Light Switchable Ionic Conductivity of Arylazopyrazole Modified Polysiloxanes

open access: yesAdvanced Materials Technologies, EarlyView.
We present a polysiloxane functionalized with a novel arylazopyrazole dye that undergoes reversible photoisomerization. Upon lithium bis(trifluoromethanesulfonyl)imide addition and UV irradiation, the polymer exhibits a shift in tan(d) toward higher frequencies and enhanced ionic conductivity.

Enhanced-Pumped-Storage: Combining pumped-storage in a yearly storage cycle with dams in cascade in Brazil

Energy, 2014
The new frontier for hydropower electricity generation in Brazil, the Amazon region, cannot be used for energy storage as the construction of storage reservoirs would have deep environmental and social impacts, thus run-of-the-river dams have been built instead. If Brazil still wants to generate 80% of its electricity from hydropower, there is the need

Levelised Cost of Storage for Pumped Heat Energy Storage in comparison with other energy storage technologies

open access: yesEnergy Conversion and Management, 2017
Future electricity systems which plan to use large proportions of intermittent (e.g. wind, solar or tidal generation) or inflexible (e.g. nuclear, coal, etc.) electricity generation sources require an increasing scale-up of energy storage to match the ...

Nanocapsule with pump for methane storage

Physical Chemistry Chemical Physics, 2011
A nanocapsule for high-effective methane storage is investigated using molecular dynamics simulation. Methane molecules are pumped into a nanocapsule via pumping and locking chambers by the K@C(60)(1+) ions moved by the electric field. When such a technique is used, the methane weight content in the nanocapsule reaches 36.4 wt%.
