Design and evaluation of an energy storage system for helicopters
This paper presents the design and evaluation of an energy storage system (ESS) for helicopters with the aim to recover the kinetic energy in the rotor available after landing and to be able to control the 270 V DC bus voltage during load disturbances. A

High-frequency current source converter for a direct drive powertrain in a wave energy converter
Wave energy converters (WECs) generally use a mechanical solution such as hydraulics or gearing to optimise the extraction of energy from the incoming waves prior to converting it into electrical energy via a high-speed rotating generator.

Water molecules on the liquid superlubricity interfaces achieved by phosphoric acid solution
The superlubricity mechanism of phospholipid molecules on biological surfaces and interfaces has been receiving much attention. Since the superlubricity can be achieved with a phosphoric acid aqueous solution, the interaction of the phosphate group with ...

Enhanced thermal conductivity of epoxy composites with core-shell SiC@SiO(2) nanowires
Electronic packaging materials and thermal interface materials (TIMs) are widely used in thermal management. In this study, the epoxy composites with core-shell structure SiC@SiO(2) nanowires (SiC@SiO(2) NWs) as fillers could effectively enhance the ...
