Even the oxygen source in the oxide can’t stop the forced combination of nitrogen 16.
In this way, the nanowires formed by alumina and boron oxide can be removed by nitrogen 16 to form elemental aluminum nanowires and boron nanowires.
Lu Xuedong is going to try it, but Huang Xiuyuan knows the synthetic technology. "Leave this part to me!"
"good"
Huang Xiuyuan, a returning scientist, led a dozen researchers to try to make boron oxide, aluminum oxide and copper oxide form nanowires.
In the materials laboratory
A heptagonal silica-sieve funnel-shaped side device is filled with boron oxide powder.
These boron oxide (boron trioxide) powders are screened and separated, which is also the most suitable state for synthesizing raw materials.
Because boron oxide is usually difficult to form crystals in a fixed state, it can also form crystals after high-intensity annealing.
After trying for more than a dozen times, Huang Xiuyuan improved the experimental heating mode and adopted the laser to focus on the heptagonal silicon oxide outlet.
This is a very fine work, which continuously burned hundreds of heptagonal silicon oxide films before debugging the qualified position.
The focus position of the laser is only about 23 nanometers away from the heptagonal silicon oxide nozzle, which is the limit.
It is not impossible to approach, but the laser near the nozzle will quickly burn the heptagonal silicon oxide film.
Even at this distance, a heptagonal silicon oxide film can work continuously for 1~12 hours at most, and it will be completely scrapped.
After laser sintering, a boron oxide nanowire was formed.
Huang Xiuyuan ordered "immediately test the strength and other characteristics of boron monoxide nanowires"
"white"
A group of researchers are also excited, and everyone is in a state of excitement.
Wu Can, a researcher in charge of testing, put boron oxide nanowires into a tensile strength tester and then carefully raised the tensile strength.
Several other researchers tested the cross-sectional diameter, resistivity, melting point, thermal conductivity, magnetism and so on.
Some physical properties of boron oxide nanowires formed after sieving and laser sintering have changed.
For example, although the tensile strength is better than that of non-carbon nanotubes, it is almost equal to that of ordinary steel wires.
Wu Can, a laboratory, reported to Huang Xiuyuan with the test report that "the strength of total boron oxide nanowires in Huang meets expectations".
Huang Xiuyuan immediately started an experiment. He turned his head and ordered "Prepare the oxygen stripping experiment"
"yes"
The experiment of oxygen source stripping is to make the whole device in boron oxide nanowire nitrogen release 16 powder be silicon nano-coating, so that the nitrogen 16 and oxygen source combiner must adopt silicon nano-coating.
The pave boron oxide nanowire is covered with a lay of nitrogen 16 powder, and that bottom of the device is heated, and when the temperature reaches the specify position, strong ultraviolet radiation is started.
Temperature and ultraviolet nitrogen 16 quickly decompose nitrogen 16 near boron oxide nanowires and combine with oxygen in boron oxide to form nitric oxide.
When all nitrogen 16 is decomposed, boron nanowires remain in the reactor.
Several researchers took the boron nanowire out of the device with care and sent it to the laboratory for testing immediately.
Or WuCan and others are responsible for testing.
The boron nanowires left after being stripped of oxygen are obviously fragile, and some tensile strengths are similar to those of ordinary cotton threads.
Huang Xiuyuan is very clear about this result. Although this tensile strength is fragile, it is not without solutions.
If the strength of single-wire boron nanowires is insufficient, the boron nanowires can be turned into boron nanowires by multi-wire weaving.
Moreover, the tensile strength of boron nanowires is not too high, and it only needs to reach the strength of ordinary cotton rope
After completing the research and development of boron nanowires, aluminum nanowires and copper nanowires were also developed by Huang Xiuyuan.
On the contrary, the phosphorus nanowires and arsenic nanowires on Lu Xuedong’s side fell into dystocia.
Laboratory rest area
Lu Xuedong took a sip of black coffee and smiled bitterly. "You are too fast there, aren’t you? Why don’t you try phosphorus nanowires and arsenic nanowires?"
Smell speech Huang Xiuyuan shook his head. "It’s too expensive to produce silicon oxide films by laser sintering according to the established route."
"That’s more than ten hours. A piece of film is really troublesome." Liu Xuedong also temporarily put the idea of changing the route
If phosphorus nanowires or arsenic nanowires with appropriate strength can be directly generated through pentagonal silicon oxide films, they need all the raw materials.
"I believe you" Huang Xiuyuan patted him on the shoulder.
