Physical Chemistry of Nanoscale Systems

Welcome to the website of Prof. Kappes´research unit "Physical Chemistry of Nanoscale Systems" at the Insitute of Nanotechnology within the Karlsruhe Institute of Technology.

Our research contributes to the Helmholtz funded  topics "Functional Molecules", "Carbon-based Nanostructures" and "Nanomaterials and Nanocatalysis"

For a detailed description of our current research activites at the INT please have a look at our research pages. For more information on the activities on KIT Campus South see also: Institute of Physical Chemistry



Carbon nanotubes for high-density, short-channel transistors

 Highly enriched samples of semiconducting single walled carbon nanotubes have been prepared by combining polymer-wrapping with size-exclusion chromatography. Using this SWCNTs short-channel transistors were built showing the best performance published so far. More see ACS Nano, Article ASAP.

Structural evolution of ruthenium clusters

A combination of trapped ion electron diffraction measurements and DFT computations reveal the structural evolution of small ruthenium clusters in the size range of n=4-20.

Separation of Nanotubes
Separation of Double-Walled Carbon Nanotubes

Using size exclusion chromatography we separation raw carbon nanotube material into fractions of double-walled and single-walled carbon nanotubes. The presented technique is easily scalable and offers an alternative to traditional density gradient ultracentrifugation methods.

Oxygen affinity of iron porphyrin molecules revealed

Using gas-phase ion chemistry the binding energy of molecular oxygen and carbon monoxide to heme analogue iron(II)porphyrin anions has been determined.
