The invention discloses a method for preparing lithium ion sieve-type adsorbent particles used for extracting liquid lithium resources such as salt lake brine, seawater, and groundwater. The adsorbent particles use water-absorbing polymers as carriers, and add lithium-ion sieve-type adsorbents such as metatitanic acid-type Li 2 TiO 3 , spinel Li 4 Ti 5 o 12 , spinel Li 1.6 mn 1.6 o 4 , spinel LiMn 2 o 4 etc., and are prepared by secondary cross-linking. The preparation process is simple and suitable for industrial production. The prepared adsorbent particles have the characteristics of high elasticity, porosity, high water absorption and good permeability. The resin matrix is ​​resistant to strong acids and alkalis, and the polyhydroxyl structure on the surface of the matrix can effectively absorb adsorbent particles and effectively reduce the rate of dissolution loss. Corroded substrates are suitable for industrial adsorption column processes.

The invention provides a transistor, a display substrate, a display device and a manufacturing method thereof, and belongs to the field of semiconductors. The transistor comprises a semiconductor structure; the semiconductor structure comprises: a source region, a drain region, a channel region and a capture region, wherein the channel region is located between the source region and the drain region and is constructed as a carrier migration passage between the source region and the drain region in the on-state of the transistor; and the capture region is at least partially embedded in the channel region and is constructed to capture carriers migrating between the source region and the drain region in the off-state of the transistor. Based on the design of embedding the capture region intothe channel region, in the invention, the migration carrier of the off-state leakage current can be restrained by using the capture region, thus the off-state leakage current of the transistor can bereduced, and the performance of relevant devices and products is enhanced.

The invention discloses an efficient calcium-loaded surimi product and a preparation method thereof.The efficient calcium-loaded surimi product comprises surimi, fish bones and plant polyphenols, the plant polyphenols serve as a calcium modifier, Ca-coated polypheol particles with certain reaction activity are obtained, and calcium loading can be enhanced. According to the method disclosed by the invention, fish bone calcium is wrapped in a surimi gel system on the basis of a hydrogen bond bridging effect between polyphenol phenolic hydroxyl groups and myofibrillar protein amino groups, so that effective intake of calcium is enhanced, and calcium loss in a high-temperature processing process is reduced. The polyphenol not only can be used as a calcium modifier to play a binding role of nano calcium, but also can be used as a quality modifier to further enhance the processing and storage quality of the surimi product due to rich biological activity and antioxidant activity.
