Abstract: Disclosed are a cis-platinum cross-linked protein hydrogel and a preparation method thereof. Main components of the cis-platinum cross-linked protein hydrogel comprise the following ingredients in percentage by mass: 0.5% to 5.0% drug, 6.0% to 50.0% serum albumin and 47.0% to 93.0% solvent medium; a carboxyl group on a surface of the serum albumin and the drug form a coordinate bond; and the drug is cis-platinum. A hydrogel preparation is simple in structure and easy to prepare, and the used cis-platinum has dual effects: a cross-linking agent for promoting the formation of protein hydrogels and an antitumor drug for exerting a tumor inhibition curative effect. The strategy simplifies the carrier design and reduces potential toxic side effects. The protein carboxyl limits the release of cis-platinum through a coordination effect so that reduce the burst release of the loaded drugs drastically.

Abstract: A method and apparatus for inspecting a wind turbine blade. The method includes: acquiring a sound signal generated by an impingement of wind on the wind turbine blade using a sound acquisition device; generating a frequency spectrogram corresponding to the sound signal; and obtaining a damage recognition result of the wind turbine blade from the frequency spectrogram by performing image recognition on the frequency spectrogram based on a damage recognition model. With the method, a damage type of the wind turbine blade is accurately recognized based on the frequency spectrogram without manual inspection. Therefore, human resources are saved. In addition, the health state of the wind turbine blade can be monitored in real time.

Abstract: Disclosed are a method and apparatus for detecting a yaw-to-wind abnormality. The method includes: acquiring a wind direction deviation angle within a specified time period; calculating a power performance index, wherein the power performance index is a dimensionless number used to characterize power generation performance of a wind turbine; determining an optimal wind direction deviation angle based on the power performance index; determining a current wind direction deviation angle according to probability distribution of the wind direction deviation angle; and if a difference between the optimal wind direction deviation angle and the current wind direction deviation angle is greater than a preset threshold, determining that a yaw-to-wind abnormality is detected.

Abstract: 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.

Abstract: 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.

Abstract: 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.
