Embodiment 1

[0031] figure 1 The included angle between the generatrix of the shown open carbon nanocone 2 and the bottom surface is 70.55°, and the height is The upper opening radius is The object to be accelerated is fullerene C180. The compression process of this open carbon nanocone and the rebound fullerene C180 process are carried out based on the molecular dynamics simulation of Lammps software (Lammps is a commonly used open source simulation software, see https: / / lammps.sandia.gov / ), and finally obtain the relationship between the kinetic energy of fullerene C180 and the strain of the open carbon nanocone, the result is as figure 2 shown.

[0032] When the speed of fullerene C180 is accelerated to 500m / s, its kinetic energy is 3.41eV, and the speed can be realized in the linear elastic stage of the open carbon nanocone. The specific implementation includes three steps:

[0033] Step 1: First, set the angle between the bus bar and the bottom surface to be 70.55°...

Embodiment 2

[0038] When it is necessary to accelerate the speed of fullerene C180 to 1400m / s, by figure 2 It can be seen that this accelerated process can be realized in the buckling stage of the open carbon nano cone (consistent with embodiment 1), and the specific implementation includes three steps:

[0039] Step 1: The kinetic energy needed to accelerate the speed of fullerene C180 to 1400m / s is about 21.60eV, then according to figure 2 It can be determined that when the strain of the open carbon nanocone is 0.16, the corresponding kinetic energy converted is about 21.60eV, so an external pressure is applied to the top of the open carbon nanocone, and the open carbon nanocone 2 is compressed to a strain of 0.16;

[0040] Step 2: Place the fullerene C180 above the compressed open carbon nanocone 2, and keep the distance between the bottom of the fullerene C180 and the upper bottom surface of the open carbon nanocone at

[0041] Step 3: release the compressed open carbon nanoco...

Embodiment 3

[0043] When the speed of fullerene C180 needs to be accelerated to 1800m / s, by figure 2 It can be seen that the compression of the open carbon nano cone (consistent with embodiment 1) can be realized near the extreme, and the specific implementation includes three steps:

[0044] Step 1: The kinetic energy needed to accelerate the speed of fullerene C180 to 1800m / s is about 36.64eV, then according to figure 2 It can be determined that the required strain of the open carbon nanocone is 0.26, so an external pressure is applied to the top of the open carbon nanocone to compress the open carbon nanocone 2 to a strain of 0.26;

[0045] Step 2: Place the fullerene C180 above the compressed open carbon nanocone 2, and keep the distance between the bottom of the fullerene C180 and the upper bottom surface of the open carbon nanocone at

[0046] Step 3: release the compressed open carbon nanocone 2, and the open carbon nanocone 2 instantly recovers its deformation, and part of...

Abstract

The invention discloses a nanometer material ejection acceleration method, and belongs to the field of nanofabrication technologies. The nanometer material ejection acceleration method comprises the steps of firstly, putting pressure on an upper bottom surface of an open carbon nanocone to make the open carbon nanocone obtain certain strain, and after a to-be-accelerated object is placed over the open carbon nanocone, releasing pressure over the open carbon nanocone to make strain energy stored in the open carbon nanocone act on the to-be-accelerated object, so as to accelerate the nanoscale object. According to the method, through a method of controlling the compression amount of the carbon nanocone, the speed of the to-be-accelerated object can be controlled, the use requirements in different environments are achieved, and change of the speed from lower than 100 m/s to 1800 m/s of nanoparticles can be achieved.

Description

technical field [0001] The invention relates to a method for ejection acceleration of nanometer materials, which belongs to nanometer processing technology. Background technique [0002] With the development of nanotechnology and the continuous development of various physical and chemical methods, researchers generally obtain the prototype of nanomaterials by means of reagent reaction, material growth, firing, vapor deposition, etc. , and then processed with ultra-precision processing methods to get. Due to the requirements of nanoscale processing technology, there is a demand for nanoscale driving devices. At the nanoscale, the requirements for the driving device are different from those in the macroscopic state. The biggest difference is the way to drive the material to achieve high-speed motion. Generally speaking, the macroscopic driving device, such as the speed of a gun driving a bullet, has Reaching 300m / s to 1000m / s requires the use of gunpowder explosions, etc. At...
