Abstract: A meshed catalyst based high-yield preparation and regeneration method for carbon nanotubes and hydrogen includes the following steps: step one, adding waste plastic into a low-temperature pyrolysis section, conducting slow heating, and continuously introducing nitrogen; step two, using a multilayer stainless steel mesh obtained through laminated pressing and vacuum sintering as a catalyst, introducing the volatiles into a high-temperature catalytic section, conducting a catalytic reaction under the action of a meshed stainless steel catalyst obtained through acid etching and calcination pretreatment, generating the carbon nanotubes on a surface of the catalyst, and meanwhile generating high-purity hydrogen; and step three, after temperature drop, conducting ultrasonic treatment on a stainless steel mesh after the reaction, achieving physical stripping of the carbon nanotubes from the stainless steel mesh, then placing the stainless steel mesh subjected to secondary calcination in a system for recycling, and

Abstract: Provided are a boron-silicon heterocyclic compound having a structure represented by formula 1, a display device and a display apparatus. In formula 1, L1 and L2 are each a single bond, C6-C30 arylene, C6-C30 fused arylene, C4-C30 heteroarylene, or C4-C30 fused heteroarylene; D1 and D2 are each a substituted or unsubstituted C6-C60 aryl, a substituted or unsubstituted C4-C60 heteroaryl, a substituted or unsubstituted C10-C60 fused aryl, a substituted or unsubstituted C8-C30 fused heteroaryl, or a substituted or unsubstituted diphenylamino. The compound has a strong inductive effect and can reduce the driving voltage of the device. The silacyclopentadiene having a silicon atom as spiro-atom can effectively improve the solubility of the material, which is beneficial to the cleaning of the vapor deposition mask. In addition, the compound has a higher triplet energy level to effectively transfer energy to the luminous body, and improves the efficiency of the device.

Abstract: The invention belongs to the field of genetic engineering technology and application thereof, and in order to solve the problems of lack of high efficient TMV-resistant RNAi nano-preparation at present, complicated preparation process of medicament, poor stability and delivery efficiency of dsRNA, the invention provides an RNAi nano-preparation, preparation method thereof and application thereof in TMV prevention and control. The RNAi nano-preparation is prepared from dsRNA and chitosan nano materials, wherein, dsRNA is a highly TMV-resistant RdRP3 gene with a length of 313 bp obtained from screening, with nucleotide sequence shown in SEQ ID NO.1, and the volume ratio of the chitosan to 1 ?g/?l dsRNA is 10:(1-6).

Abstract: The present invention belongs to the technical field of application of microbial secondary metabolites, and particularly relates to novel use of prodigiosin in resisting potato virus Y. Application of prodigiosin in preparing a medicine for preventing and controlling potato virus Y. The medicine for preventing and controlling the potyvirus is a liquid or solid preparation containing prodigiosin. It is clarified that PVY promotes its own replication and infection by recruiting host factor Hsp70 in the process of infecting the host, realizing virus infection and spread. Hsp70 plays an important role in the infection and replication of plant viruses. Based on the above results, it is further clarified that prodigiosin treatment can significantly increase the ubiquitination level of the plant host, promote the ubiquitination of HSP70 protein of the host, degrade or inhibit the expression of Hsp70 protein, activate the natural immune activity of the host plant.

Abstract: A method for preparing a solid Trichoderma seed from direct fermentation of crop straws with Trichoderma, and a product prepared by using the same. The method includes adding a liquid amino acid to the crop straws, adjusting the initial pH to 3.0-4.0, and inoculating a liquid Trichoderma seed for solid fermentation. An acidity that allows Trichoderma to grow and multiply rapidly and inhibits the growth of other non-target fungi is established in the material by adjusting its pH value, an optimum nutritional formula for Trichoderma is screened out, and an inexpensive proprietary process for preparing a solid Trichoderma seed through fermentation is established. 1% of the solid Trichoderma seed is added to a matured compost, which allows the density of Trichoderma spores in the Trichoderma amended bioorganic fertilizer to reach above 5×107 spores/g, and the production increasing effect is considerable after the Trichoderma amended bioorganic fertilizer is applied.
