A series of bi-directional horizontal axis tidal turbine (HATT) rotors was prototyped. The geometry and motion parameters of the turbine series cover a wide range of tidal turbine operating conditions targeted to the tidal flow speed probability distribution of the Bay of Fundy, NS Canada. A...

Poly (ethylene glycol) (PEG)/silsesquioxane composite was prepared by in situ sol–gel process. The structure of composite was characterized by solid state 31P and 29Si nuclear magnetic resonance (NMR) and Fourier transform infrared spectroscopy (FT-IR). N2 adsorption–desorption measurement...
