The Effect of Voltage Cycling on Catalyst Degradation in Automotive PEM Fuel Cells
(Universität Ulm, 2019-04-11)
Durability and cost are the two major remaining challenges for the commercialization of fuel cells in passenger vehicles. The platinum catalyst is one of the most expensive components in a fuel cell and degrades during ...
Thiomolybdate clusters: active site models for the light-driven hydrogen evolution reaction
(Universität Ulm, 2018)
Polyoxometalate-based nanocarbon composite materials as lithium ion battery electrodes
(Universität Ulm, 2019-02-13)
Nowadays, a dependence on coal, oil and natural gas has created severe air pollution and global warming with alarming consequences. Solar energy, wind power, nuclear energy, as well as geothermal energy represent sustainable ...
Nanostructured Ni(OH)2 and MnO2 cathode designs for aqueous asymmetric double layer capacitors
(Universität Ulm, 2019-04-29)
The roles of the current collectors in electrode fabrication and designs for electrochemical energy storage devices have become increasingly important. Ni based current collectors have been deployed in aqueous-alkaline ...
Surface-enhanced infrared attenuated total reflection spectroscopy based on carbon nanomaterials
(Universität Ulm, 2019-08-05)
This cumulative dissertation focuses on studying the potential of carbon nanomaterials in surface-enhanced infrared absorption (SEIRA) spectroscopy, which is based on four peer-reviewed journal articles. The introduction ...
