This invention discloses a method for preparing N-doped β"-AlON solid electrolyte powder, which includes the following steps: (1) Slurry preparation: weigh anhydrous ethanol and dispersant, add the dispersant to anhydrous ethanol and stir evenly to obtain a mixed solution, then weigh aluminum source powder, lithium source powder, sodium source powder and nitrogen source powder to obtain a mixed powder, add the mixed powder to the mixed solution and stir thoroughly until the mixture is evenly mixed to obtain a mixed slurry; (2) Grinding to prepare precursor slurry: grind the mixed slurry thoroughly to obtain a precursor slurry; (3) Spray drying: spray dry the wet-ground precursor slurry to obtain spray-dried powder; (4) Calcination: calcine the spray-dried powder in a nitrogen atmosphere, and keep warm after calcination to obtain N-doped β"-AlON powder.

This invention relates to the field of garment care devices, specifically providing a trouser crease care device. It aims to solve the problem that existing clamp-type garment care cabinets often cannot accommodate trousers of different lengths, resulting in poor crease formation on trousers that are not properly compressed. To this end, the trouser crease care device of this invention includes a support frame, an upper hanging rod, and a lower hanging rod assembly. The upper hanging rod is connected to the upper end of the support frame and extends horizontally. The lower hanging rod assembly is movably connected to the lower end of the support frame and is configured to clamp the lower end of the trousers and pull it away from the upper hanging rod, thus tightening the trousers. Through this configuration, the trouser crease care device can accommodate trousers of different lengths and, through the upper and lower hanging rod assemblies, tightens folded trousers, thus forming a good crease.

The application belongs to the field of biomedical materials and biomedical engineering technology, and discloses a DFO@GMs-pDA / PN composite scaffold for promoting vascularization and osteogenesis, and a preparation method and application thereof. The DFO@GMs-pDA / PN composite scaffold for promoting vascularization and osteogenesis is constructed by using electrospinning, pDA modification and emulsification-extraction technology, and by wrapping DFO into GMs and loading the DFO into a pDA surface modified PN electrospinning film. The most superficial DFO@GMs begin to disintegrate and release DFO after implantation, and the maximum drug release rate is reached after 48 hours, so as to promote the ingrowth of new blood vessels, the recruitment of stem cells and the secretion and presentation of related factors in the early stage of bone regeneration, and to provide an important blood supply basis for bone regeneration.

The present application relates to a kind of new type of wall protection mud material for ultra-deep underground continuous wall and its preparation method, comprising the following steps: pour mixing water into the first container, while adding bentonite, the first container is stirred to be uniformly dispersed;Sodium carbonate, sodium carboxymethyl cellulose, xanthan gum and silicone acrylic emulsion are mixed and added to mixing water and poured into the second container, and stirred to be fully hydrated;Mix the solution in the first container and the second container, stir to be fully mixed, complete mud preparation.The beneficial effects of the present application are: it can avoid the hidden troubles such as excessive lateral earth pressure, large amount of mud loss, thin and dense mud skin cannot be formed when the excavation depth of underground continuous wall is large, configure a new type of modified bentonite wall protection mud with suitable physical stability and chemical stability, appropriate relative density, good mud skin forming property, which can adapt to the working condition of ultra-deep underground continuous wall, avoid the occurrence of hole collapse and shrinkage phenomenon, so as to ensure the quality of slotting and construction safety.

The application discloses a preparation method of a barrier antibacterial TPU composite film. Graphene oxide is prepared by using an improved hummers method, fluorinated graphene is prepared by using hydrofluoric acid as a fluorine source, the fluorinated graphene is used as a carbon source, and fluorinated graphene quantum dots are prepared under the action of an oxidant and an alkaline condition. Chitosan is dissolved in an acetic acid solution and reacts with the FGQDs under the action of dodecanol to form a barrier antibacterial agent CS / FGQDs. The TPU composite film produced by using the barrier antibacterial agent not only has a certain improvement in antibacterial performance, but also has improved barrier performance, and can generate great social and economic benefits.

The application belongs to the technical field of laser glass and optical fiber, and discloses a neodymium-doped near-infrared broadband emission germanate glass as well as a preparation method and application thereof.The neodymium-doped near-infrared broadband emission germanate glass comprises, in terms of molar percentage, 20-40% of R2O / RO, 5-15% of Nb2O5, 60-75% of GeO2, and the total percentage of the above components is 100%, and 0.5-1.5% of Nd2O3 is doped outside; R is another metal element.The glass has the advantages of easy preparation, wide fluorescence half-height width, good anti-crystallization stability and the like, and can be used in a high-peak-power and high-energy-pulse laser medium.
