The invention discloses a detection method for distinguishing the influence of concentration on a secondary structure of a protein molecule. The detection method is characterized by comprising the following steps: (1) dropwise adding a to-be-detected protein molecule solution onto the surface of a subface by utilizing a Langmuir-blodgett membrane forming technology, and observing whether a Langmuir single molecular membrane can be formed or not; (2) collecting the variation curve of the surface pressure pi from the moment of dropwise addition if the Langmuir single molecular membrane is formed, i.e. a pi-t kinetics curve, wherein the secondary structure of the protein is maintained good if the pi in the pi-t kinetics curve is a curve which rises and finally stays at a stable numerical value; the protein is severely solvated if pi in the pi-t kinetics curve is in a descending trend, and the secondary structure is damaged. The detection method can be used for monitoring the variation of the ...

The invention discloses a method for preparing a molybdenum-disulfide (MoS2) nanotube. The method is characterized by comprising the following steps of preparing a C-MoS2 coaxial nanotube wrapped by homogeneous MoS2 by taking a fibrous carbon (C) nanomaterial as a template, and calcining the C-MoS2 coaxial nanotube at a high temperature in a flowing CO2 atmosphere to remove C to obtain the MoS2 nanotube. The thickness of the wall of the MoS2 nanotube prepared by adopting the method can be controlled by changing the thickness of the MoS2 wrapping layer in the C-MoS2 coaxial nanotube. Because the raised surface or sharply bent part of the fibrous C nanomaterial can not be totally wrapped by MoS2, the prepared MoS2 nanotube has structure defects correspondingly, but the number of active spots on the edge of the MoS2 nanotube can be increased due to the structure defects so that the MoS2 nanotube has excellent optical and catalytic properties.

The invention discloses a composite nanotube composed of a molybdenum disulfide-carbon-carbon nanotube and a preparation method thereof. The method comprises the following steps: firstly, orderly dissolving ammonium tetrathiomolybdate and a carbon high-molecular polymer with surface activity into water; then adding a multiwalled carbon nanotube; centrifuging, drying and burning after carrying out ultrasonic dispersing, so as to prepare MoS2-C/CNTs. By using the surface activity of a carbon high-molecular polymer, the molybdenum disulfide is more evenly dispersed on the surface of the carbon nanotube; on the other hand, the conductivity of a compound is improved through the compound of amorphous carbon and molybdenum disulfide left on the surface of the carbon nanotube when a mixture is burnt at high temperature.
