January 11, 2017 - Cover Nano Letters

Our recent paper on nanowire-based sensors for the detection of TNT has reached the cover of the first 2017 issue of Nano Letters.





December 8, 2016 - Poster Prize Laura @ IMSTEC 2016

Laura Paltrinieri won the Best Poster Presentation Prize for her contribution on 'Phosphate transport through anion exchange membranes: effect of salt concentration and type of co-ion' at the 9th International Membrane Science and Technology Conference in Adelaide, Australia. Congrats Laura!

November 24, 2016 - E-motion Started!

This month the ERC Consolidator program on the Electro-motion for the recovery of nutrients started. Nathalja Berghuis started as a PhD student. See also the WUR magazine, Resource (English or Dutch) and Waterforum.

November 9, 2016 - MOPs for TNT Sensing

Our latest paper appeared online today in Nano Letters. [doi] The work describes nanowire-based sensors which can detect trace amounts of TNT, an explosive compound, by using a lantern-type cage structure. These so-called metal−organic polyhedra (MOPs) act as a host for TNT. The work was performed in close collaboration with the University of Twente, Philips Research, the City University of Hong Kong and the University of Melbourne. Congrats to first authors Anping and Wei!
