The present invention provides a kind of liquid crystal aligning film composition used for liquid crystal display (LCD), in which the liquid crystal aligning film composition used for LCD is a polyimide resin oligomer (A) having the structural formula (I) as shown in the following: wherein m is an interger of 1, 2, and 3, R is selected one of from aromatic and cyclicaliphatic, X is selected from the group containing amide, ester, and ether etc., Y is the group of containing cholesterol structure; this polyimide resin oligomer (A) and the second reagent (B) are mixed together, through an induced process (C), to produce a thin film for aligning liquid crystal molecule.

A carbon to liquids system is provided. The carbon to liquids system includes a source of syngas (202), a vessel configured to shift the syngas t o increase an H2 / CO ratio of the syngas, the vessel coupled in flow communication downstream of the source of syngas, a source of gas including hydrogen coupled in flow communication with the shifted syngas, the source of gas configured to be mixed with the shifted syngas to increase the H2 / CO ratio of the shifted syngas, a vess el including an inlet and an outlet, the inlet configured to receive the gas and shifted syngas mixture, the vessel including a catalyst configured to facilitate a Fischer-Tropsch synthesis reaction at a pressure of approximately 600 psia such that approximately 40% of the hydrogen / shifted syngas mixture is converted, and a recycle path communicatively coupled between the outlet and inlet configured to channel a n un- reacted hydrogen / shifted syngas mixture to the vessel inlet.

The invention relates to the technical field of tanning, and discloses a cationic cyanuric chloride derivative tanning agent and a preparation method thereof. The preparation method comprises the following steps of stirring and uniformly mixing 9.22-36.88 parts by mass of cyanuric chloride, 21.35-100.31 parts by mass of solvent and 7.12-33.44 parts by mass of deionized water under the ice-water bath condition to obtain a mixture A, dropwise adding 2.98-20.44 parts of tertiary ammonia compounds into the mixture A, and maintaining the temperature at 0-5 DEG C to obtain a mixed system, adjusting the pH value of the mixed system by using an acid-binding agent solution until the pH value is stabilized at 6.0-7.0, and reacting for 4-6 hours to obtain a mixture B, and filtering the mixture B to obtain a filter cake, washing the filter cake, carrying out vacuum drying under a vacuum condition for 4-6 hours to obtain a solid C, and grinding and crushing the solid C to obtain the white powdery cationic cyanuric chloride derivative tanning agent. In use, the characteristic that the cationic property of tanning leather fibers of a conventional chrome-free tanning agent is weakened can be improved, and meanwhile, the absorption and combination of crust leather on anion dyeing and finishing materials in the later dyeing and fat liquoring section can be improved.

The invention discloses a protein-based surfactant used for skin and hair cleaning and care and a preparation method thereof, comprising the following steps: (1) pretreating natural protein raw materials; (2) preparing the pretreated natural protein raw materials Alkaline protease and catalase are added to carry out enzymolysis and enzyme inactivation to obtain an enzyme-inactivating protein hydrolyzate; (3) purify and purify the enzyme-inactivating protein hydrolyzate, then remove the water and dry to obtain collagen (4) Using the microreactor as a reaction device, the collagen and diethanolamine are subjected to amidation reaction to generate collagen polypeptide amide; then the collagen polypeptide amide is esterified with lauric acid to prepare a protein-based surfactant. The invention uses natural protein that is easily discarded or low-level utilization as raw materials to produce a functional protein-based surfactant suitable for cleaning and caring for skin and hair and other special needs, thereby improving the utilization efficiency of natural protein resources.

The invention discloses a novel discharge module based on surface catalytic film enhanced ozone synthesis. The novel discharge module comprises a discharge unit package board, a venting element I sleeving an air inlet end of the discharge unit package board and a venting element II sleeving a gas outlet end of the discharge unit package board. The discharge unit package board comprises a sealing plate I and a sealing plate II. The lower surface of the sealing plate I is provided with a groove I. The upper surface of the sealing plate II is provided with a groove II corresponding to the grooveI. The groove I is opposite to the groove II. The sealing plate I and the sealing plate II are bonded through tops of groove walls of the groove I and the groove II. A discharge unit is arranged in aspace formed from the groove I and the groove II. A semiconductor film is electroplated on the lower surface of a dielectric plate 1 with a sheet metal electrode and / or the surface of a grid-shaped metal electrode, and in oxygen-containing gas as a gas source, the ozone synthesis is further promoted through a series of heterogeneous reactions in contact with plasma because of a large specific surface area.
