Abstract: The present invention discloses a terpinenol compound as well as its preparation method and application. The structure of such terpinenol compound is as shown in Formula (I) or (II). In Formula (I), R is independently selected from C12-C16 alkyl, —NR1R2, —SR3 or —OR4; R1, R2, R3 and R4 are independently selected from C1-C6 alkyl or —NO2; the C1-C6 alkyl can be substituted by OH; Alternatively, the R1 and R2 form a five-member ring or six-member ring in together with N used to link up them; the five-member or six-member ring may contain one O or C?O. As indicated by results of activity test, such terpinenol compound has satisfactory effect in prevention of asthma, inflammation and pulmonary artery hypertension, which also has high pharmaceutical significance.

Abstract: A multi-channel flow direction controller for a free-flow electrophoresis apparatus, including a base and a propulsion member. The base is provided with a plurality of convex pieces. The propulsion member is provided with a plurality of narrow pieces. The convex pieces and the narrow pieces have the same length and number. One end of the base is provided with a groove, and one end of the propulsion member is disposed in the groove.

Abstract: An exhaust and separation device for a free-flow electrophoresis apparatus, including a buffer reservoir, a buffer pump, a manual inflator, a gas-liquid buffering and separating member, a self-balancing recovery device, and a separation chamber. The separation chamber includes a shell including an upper cover plate, an ion-exchange membrane, and an insulating and thermal conductive base plate. The inlet of the buffer pump is connected to the buffer reservoir via a first connection pipe. The upper surface of the gas-liquid buffering and separating member is provided with an air inlet and a liquid inlet. The lower surface of the gas-liquid buffering and separating member is provided with a plurality of liquid outlets. The separation chamber is provided with buffer inlets and buffer outlets on two ends, respectively. The outlet of the buffer pump is connected to the liquid inlet of the gas-liquid buffering and separating member.

Abstract: Disclosed is a lanthanum doping catalyst for preparing carbon nanotubes having uniform diameter and producing method thereof. The catalyst comprises magnesium oxide as a support, two or three metal oxides selected from the group consisting of ferric oxide, cobalt oxide, and nickel oxide as a complex metal oxide composite, lanthanum oxide as a lanthanum doping composite, and molybdenum oxide as an enhanced catalytic composite. The catalyst is produced by dissolving magnesium salt into distilled water, and into the solution is added metal salt for forming complex metal oxide composite, lanthanum salt for forming lanthanum doping composite and salt for forming enhanced catalytic composite in a molar ratio of 0.5-3.0:0.1-1.0:0.01-1.0:0.5-3.0. The solution is dissolved completely and dried at 120-200° C. for 3-5 hours. Then, the product is calcinated at 550-850° C. for 10-30 minutes and grind to be a fine powder.
