Chapter 394 Required Technology

   "If they hand over all the technology related to magic power, they will relax the sanctions? Or will it intensify?"

  Wang Yi, who had already returned to the laboratory, couldn't help but feel a little funny after hearing the news relayed by Lin Shiqin.

  But this seems to be in line with their usual appearance.

  Anyway, bluff when you open your mouth, earn money if you bluff, and think of other ways if you don’t bluff, step by step.

  The old saying has always been used to describe it as "stealing by stealth", but they didn't do the superficial work of "snatching" and directly "snatched".

  The same is true for Umbrella this time.

   "Continue to work with them. How is the ammunition transformation going?"

  Wang Yi didn't say anything and asked Lin Shiqin to directly reject it. Anyway, he just dragged on. Let's listen to whatever you say.

   Time, on my side, continue to procrastinate.

   If a visitor from the abyss comes in the future, I will throw it on your head and let you save the world.

  That's what it says in the movie...

   "It has been completed. All the Ka-28s have been replaced with new equipment, as are the previous batch of drones."

   "That's good. The stability of the propellant and explosives here is almost the same. If the raw materials are enough, we can gradually replace them."

  Wang Yishou continued to conduct some verifications in front of the test bench.

  The current level of modification is almost enough to achieve the production of these two types of 'gunpowder' by Lin Shiqin's control of the magic machine tool alone.

  Cruise missiles have very high requirements for fuel because of their size and the amount of charges they carry.

  Although aviation fuel can also be used as propulsion, if you want to go further, you will often use polycyclic high-density hydrocarbon fuels, high-tension hydrocarbon fuels, and high-energy substances.

  There is still a distinction between the propulsion of cruise missiles and the propulsion of rockets and ballistic missiles.

  But since they have already made their own missiles here, of course Wang Yi also needs to optimize it.

  Because of the limitations of the size of the currently usable land in Penglai itself, Wang Yi also wants to complete the unification of the corresponding 'gunpowder' standards!

   That is, this propellant can also be used for other requirements in the future.

   This will naturally cause a little trouble.

  Finally, he chose a trinitro solid 'gunpowder' with a magic factor added!

   Depending on the mixing ratio, the oxidizing agent is different. This kind of 'gunpowder' that can be manufactured uniformly can be used as either a propellant or an explosive.

   And the power and performance are more than twice higher than the current competing products!

  In fact, the original version of Wang Yi has been produced a long time ago, but it is unstable and unsafe. After subsequent improvements, it has almost met the requirements for use.

   "Oh, in fact, the defense force is enough now, people are not asking about the propellant, the EUV lithography machine that ASML and the others have been holding back has already mass-produced a lot, and they have begun secret delivery.

   "It is estimated that after the first batch of debugging comes out, there will be an official announcement. My upgrade can also be put on the agenda. Anyway, it is already on my own site. The boss will come and help me upgrade."

  Lin Shiqin said in a flattering voice.

   "Penglai has already assembled the supporting production line for EUV. You can make it yourself. Don't ask me."

  Wang Yi was a little speechless.

  Lenses can be said to be the first place where he started his business. Even the principle of magic nuclear fusion was discovered when he was studying lenses.

  DUV lithography machine can be said to be just a product of 'testing the water'.

  Why do you always use dry photolithography?

  In fact, it is because the EUV lithography machine cannot use the immersion method, and even the EUV lithography machine cannot use the traditional dry method, but a 'vacuum' environment.

   Because EUV is already ionizing radiation, enough to ionize air, let alone liquid.

  In this case, DUV is of course outside the base camp, but Penglai was originally an EUV lithography system supporting lenses created by Wang Yi himself.

  The structure is quite similar to the previous DUV, a fully mature technology.

  Unlike ASML’s EUV lithography machine, because there is no lens that allows extreme ultraviolet rays to pass through, it needs to use reflection, and the energy loss is extremely serious. About 30% of each reflection is wasted, and finally only 2% of the utilization rate.

  As the volume increases, the high power of the light source also requires a cooling system, which is almost equivalent to opening a new track.

  So in fact, Wang Yi’s EUV lithography machine came out earlier, and the efficiency and yield rate are far higher!

   "But they also have EUV. The physical limit of silicon-based chips is almost reached. Boss, they need to upgrade~"

  Lin Shiqin's words also made Wang Yi a little speechless.

  She should be able to know that Wang Yi has certain restrictions on her improvement in quantum computing.

   After all, the computing power index addition of quantum computing, combined with Wang Yi's new formula algorithm, can easily lead to loss of control.

  But with the increase in computing power of classical computers, Wang Yi will definitely not give her any restrictions.

  EUV lithography machine, the resolution far exceeds that of DUV lithography machine.

  The 13.5nm wavelength is used, which is close to the extreme ultraviolet rays of X-rays.

  Theoretically, it has reached the limit of silicon-based chips!

   It is necessary to know that a single silicon atom is 0.12nm, and the electron tunneling effect must also be considered. Therefore, in the current normal view, 1nm is almost the limit of silicon-based chips.

  Of course, the tunneling effect had already appeared at the time of 20nm, and it was solved through structural adjustment. Maybe a solution was found after the 1nm process.

   But even so, the silicon atom size of 0.12nm is still here, and it is impossible to separate the atoms.

  In this case, what needs to be considered is either to increase the number of transistors by stacking the number of chips, to adopt new architectures and new methods, or to consider other materials.

  For example, carbon-based is one direction, but there are too many problems to be solved in carbon-based, and there are still many troubles.

   In addition to this, there is another material whose computing power can exceed silicon base by hundreds of times at the same density!

  And because the power consumption is extremely low, there is almost no heat dissipation problem, and it can be easily integrated and three-dimensionally superimposed, achieving theoretically an efficiency far exceeding the upper limit of the silicon base at the same scale.

  That is the superconducting material formed by Josephson junction.

  Yes, quantum computers also need to use superconductivity, but the application of superconductivity to computers is not limited to quantum computers. Traditional superconducting computers also have corresponding structures.

  Just because of cost performance issues and the current low-temperature superconducting materials, only a single Josephson junction has been made for testing, and no integration has been attempted.

We all know that superconductivity can be regarded as non-resistance and antimagnetic. Generally speaking, superconductivity itself cannot form a semiconductor. However, an oxide interlayer is added between two superconducting materials. Under the same conditions to achieve the same effect!

  This is the Josephson knot.

   It’s just that it’s too difficult to obtain superconducting materials.

  In most cases, superconducting materials need to be in a low-temperature environment of liquid helium to have superconducting properties, and the better one must be liquid nitrogen.

  But Lin Shiqin obviously meant to let Wang Yi roll out some room-temperature superconducting materials with his bare hands to help her.

"Boss, the data calculation of the mass projector has also been completed. To achieve the best effect, it is probably best to add superconducting materials. If you want to use traditional superconducting materials to add liquid nitrogen or even liquid helium refrigeration cycle device If not, the volume and engineering volume required will be greatly increased.”

  Lin Shiqin smiled like a little fox.

   "Okay, let me think about it and sort out my thoughts."

  Wang Yi sighed and rubbed his forehead.

  In fact, he has thought about superconducting materials several times. To be honest, he used magic power to **** a small piece of superconducting material at room temperature. It is a silver-copper alloy.

   It can be said that it was produced purely regardless of the cost, which seems a bit tasteless.

  Because most of the places where superconducting materials are used, the demand is actually quite a lot. Even the quantum computer of a certain song in "Plananus" uses much more superconducting materials than this one.

   Not to mention the current mainstream controllable nuclear fusion tokamak device.

   These are all combined with the cooling cycle device with the least liquid nitrogen, and some may still need to be cooled with liquid helium.

  But what Lin Shiqin said is correct, if you want to build a mass projector in the parameters, the best magnetic coil material to use is a superconductor.

  If you don’t come up with better superconducting materials, the additional cooling system itself will be a huge project.

   "Boss, recently someone used diamond to pressurize hydrogen sulfide and achieved superconductivity in an environment of -70 degrees. I found the relevant papers and experimental results..."

  When Lin Shiqin heard that Wang Yi was looking for ideas, she was very attentive and sent a lot of corresponding information, which made Wang Yi also feel a little interested.

  Hydrogen sulfide?

  Want to simulate the properties of metallic hydrogen? Diamond pressurization is indeed a very interesting idea.

  The other party uses physical correlation, and I can replace many places with magic power. Following the past, it may be easier to achieve the goal of room temperature superconductivity...

(Note: The paper on room temperature superconducting pressurization in 2020 was withdrawn, and it should be suspected of fraud, but another experimental team’s hydrogen sulfide superconductivity at -70 degrees in 2015, and hydrogenation at -23 degrees in 2019 There are examples of lanthanum superconductivity, but it needs to be pressurized to a pressure of 1 million to 2 million atmospheres with diamonds. This kind of experimental product may take a long time to be practical in terms of purely physical applications. It is not as good as liquid nitrogen. superconducting handy...)

   The third shift is over! Please subscribe~

   What cannot be solved by traditional physics can be solved by magic power, and technology is slowly getting dark...
