Advanced Engineering Materials, EarlyView.The tribological behavior of 100Cr6 steel spheres textured via Vickers microindentation is evaluated under lubricated sliding by varying both dimple size and density. Fine and dense textures significantly reduce friction across all lubrication regimes, while large dimples increase it.

Three-Phase Embedded Modified-Z-Source Three-Level T-Type Inverters
IEEE Access, 2020 Two topologies are designed by combining a modified-Z-source (MZS) network consisting of three diodes, two inductors and four capacitors to a traditional three-level T-type inverter (3LTI), and embedding either one or two dc sources in the impedance ...
