Massachusetts Institute of Technology, School of Materials Science and Engineering Laboratory.

Professor Jeffrey Grossman stared at the computer screen and turned the pen in his hand, but his mind was thinking about a difficult problem encountered in the experiment.

As a big star in the field of materials chemistry, he is now in a hot period.

The year before last, after he made a harvest from polyamide composites, he did not strike while the iron was hot and continued, but turned to solar thermal energy to store new materials, and then it took less than a year to publish a paper on new materials in the journal "Nano Express".

This new material can store and release heat energy on demand, and the heat storage equipment made of this material not only has a high energy storage density, but also has the characteristics of low cost, convenient transportation and long energy storage time, which can be said to create a new way to capture and store solar energy.

Although this technology is still a long way from commercialization and industrialization, the potential in it, needless to say, is promising.

You know, since the 70s of the 20th century, scientists have been looking for a material that can store solar energy in chemical form instead of converting it into electricity, but the relevant research was not progressed until last year: 2009!

Because as before, he returned to the study of seawater desalination.

Rubbing his greasy hair, it was clear that Professor Grossman was stumped by the question.

Like Liu Feng, Grossman is not satisfied with continuing his research on polyamide composites, because he also found that no matter how much he continues to go deeper in this area, the cost of reverse osmosis membranes will always remain high.

Therefore, he had the idea of creating a new and inexpensive desalination treatment material, and he already had a general direction.

At this moment, there was no good solution to the difficulties encountered in the experiment, so Grossman simply stopped thinking and wanted to make a cup of coffee to relieve himself.

But at this moment, he suddenly received an email from Nature Chemistry in his mailbox.

"Huh, polyamide composite reverse osmosis membrane?"

Looking at the email on the screen, Professor Grossman, who had just stood up, sat down again, a look of interest on his face.

He tossed the cup aside, then turned to his assistant and ordered, "Danucci, make me a cup of coffee!"

“OK，Doctor！”

The white guy with long bangs got up and walked over to Professor Grossman, took his cup and walked outside, and after a while, he heard the water dispenser gurgling, and then the white guy named Danucci walked in and brought the coffee to Grossman's computer desk.

Professor Grossman enjoyed his coffee as he continued to browse through the paper he had downloaded from his email.

To be honest, the research results on polyamide composite materials over the years, not 50 articles but also more than 10 articles, although last year he did not continue to study in this area, but he believes that continue to research, can not make a breakthrough, want to reduce the price of desalination reverse osmosis membrane to the point that it can be promoted on a large scale, it is almost impossible, can reduce 3%, are already very shocking results.

Even the year before last, he only reduced the cost by about 2%, but there was no significant improvement in the efficiency of desalination and desalination rate.

And these papers, yes, are not just one, they dare to say that they have improved the efficiency of processing and several other influencing factors, and even generally reduced the cost of 10%~20%, and one paper even reduced by 30%!

It was hard for him to imagine! What kind of material did the great deal come up with? Professor Grossman was very interested.

Let's take a look at the first author of the paper, Feng Liu.

Feng Liu? Who doesn't know you at all?

Grossman frowned, it was obvious that he didn't know much about Huaguo's experts in this area, but at least he still knew the name, and there was no one named Feng Liu!

Well, he's heard of this person, and he's been a great stubble in the field of functional intercalation materials, so he can barely read the next papers.

Read on.

As the paper progressed, Professor Grossman's facial expression changed from a slight interest at first, to a complete engagement, and finally to a shock, his mouth wide open, and his eyes revealed disbelief.

"Through the polymerization of a variety of aromatic compounds, the resistance of materials to free chlorine can be effectively improved...... It can effectively reduce the pressure required during transmission and reduce energy consumption...... This, this, how did this guy come up with it?!"

There is no doubt that these papers are relatively novel, and there are no errors in the data and tables in them, according to his previous experience in polyamide composites, there is no obvious falsification in the papers, that is, these papers should be feasible!

Moreover, what surprised Professor Grossman the most was that, judging from the results of these papers, this guy has almost made a polyamide composite reverse osmosis membrane! In the future, not to mention that other teams have developed polyamide composites that exceed these results, it is almost difficult to achieve half of the effect of these materials!

If these papers are true, once they are sent, I don't know how many people's jobs will be smashed, Professor Grossman shook his head, this guy is simply going his own way, so that others have no way out!

Thinking of this, a feeling of happiness suddenly welled up in his heart.

If he had continued to study in this area, I am afraid that among the people who have been smashed their jobs, there will be one more self, at that time, he wasted time and effort to completely waste everything, not to mention, it is impossible to make achievements in the field of solar thermal energy storage of new materials!

It seems that God still favored him!

With a sigh of relief, Grossman couldn't help but make a cross on his chest.

Fortunately, Professor Grossman thought about it for a long time, but he still couldn't easily draw conclusions, and he couldn't confirm the authenticity of the paper just by looking at the data.

Therefore, Grossman turned his head and ordered the assistant not far away: "Danucci, I'll send you a few copies of the experiment to your mailbox later, and you can order it all to go down and do it all." Isn't there no progress in our experiments, OK, let's put it aside for the time being, maybe it's a good thing!"

“OK，Doctor！”

Watching Danucci walk out of the office, Professor Grossman smiled and nodded.

Danucci is also a doctoral student he has taken with him, and his research is naturally in the direction of materials, and he has been with him for two years. Speaking of which, the year before last in the polyamide area of the research results were released, this guy also made a lot of contributions, and last year's research on new solar thermal energy storage materials played a pivotal role.

Therefore, his evaluation of Danucci is that he is highly talented, diligent, able to calm down, and willing to work hard;

These papers, the experiment is not a very difficult thing, it can be verified within two or three days, and when the time comes, he will come to see if these materials really have such an exaggerated effect!

As half a colleague, Professor Grossman is already waiting to see what happens.

While Professor Grossman's team was verifying the experiments in Liu Feng's paper, Liu Feng was already standing in the auditorium of the school, wearing a bachelor's gown, and was receiving the graduation ceremony held by President Tan for him.

"From today onwards, you have become a glorious bachelor, moreover, you are also a double bachelor of physics and chemistry, I hope you can inherit the indomitable spirit of the University of Chemical Technology, Hongde erudition, chemical education genius! Come on! young man!" President Tan also wore a crimson doctor's gown and a gilded doctor's hat on his head, solemnly handed over the graduation certificate and degree certificate to Liu Feng's hands, and made a heartfelt speech.

"Thank you, principal, the students will definitely live up to their mission and carry forward the spirit of our university!" Liu Feng took the certificate, and then solemnly returned the salute.

So, time was frozen in the year when he was 18 years old, and in that year, the scholar was angry and scolded Fang Xuan......
