Chen Guang thought that he had just arrived, and this was just a whim. He might not want to come in a few days, so there was no need to fall out with this guy.
Luo Jin was very hostile towards Chen Guang, but Chen Guang didn't see him as an opponent at all.
Although Chen Guang treated Zhuo Jingsi very well, he didn't have any other thoughts. Everyone was lustful, and he couldn't deny that it felt good to peek at Zhuo Jingsi's body, but that was it. He never thought that he would develop that kind of relationship with Zhuo Jingsi.
Besides, so what if this guy had known Zhuo Jingsi for two years? The relationship between people couldn't be summarized by the length of time they had known each other.
For example, Zhou Long and Zhuo Jingsi had known each other since they were young, but in her heart, Zhou Long was probably no different from an annoying fly.
Zhuo Jingsi's mind was immersed in the experimental data, and she didn't notice Luo Jin's hostility towards Chen Guang at all. She didn't think much about it, and called the other two girls over to introduce them to Chen Guang.
Unlike Luo Jin's hidden hostility, these two senior sisters were quite friendly.
One of them was called Hua Ling, and her hometown was in the northeast. The other was called Zhong Yue, and she was slightly prettier than Hua Ling. She was actually from the same hometown as Chen Guang. It wasn't a far-fetched story, but a senior sister from the same high school in the same county. She graduated two years earlier than Chen Guang, and was now in her first year of postgraduate studies.
Originally, Zhuo Jingsi planned to arrange for Luo Jin, a senior in his third year of postgraduate studies, to show Chen Guang around the laboratory. Since Zhong Yue and Chen Guang were from the same hometown, she might as well take the initiative to do this.
Chen Guang was also happy to make such an arrangement. He didn't want to deal with Luo Jin.
Luo Jin was a little unhappy, but he didn't say anything in the end. He just went to do his own things.
"Chen Guang, watch me do it once and familiarize yourself with the process of the experiment. Today, you're here with your eyes. Watch first, understand first, and help me from time to time. It's your turn to do the experiment in two days."
Zhong Yue said happily. She was quite happy to meet an old friend in a foreign land, and she was quite cheerful.
Chen Guang nodded. "Thank you for your guidance, Senior Sister."
Zhuo Jingsi's experimental topic was neither big nor small.
Using photocatalysts to catalyze the degradation of pollutants in water bodies, similar research has been done for a long time in the world, but each person's research direction was different.
Zhuo Jingsi is targeting phenolic organic compounds. Combined with the current situation of the domestic pulp and paper industry, if a suitable direction can be explored, it is bound to effectively reduce the emission of volatile phenolic pollutants and further reduce the total amount of dioxin pollutants.
It was easier said than done.
There are many types of photocatalysts, and the research difficulty is not small. Zhuo Jingsi spent a whole two years just to get started. The analysis of the catalytic decomposition effect of a single photocatalyst is her master's graduation thesis.
Later, she found that the effect of the mixed type of catalyst has been improved, and the cost of water treatment has been greatly reduced. It can be further explored from the laboratory stage to industrial application.
There are as many as dozens of photocatalyst materials, and some of the precious metals are extremely expensive. With her status as a doctoral student, it is impossible to maintain such a huge research project.
Fortunately, her supervisor, Shu Lirong, recognized her research results and intervened in time to further expand this original master's thesis topic and declare it as a big project. Zhuo Jingsi only needs to be responsible for the exploration of the catalytic effect of the mixture of three materials. As a doctoral thesis, although it still seems too high-end, it is barely achievable.
Even so, it is not easy.
She has to constantly explore, constantly adjust the mixing ratio of the three materials, and then continue to explore the optimal ratio, which is the best concentration of the reaction.
How many grams of photocatalyst powder is the most suitable for one liter of phenol wastewater?
This was another huge problem. The effect of catalytic degradation was not necessarily better with more photocatalysts. In addition, if the cost was so high that it could not be applied in the industry, then the scientific research project would become a castle in the air, and there would be no way to start.
In addition, it is necessary to polish the most suitable light wavelength for the photocatalytic reaction and constantly fine-tune the absorbed light wavelength to determine the catalytic effect.
In short, there may be differences in the effect of ultraviolet light at 400 nm and ultraviolet light at 395 nm. When it comes to visible light and infrared light, the workload is outrageous.
In addition, the concentration of phenol pollutants in the sewage also has to be deliberately explored and constantly changed, from 0.001 mg/L to 100 mg/L.
This is the magic of photochemistry. When you can't find the most suitable point, you may not feel obvious changes even if you constantly fine-tune the parameters.
But once you think about the critical point, it is very likely that the effect of the entire reaction will change instantly.
Take the boiling point of some organic solvents for example. The temperature has not reached the boiling point. Even if the heater has been heating up, the solvent in the flask has never changed at all. It looks like it is frozen.
But once the critical point is reached, the solvent quickly boils up.
Studying the catalytic effect of photocatalysts is much more complicated than this principle, 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 the catalyst material is constantly changing, from one milligram to several grams per liter of sewage. The pollution concentration of phenol wastewater is from low concentration to medium concentration to high concentration. The absorbed light wavelength is changed from infrared to ultraviolet, and the wavelength changes are nanometers by nanometers.
The difficulty is no less than Edison trying more than six thousand materials to invent the light bulb.
Modern scientific research, especially this kind of scientific research close to the basic disciplines, has always been so boring. Only under the premise of constantly accumulating a large amount of data can one approach the essence of science step by step.
Even if you know that you are facing tens of thousands of possibilities, you can only climb forward step by step like Prometheus.
Professor Shu now leads nearly ten doctoral students. In addition to Zhuo Jingsi, a total of five doctoral students lead four other teams, each tackling the catalytic effect of different catalyst materials.
Zhuo Jingsi has been trapped in this project since she started her PhD. During this period, she has experienced several major setbacks.
For example, in the beginning, she had chosen nano-iron dioxide, zinc dioxide, and silicon dioxide as the entry point, and had chosen platinum as the coordination chelation material. However, after a year of suffering and accumulating a large amount of data, she suddenly had the idea to change the silicon dioxide to strontium titanate. Now, the effect was better than all the previous three materials, and she had to start all over again.
In fact, she does not really expect herself to be able to determine all the parameters and find the most perfect point. This is unrealistic.
But this does not matter. Even if her entire project is a complete failure, as long as she can sort out a large amount of her own data, make a data curve, and submit it to international scientific journals, she can also obtain a large SCI impact factor.
Even if it is a failed research, it is equivalent to eliminating the possibility of failure for others. It is still a scientific research result and can also be completed as a doctoral thesis.
If there is really someone in the world who can try all photocatalysts, find the most perfect ratio from dozens of materials, and then determine the reaction concentration, concentration of phenolic wastewater, absorbed 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, it would not be too much to give a Nobel Prize. But obviously, this is not something that can be achieved overnight.
In the process of research, luck is off the charts, or rather, more manpower and material resources. After dozens of teams work together and constantly fine-tune the parameters, they can generally find a direction that can be applied on an industrial scale. Then, they can almost produce a product.
Perhaps it is still far from perfect, but this half-baked product can also be taken out to make a mixed liquid photocatalyst fluid and sold on the market. What awaits the project team will be amazing profits, and at the same time, it can open up the difficult situation of phenolic pollutants in the country.
The scope that Chen Guang can participate in now is a little further. In the corner of the huge laboratory, there is a set of biochemical treatment simulator. In this simulator, it can generally reflect the biodegradability of phenolic pollutants after the chain is broken. This is the smallest point in the scope of industrial application.
This is actually Zhuo Jingsi's worst-case scenario. If she really can't make a breakthrough in the general direction, then she will start from a small point and specifically implement the process of microbial biochemical reactions.
Phenolic pollutants have an inhibitory effect on the activity of the core factors in biochemical treatment. After part of the chain is broken, the activity of the microorganisms can be increased, and the biochemical treatment effect can be further improved.
The exploration of this matter is almost enough to write a paper.
This was how basic scientific research was like. A big topic could be written from different perspectives. As long as it had something to say, it could prove something or disprove something, and it could be considered a scientific achievement.
As long as your paper can be published in a journal and recognized, it is considered that you have a certain academic influence in the discipline.
Neither Shu Lirong nor Zhuo Jingsi expected to really complete this great research. However, in the process of research, Zhuo Jingsi alone has published more than ten papers in foreign journals, an average of one every two months.
The doctoral leaders of the other four groups are not much worse than Zhuo Jingsi. In addition, the photocatalyst environmental protection application laboratory of Gokyo University, which is composed of five groups, passed the selection and became one of the only three national key laboratories of Gokyo University.
As for whether the real product can be produced, no one has much hope. Even the internationally renowned large scientific research institutions have invested a lot of manpower and material resources in the past few years. In April 2015, Tokyo University announced that they have really explored a usable photocatalyst water purification technology, but it is still a long way from widespread application.
The reason why the country supports this laboratory is also very simple. Professor Shu Lirong, the discipline leader, is currently working here. Professor Shu has gone further than others in this research, and there is hope for the level of scientific research to catch up with the international advanced level.
Industrial application may be ten years later, but if they don't do it now, they will never catch up with foreign countries.
This is something that they know is impossible, but they have to do it.
This is the norm of modern scientific research. It is precisely because there are thousands of people quietly doing this kind of thankless work that human science and technology can continue to advance.
The advancement of basic scientific research is particularly difficult, but once there is a substantial result, it can really take a big step forward.
Taking Edison as an example, before the discovery that tungsten filament can be used to make incandescent lamps, most people in the world had to live in darkness at night. However, with the birth of incandescent lamps, in just a few years, thousands of households were illuminated.
Some people rose to the sky in a single step in difficult exploration, but one success is built on the bones of thousands of people. More people spend their lives in obscurity.
Under Zhong Yue's constant help and introduction, Chen Guang spent five days to measure the ammonia nitrogen, total phosphorus, total nitrogen, and CODcr of the wastewater before and after the biochemical treatment. At the same time, he also gained a deeper understanding of how terrifying Zhuo Jingsi's actions were.
He couldn't help but be in awe.
