Dr. Zhong took it and looked at it. Among them was electrolytic silver, a secondary controlled substance. Silver is not rare, but electrolytic silver is. [No pop-up novel website] The electrolysis industry of non-ferrous metals has not yet started, so use more and less of this stuff. However, once the bayonet in the power industry is solved, electrolytic copper and electrolytic silver will not be a problem.
The things below the list are more powerful. The items listed are all equipment and consumables under first-level control. It can be said that they will not be self-produced within five to ten years.
According to regulations, after he signs this type of professional materials as a professional leader, unless the inventory really reaches the "red warning line" standard, the Planning Institute will directly approve the receipt. In comparison, it seems like a heavy responsibility. He read it several times, but did not dare to ask rashly, such as: "These things are really necessary to use": in this profession, Dr. Zhong is basically on the same level as the naturalized people on the roadside. Talking too much will inevitably reveal your timidity. He thought about it and decided that he still had to trust the professionals. Besides, this project was indeed very important. Once developed successfully, it would not be a golden finger, but the black technology of the 17th century.
"I agree." Dr. Zhong took out his name badges from his pocket and stamped them one by one in front of her. "Tomorrow I will give them to my secretary and send them to the Planning Institute -"
"If you think it's okay, I plan to go to the Planning Institute in person with these documents tomorrow - my time is too tight and I can't wait to go through the official document process, and there are some things that I have to pick out myself to feel at ease."
"It's okay." Zhong Lizhi nodded, "But the formalities for your document are incomplete, so I'll give you a note first. You go with the note and the documents, and then I'll send someone to go through the formalities."
"Thank you very much." Ge Xinxin said calmly and generously.
Dr. Zhong took out a notepad on the letterhead of the Ministry of Science and Technology from his briefcase. I took out the hero fountain pen and started writing rapidly. Finally, there was a signature and date.
Ge Xinxin took it and blew it carefully, then smiled and said, "Thank you. You are such a good leader."
"You're welcome." Zhong Lizhi stood up and said goodbye, "Once your project is successful, many people in the industry will be grateful for your kindness." He said jokingly
"Don't take it seriously. It's all the result of everyone's joint efforts." Ge Xinxin said as she carefully put the document into her pocket, "I'm going to do an experiment, please go slowly."
Ge Xinxin returned to her laboratory. Her two naturalized "trainee experimenters" were still sitting on the bench in the corridor outside the door, waiting for her. Both of them are girls. Ge Xinxin wanted to avoid trouble at work on weekdays. All the experimenters under his command are female, and they are all over 1.60 meters tall - the experimental equipment in the laboratory is made according to the average height of the elders, and it will be difficult for naturalized civilians who are too short to use it.
She unlocked the door with her key: her private laboratory number was No. 4. It belongs to the "special laboratory". Most of the experimental equipment configured inside comes from another time and space. Access is strictly controlled. Except for the "trainee experimenters" personally brought by the senator, other naturalized citizens are not allowed to enter.
Not only that, when the elders are not present, the naturalized civilian experimenters cannot be present either - the first thing is to ensure safety. Laboratory safety issues. Even professionals in the 21st century often make brutal mistakes, let alone the natives of this time and space.
A naturalized citizen who can be an "assistant" is not only one in a million, but also one in a hundred. Death and disability are not as easy to replace as losing a laborer on a construction site.
Secondly, once an accident occurs, the laboratory equipment and medicines will be lost. Some of them are "more valuable than gold" - there is no place to buy them if there is gold: the commonly used 1/1000 balance alone is not the current equipment of the Senate. industry can produce.
Ge Xinxin walked into the laboratory and inspected the tidying up work done by the naturalized civilian laboratory workers: classifying the waste liquid according to the labels, washing the instruments, and tidying up the laboratory tables. After confirming that everything was OK, he looked at his watch and said:
"You can get off work and come to the laboratory on time at seven o'clock tomorrow morning - you will work for Mr. Xu tomorrow. I have to go out for something."
It is now eleven o'clock in the evening - naturalized civilian experimenters do not have commuting time and work according to the veteran's schedule. Meeting a veteran like Ge Xinxin. That basically only leaves time for sleeping, eating and going to the bathroom.
After letting the trainee experimenter leave, Ge Xinxin sat on the chair for a while - she was already very tired, it could be said that she would fall asleep immediately when she lay down, but she still had to sort out her ideas for applying for the project first.
Early the next morning, Ge Xinxin got up early, put an empty backpack on her back, and took her usual handbag and set off. She boarded Ma Niao's commuter train all the way to Bairen, then showed her ID at the ticket office of Bobu Station and bought a ticket to Gaoshanling Station.
The track from Bairen to Gaoshanling has just been paved. Although everyone can ride it, not everyone can buy the ticket from the terminal to Gaoshanling Station: only elders and naturalized citizens with special passes Only then can you buy tickets for Gaoshanling Station.
Ge Xinxin successfully arrived at the Controlled Materials Warehouse of the Planning Institute in Gaoshanling and quickly received the various controlled materials she applied for.
"Ge Xinxin, what are you doing with all this silver? And you also need to electrolyze pure silver. No one is interested in this except for people who are interested in electricity. And gelatin, is it possible for you to make cold dishes or jelly with this stuff? "In the Materials Office of the Planning Institute, Sun Xiao, who was on duty, asked strangely while stamping the application form handed over by Ge Xinxin.
"Un secret qui rend une femmefemme." Ge Xinxin put her right index finger on her lips, said this with a chuckle, then put the stamped application form into a binder and put it in her handbag, turned around and walked out of the office, leaving only Sun Xiao stared blankly at the door and muttered to himself: "Huh? Is this perfume? Why is it still in stock after two or three years? Who is this girl?"
Taking the gelatin and silver with her, Ge Xinxin returned to her laboratory. She first took out a set of 24# distillation equipment—despite a lot of effort, the glass factory could only produce standard mouth instruments of 14# and above. Micro and semi-micro instruments are still “under development”. But for today's work, the 24# equipment is just right. She poured a 500ml bottle of concentrated nitric acid into a 1000ml round-bottomed flask, added a few broken porcelain pieces, and then distilled it on an oil bath. Cut the 115-125c fraction, which is 68% concentrated nitric acid with most metal ions and other impurities removed. Add 100g of chopped pure silver to the receiving bottle and change it to the reflux device of the water bath. Ge Xinxin then filled out an overnight reaction form and placed it in front of the device. He took off his white coat and hung it on the hook by the door.
She boarded the commuter train leading to Bairen City to have dinner - tonight she planned to go to a merchant restaurant to eat something good to improve her life, and by the way, she would go to the cooperative to buy some daily necessities, although the goods there were far away from her own. It's still far from the requirements, but at least a lot of them are barely usable.
At 8 o'clock in the evening, Ge Xinxin returned to the laboratory, stopped the reflux and transferred the solution to an ice bath to cool down. When she turned on the water pump, a loud noise unique to this space-time machine rang out. She couldn't help but frown: "Really, the machinery factory keeps saying it wants to improve but never takes any action." Pour the cooled reaction solution and solids into a cloth lined with filter paper. Filter through a funnel, rinse with 95% ethanol 5 times and drain. Collect the obtained powder in a brown jar labeled with silver nitrate, open the cap and place in a desiccator. She then weighed 10g of gelatin and dissolved it in 350ml of hot water, added 32 degrees of recrystallized potassium bromide from horsetail and stirred evenly, keeping it at 55c. Weigh another 40g of silver nitrate and dissolve it in 400ml of warm distilled water. Then she prepared 40g of gelatin without excess water.
After all the solutions were prepared, Ge Xinxin turned off all the lights and closed the curtains - in the 17th century, when there was no light pollution at night, just closing the thick baize curtains would be a perfect darkroom. Turning on the flashlight covered with red paper, she started the next step of her work. Slowly pour the silver nitrate solution into the potassium bromide-gelatin and stir continuously at 55°C for 10 minutes. Then add the prepared gelatin, stir well and heat for half an hour. Ge Xinxin put the beaker into an opaque box and covered it, then used a flashlight to find the light switch and turn on the light. She put the label on the box and put it in the cabinet. Then she found the naturalized citizen on night shift and asked her to dispose of the waste liquid and clean the instruments according to the regulations.
"It's already 10 o'clock. Let's just finish this tonight." Ge Xinxin sighed after looking at his watch. She left the laboratory and paid attention to the veteran experimenter on duty. Returned to the dormitory building on one side. This building was specially built by the General Office for the veterans working in the Central Laboratory of Heavy Industry. Each one has an office with sleeping quarters. This is much better than the treatment in the 21st century - what she and all chemical industry employees were used to, it was just a folding chair in the office.
As a rare female veteran in the laboratory, she has a separate bathroom in her dormitory. The bedroom is decorated in a feminine style and is very cozy, with no so-called "industrial" style at all. A small handmade Persian rug of pure wool is spread on the bamboo floor. The walls are hung with meticulous flower-and-bird paintings bought during the trophy auction, a vase-turned-table lamp stands on the solid wood bedside table, and the single solid wood bed is covered with white and blue calico bedding - this is the most beautiful thing that the Ministry of Light Industry can come up with. Pure cotton bedding. The IKEA-style solid wood wardrobe made by the carpentry factory holds her various clothes, and there are more than a dozen bags and handbags placed on the special partitions - several of which are fake A cargo LV bags from Lando's ship. They are carefully used. The ones wrapped in paper are placed on the top layer, and the rest are local goods produced by the Ministry of Light Industry. (To be continued...)
