The ambition of the OScAR project is to facilitate future commercial development of Na-ion batteries (NIBs) for stationary energy storage by establishing a fundamental understanding of a family of Sn-based anode materials capable of boosting the capacity of existing NIBs.
In-situ TEM experiments shows that the tendency for elemental mixing- or segregation to occur in Pt–Rh nanoparticles depends on the nanoparticle size and temperature. The smaller nanoparticles (≲13 nm) are stable in the solid solution configuration over the entire studied temperature range. Larger nanoparticles (≳13 nm) tends to segregate when cooled to room temperature. The results are of importance to understand the thermodynamics of this specific Pt–Rh nanoparticle system and it add value towards applications like catalysis, whereof e.g. supported Pt–Rh nanoparticles are attractive candidates for NH3 slip abatement processes.
If one collects all the solar irradiation flowing towards the Earth in one hour, one will have enough energy to meet the world’s consumption in one year. Practically, however, one is dependent on efficient energy storage options, to compensate for daily and seasonal variation in solar irradiation. The same goes for other renewable energy sources such as wind power.
