New paper published in Nature Communications on parameters determining charge storage mechanisms in nanoporous supercapacitors
To improve the performance of supercapacitors, a mechanistic understanding of ion electrosorption is required. In this work we identify parameters like salt concentration, charging velocity or cell design, controlling mechanisms of ion charge storage. Moreover, we show that charging initially leads to a non-equilibrium ion configuration even at extremely low cycling speed, followed by an increase of the total ion concentration, i.e. a charge-neutral equilibration.
New paper published in Nanoscale reveals peculiar nano-mechanics of the van der Waals interface between organic nanostructures and 2D materials
Self-assembled and self-alligned organic nanostructures are very interesting building blocks for the future nanoelectromechanics, especially considering an increasing demand to improve, miniaturize, and integrate various sensors into low-power wearable (flexible) applications. Unique nanomechanics that exists on these scales might appear as counter-intuitive in a macroscopic world, and therefore understanding of the underlying mechanisms is a key step in advancement of these technologies.
The impact of the paper on "3D colloidal supercrystals" is further illustrated by the fact that is was selected as Inside Front Cover in Volume 30, Issue 32, August 9, 2018 of Advanced Materials
In this study three Austrian Universities the TU Graz, the Univ. Wien led by the MU Leoben worked together to reveal the supercrystal structure of free standing 3D colloidal supercrystals by combining in-situ synchrotron SAXS experiments at ELETTRA with simulations.

In a recently published article in Scientific Reports a method to reconstruct the piezoelectric domain orientation distribution function of device-ready polycrystalline lead zirconate titanate (PZT) is presented.
For his important contribution to the understanding of ion behavior in supercapacitors, Dr. Christian Prehal was awarded with the Fonda-Fasella prize.
