Influence of the ligand stripping on the transport properties of nanoparticle-based PbSe nanomaterials
(2020-01-07)
Article
Restricted access - publisher's policyNanomaterials produced from the bottom-up assembly of nanocrystals may incorporate ~1020–1021 cm–3 not fully coordinated surface atoms, i.e., ~1020–1021 cm–3 potential donor or acceptor states that can strongly affect ... -
Critical evaluation of European balancing markets to enable the participation of Demand Aggregators
(2020-04-15)
Article
Restricted access - publisher's policyEuropean Directives are incentivizing consumers to play an active role in the electricity system and to collaborate to maintain its stability, which has been historically provided by large generation power plants. However, ... -
Transition metal oxides for kesterite solar cells developed on transparent substrates

Impedance-Based Modelling of Hybrid AC/DC Grids With Synchronous Generator for Interaction Study and Dynamic Improvement
(Elsevier, 2020)
Article
Restricted access - publisher's policyHybrid AC/DC grids are increasingly been seen as the most important network structure for future transmission infrastructures. An emerging challenge to such grids is the constant interaction between various components in ... -
A non-centralized predictive control strategy for wind farm active power control: A wake-based partitioning approach
(Elsevier, 2020)
Article
Restricted access - publisher's policyOwing to wake effects, the power production of each turbine in a wind farm is highly coupled to the operating conditions of the other turbines. Wind farm control strategies must take into account these couplings and produce ... -
Advanced Impedance-based Control Design for Decoupling Multi-Vendor Converter HVDC Grids
(IEEE, 2020-01-22)
Article
Open AccessA progressive interconnection of existing HVDClinks to form grids and the development of completely new HVDCgrids from different vendors are expected shortly. One of thecurrent challenges of such endeavour ... -
A low temperature solid state reaction to produce hollow MnxFe3-xO4 nanoparticles as anode for lithium-ion batteries
(2019-12-01)
Article
Restricted access - publisher's policyHollow MnxFe3-xO4 nanoparticles (NPs) with an average size of 15¿nm are produced from the solid state reaction of Fe3O4–Mn3O4 heterostructures. These heterostructures are synthesized through the seeded-growth of Mn3O4 ... -
Upscaling high activity oxygen evolution catalysts based on CoFe2O4 nanoparticles supported on nickel foam for power-to-gas electrochemical conversion with energy efficiencies above 80%
(2019-12-15)
Article
Restricted access - publisher's policyWe investigate cobalt ferrite nanoparticles (NPs) supported on large-scale electrodes as oxygen evolution reaction (OER) catalysts. Colloidal CoFe2O4 NPs were loaded on low-cost and high surface area nickel foam (NF) ... -
