  • Publication number: 20240332817
    Abstract: A liquid crystal antenna is provided. The liquid crystal antenna includes a liquid crystal layer, a first substrate, a second substrate, a first connection portion and a second connection portion. The first substrate and the second substrate are located on both sides of the liquid crystal layer in a first direction. The first substrate includes a plurality of first control lines, and the second substrate includes a plurality of second control lines. The first connection portion and the second connection portion are located on the same side edge of the liquid crystal antenna and are staggered in the first direction. The first connection portion is electrically connected to the plurality of first control lines, and the second connection portion is electrically connected to the plurality of second control lines.

  • Patent number: 9499501
    Abstract: The present invention belongs to the technical field of agricultural fungicides and discloses a 2-mercaptobenzothiazole manganese zinc, preparation method therefor and application thereof. The chemical structure of the 2-mercaptobenzothiazole manganese zinc is shown as the above formula. Wherein m, n and n? are positive integers, m=2(n+n?), n?n?, n:n?=1:1˜9:1. Materials are prepared according to the stoichiometric ratio of the target products; 2-mercaptobenzothiazole is dissolved in sodium hydroxide solution. The aqueous solution of water-soluble manganese salts and water-soluble zinc salts solution are successively added to 2-mercaptobenzothiazole sodium solution under stirring, followed by stirring for mixing well, then the solution being allowed to stand, filtered and washed with water to obtain filter cake, and then dried in vacuum to obtain 2-mercaptobenzothiazole manganese zinc. The present 2-mercaptobenzothiazole manganese zinc may be used as an agricultural fungicide.
