I Have a Research Support System

There are six Nobel Prizes in total, including Chemistry Prize, Physics Prize, Physiology or Medicine Prize, Literature Prize, Peace Prize, and Economics Prize.

For the latter three awards, the relative comparisons, to put it bluntly, are relatively watery, and the gold content is not as high as that of the natural sciences.

For example, the Peace Prize is easier for the elders of the beautiful country, and the literature prize is biased towards Western ideology. Although the economics prize is officially awarded by the Nobel Foundation, it is not strictly a Nobel Prize. Because it was not established in Nobel's own will, but was added later.

The previous Nobel Prizes in chemistry, physics, physiology or medicine, the three natural sciences, have relatively high gold content.

If being able to publish articles in SCI journals is considered an introduction to scientific research, then being able to fill water in the top journals of CNS is almost eligible to hit the Nobel Prize.

The general process is roughly as follows: first select a problem that is expected to impact the Nobel Prize, then propose several theories and start to prove them, and finally prove successful, and you will have the opportunity to be nominated for the Nobel Prize.

And every year there are hundreds of nominees for the Nobel Prize, and they need to compete with each other to determine the Nobel Prize winner of the year. This is the competition among the big guys.

If you are not elected this year, you can be nominated again next year.

Therefore, most of the Nobel Prize winners in the natural sciences did their work when they were 30 or 40 years old, and then they won the prize when they were 60 or 70 years old 20 or 30 years later.

Of course, similar to the "literature can be broken" in the circle of novels, the same is true in the circle of scientific research.

If the work is really good, it is not impossible to publish an article in the first year and be awarded the Nobel Prize in the second year, such as the work of quantum mechanics and relativity.

In fact, the two professors who discovered graphene won the Nobel Prize in only six years, which is already very fast.

This is naturally also because the achievement of "discovery of graphene" is very important and far-reaching.

After all, the properties of graphene are indeed exaggerated.

First, graphene has ultra-high electron mobility, which plays a very important role in the running speed of computers, which is 200 times that of current silicon-based CPU materials.

Second, graphene has the highest thermal conductivity among known materials. Its thermal conductivity is 13 to 15 times that of silver, 80 to 90 times that of iron, and 8000 to 9000 times that of water.

Third, the fracture strength of graphene is extremely high, 200 times that of ordinary steel.

In addition, graphene also has good light transmission and flexibility. These extraordinary properties make graphene a well-deserved star material.

Of course, these performances are only theoretical, and they also face various problems in the actual application process, otherwise they would not still be in the scientific research stage, and the application would have been realized long ago.

In today's scientific research circle, graphene is also a very hot field.

Before that, Xu Qiu also saw an article published in ACS Nano, an authoritative journal of nanomaterials, titled "Can we put any shit in graphene to increase its electrocatalysis?".

The grade of ACS Nano is slightly lower than the top journals such as AM and JACS, and it should be almost the same level as AM sub-journals AEM and AFM.

The authors used the same method to make two copies of graphene, one without any doping and the other with bird droppings.

Then use scanning electron microscopy (SEM) to analyze its morphology, Raman spectroscopy to analyze its defects, X-ray electron spectroscopy (XPS) and X-ray diffraction (XRD) to analyze its elemental composition and chemical bonds, and also analyze combustible elements. Doped graphene for all-round characterization.

In the end, the author concluded that graphene treated with bird droppings does have better electrocatalytic properties than undoped graphene.

Talking about the future prospects of the experimental results, the author did not forget to express his desire for world peace:

"Using cheap bird droppings to dope graphene is obviously cheaper than using other chemical raw materials. In the future, we can also adjust the composition of chicken feed and further control the proportion of elements in chicken droppings. I believe that in the future, in fuel cells, this doping Graphene made from feces has great potential, and bird feces is a material with high added value. I hope that various countries will not start any wars because of bird feces.”

After reading the title and abstract, Xu Qiu knew that the author was mainly satirizing a large number of graphene papers in the material science circle. He could publish SCI by mixing various substances into graphene to test the performance improvement...

Although this is indeed the current status of the scientific research circle, I did not expect that the author would dare to tell the truth, and the journal would really dare to accept this article.

Xu Qiu guessed that if the Chinese core is released, there is a high probability that it will not be sent for trial...

After completing the preliminary exploration in the simulation laboratory, Xu Qiu began to prepare samples and test.

The first target to test the water is the ITIC system. Six groups of ITIC chlorobenzene solutions with different concentrations have been prepared in advance. , to obtain thin films ranging in thickness from 5 nm to 100 nm.

Each concentration was spin-coated at three rotational speeds, 2000, 3500, and 5000 r.p.m., respectively.

In the first step, tear off a thin layer of graphite on the surface of HOPG with adhesive tape to obtain a fresh, smooth surface.

In the second step, pure chlorobenzene solution was spin-coated on the HOPG substrate for cleaning the substrate surface.

In the third step, dry the substrate with a nitrogen gun, and spin-coat the ITIC solution.

The fourth step is to test the fluorescence signal of the sample with a fluorescence spectrometer (PL) instrument, and test five sets of data for each set of samples.

Constantly repeating the first step to the fourth step, Xu Qiu tested a total of 18 samples and obtained a total of 90 sets of data.

These 90 sets of data are the data after fluorescence quenching by HOPG, and it is necessary to obtain the fluorescence signal data without fluorescence quenching, as well as the thickness of the sample.

For the latter two data, it is only necessary to prepare samples of normal glass substrates under the same conditions.

Among them, the fluorescence signal is directly measured by PL, and the thickness of the sample is deduced through the light absorption performance.

According to the Lambert-Beer law, A=Kbc, where A is the absorbance, c is the concentration of the light-absorbing substance, b is the thickness of the absorbing layer, and K is a constant.

For solid thin films, the concentration of light-absorbing substances can be considered as a constant constant, that is to say, the absorbance is linearly related to the thickness of the sample.

Assuming that the absorbance of a film at 100 nanometers is 1, then the thickness of the same film with an absorbance of 0.1 is naturally 10 nanometers.

So, Xu Qiu spin-coated 18 samples of normal glass substrates again under the same conditions, and tested the light absorption spectrum and PL spectrum in turn.

The former tests one set of data for each sample, and the latter also tests five sets of data, finally obtaining 108 sets of data.

After all the tests were completed, it was past eleven o'clock in the evening. Except for Han Jiaying who was waiting in the inner laboratory, everyone else had already left.

Because the complexity of data processing this time is more complicated than that of exciton binding energy on Thursday and Friday, it is no longer linear fitting.

Therefore, it may take half a day or a day to process more than 200 data, so Xu Qiu didn't plan to process the data on the spot.

Seeing Xu Qiu coming out of the laboratory, Han Jiaying got up from her seat, gave him a big hug, and then said, "Brother, are you done?"

"That's right, I've measured 200 data this time, and it's estimated that I'll have to deal with it all day tomorrow." Xu Qiu casually threw the USB flash drive on the table, and suggested, "Let's have a late-night snack together?"

"Okay," Han Jiaying nodded, muttering, "I'm a little hungry too, and I'm going to gain weight again. It's so sinful. What should I eat?"

"Dark cuisine in the southern district?" Xu Qiu suggested, he ignored the young girl's thoughts, she said every time that she would gain weight, but in the end no matter how much she ate, her weight didn't change. This is probably an enviable "No Get fat" physique.

"Okay~" Han Jiaying said with a smile, "I want fried rice cakes with squid, and... grilled cold noodles."

"Look at you, you're drooling, pay attention to your image." Xu Qiu reminded with a smile.

The junior girl touched the corner of her mouth subconsciously, "I'm not drooling." After realizing it, she tapped Xu Qiu lightly: "Senior brother, you are lying~"

Looking at the junior girl's innocent appearance, Xu Qiu smiled and said, "Haha, let's go."

After closing the laboratory, the two held hands and walked towards the southern dormitory together.

The place where Xu Qiu rented a house was also near the South District, so it happened to be on the way.

He still remembered that when he first entered school, after seven o'clock in the evening, the entire street leading from the headquarters to the southern district was occupied by "dark cuisine" hawkers, and there were stalls on the left and right sides of the school gate.

Later, in the first semester of my junior year, I don’t know if it was reported or for some other reason. The city management rectified a wave here, basically came here several times a month, and as long as I was caught, I was fined 500 yuan, and then I was fined for a day or two. That's all for the income.

So much so that now the hawkers are shrunk in a small alley, afraid to set up stalls outside, and dare not run to the school gate until after twelve o'clock in the evening.

Urban management can't still work at twelve o'clock in the middle of the night, unless it's the year-end performance...

Moreover, now it is said that there are special sentinels who keep watching the nearby intersections and run away as soon as there is any sign of trouble. The chances of peddlers being caught have been reduced a lot.

The two walked into the small alley. It was the summer vacation and the business was so-so. Some vendors would choose to rest or set up stalls in other non-school areas.

However, there are still some hawkers who live nearby.

In any case, summer vacation is not winter vacation. Many students choose to stay in school or return to school early. Some of them are summer courses, and they are busy with social practice, or come to make up the exam after failing a course.

"Grilled cold noodles with double eggs, add a piece of tenderloin, a piece of grilled sausage, and a piece of Xiao Weilong, hot and sour. Boss, I have scanned the QR code and paid for it."

"okay."

"Alipay received 14 yuan."

"Boss, here is a fried rice cake with squid. It's a big one. How many more are there?"

"Just three copies, it will be ready soon."

"Okay, I've already paid the money, 25, right?"

"Yes, do you want it spicy?"

"Slightly spicy is fine."
