Facing seawater splitting challenges by regeneration with Ni-Mo-Fe bifunctional electrocatalyst for hydrogen and oxygen evolution
(2021-07-22)
Article
Restricted access - publisher's policyHydrogen, produced by water splitting, has been proposed as one of the main green energy vectors of the future if produced from renewable energy sources. However, to substitute fossil fuels, large amounts of pure water are ... -
End of electric vehicle batteries: reuse vs. recycle
(2021-04-16)
Article
Open AccessIt is a fact that electric vehicles (EVs) are beneficial for climate protection. However, the current challenge is to decide on whether to reuse an EV battery or to recycle it after its first use. This paper theoretically ... -
Defect depth-profiling in kesterite absorber by means of chemical etching and surface analysis
(2021-02-28)
Article
Restricted access - publisher's policyA method to probe the depth morphology, defect profile and possible secondary phases in a thin film semiconductor is presented, taking a standard Kesterite film as an example. Using a top-down approach based on a previously ... -
