This invention discloses a method for determining the content of suberin monomers in the suberized tissue of yam tubers. Suberin is a macromolecular polyester, with monomers mainly covalently linked by oxygen-ester bonds. Its aliphatic compounds are linked to the polysaccharide components in the cell wall by glycosidic bonds and located on the inner side of the cell wall. Therefore, to determine the suberin monomer content, it is necessary to first destroy the plant cell structure, and then hydrolyze the oxygen-ester bonds between the suberin monomers to release the suberin monomer components. This invention first uses ultrasonic pretreatment to destroy plant cells, and then uses lipase hydrolysis combined with ultrasonic assistance and acid hydrolysis (sulfuric acid / methanol) to fully and efficiently hydrolyze the suberin into monomers. The reagents used are relatively safe and non-toxic, and the operation is relatively simple, solving the technical problem of difficult determination of suberin monomer content in the study of suberin metabolism after yam tuber injury healing.

The present invention discloses a core-shell thermal conductive powder and a preparation method for reducing the viscosity of polyurethane potting glue, and relates to the technical field of core-shell thermal conductive powder. The present application constructs an anchoring-bridging dual action mechanism through molecular-level interface engineering design. First, N-(N-butyl)-3-aminopropyltrimethoxysilane is used to graft thermal conductive powder.

The outer layer is coated with a long-chain aliphatic compound, and the nano-scale monodispersion of the thermal conductive powder is achieved through the steric effect, thereby reducing the viscosity of the system.
