Copper surfaces influence the growth of copper oxide nanowires

Scientists of the Material Center Leoben, the Department of Material Physics of the Montanuniversitaet Leoben, and Gerhard Popovski of the Institute of Physics have shown that different copper surfaces will influence the growth of copper oxide nanowires. Small copper grains and high surface roughness promote the growth of these important structures, which are used for example in solar cells or sensors.

The Shape of Nanocrystals Influences their Optical Performance: Revealed in an open access article in Frontiers of Chemistry

Scientists from the Institute of Physics together with colleagues of the ETH Zürich as well as the ESRF in Grenoble showed recently that the crystal structure of core/shell CdSe/CdS nanocrystals (3.5 -14 nm) influences the particle shape. The particle shape again directly influences the photoluminescence (PL) quantum yield: The “larger”, strongly faceted nanocrystals with dimensions of up to 14 nm and aspect ratios of around 1.7 show the lowest PL output. These results were only possible with combined scattering (anomalous SAXS) and diffraction (WAXS) experiments at the synchrotron ESRF.

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.
