Abstract: Provided is a buccal micro-effervescent tablet and preparation method thereof. The buccal micro-effervescent tablet includes a nutrient, a sugar alcohol, an acid source, an alkali source, magnesium stearate, an essence and a sweetening agent, wherein the sugar alcohol is lactose, maltitol, sorbitol, isomaltitol, mannitol, erythritol or any combination thereof and the sweetening agent is sucralose, aspartame, stevioside, fructose, granulated sugar, mogroside or any combination thereof. The micro-effervescent tablet is configured to cause a micro effervescence reaction under the action of saliva in mouth.

Abstract: The present invention discloses a method for preparing surface-active onion-like carbon nanospheres based on vapor deposition, comprising: directly preparing high-surface-activity onion-like carbon nanospheres formed by coating ferroferric oxide nano-particles on an onion-like graphitized shell by taking liquid small organic molecule alkane n-dodecane as a carbon source to perform chemical vapor deposition at high temperature of 650˜700° C. in an inert carrier gas environment with existence of a ferrocene catalyst. An onion-like carbon nanosphere product prepared according to the present invention has good surface activity and thermal stability, is wide in practicability, and can be widely applied to the fields of adsorbing materials, energy storage materials, catalytic materials, medical materials and the like.

Abstract: A printed circuit board structure and a wiring method therefor are disclosed. The printed circuit board structure comprises a first wiring channel formed inside the printed circuit board for transmitting a circuit signal; a pin, connected to the first wiring channel for connecting a chip to the printed circuit board; the pin comprising an unused pin and a used pin, the used pin comprising a peripheral pin and an internal pin; wherein the printed circuit board further comprises a second wiring channel, the second wiring channel leads out the internal pin by means of covering at least a portion of the unused pin. By means of using a printed circuit board structure and a wiring method to configure pins of the printed circuit board, the number of printed circuit board layers is reduced, and the current carrying capacity is enhanced.

Abstract: This application discloses a white-light hyperbranched conjugated polymer, a method for preparing the same and its use. The polymer uses a red phosphorescent Ir(III) complex as a core and polyfluorene derivative blue fluorescent materials as a framework which either contains or does not contain carbazole derivatives, and the white light hyperbranched polymers realize white-light emission by adjusting the content of the red phosphorescent Ir(III) complex connected using the complementation of blue and red color. The electroluminescent spectrum of the conjugated polymer in the present application covers the whole visible light emission area and is close to the pure white light emission, by which the conjugated polymer could be used as a material used in light-emitting layer to prepare the organic electroluminescent devices.
