Abstract: A photoelectric sensor includes: a substrate with a light-receiving surface. The substrate includes a photosensitive pixel area and the photosensitive pixel area includes pixel unit areas distributed in a matrix. Light traps are located in a part of a thickness of the substrate in the pixel unit area. The light traps are located on the light-receiving surface of the substrate, and distributed in a matrix along a row direction and a column direction. The row direction is perpendicular to the column direction. Adjacent light traps in the column direction are connected, and adjacent light traps in the row direction are connected. Side walls of the plurality of light traps surround and form a plurality of protrusions. Adjacent protrusions are connected, and the plurality of protrusions has a shape of octagonal pyramid.

Abstract: A photoelectric sensor and a method for forming same and an electronic device are provided. The photoelectric sensor includes: a base, having a light receiving surface and including a pixel unit region; and a plurality of light trapping grooves, arranged in a part of the base in a thickness direction in the pixel unit region and arranged on a side of the light receiving surface of the base, where a surface shape of each of the light trapping grooves is arcuate. The present disclosure helps improve photosensitive performance of the photoelectric sensor.

Abstract: The disclosure relates to the technical field of sterilizing and disinfecting materials, and specifically relates to an ?-substituted phenyl structure-containing compound, a preparation method thereof, and a disinfectant. The ?-substituted phenyl structure-containing compound according to the disclosure could achieve a bactericidal effect by promoting the coagulation and denaturation of the protein of pathogenic microorganisms. In particular, it has a good killing effect on pathogenic bacteria such as Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, and Bacillus subtilis var. niger spores. Besides, it has no corrosive effect on metals, no irritating odor, good water solubility, and is green and environmentally friendly. Therefore, it could be widely used in various industries as an effective ingredient of a disinfectant.

Abstract: The present invention discloses a method for channel decoupling of a whole-roller flatness meter for a cold-rolled strip. The method includes the following steps: 1, setting a channel number and a channel breadth of the flatness meter; 2, obtaining an influence matrix under the condition of coupled channels; 3, calculating an inverse matrix of the influence matrix; 4, decoupling the channel by the inverse matrix of the influence matrix; and 5, obtaining flatness distribution after channel decoupling. The present invention decouples the channel of the whole-roller flatness meter by inverting the influence matrix and multiplying with the detection force vector. The present invention reproduces the true force vector and flatness distribution, and provides a new method for improving the flatness detection accuracy.

Abstract: The present invention relates to the preparation of anti-tumor drugs with andrographolide derivatives, which belongs to the field of pharmaceutical technology, and involves 15-benzylidene substituted derivatives of 14-deoxy-11,12-didehydro-andrographolide and their 3,19-ester derivatives. Proved by the experiments, these compounds significantly inhibited the colony formation and migration ability of various cancer cells, and also inhibited the migration ability of vascular endothelial cells in vitro. The compounds of this invention significantly inhibited the tumor growth, invasion, metastasis and angiogenesis on mouse xenograft models, and inhibited the experimental lung metastasis of B16-F10 malignant melanoma cells. Therefore, this class of compounds could be used as the active ingredients for the preparation of antineoplastic drugs, which are of efficiency and low-toxicity.

Abstract: Disclosed is a use of C15-substituted andrographolide derivatives in preparation of anti-hepatitis B virus medicaments. In the present invention, the HepG2.2.15 cells are used to measure the amount of the hepatitis B virus surface antigen (HBsAg) secretion in the supernatant of the culture; the duck hepatitis B virus (DHBV) is used to infect the model and the DHBV-DNA level in serum is measured, and the pathological change in hepatic tissue is observed. A number of andrographolide derivative compounds are screened, compounds having a good anti-HBV effect are preferred, which has a structure represented by general formula 1 set forth herein. Due to high anti-HBV activity and low toxicity, as well as good protection against hepatic injury, the compounds can be used as the active ingredient for preparing anti-HBV medicaments, thereby providing a new pharmaceutical way for treatment of hepatitis, and broadening the range of clinical medicines.
