientation and hydrogen bond populations of nanometric water films on sapphire (alpha-Al2O3) surfaces:
Congratulations Merve Yesilbas for receiving the prestigious NASA Postdoctoral Program (NPP) Fellowship. Merve will use this fellowship, alongside a postdoctoral grant from the Swedish Research Council, to join the NASA Astrobiology Program
Tan is beginning his Ph.D. studies with Jean-François Boily. He will be working on (photo)catalytic reactions at Mn-bearing mineral surfaces.
A multi-institution collaboration involving University of Wyoming, Argonne National Laboratory, Canadian Light Source, Stony Brook University and Huazhong Agricultural University.

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.
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.
