Chapter 5 Eating
"Gloves are in the lounge and the laboratory, you go to the second closet and put them on." Ai Guichu seemed not to notice Ai Gong, without raising her head.
When Ai Guichu said this, Ai Gong nodded subconsciously, moved his eyes away from Ai Guichu's hand, and walked to the closet stiffly.
Different from medical gloves, the gloves worn in the laboratory are thicker and green in color. Ai Gong obediently took out a pair and put them on, then walked back.
"The experiment done in the freshman year should teach you how to wash the instrument, right?" Ai Guichu raised his eyes.
Ai Gong looked at Ai Guichu's movements, and thought about her usual behavior of washing instruments, and said with some hesitation: "That...all the freshman year were inorganic experiments, this is organic..."
At this point, Ai Guichu nodded, stopped what he was doing, and turned to look at Ai Gong: "If there is anything you don't understand, just ask."
"Oh, oh..." Ai Gong nodded flattered, looked at the instruments in the basin, and then at the faucet with "CW" (clearwater)... Is organic experiment so rough... Even distilled water is not needed ?Wouldn't the metal ions left behind affect the reaction?
Seeing Ai Gong staring at the faucet without speaking, Ai Guichu probably understood what Ai Gong wanted to ask, but his cute and dumb look really pleased him a lot. Ai Guichu folded her arms and admired it for a long time before taking her time Open your mouth.
"Metal ions in water are almost negligible for experiments, and metal ions have always been insoluble in organic reagents. And instruments such as test tubes are never reaction vessels in organic matter."
Ai Gong nodded knowingly, looked at it for a long time, but didn't speak.
Seeing that Ai Gong was so "shy", Ai Guichu smiled helplessly, reached out to pick up the instrument in the basin, and said, "Well, let me wash it for you, remember how to do it."
Ai Gong nodded quickly.
"...For an instrument with a thin neck and a large belly like a flask, bend the test tube brush when the test tube brush enters halfway..."
"The test tube needs to be brushed at least ten times..."
"The reaction tube mainly washes the body of the tube and the piston..."
……
After washing the instruments one by one, Ai Gong listened to Ai Guichu's explanation and nodded continuously.In the teaching experiment, the teacher usually doesn't know how to wash the instrument, and they all rely on their own groping. Now listening to Ai Guichu's detailed explanation, Ai Gong can't help but feel a little distracted-if this is a girl... please marry me what!At least you can rest assured about washing dishes in the future! ! !
The number of instruments is not many, but the types are more. After talking about it again, the instruments are almost washed.Ai Guichu cleaned the washed instruments one by one, and sent them all to the oven, and this was the end.
Seeing Ai Gong's concentration, Ai Guichu said inadvertently, "Is your girlfriend sitting next to you in class today?"
Hearing Ai Guichu's question, Ai Gong blinked blankly, and quickly shook his head after realizing it: "No, no, he's not my girlfriend, it's Shi...a friend I know."
Ai Gong remembered that only the people in the dormitory knew Sun Mistress's identity as a girl, so she quickly changed her words.
"Oh..." Ai Guichu responded meaningfully, and glanced at Ai Gong's lower body.
Ai Gong didn't notice it, and was guilty of lying just now.
Ai Guichu took off her gloves and threw them into the trash can, raised her hand to look at the watch on her wrist, and said, "It's time for lunch, come with me."
Ai Gong nodded and responded.
Follow Ai Guichu out of the laboratory and back to the lounge, and change his clothes.I thought the two would be separated, but Ai Guichu still let him follow.Ai Gong blinked her eyes, thinking in her heart that there were so many people in the cafeteria at noon, so she should throw him away when she got to the cafeteria.result……
"Uh...professor, where are we going?" Ai Gong sat in the co-pilot and watched Ai Guichu drive the car out of the school.
Ai Guichu swiped the parking pass and continued to drive seriously, saying, "I don't care how old you are, just call me Guichu."
Uh... Ai Gong's expression was stiff, and she opened her mouth tentatively: "Gui Chu...brother?"
Ai Guichu glanced at him with a half-smile, and replied, "I can't swallow the food in the school cafeteria. My house is next to the school."
...Does this mean going to his house for dinner?Ai Gong burst into tears.It means that if you eat such a meal, you will definitely suffer from indigestion!
Ai Gong's expression changed from red to white a few times, feeling that the atmosphere was a bit dull, so she spoke cautiously again, and said, "Teach... Is Brother Gui Chu married?"
"No." Ai Guichu glanced at the red light ahead and stopped the car.
"Oh... so what is the direction of Gui Chu's research now?" Ai Gong asked out of context.
Ai Guichu smiled, put one hand on the steering wheel, and said casually: "Oxidative coupling and so on, by the way, study and optimize the production chain of coenzyme Q10 (*the author has something to say, there is an explanation in it)."
"..." I didn't know it, and Si Azhai said that he only knew APTX4869 (the shrinking potion in Conan).
Seeing Ai Gong's bewildered face, Ai Guichu looked away, started the sports car, and said, "Now you are not involved in these fields. Before your senior year or even your master's degree, all you have to do is to repeat the previous literature."
"Oh..." Ai Gong responded, expressing that she could accept it.
After about half an hour's drive, the two finally arrived at their destination.
The community Ai Guichu lives in is a high-end residential area near the university town. Ai Gong once passed by with his buddies and even got rich. He didn't expect that he could go in today to open his eyes.
Followed Ai Guichu into the room, and changed into slippers under the other party's signal. Ai Gong stepped on the soft floor and sighed that Ai Guichu was really a clean freak—is it really good to see all white?
White sofa, white coffee table, white curtains, white carpet, white bookcase... Nima, there is no visual fatigue!
Of course, it was impossible for Ai Gong to say it.
Ai Guichu asked Ai Gong to sit freely, and threw a thick document from nowhere, and went into the kitchen.
Ai Gong casually flipped through a few pages, and the full text of tadpole words made him dizzy. He closed the book and looked around for a long time before he realized that Ai Guichu was actually cooking!
This world is fantasy!
The corners of Ai Gong's mouth twitched, and she walked quietly to the dining room, looked at the kitchen inside, and saw Ai Guichu with her back turned to him, cutting something.
QAQ I suddenly feel a lot of pressure after eating the meal made by the boss!Ai Gong quietly walked back to the living room, holding the documents in a daze on the sofa.After eating the other party's food, do I still want to invite him back... Seeing the other party's economic level, I can't afford to invite him...
Ai Guichu didn't know Ai Gong's thoughts, otherwise, if he knew his thoughts, he would pay him directly, so why should he be so distressed.But... feed the other party first before feeding yourself... Ai Guichu will not admit that he has such thoughts!
I don't know how many dishes Ai Guichu cooked. Anyway, when Ai Gong had already identified the language as English, German, French or Spanish with the documents, Ai Guichu came over wearing an apron and asked him to eat.
Ai Gong immediately followed Ai Guichu to the restaurant.
There are several hot dishes on the table, such as leek eggs, fried lamb with onions, asparagus and shrimp balls, sea cucumber and tofu soup...
Then I heard Ai Guichu say something like "they're all home-cooked food"... the cafeteria was so weak in an instant!Pick up a chopstick of mutton and put it in your mouth... Mom is so weak in an instant!
Why isn't the professor a girl!Propose!
After cleaning up the food in front of him, he raised his head and realized that Ai Guichu had left the table at some point and came out with a small piece of pudding.
Ai Gong watched helplessly as Ai Guichu put the pudding in front of her, reached out to touch her belly, and pushed the pudding away with great reluctance, and said, "Teach...Brother Gui Chu, I'm already full."
Ai Guichu pushed the pudding back and said, "Take it to the lounge to eat in a while, I'll clean it up first."
So Ai Gong obediently held her beloved pudding and watched as Ai Guichu packed up the tableware and went into the kitchen to wash the dishes.
This kind of wifely attribute...Professor, why aren't you a girl!Otherwise, suitors line up to the Milky Way!
Ai Gong sat obediently in the living room, looking at the pudding on the coffee table, flipping through the literature in his hand, a little absent-minded.
However, why... I always feel that the living room is very hot... Is the air conditioner broken... QAQ
The author has something to say:
Distilled water: Pure water prepared by distillation is called distilled water. 1. The water in nature is not pure, and usually contains calcium, magnesium, iron and other salts, as well as organic matter, microorganisms, dissolved gases (such as carbon dioxide) and suspended solids.The non-volatile components can be removed by distillation.Distilled water with higher quality can be obtained with the following measures. ① Drain the initial fraction (accounting for about 20% of the raw water), because the volatile components are mainly concentrated in the initial fraction. ② Drain the residual part (accounting for about 20% of the raw water), because many non-volatile components are concentrated in the residual water. ③Add certain substances to facilitate distillation.For example, adding NaOH can make CO2 in water become a low-volatile component, and adding KMnO4 can oxidize organic matter in water.One of the quality standards for distilled water is that the salt content is generally around 1 to 5 mg/L.Because the salt content in the water decreases and the resistivity of the water increases, the purity of the water can be measured by measuring the resistivity of the water.The resistivity of distilled water is required to be around 0.1×106Ω·cm (ohm·cm).Distilled water is distilled a second time to obtain double distilled water, which has a higher purity.Distillation consumes a lot of energy, and now the ion exchange method is widely used in laboratories and industries to obtain pure water.This water is also called deionized water.
However, Meizi said that the deionized water used in her laboratory is directly the drinking water of the water dispenser
Coenzyme Q10 is a substance in high-end cosmetics. A bottle of cosmetics containing this substance is at least [-]. If there is less, there must be fakes. At present, there are only two manufacturing methods in the world, both of which are mastered in Japan.One is the raw material of tobacco purification, and the other is fermentation.
