Abstract: Provided is a display panel including light-emitting unit package, which includes: a transparent substrate, a light shielding layer, a quantum dot layer and a light-emitting unit layer. The light shielding layer includes multiple first openings, multiple second openings, and multiple third openings. The quantum dot layer includes multiple first quantum dot units and multiple second quantum dot units. Each first quantum dot unit is correspondingly disposed in each first opening. Each second quantum dot unit is correspondingly disposed in each second opening. The light-emitting unit layer includes multiple first light-emitting units, multiple second light-emitting units, and multiple third light-emitting units with the same light-emitting color, each first light-emitting unit, each second light-emitting unit, and each third light-emitting unit are disposed corresponding to each first opening, each second opening, and each third opening, respectively.

Abstract: Disclosed is a method for identifying and eliminating ammonium salt deposition characteristics in a pipe of a hydrogenation air cooler. A multiphase flow medium enters an inlet pipe box of a hydrogenation air cooler; cross sections and temperature transmitters are arranged on a pipe bundle of the air cooler in the axial direction; a temperature signal value is monitored and transmitted to a single-chip microcomputer for analysis; an infrared thermal imager performs photographing, and transmits data to determine that an ammonium salt deposition risk is present under this working condition; a monitored temperature value is calculated, an ammonium salt deposition risk identification model is established, and ammonium salt deposits are peeled off from the inner wall of the pipe bundle of the air cooler by means of vibration of the pipe bundle caused by the intermittent frequent switching-on/switching-off of an electromagnet and a magnetic block, and ultrasonic signals.

Abstract: The present disclosure relates to a rice PAL1 gene, an encoding protein and use thereof. The rice PAL1 gene has the nucleotide sequence shown in SEQ ID NO. 1, and the rice PAL1 protein has the amino acid sequence shown in SEQ ID NO. 4. Mutation of the gene leads to reduction of rice plant height and panicle length, while decreasing the number of primary branches, secondary branches and grains per panicle. It is found that the PAL1 gene can restore a mutant panicle type to a normal phenotype. The present disclosure provides a PAL1 gene functioning as a regulator of the rice panicle length and an encoding protein thereof. A rice panicle type is an important trait influencing rice yield. Therefore, it will be desired to directionally design a plant type and improve the rice yield by regulating panicle traits of rice with the PAL1 gene.

Abstract: A vascularized full thickness tissue engineered skin assembled by hydrogel, nanofibrous scaffolds and skin cell layers and a preparation method thereof relate to a technical field of polymer materials and biomedical materials. The artificial tissue engineered skin includes an epidermis layer and a dermis layer. The epidermal layer is formed by alternately stacking upper nanofibrous scaffolds located above the dermis layer and a kind of seed cells. The dermis layer is formed by lower nanofibrous scaffolds, the hydrogel layer above the lower nanofibrous scaffolds, and three kinds of seed cells distributed on surfaces of the lower nanofibrous scaffolds as well as inside and on a surface of the hydrogel layer. The artificial tissue engineered skin is prepared by a combination of electrospinning technology, polymer complexation technology and fiber/cell layer-gel layer-fiber/cell layer self-assembly technology.
