摘要:
An electrochemical method for producing a hole extraction layer in a solar cell based on organic semiconductor materials. Conjugated polymers are used to build a hole extraction layer and a photoactive layer. Poly(3,4-ethylenedioxythiophene) (PEDOT) is used as a hole extraction layer and is deposited electrochemically from an aqueous solution on an indium tin oxide (ITO) electrode. A nanofibrilar or nanogranular morphology of the PEDOT is achieved by carrying out the polymerization in the presence of a surfactant. A photoactive layer of poly(3-hexylthiophene)/[6,6]-phenyl-C61-butyric acid methyl ester (P3HT/PCBM) can be deposited by spin-coating technique on top of the PEDOT layer.

摘要:
The invention provides a method for identifying volatile insect repellents and/or attractants released from their non-volatile glycosides by the action of -glucosidase on plant tissue extracts. By this method, geraniol was identified as codling moth repellent and methyl salicylate, (2R,5R)-theaspirane, and (2S,5R)-theaspirane, and to a lesser extent linalool and benzyl alcohol as codling moth attractants. The invention provides compositions comprising said repellent and attractants and methods for control of codling moth in fruit, preferably apple, orchards.
摘要:
A terminal pliers structure includes a seat, a drive mechanism, and a clamping mechanism. The clamping mechanism includes a first clamping block, a second clamping block, and a spring. In operation, the first clamping block and the second clamping block are forced to pivot in concert with each other, thereby facilitating the user operating the terminal pliers structure, and thereby saving the manual work. In addition, the first teeth of the first clamping block mesh with the second teeth of the second clamping block to enhance the clamping force between the first clamping block and the second clamping block, so that the clamped terminal head can be clamped between the first clamping block and the second clamping block rigidly and stably.
