Chapter 359: 1 dare to tell the truth, 1 dare to publish

There are six Nobel Prizes, including Chemistry, Physics, Physiology or Medicine, Literature, Peace, and Economics.
The next three awards are relatively more so. To put it bluntly, they are more water, and the gold content is not as high as that of natural sciences.
For example, the peace prize is easier for the elders of a beautiful country, and the literary 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, and the three natural sciences have a higher gold content.
If being able to publish an article in an SCI journal is regarded as an introduction to scientific research, then being able to write on the top journal of the CNS will almost begin to qualify for the Nobel Prize.
The general process is roughly: first select a question that is expected to impact the Nobel Prize, then propose a few theories and start to prove it, and finally prove to be successful, there is a chance of being nominated for the Nobel Prize.
And every year there are hundreds of nominees for the Nobel Prize. They still need to mix PK to determine the Nobel Prize winner of the year. This is the competition between the big bosses.
If he is not elected this year, he can be nominated again next year.
Therefore, most of the Nobel Prize winners in the natural sciences work at the age of 30 or 40, and then wait 20 or 30 years later, when they are 60 or 70 years old, before they can get the prize.
Of course, similar to the "good writing" in the circle, the scientific research circle is the same.
If the work is really good, it is not impossible to publish an article in the first year and be awarded a Nobel Prize in the second year, such as proposing quantum mechanics and relativity.
In fact, the two professors who discovered graphene won the Nobel Prize in only six years, which is very fast.
This is naturally also because the "discovery of graphene" is a very significant and profound achievement.
After all, the performance of graphene is really exaggerated.
First, graphene has ultra-high electron mobility, which plays a very important role in computer operating speed, which is 200 times that of current silicon-based CPU materials.
Second, graphene has the highest thermal conductivity among currently 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 breaking strength of graphene is extremely high, 200 times that of ordinary steel.
In addition, graphene has good light transmittance 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 will not stay in the scientific research stage, and the application will be realized long ago.
In today's scientific research circle, graphene is also a very popular field.
Earlier, Xu Qiu also saw an article published in the authoritative nanomaterials journal ACSNano, with the title "Can we put any stuff in graphene to increase its electrocatalysis?".
The ACSNano grade is slightly lower than the top publications such as AM and JACS, and should be almost at the level of AM sub-issues AEM and AFM.
The author used the same method to make two copies of graphene, one without any doping, and the other with bird droppings.
Then use Scanning Electron Microscope (SEM) to analyze its morphology, Raman spectroscopy to analyze its defects, X-ray electron spectroscopy (XPS) and X-ray diffraction (XRD) to analyze its element composition and chemical bonds, in addition to combustible element analysis, Feces-doped graphene is fully characterized.
In the end, the author came to the conclusion: the graphene treated with bird droppings is indeed better electrocatalytic than the undoped graphene.
Speaking of the future prospects of the experimental results, the author did not forget to express his desire for world peace:
"It is obviously cheaper to dope graphene with cheap bird droppings than with other chemical raw materials. In the future, we can also control the composition of chicken feed and further control the proportion of elements in chicken droppings. I believe that this kind of mixing will be used in fuel cells in the future. Graphene with feces has great potential. Bird feces is a material with high added value. I hope that countries will not launch any wars because of bird feces."
After reading the title and abstract, Xu Qiu knew that the author was mainly satirizing the large number of graphene papers in the material science field. By adding various substances to graphene to measure the performance improvement, he would be able to issue SCI...
Although this is indeed the current status of the scientific research circle, I did not expect that the author would dare to speak the truth, and the journal would really dare to accept this article.
Xu Qiu guessed that if the Chinese core is published, it is probably too likely to be sent for review...
After completing preliminary explorations in the simulation laboratory, Xu Qiu began sample preparation and testing.
The first goal of the water test is the ITIC system. Six groups of ITIC chlorobenzene solutions with different concentrations have been prepared in advance, with concentrations of 0.5, 1, 2, 3, 4, and 5 mg/ml, mainly to adjust the speed , To obtain thin films ranging in thickness from 5 nanometers to 100 nanometers.
There are three rotation speeds for each concentration of spin coating, respectively 2000, 3500, .m..
The first step is to tear off the thin layer of graphite on the surface of the HOPG with tape to obtain a fresh and smooth surface.
In the second step, a pure chlorobenzene solution is spin-coated on the HOPG substrate to clean the surface of the substrate.
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 spectroscopy (PL) instrument. Five sets of data are tested for each set of samples.
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 the fluorescence signal data without fluorescence quenching and the thickness of the sample are also required.
The latter two data only need to prepare samples of normal glass substrates under the same conditions.
Among them, the fluorescence signal directly measures the PL, and the thickness of the sample is reversed by the light absorption performance.
According to 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 films, the concentration of light-absorbing substances can be regarded 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 of 100 nm is 1, the thickness of the same film with an absorbance of 0.1 is naturally 10 nm.
Therefore, Xu Qiu again spin-coated 18 samples of normal glass substrates under the same conditions, and tested the light absorption spectrum and PL spectrum respectively.
The former tests one set of data for each sample, the latter also tests five sets of data, and finally obtains 108 sets of data.
All tests were completed, and it was past 11 o'clock in the evening. Except for Han Jiaying waiting in the inner laboratory, everyone else had already left.
Because the complexity of the data processing this time is more complicated than the exciton binding energy on Thursday and Friday, it is no longer a linear fit.
Therefore, it is estimated that it takes half a day or a day to process more than 200 data. Xu Qiu did not intend 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?"
"Yes, 200 data were measured this time, and it is estimated to be processed for one day tomorrow." Xu Qiu dropped the USB flash drive on the table and suggested, "Let's have a supper together?"
"Okay," Han Jiaying nodded, muttering: "I am also a little hungry, and I am going to gain weight again. What a sin, what should I eat?"
"Dark cuisine in the southern district?" Xu Qiu suggested. He ignored the school girl's thoughts. Every time she said that she would gain weight, she didn't change her weight in the end. This is probably enviable "No. Get fat" physique.
"Yes~" Han Jiaying said with a smile: "I want to eat fried rice cake with squid, and... grilled cold noodles."
"Look at you, you are drooling, pay attention to your image." Xu Qiu reminded with a smile.
The school girl subconsciously touched the corners of her mouth, "I am not drooling." After reacting, she gave Xu Qiu a light hammer: "Brother, you lie~"
Seeing the school girl's charming appearance, Xu Qiu said with a smile: "Haha, let's go."
After closing the laboratory, the two of them held hands and walked towards the south dormitory together.
The place where Xu Qiu rented a house was also near the South District, which happened to be on the way.
He still remembers when he first entered school, after seven o'clock in the evening, the whole street leading to the southern part of the headquarters was occupied by "dark cuisine" vendors. There were stalls on both sides of the school gate.
Later, in the first semester of the junior year, I don’t know if it was reported by someone or for other reasons. There was a wave of rectification by the city management. Basically, they came to arrest several times a month. As long as they were caught, they would be fined 500 yuan, and then a day or two The income is nothing.
So much so that the vendors are now shrunk in a small alley, afraid to set up a stall outside, and dared not run to the school gate until after 12 o'clock in the evening.
Urban management can’t still work at midnight, unless it’s the end of the year to make a performance...
Moreover, it is said that there are still special guards who have been staring at the nearby intersections, and immediately run off whenever there is a disturbance. The chances of hawkers being caught are much smaller.
The two walked to the small alley. It was during the summer vacation. The business was normal. Some hawkers would choose to rest or set up stalls in other non-school areas.
But ~EbookFREE.me~ is still infested by hawkers who live nearby.
In any case, summer vacation is not a winter vacation. Many students choose to stay in school or return to school early. Some are summer courses, and some are busy with social practice, or come to make up the exam after taking a course.
"Double-egg grilled cold noodles, add one portion of tenderloin, one portion of grilled sausage, one portion of Xiaoweilong, hot and sour flavor, boss, I have already paid for the money."
"okay."
"Alipay received 14 yuan."
"Boss, here's a fried rice cake with squid, a large portion, there are a few more in front."
"Just three, it's ready soon."
"Okay, I have paid the money, 25 right."
"Yes, do you want it spicy?"
"Slightly spicy is fine."
