The rise of nanometers

Researcher Yan said with a smile: "This technology is currently undergoing clinical testing, and I believe it will be on the market in the near future."

"Are those nanoparticles and catalysts harmful to the human body?" Liu Xing asked.

Researcher Yan shook his head: "The nanoparticle is a calcium carbon molecule. After contact with the catalyst, it will turn into a component similar to bone. The catalyst and by-products are carbon dioxide and elemental silver, which are not harmful."

"This technology is good!"

"According to the introduction, it only takes ten minutes to complete the tooth grafting, which is much faster than dental implants."

"I had a tooth implant last year and it was such a hassle."

Researcher Yan said with a smile: "Everyone, are you interested in giving it a try? The whole process only takes about an hour."

Tian Shengwen, who had pulled out a molar himself, his eyes lit up: "Is it okay? I pulled out a molar a few years ago. Can I get a dental implant?"

"Okay, let me take you to check first."

Everyone followed curiously and came to the dental implant research area of ​​the laboratory. Researcher Yan and several other researchers discussed it in a low voice.

A dental researcher examined Tian Shengwen's teeth and nodded: "It can be done. Your molars have completely fallen out and the alveolar bone has also shrunk. You can have dental implants."

Then Researcher Yan took a letter of commitment, a test cooperation letter, and a disclaimer, and asked Tian Shengwen to sign.

Because Tian Shengwen had been extracting teeth for so long, the alveolar was covered with flesh and needed to be cut again. The dentist gave him anesthesia and then cut through the flesh tissue to expose the alveolar bone underneath.

The excess flesh tissue was cut off, the depth of the alveolar bone was cleaned and measured, and an artificial tooth was obtained to try to match the height and upper and lower bite.

The dentist then began to inject calcium carbonate nanoparticles into the alveolar bone, while Researcher Yan injected calcium carbonate nanoparticles into the bottom of the artificial tooth.

After half an hour of busy work, the artificial teeth were fastened to the empty space of the alveolar bone using temporary braces, and then the catalyst was started to be injected.

Researcher Yan, who was cooperating on the side, held a negative pressure suction tube and sucked the elemental silver and saliva produced at the binding site.

As for the other by-product, carbon dioxide, the amount is not as much as the carbon dioxide produced by a 200 ml bottle of Coke.

After about 12 minutes, the alveolar bone and artificial tooth were completely integrated, and the dentist removed the catalyst nozzle.

"Tian Logistics, rinse your mouth."

Tian Shengwen took the mouthwash and cleaned his slightly numb mouth.

In fact, the most painful part of the whole process is the incision of the flesh tissue. There is no discomfort during the tooth grafting process.

The dentist took off his gloves and ordered: "In the next few days, you only need to pay attention to the inflammation of the incision. If there is severe inflammation, you must take anti-inflammatory drugs."

Tian Shengwen is from the medical system, so he naturally knows some common sense. He nodded: "I will pay attention to my diet."

The dentist took another small bottle: "Here are three anti-inflammatory pills. If the inflammation is severe, you can take it."

"Thank you." Tian Shengwen took the small bottle.

Then Liu Xing and others asked about how they felt about dental implants. About half an hour later, the dentist came over and removed the temporary braces.

Tian Shengwen was asked to try biting again to see if there was any bulge.

Although the depth of the alveolar bone and the height of the two adjacent teeth were measured before the tooth was implanted, and an upper and lower bite was attempted, there was still the possibility of a small amount of bulge.

If the bulge is too obvious, the dentist will need to perform a second teeth grinding to ensure that the artificial teeth fit perfectly.

However, Tian Shengwen tried to bite hard several times, but there was no obvious discomfort. At most, he was a little uncomfortable.

Liu Xing turned around and asked: "Researcher Yan, after the new dental implant technology is released, what is the estimated cost of a single tooth?"

"The cost is quite cheap. If the research and development expenses are shared according to the usual practice, the cost of a single tooth should be around 200 yuan, and the selling price should be around 600 to 700 yuan. Including the dentist's fee, a single tooth should be around 1,500 yuan."

After hearing this price, everyone felt that the new dental implant technology had great potential.

Compared with old-fashioned dental implants, which often cost tens of thousands, the new dental implant technology is not only easy to operate, but also highly cost-effective. It also eliminates the need for titanium alloy screws, reducing the patient's pain.

This is the impact that technological development has on human life. Future technology will increasingly consider the user experience while ensuring effects.

Although the old dental implant technology allows patients to have a second set of teeth, the dental implant process makes the patient very uncomfortable and expensive.

A tooth costs tens of thousands, and a set of teeth can be replaced with dental implants. The price is enough to buy a mid-range car.

The emergence of new dental implant technology is undoubtedly a very friendly new technology for ordinary people in China. One tooth costs about 1,500 yuan, which many families can afford.

Soon, five days are up.

Liu Xing and Tian Shengwen got the mutated T cells that had just been cultured, and hurriedly took the tram back to Pengcheng.

At this time, there are only three days left before New Year's Eve 2013.

In the past few days at the Luhe headquarters, Liu Xing and Tian Shengwen were on vacation. The meals at the headquarters made them a little happy.

However, there is no such thing as a banquet that lasts forever, and the two of them will eventually return to work.

The light rail trams are still on the rails, maintaining the transportation of people and materials from various places. The scenery along the way just has a touch of the new year.

Liu Xing took out his laptop and continued to immerse himself in learning.

Buried in a vast sea of ​​information, more than an hour passed before he knew it. He wiped his dry eyes.

Suddenly, he saw a piece of news rising rapidly in popularity on the Time Blog's news hot list. Curious, Liu Xing clicked on the news, and it turned out to be news about semiconductors.

[TSMC announced that it has conquered the key technologies of the 16nm process and is expected to launch a mass-production 16nm process around June this year...]

Although he paid little attention to the semiconductor industry, as a member of the Suiren Department, Liu Xing still read the press release carefully.

This press release was forwarded by the Global Times to TSMC’s official website, so its credibility should be pretty good.

After all, there is a news media rating system on Time Blog. Generally, only news media with a comprehensive score of 9 to 10 are credible and authoritative.

Many domestic news media have comprehensive scores that are even lower than the passing line of 5, which is the same as the BBC and CCN.

For this rating, Time Blog has fought many lawsuits with more than a dozen news media. However, since there is no explicit regulation, Time Blog has always insisted on its own rating.

This makes many news media very helpless. Time Blog likes to crack down on counterfeiting. Whether it is products or news, they are all within the scope of cracking down on counterfeiting.

The news media that were beaten to death have no way to deal with Time Blog, because Time Blog speaks with truth and facts. If it dares to spread rumors, cause trouble and publish fake news, it will have to bear the corresponding consequences.

The overall score of Global Times is around 9.2, which is relatively authoritative and has relatively high credibility.

Liu Xing looked at TSMC's 16nm process and searched for the current development of chip technology among global semiconductor companies.

Found nothing but the dragon totem.

A week ago, Intel announced that it would launch the 18nm process at the end of March this year.

Samsung also announced that it will launch its own 16nm process around June this year.

The photolithography camp kept issuing announcements, as if they were planning a full-scale counterattack on the textile method, but Dragon Totem's silence and calmness made those opponents feel vaguely uneasy.
