Sapphire-supported water films: Paper with PNNL collaborators just accepted in JCIS

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:

Water vapour condensation paper out now in ES&T

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.

 

 

 

Paper on protonation in Anderson-type POMs published in Inorganic Chemistry

Direct Single- and Double-Side Triol-Functionalization of the Mixed Type Anderson Polyoxotungstate [Cr(OH)3W6O21]6–”

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.
