Tools for nano scientists Particle characterization of energy storage materials with analytical centrifugation on the way to a successful energy transition
CENIDE is a research center representing the main research area "Nanoscience" of the
University of Duisburg-Essen. The experience of more than 85 working groups spreads
across our six research areas [1].
This year, CENIDE is once again honouring young researchers with the “CENIDE Best Paper
Award”. The nominated papers must be published in an international peer-reviewed journal
in 2023 or 2024 and must not have already been awarded the “CENIDE Best Paper Award”
[2].
The paper "Key Control Characteristics of Carbon Black Materials for Fuel Cells and Batteries
for a Standardized Characterization of Surface Properties" by Amin Said Amin et al.,
published as open access in Particle and Particle Systems Characterization, (Early View), [3],
won the CENIDE Best Paper Award 2024. LUM GmbH warmly congratulates.
First author Amin presented partial results in June at the International Conference for
Dispersion Analysis & Materials Testing (ICDAMT 2024, Berlin) and was honoured there as
the best young scientist with the Young Scientist Award 2024 from LUM GmbH [4].
The Key Control Characteristics (KCCs) include physicochemical features like electrical
conductivity (electron transport through the catalyst layer, CL), oxygen-containing surface
groups (hydrophilicity/hydrophobicity of the CL, catalyst functionalization), surface
basicity/acidity, ionomer adsorption, and particle dispersibility (catalyst ink stability). KCCs
are determined by particle bulk electrical conductivity, Boehm titration (BT), isoelectric
point (IEP), and Hansen solubility parameters (HSP). HSP, understood as similarity
parameters for particles, indicate how nanoparticle surfaces interact with liquids during
dispersion. The proposed KCCs serve as a starting point for characterizing CBs and guiding
product design to obtain meaningful structure-property relationships, essential for a
successful energy transition [3].
In the award-winning publication, the authors illustrate the potential and successful
application of analytical centrifugation for particle surface characterization (HSP
determination), technically implemented in the LUMiSizer® dispersion analyser. The results
are an important basis for a current standardization project within the International
Electrotechnical Commission IEC/TC 113 (Nanotechnology for electrotechnical products
and systems) [5].
