The last time I dated Juchen, Ivanka heard him say that "marriage is a political or economic alliance", she was secretly sad, if you follow this logic, don't look at Ivanka's amorous style, in fact, she is the daughter of a small civil servant, her father also went to prison for a few years because of corruption, and after he came out, he did some small business, and he couldn't transfer a few dollars, so Ivanka came to Cotton Tree City to work, in terms of family background, Ivanka has nothing, with Juchen's current identity, I'm afraid ...... It's one thing to be in love, it's another thing to get married.

In order to test Juchen's mind, she took Juchen to see Swarovski's crystals and diamonds.

The fashion brand's crystals and diamonds have a very unique feature, they are both man-made, because they contain technological elements in them, and Ivanka thinks that men like Juchen will also be interested, and she herself will be interested. In fact, the price of a perfect man-made diamond is also expensive, almost reaching the price of 80% of natural diamonds.

The fire of crystals and diamonds is really attractive, Juchen is particularly interested in man-made diamonds, and bought some diamonds with the same cut as natural diamonds, 1 carat to 3 carats, and then went to Tiffany, which is famous for pure natural diamonds, to buy diamonds with the same cut, as well as expensive testing and ornamental equipment, and went back to compare the differences between them.

At the end of the day, the temptation failed completely, and Ivanka discovered that Juchen's interest was not at all in the "eternity" that represented the holy marriage, but in the craftsmanship of synthetic diamonds.

There was no way, and she was embarrassed to say it clearly.

Later, Juchen became more and more interested in man-made diamonds, and took time to visit some well-known man-made diamond factories.

A factory director personally received Professor Ju Chen, a science Internet celebrity.

Director: "The professor is also interested in diamonds, why?"

Taking advantage of Ivanka's absence, Juchen said: "My girlfriend took me to see diamonds, to test my mind, she actually knew that I would call man-made diamonds, and I was hooked when I saw it, so I looked around, how far has the synthetic diamond industry progressed now? compared to natural diamonds." ”

Director: "You're talking about gem-quality synthetic diamonds, but in fact, the cost is not low, and the price can't go up, so only 2% of jewelry diamonds are synthetic every year." The cost of synthesis is about $2,500 a carat, and the cost of natural products is only $50.

Ju Chen was surprised: "The cost of synthetic diamonds is so high!"

Factory director: "The cost of gem level is high, and the industry uses our China's world's largest output, and the technical difficulty is not too big." ”

Ju Chen: "What technology do you have now?"

Factory manager: "There are four kinds, the first is called HPHT, high temperature and high pressure, and the second is called CVD, chemical vapor deposition, which is planted in the factory and can be grown in two weeks, and this technology is currently the mainstream of manufacturing gem quality." The third method, called the detonation pressure method, uses the carbon contained in the explosives to synthesize nano-sized diamonds, which can only be used for industrial purposes. The fourth is the use of high-energy ultrasound, which I have only heard of, but have never seen. ”

Ju Chen: "I didn't expect that ultrasonic has such a huge amount of energy, and the cost of equipment must be not low." I've heard that there is a Popigai crater in Siberia that has more diamond reserves than the world combined, which is kind of interesting. ”

Factory director: "Yes, yes, yes, I have also paid attention to this, diamonds can only be formed under high temperature and high pressure, so there are nano-scale meteorites, and the crater of Popigai is against the sky, not only the nano-scale and micron-scale, but also the diameter of 2mm, the largest 10mm! It was discovered in Soviet times and has been kept secret. ”

Ju Chen: "In this way, the detonation pressure method is still very promising, simulating a meteorite impact, which can hit a 10mm large diamond. How big can a 10mm diamond be cut?"

Director: "It depends on what shape, if it is a princess square cut, the limit of 10mm can be 5 carats, and the most colorful brilliant cut, a little smaller, the most exaggerated olive type 5 carats need a diameter of 15.4mm." ”

Juchen nodded: "It seems that Popigai's diamonds are also valuable, I don't know why Russia's industrial diamond production is not the first in the world? Is the mining cost too high?"

Factory director: "In Siberia, where birds don't lay eggs, it is estimated that the cost cannot be reduced. ”

Ju Chen: "Are there any man-made diamonds that can't be detected by the instrument now?"

Factory director: "Yes! Almost undetectable, at least not with small instruments, expensive equipment is still OK, if expensive can't be detected, the industry has not heard of it, after all, diamonds may be generated in the mantle of 150 kilometers, no one knows the specific conditions, and the cost of the cottage does not know how high it is." What kind of craft are you interested in?"

Ju Chen: "Of course, it's the burst pressure method, and Popigai is a good example, it has potential." You say, can we use the principle of a ring accelerator to perform the burst pressure method? The purity, temperature, and pressure of this raw material are easy to control. ”

Factory manager: "Why is chemical vapor deposition popular? It is estimated that it needs to be maintained at a certain temperature and pressure for a certain period of time, and the diamonds produced by the burst pressure method are estimated to be nanoscale. ”

Ju Chen: "But the poppy cover can produce 10mm. Don't underestimate the power of the ring accelerator, it can even shatter atomic nuclei, no less energy than a meteorite impact. ”

Director: "But the meteorite is huge, and the accelerator can't simulate it, right?"

Ju Chen: "This can be compensated for by the purity of the raw materials, and I can estimate the critical value of purity by calculating the energy required for synthesis, just as Fermi estimated the critical value of the atomic bomb." ”

The factory director bowed: "Scientists are scientists, I really don't understand this." ”

Then, Juchen said goodbye to the factory director who had a good conversation, went back to calculate the critical value of the impact, and focused on solving it, and put aside the mundane affairs outside his body.

His calculations were very fast, and after checking the relevant information, he already had a plan, because when he was young, he learned the "dragon slaying technique" - estimating the critical value of the atomic bomb. I didn't expect that now that ten years have passed, I can still pick up the dragon slaying technique and use it.

No one in the industry has thought of using the principle of accelerator collision to expand the detonation method, Ju Chen reviewed the scheme roughly, applied for a patent, and submitted it to a well-known crystal journal, signed by Ju Chen, an associate professor at Columbia University.

Even if this matter was over, the director of the synthetic diamond factory was very concerned about the development of technology in the industry, and when the scientific journal published Ju Chen's paper in full, he immediately noticed it, and showed off everywhere that he had inspired Professor Ju Chen's idea.

At this time, Juchen had forgotten about this, and focused on the research and development of Filtered-Cig's 1 series of products, rapid development, large volume, like a Cuban cigar, glass material, you can see the burning cigarette from the outside, the filter is mainly concentrated near the end of the filter, more than a dozen adsorption materials, can filter the known 43 carcinogens, and almost perfectly reproduce the aroma of cigarettes (or the smell in the eyes of non-smokers).

Of course, there are many problems, such as: because of the closure, there is a problem with heat dissipation, it is a bit hot, and the cigarette ash affects the burning of tobacco after it is generated, and so on. However, tobacco factories have begun to deploy small-scale mass production to test the market.

Because cigarettes cannot be advertised, Juchen plans to issue cash coupons to retailers to promote, paste a QR code on the retailer, scan the code or the store's cash coupon, which can promote the sales of cigarettes in this store, and at the same time accurately promote their products to smokers on the page of the cash coupon.

Each user binds a mobile phone number, and the user's identity is determined jointly with the payment account, and the cash coupon can only be obtained once (temporarily). First of all, most of the people who come to scan the code are smokers, and secondly, they will not give cash coupons repeatedly, so that the promotion fee will be saved.

Of course, Juchen soon encountered a dilemma, it may be that BAT was ferocious, and the fine was reduced to one-tenth of the original in the second trial, $560 million became 56 million, and the money he received from crowdfunding exceeded this number, reaching 98 million.

When the results of the trial came out, the "investors" were shocked and scolded Professor Juchen for unscrupulous solicitation of money.

Now, their five-year corporate bond is fully counting on the success of Filtered-Cig, but judging by the current development, it is not optimistic.

BAT was very satisfied with the result, gave up continuing to appeal, and Juchen was not so greedy, so the lawsuit was settled.

Hehe, the corporate debt from crowdfunding is actually more than the fine, which is so TM interesting.
