Hybrid Power Filter Based on a Six-Switch Two-Leg Inverter

Eletrônica de Potência, 2014
Hybrid power filters (HPFs) are considered an attractive solution to overcome the problem of current harmonics generated by nonlinear loads. They mix low power rating active filters with passive filters, but many of these HPF topologies have a great ...

Copper Nanocrystallization in Anodic Oxide Films of Ti–Cu‐Based Bulk Metallic Glass and Its Effect on the Corrosion Resistance and Cytocompatibility

Advanced Engineering Materials, EarlyView.
Viktoriia Shtefan, Thorgund Nemec, Ute Hempel, Annett Gebert and coworkers demonstrate that anodic treatment of Ti–Cu‐based metallic glass in a nontoxic pyrophosphate electrolyte forms a protective bilayered Ti/Zr‐oxide film enriched with Cu nanocrystals.
