In view of this, we present an investigation of the lithium-oxide phases that are generated during the operation of Li–O2 batteries, which use LiTFSI/tetraglyme as the

On the way to commercialization, however, this promising type of PEFC still faces several problems concerning its long term stability and the overall efficiency of electrode and membrane materials. These properties should be further

Investigations of nanoscaled photovoltaic devices require nanometer-scale measuring methods, including time-resolved measurements of the carrier dynamics [15][16

A general review of materials aspects in nanotechnology-based approaches in energy technology can be found in [8]. From the

The remarkable stability for more than 1.5 years under ambient air without any observable changes can be attributed to self-passivation. After

We demonstrate that the technique of AFM-tip-induced mechano-electrochemical writing is fully reversible, and we investigate the long-term stability of the resulting

• key feature for the technological relevance and application perspectives of electrochemically deposited nanostructures is their long-term stability. The nanostructures have to remain stable under ambient air after being taken out of the electrolyte. To study the long-term stability of
