Chen Guang thought that he had just arrived, and it was also a whim at this time, maybe he didn't want to come in a few days, but there was no need to tear his face with this boy.

Luo Jin was very hostile to Chen Guang, but Chen Guang didn't put him on the level of his opponent at all.

Although Chen Guang is very good to Zhuo Jingsi, in fact, he really has no superfluous thoughts in his bones, everyone has a lustful heart, and he can't deny that it is very refreshing to peek at Zhuo Jingsi's fullness, but it is only there, if he really wants to develop that kind of relationship with Zhuo Jingsi now, he has never thought about it.

In addition, what if this boy and Zhuo Jingsi have known each other for two years, the relationship between people is by no means a general summary of the length of time they have known.

For example, Zhou Long and Zhuo Jingsi have known each other since childhood, but Zhou Long is only afraid in her heart that he is no different from a fly that annoys people.

Zhuo Jingsi's mind was immersed in the real yàn number jù, and he didn't notice Luo Jin's hostility towards Chen Guang at all, and he didn't think much about it, so he called the other two girls over and introduced them to Chen Guang, even if they knew each other.

Unlike Luo Jin's hidden hostility, these two seniors are quite enthusiastic.

One of the two senior sisters is called Hua Ling, her hometown is from the northeast, and the other is called Zhong Yue, who is a little more beautiful than Hua Ling, and she is actually a fellow villager with Chen Guang, not the kind of far-fetched fellow, but a senior sister who is really from the same high school in the same county, graduated two years earlier than Chen Guang, and is now studying one.

Originally, Zhuo Jingsi planned to arrange for Luo Jin, the senior brother of the third year of research, to take Chen Guang to familiarize himself with the real room, but since Zhong Yue and Chen Guang were fellow countrymen, she simply took the initiative to take over the matter.

Chen Guang was also happy to arrange it like this, and he didn't want to deal with Luo Jin.

Luo Jin was a little unhappy in his heart, but he didn't say anything after all, but went to take care of himself.

"Chen Guang, you can watch me do it first and familiarize yourself with the actual process. Today, you came with your eyes first, look first, understand first, help me from time to time, and it will be your turn to do it in two days. ”

Zhong Yue said happily. When she met her old acquaintance in a foreign country, she was quite happy with her cheerful temperament.

Chen Guang nodded, "Then thank you for your advice." ”

Zhuo Jingsi's real topic is not big, but it is not small.

The catalytic degradation of pollutants in water bodies with photocatalysts has been done for a long time in the world, but their respective research directions are different.

Zhuo Jingsi aimed at phenolic organic compounds, combined with the current situation of the domestic pulp and paper industry, if the appropriate direction can be explored, it is bound to effectively reduce the emission of volatile phenolic pollutants. Further reduce the total amount of dioxin-type pollutants.

It's easier said than done.

There are many kinds of photocatalysts, and the research difficulty is not small, just to get started with Zhuo Jingsi took two whole years, and the analysis of the catalytic decomposition effect of single product catalysts is her master's thesis.

Subsequently, she found that the effect of the mixed type of catalyst was improved, and the cost of water treatment was greatly reduced, which could further explore the transformation from the real chamber stage to industrial applications.

There are dozens of photocatalyst materials. Some precious metals are extremely expensive, as she is a PhD student. There is simply no way to sustain such a huge research program.

Fortunately, her supervisor Shu Lirong recognized her scientific research results and intervened in time to further expand and extend the original master's thesis topic and declare it as a major project, so Zhuo Jingsi only needed to be responsible for the exploration of the catalytic effect of the mixing of three of the materials, although it was still too high-end as a doctoral dissertation. But I barely managed to do it.

Even so, it's not easy.

She had to constantly explore and adjust the mixing ratio of the three materials, and then she had to continue to explore the optimal dosing ratio, which was the optimal reaction concentration.

How many grams of photocatalyst powder is the most appropriate for a liter of phenol-containing wastewater?

Again, this is a huge proposition. The effect of catalytic degradation is not that the more photocatalyst is added, the better, in addition, if the cost is too high to be applied industrially, then the scientific research project will become a castle in the air, and there is no way to say it.

In addition, it is necessary to think about the most suitable wavelength of light for the photocatalytic reaction, and constantly fine-tune the wavelength of absorbed light to determine the catalytic effect.

In short, there may be a difference between the ultraviolet photocatalysis effect of 400nm and the ultraviolet photocatalysis of 395nm, and then it involves visible light and infrared light, which is a huge amount of work.

In addition, even the concentration of phenolic pollutants in sewage has to be deliberately and constantly changed, from 0.001mg/l to 100mg/l.

The wonderful thing about photochemistry is that when you don't find the right point, you may not feel a noticeable change in the parameters as you keep fine-tuning the parameters.

But once the tipping point is reached, it is very likely that the effect of the entire reaction will change instantaneously.

Taking the boiling point of some organic solvents as an example, the temperature has not reached the boiling point, even if the heater has been heating up, the solvent in the flask has never seen the slightest change, and it looks like it is frozen.

But once the critical point is reached, the solvent boils rapidly.

Studying the catalytic effect of photocatalysts is much more complicated than this, but the principle is the same.

Zhuo Jingsi's entire research project is composed of countless random parameter changes, the ratio of different photocatalyst materials is constantly adjusted, from 33:33:33 to 98:1:1, the quality of catalyst materials is constantly changing, from one milligram to several grams per liter of sewage, the pollution concentration of phenol-containing wastewater is from low concentration to medium concentration to high concentration, and the wavelength of absorbed light is changed from infrared to ultraviolet, and the wavelength changes from one nanometer to one nanometer.

The difficulty is not inferior to the more than 6,000 materials that Edison tried to invent the light bulb.

Modern scientific research, especially this kind of scientific research close to basic disciplines, has always been so boring that only on the premise of accumulating a large number of jù can we approach the essence of science step by step.

Even if he knew that he was facing tens of thousands of possibilities, he could only climb forward step by step like Prometheus stealing fire.

Professor Shu now has nearly ten doctoral students, including five doctoral students with four other teams in addition to Zhuo Jingsi, each tackling different catalytic effects of catalyst materials.

Zhuo Jingsi has been trapped in this project since she started her Ph.D. studies, and has experienced several major setbacks during this period.

For example, she chose nano iron dioxide, zinc dioxide and silicon dioxide as the entry point at the beginning, and chose platinum for coordination chelation, but she could endure for a year. After accumulating a large number of jù, she had the whim to replace the silica with strontium titanate, which was good, and the effect completely exploded all the proportions of the previous three materials, and she had to overturn them all again.

In fact, she didn't expect that she could really determine all the parameters and find the perfect point. It's not practical.

But it doesn't matter, even if her whole project is a complete failure, as long as she can sort out a large number of her own numbers and make a number of Jù curves and put them in international scientific journals, she can also get a lot of SCI impact factors.

Even if it is a failed research, if you help others eliminate the possibility of failure, it is still a scientific research achievement, and you can complete a doctoral dissertation.

If there is really someone in the world who can try all the photocatalysts and find the perfect ratio from dozens of materials. Then determine the reaction concentration, phenol-containing wastewater concentration, absorption light wavelength, reaction time and other parameters, and find the reaction conditions that can break the chain of phenolic organic compounds at the lowest cost and the highest efficiency, and it is not too much to give a Nobel Prize, but this is obviously impossible to achieve overnight.

In the process of research, there is a lot of luck, or there are more manpower and material resources, dozens of teams work together to tackle key problems, and after constantly fine-tuning the parameters, they can generally find a direction that can be applied industrially. That's pretty much a product.

Maybe it's still 108,000 miles away from true perfection, but this half-baked product can be made into a mixed liquid photocatalyst fluid and sold in the world. What awaits the project team will be amazing profits, and at the same time, it can also open up the situation that phenolic pollutants in China are difficult to control.

Chen Guang can now participate in the category a little later, there is also a set of biochemical treatment simulators in the corner of the real yàn room of Nuoda, in this simulator, the biodegradability of phenolic pollutants after the chain is broken can be roughly reflected. This is the smallest point in the industrial application category.

This is actually Zhuo Jingsi's worst plan, if it is really impossible to make a breakthrough in the general direction, then start small and implement it in the process of microbial biochemical reactions.

Phenolic contaminants have an inhibitory effect on microorganisms, the core factors in biochemical treatment, and can improve microbial activity after partial chain breakage. Further improve the effect of biochemical treatment.

The exploration of this matter can almost lead to a paper.

This is the case with basic scientific research, a big topic can be written from different angles, and a basket of papers can be written, as long as there is something to say, what is conclusively proved, and what is denied, it can be regarded as a scientific achievement.

As long as your paper can be published in a journal and recognized, it is considered that you have a certain degree of academic influence in the subject.

Neither Shu Lirong nor Zhuo Jingsi expected to really complete this great research, but in the process of research, Zhuo Jingsi alone has published more than ten papers in foreign journals, an average of one every two months.

In addition, the photocatalyst environmental protection application room of Wujing University, which is jointly composed of five groups, has become one of the only three national key practical rooms in Wujing University.

As for whether the real finished product can be taken out, no one has much hope, even if it is a large scientific research institution with an international reputation, investing a lot of manpower and material resources to tackle key problems, in April 2015, the University of Tokyo announced that they have really explored the available photocatalyst water purification technology, but there are still 108,000 miles away from widespread use.

The reason why the state supports this real room is also very simple, there is Shu Lirong, the leader of the discipline, and Professor Shu has gone further than others among the people who are doing this research in China, and there is hope to catch up with the international advanced level in scientific research.

Industrial applications may have to be in ten years, but if you don't do it now, you won't be able to catch up with foreign countries for the rest of your life.

It's something you know you can't do because you can't do it.

This is the normal state of modern scientific research, and it is precisely the thousands of people quietly doing this thankless thing that can continuously promote the progress of human science and technology.

The advancement of basic scientific research is particularly difficult, but once there are substantial results, it can really take a big step forward.

Taking Edison as an example, before the discovery that tungsten filament could be used to make incandescent lamps, most people in the world had to live in black lights and blind fires at night, but with the birth of incandescent lamps, thousands of households were illuminated in just a few years.

Some people have climbed to the sky in one step in the difficult exploration, but once they have succeeded, more people will live in obscurity.

With Zhong Yue's continuous help and introduction, Chen Guang spent five days on the first time to measure ammonia nitrogen, total phosphorus, total nitrogen and CODCR in wastewater before and after biochemical treatment, and at the same time further understood what a terrible thing Zhuo Jingsi was doing.

He couldn't help but be in awe. (To be continued.) )
