Different options for multi-rotor wind turbine grid connection
The Journal of Engineering, 2019 Here, different options for integration of the multi-rotor wind turbine (MRWT) concept are investigated. The intra-turbine collection network of the MRWT can be designed in either AC or DC. The reliability and costs associated with each connection option

Advanced Materials Interfaces, EarlyView.Here, we reported a series of molecular‐rotor‐based photoactivated oxidase mimics, DAPy‐Xm, in which heavy atom incorporation enhances both ROS generation and cold‐adapted property. Among them, DAPy‐Im enables efficient photo‐oxidation of ergosterol and photocatalytic H2O2 production at low temperature.
