The invention provides a preparation method and applications of a nanocomposite material with an infrared absorption function. According to the technical scheme, the preparation method comprises the steps: (1) ultrasonically dispersing a porphyrin compound into a solvent, to obtain a solution A; (2) ultrasonically dispersing graphene oxide in the solvent, to obtain a solution B; (3) adding the solution B into the solution A, continuously stirring, performing oscillation and ultrasonic treatment until an upper-layer solution is clear, centrifuging, washing with a precipitating solvent, and performing vacuum drying; and (4) dispersing the precipitating distilled water subjected to vacuum drying in the step (3), then reducing through a reductant, cooling, centrifuging, washing, and performing vacuum drying, thus obtaining the nanocomposite material. The porphyrin compound and graphene oxide are combined and then reduced to obtain a porphyrin / reduced graphene oxide composite material, tests proved that the composite material can achieve multiband and wideband absorption effect on infrared rays, has excellent infrared absorption function and long-time stability; and the material is conveniently applied in a coating, and the infrared absorption waveband can be further increased through the synergistic effect of components.

The invention discloses an octapeptide and its application in preparing medicines for improving memory. The amino acid sequence of the polypeptide is: Trp-Cys-Pro-Phe-Ser-Arg-Ser-Phe (WCPFSRSF). The octapeptide of the invention can improve the memory impairment of mice induced by sleep deprivation, and can significantly inhibit the excitotoxicity and oxidative stress of nerve cells. The polypeptide of the present invention can be used alone as a drug for improving memory, or can be used in combination with other active ingredients that can improve memory, and can also be prepared into microcapsules to improve the digestive stability and bioavailability of the polypeptide in the gastrointestinal tract. And shelf life, so as to be better applied to the field of medicine.

The invention discloses a production method of a display panel, the display panel and a display device. The production method of the display panel comprises the following steps: providing a first substrate, wherein the first substrate is a hard substrate; forming a display module on the first substrate; adhering a first stretchable film to the surface, away from the first substrate, of the displaymodule; stripping the first substrate; and adhering a second stretchable film to the surface, away from the first stretchable film, of the display module. According to a technical scheme adopted by the invention, the problem that the stretchable substrate cannot be directly used as the substrate for flow processing due to relatively low temperature resistance, relatively low acid and alkali resistance and a large thermal expansion coefficient is avoided while the first stretchable film and the second stretchable film are used for achieving the stretchability of the display panel.

The invention discloses a preparation method of a NiAu nano-catalyst for producing hydrogen from borane ammonia, and belongs to the technical field of preparation of transition metal and noble metal binary materials in inorganic materials. In the present invention, nickel salt and chloroauric acid are firstly dissolved in oleylamine to make a mixed solution, stirred evenly by magnetic force and gradually heated up to obtain NiAu nanoparticles through reduction; then the cleaned and dried NiAu samples are heat-treated in a hydrogen atmosphere to obtain the final NiAu nanocatalysts. The NiAu particles prepared by the invention are uniform in size, good in dispersibility, have high catalytic efficiency for borane ammonia decomposition reaction, and can be converted into a highly stable Au@NiO core-shell structure in the reaction, and obtain no less than 200 cycles of catalytic activity (under the condition of more than 70% decomposition). The NiAu prepared by the invention is a simple, efficient and stable binary metal catalyst, which can be used in catalytic fields such as fuel cells, hydrogenation reactions, and methane reforming based on borane ammonia decomposition to produce hydrogen.

The invention relates to a miniature full-automatic honey pill machine. The miniature full-automatic honey pill machine comprises a frame, a slivering machine and a slitting and pill-rolling device. The slivering machine and the slitting and pill-rolling device are arranged on the frame. The slitting and pill-rolling device comprises a first motor, a transmission mechanism and two working gears. The working gears have semi-circular tooth grooves and tangent addendum circles. During operation, the first motor drives the two working gears to perform intermittent and reverse rotary motion by means of the transmission mechanism. In the gap of each rotary motion, the first motor drives one of working gears to axially move along an axial direction and restore to the original position. The slivering machine is used for machining mixed raw material to be bar-shaped and conveying the mixed raw material to the side where the two working gears are occluded.The miniature full-automatic honey pill machine has following beneficial effects: by adoption of three processes such as slivering, slitting and pill-rolling operation, honey pills are made; slitting and pill-rolling operation are performed by a same device; and the miniature full-automatic honey pill machine is simple in structure and convenient in transport and suitable for various occasions and occupies little space.

The invention provides modified bituminous concrete with a self-regulating temperature function. The modified bituminous concrete is prepared from the following raw materials in parts by weight: 100 parts of mineral aggregate, 3-7 parts of asphalt, 0.2-2.4 parts of sepiolite powder, 0.1-2.0 parts of palygorskite powder, and 0.01-0.06 part of coupling agent, wherein the coupling agent is a titanate coupling agent or an aluminate coupling agent; the aggregate grading type of the mineral aggregate is AM-13, GAC-13, AC-13, SMA-13 or OGFC-13.
