Abstract: Provided are a method for manufacturing a molded composite inductor, and a molded composite inductor. The method includes: putting a plurality of conductors apart from each other into a mold, and extending two ends of each of the plurality of conductors out of the mold; filling the mold with magnetic powder such that the magnetic powder covers the plurality of conductors, and applying pressure to the magnetic powder such that the magnetic powder forms a magnetic body and is integrated with the plurality of conductors to form an inductor module.

Abstract: The present application relates to an internally embedded copper plate-type soft magnetic powder core inductor, a preparation method therefor, and a use thereof. The internally embedded copper plate-type soft magnetic powder core inductor comprises a copper plate, a surface of the copper plate is covered with a soft magnetic material, and an interfacing area of the soft magnetic material and the copper plate includes an insulating resin material.

Abstract: Disclosed in the present invention are a polyvinyl alcohol (PVA)-based degradable plastic, a preparation method therefor and application thereof, and a recycling method therefor. The preparation method comprises the following steps: a PVA solution is subjected to a chemical grafting reaction under an acidic condition under the action of a modifier; there are a phenyl group, an aldehyde group, and at least one group capable of forming a hydrogen bond with PVA in a structural formula of the modifier. The polyvinyl alcohol-based degradable plastic provided in the present invention has the advantages of being high in transparency, high in mechanical strength, not affected by environmental humidity, easy to degrade, good in thermal stability and good in biocompatibility, and has the advantages of recyclability, low costs, easy large-scale preparation and the like.

Abstract: A use of lactoferrin in the preparation of a food or drug, the food or drug being used for activating a VDR signaling pathway, which is used for the treatment of bone disease, bone disease comprising: osteoporosis, bone damage, loss of bone calcium, incomplete bone development and bone abnormalities. The present invention further comprises screening for drugs that are used to promote osteoblast proliferation and differentiation by using an active state of the VDR signaling pathway.
