Preparation method of tilmicosin liposomes

The invention relates to a preparation method of tilmicosin liposomes. In the technical scheme, every 3g of tilmicosin raw powder is processed into tilmicosin liposomes by the following steps: (1) preparing a PBS buffer solution with the pH value of 6.5 to 7.5; (2) mixing egg yolk lecithin, cholesterol, octadecylamine, polysorbate-80 and ether in the proportion into a solution; (3) mixing the tilmicosin raw powder with the PBS buffer solution obtained in the step (1), and then pouring the mixture into the solution prepared in the step (2) and uniformly stirring; pulverizing the mixture by ultrasound into a suspension which does not delaminate within at least 5min; (4) transferring the suspension in the step (3) into a rotary evaporator to perform pressure-reduction rotary evaporation so that the suspension is condensed on the wall of the rotary evaporator to form lipid membranes; and (5) washing off the lipid membranes completely with the PBS solution obtained in the step (1), and thencontinuing the pressure-reduction evaporation until the ether is drained entirely to obtain tilmicosin liposome crude products. The method has the advantages of simple steps and strong operability. The prepared tilmicosin liposomes can be easily absorbed after being injected into livestock and poultry organisms; and the phenomenon of local swelling can not be caused.

In-situ detection device for chlorophyll concentration of water and detection method of in-situ detection device

The invention relates to an in-situ detection device for the chlorophyll concentration of water and a detection method of the in-situ detection device. The in-situ detection device and the detection method aim at solving the problems that in an existing device, the excitation light path can be not adjusted, the fluorescence intensity is low, and the fluorescence detection accuracy and sensitivity are low due to scattering generated when water contains lots of impurities. A water sample chamber water inlet device is arranged at the bottom of a quartz water sample chamber, a stainless steel shell is arranged outside the quartz water sample chamber, a detector, a light filter and a focusing lens are arranged over the quartz water sample chamber, a light source, a light source transverse adjustment support, a light source transverse adjustment mechanism and a light source direction adjustment mechanism are arranged on the side face of the quartz water sample chamber, and the detector, the light source, the light source transverse adjustment mechanism and a light source incidence angle adjustment mechanism are connected with a host through wires. The method includes the steps that water background fluorescence signals measured under the off-state of the excitation light source are collected, then water fluorescence signals under the on-state of the excitation light source are collected, and background fluorescence interference is automatically subtracted through operation.

Slab laser module with wave-front distortion self-correction ability

ActiveCN106602391ADoes not change the number of total reflectionsIncrease powerExcitation process/apparatusComputer moduleLight beam
The invention provides a slab laser module with wave-front distortion self-correction ability through optimizing thermal management and optical path design. The slab laser module comprises a laser reflection device and a slab medium used as a gain medium. The upper and lower surfaces at the two ends of the slab medium are evanescent-membrane-free areas, and the middle part between the upper and lower surfaces is an evanescent membrane area. Incident laser L1 enters the inside of the slab medium from the evanescent-membrane-free area at one end of the slab medium, is transmitted along the length direction of the slab medium, and goes out from the evanescent-membrane-free area at the other end of the slab medium. The laser reflection device reflects the output incident laser L1 into the slab medium for second transmission, and the incident laser L1 goes out from the incidence end of first transmission. The constraint condition for the point-of-incidence position of second transmission of the incident laser L1 is that the wave-front distortion waveform generated when the incident laser L1 passes through the slab medium for the first time and the wave-front distortion waveform generated when the incident laser L1 passes through the slab medium for the second time are opposite. Thus, output laser featuring no wave-front distortion, high power and high beam quality is obtained.
