Impact of individuals and their competences on change processes in sport organisations Open
When it comes to changes in voluntary sport organisations, the members play a key role in initiating and implementing change processes. The capacity of an organisation to change depends at least partially on the individuals’ change compete…

Healthy working in inclusive companies – a study protocol of the GAIN project Open
Background The research project GAIN (working healthy in inclusion companies) deals with the topics of health and work in inclusive companies. Due to a great need for research on (occupational) health (e.g. physical and mental health statu…

Antisemitism as a football specific problem? The situation of Jewish clubs in German amateur sport Open
Despite the undisputed existence of antisemitic incidents in sport, little is known about their exact prevalence and forms of manifestation. Also in Germany, physical and verbal attacks against Jewish sports clubs have repeatedly come to l…

Visualization of Local Ionic Concentration and Diffusion Constants Using a Tailored Electrochemical Strain Microscopy Method Open
A tailored electrochemical strain microscopy technique is presented and used to analyze the ionic mobility and diffusion coefficients in composite Si/C anodes. The resulting surface displacement after a voltage pulse is proportional to the…

Design-Considerations regarding Silicon/Graphite and Tin/Graphite Composite Electrodes for Lithium-Ion Batteries Open
An analytical model is proposed to investigate properties of composite electrodes that utilize more than one active material. We demonstrate how the equations can be applied to aid in the design of electrodes by comparing silicon-graphite …

Development of Tests for Lithium-Ion Cell Characterization Open
The long-term degradation behavior of lithium-ion batteries is directly related to changes in the internal resistance of the cells. Reasons for the increase in resistance are i.e. growth of insulating surface layers, electrolyte decomposit…
