Abstract: A blade for a rotor of a wind turbine, the blade comprising: an inboard portion; an outboard portion connected to the inboard portion, wherein the outboard portion is deflectable by a variable sweep angle in an edgewise direction of the blade; and a passive mechanism configured to adjust the sweep angle in response to an amount of flapwise moment acting on the blade, such that the magnitude of the sweep angle increases in response to an increased flapwise moment, and decreases in response to a decreased flapwise moment.

Abstract: Biodegradable drinking straws from date palm leaves as a substitute for plastic straws. The straws are made by washing the palm tree leaves with a solution of ascorbic acid, 99% ethanol and water, cleaning the palm tree leaves with abrasive sheets, soaking the palm tree leaves, drying the palm tree leaves, heating the palm tree leaves to a temperature selected from a range of 60° C. to 140° C., rolling the palm tree leaves, binding the rolled palm tree leaves using biodegradable food grade adhesive, drying the rolled palm tree leaves.

Abstract: A novel hybrid non-alcoholic solvent solution and fabric for antimicrobial applications provides a non-toxic, economical, biodegradable, anti-microbial solution, that not only inhibits the growth but also kills microbial pathogens. In certain embodiments, the hybrid solvent composition includes extracts of curcumin, Syzygium aromaticum, Azadirachta indica, Trachyspermum Ammi, Cinnamomum Camphora, Cinnamomum Verum, and Elettaria Cardamomum.

Abstract: The twist morphing blade for wind turbine is a blade adapted for attachment to the hub of a wind turbine. The blade has a central shaft extending between the root and tip ends of the blade. A guide track is defined in the central shaft. A sliding mass is slidably disposed in the guide track and bears against a bias spring. A driven shaft is coaxially disposed around the sliding mass and bias spring and rotatably coupled to the sliding mass. Connecting rods extend between the driven shaft and root end of the blade and through active and passive ribs alternately spaced between the driven shaft and the root end of the blade. When incident wind rotates the rotor, centrifugal force linearly slides the mass, which rotates the driven shaft and the connecting rods to deflect the ribs, twist morphing the medial sections of the blade.
