摘要:
An airfoil 11 for attachment to a hub 13 of a windmill 15 or other turbomachine, the airfoil 11 comprises a leading rod 17 and a trailing rod 27, the leading rod 17 and trailing rod 27 preferably are flexible and able to deflect in a direction opposite to that of the direction of rotation, the leading rod 17 having a first end 19 and a second end 21, the first end 19 secured by a leading rod mount 23 of the hub 13 located at a leading mount location 25, the trailing rod 27 has a base end 29 and a tip end 31, the tip end 31 connected with the second end 21 of the leading rod 17, and the base end 29 secured by a trailing rod mount 33 of the hub 13 located at a trailing mount location 35, and fabric sleeve 37 is stretched over the leading rod 17 and the trailing rod 27; the aerodynamic characteristics of each airfoil are configurable by modifying the orientation of the position/alignment of the leading red 17 relative to the trailing rod 27; and the invention including an assembly of airfoils attached to a hub 13, and a method of harnessing energy using the airfoil 11 of the invention.
摘要:
An electroluminescent device is provided incorporating an emissive layer comprising a processible polymer matrix such as poly(methylmethacrylate) and a chromophoric component such as an asymmetric stilbene or distyrylbenzene. The chromophoric component is blended with the polymer matrix or covalently attached thereto as a side chain and is selected to emit radiation in the region 400 nm to 500 nm when excited to luminesce.

摘要:
An electroluminescent device has at least two active semiconductive conjugated polymer light emitting layers arranged between a cathode and an anode. The layers are arranged so that at least part of at least two layers lie in an emission zone of the device.
摘要:
In an electroluminescent device which comprises a layer of a semiconductive conjugated polymer between positive and negative charge carrier injecting electrodes, a barrier layer is arranged between the layer of semiconductive conjugated polymer and the charge carrier injecting layer for negative charge carriers. The barrier layer protects the layer of semiconductive conjugated polymer from for example mobile ions released by the reactive charge carrier injecting layer. The barrier layer can in some circumstances also itself be light-emissive.
