Chapter 218 Ultrafiltration
"Professor Wu, you are here!!"
"Good morning, Professor Wu!"
As Wu Tong walked towards the laboratory, the experimenters he met along the way greeted him respectfully one by one. After several days of settling down, the holiday did not affect the spread of news. Now, the news that Wu Tong was specially appointed as a full professor by Peking University has been widely known to everyone.
Shock and as if it was natural, they naturally changed to a formal honorific when they saw Wu Tong. They had imagined calling him Professor Wu many times before, and now that it had become a reality, they were not at all uncomfortable.
The people who had signed the confidentiality agreement and conducted experiments with Wu Tong felt that it was natural. The school finally responded! Wu Tong was promoted to the rank of professor. Finally, they no longer had to be students of such a god and were ashamed to lift their heads!
Although Wu Tong, who is much younger than them, has already graduated and has a formal professional title, they are still not good looking. But, what is that called, they are not in the same line, so let them cover their ears and steal the bell for a while.
If one is one point superior to ordinary people, they will envy him; if one is ten points superior to ordinary people, they will admire him. Then, if one is as superior to ordinary people as Wu Tong, then there is a world of difference between gods and humans. They do not compare themselves with gods!
"Professor Wu, what do you need me to do?" Ruan Chengxu followed suit, but compared to the others, as a junior brother in the same school, his tone was more joking.
However, he had to hold on tight.
When they first met, the junior sister was a freshman and he was a sophomore. Now, his graduation thesis is almost finished, but the junior sister has graduated before him. Even though he knows that he can't compare with a genius like the junior sister, the gap is still obvious and heartbreaking.
"Brother Xu, you are teasing me too!" Wu Tong laughed, "Help me make some molecular materials, Brother Xu!"
Wu Tong simply changed the subject. People around her would be surprised at her appointment for a while, but they would eventually return to their normal state.
"Okay, Wu Tong, you arrange it!" A teasing was enough. If it really was Professor Wu, it would be a matter of estrangement between fellow students. Ruan Chengxu was still very reliable.
To be honest, the exclusive research institute for the junior sister has already begun construction. As her senior brother, he should quickly perform well and then get a chance to join the junior sister's research institute. He would be a fool if he didn't seize the opportunity with such a glittering backer.
"What materials are you going to synthesize? What preparations are needed?" Ruan Chengxu asked carefully, doing the preparations that an assistant should do. This was not flattery, but the look that must be followed by the boss.
People who need to be poked before they can move will find it difficult to make a name for themselves in the laboratory, unless they are top geniuses like Wu Tong.
"A special silicide, starting from silicon monoxide. Let's first synthesize all the existing silicon oxides!" Wu Tong was unambiguous and gave a clear direction.
Of the four research directions, Wu Tong decided to first complete the ultrafiltration purification membrane, which already had a foundation. This was an idea she had wanted to pursue before, but it accidentally collided with the PL-15 fuel derivation direction and resonated with it, resulting in the derivation of a special silicon oxide membrane, and the development of N18 and N24 ahead of others.
Wu Tong got up early and made some deductions. He felt that the direction of ultrafiltration purification membrane should still be based on the previously derived silicide and graphene film. This time, the silicon oxide prepared by Wu Tong was not limited to directional hexasilicon oxide, but multiple silicides.
These were all basic materials. With the help of Ruan Chengxu, who had proficient basic skills, Wu Tong made rapid progress. In one morning, a series of preparation processes were completed and Wu Tong obtained some silicon oxide materials.
After the preparation was completed and lunch was had, Wu Tong continued the experimental process. She performed this step personally, observing the silicon oxide molecules one by one under a transmission electron microscope.
While observing, Wu Tong was making deduction records. In his mind, his thoughts were running at high speed, and the accumulated knowledge became a booster, allowing Wu Tong to determine the direction of progress and improve step by step.
In the end, Wu Tong spent three days selecting seven silicon dioxide atoms connected together and superimposed them with a special co-bonding effect, and finally obtained a new molecular material.
Wu Tong called it high-density silicon heptoxide. He deposited it on the prepared graphene film, cut off the excess irregular parts of the edge deposition, and prepared a high-density silicon heptoxide film.
According to Wu Tong's deduction, this high-density silica heptoxide has a powerful filtering effect and is energy-incompatible with foreign elements. In principle, it only allows water molecules to pass through. It can be called a high-energy water molecule filter and is an ultrafiltration purification membrane that truly meets her expectations.
"Is it successful?" Ruan Chengxu looked at the ultrafiltration purification membrane in front of him, which was shining like a black diamond in his eyes, and his voice was a little unbelievable. Even though it was not the first time for him to cooperate with Wu Tong in an experiment, he was still shocked by the accuracy and speed of Wu Tong's experiment.
Without Wu Tong's experiments, it would basically be trial and error, trial and error, failure, then choosing a direction, and failing again. If one gets lucky and finds a feasible direction within hundreds of times, then everyone would thank God and hold a celebration party.
However, following Wu Tong's experiment, Wu Tong gave directions, and they prepared according to the instructions. Wu Tong deduced the next direction, and he continued to synthesize according to the instructions. After completing the step-by-step operation as if it were a precise assembly line, the experimental results were successfully achieved. Such smoothness and precision made them envious and wanted to cry.
"It was only partially successful!" Wu Tong installed the successfully prepared ultrafiltration membrane on the water purification instrument she had temporarily modified, turned on the switch, turned on the power and water, and soon, a 500 ml cup of transparent water liquid appeared in the transparent sub-storage container, and a little dirty solution in another storage container.
"Conduct sample test!" Whether the ultrafiltration oxide membrane is truly successful still needs this step to be confirmed. Soon, the sample test results came out.
Ruan Chengxu's eyes were full of excitement. "Wu Tong, the transparent liquid sample No. 1 is confirmed to be a pure water body that can basically be identified as pure water. The turbid solution No. 2 contains trace amounts of bacteria, trace amounts of heavy metals such as mercury, arsenic, lead, cadmium, and trace amounts of various organic and inorganic substances!"
After seeing the test results of the mixed solution, although he knew that the amount was extremely small, Ruan Chengxu still felt that he would not want to drink natural drinking water for a few days. Or, he could learn from Wu Tong to assemble an ultrafiltration water purifier and filter the water for drinking.
As for drinking pure water for a long time, it is not good either. You can just add beneficial trace elements by yourself.
They are involved in materials and basic chemistry. They know the appropriate ratio of various trace elements and water that are beneficial to the human body! It doesn't matter if you don't know. Just do a few more experiments.
