Chapter 198 Radu: I have a friend...
Surprise.
Radu could hardly count how many times today he had associated himself with this joyful word. He always felt that he had bad luck, but his bad luck seemed to be dispelled by the sun the moment he saw Haroldt.
I have always wanted to try new potions, but I have not had the formula, so progress in this area has been stagnant.
This is just... I've never craved so much before coming here.
He moved his lips and thanked Harold calmly:
"Thank you, teacher. I feel that the notebook will be very helpful to me. I will study it carefully and apply the knowledge in it to my experiment."
Harold smiled and nodded in response.
That's because I'm going to put the formula for sulfuric acid on page two.
As long as you start studying that "old notebook" and try using the chemicals recorded there, you will soon find that the second chemical recorded there will make your experimental progress take off.
I just need to recall it carefully after I go back, write down all the formulas I know, as well as the periodic table and chemical equations, and let Radu figure it out slowly.
I feel that with his ability, he will be able to organize and publish these things soon. This will be a milestone in the development of Teyvat chemistry, and I will get more practical chemical agents.
Harold felt that the future was so bright that he wanted to shout happily, "My disciple Radu has the potential to be a great sage."
Well... the craftsmanship of making old things needs to be improved.
The bicycle blueprint was originally placed in the office of the Miaolun Sect sage. This "old notebook" that records the periodic table will probably be placed in the office of the great sage, and no one can be notified of the clues.
Harold pursed his lips and continued with the previous topic:
"I might also be able to give you some advice on how to collect the 'Jia Rang Heart'."
Radu immediately straightened his back and made a gesture of listening attentively.
"In my hometown, in the laboratory, scholars will choose different methods to collect gases according to the different properties of the gases," Harold said.
"For gases that are easily soluble in water, they will use the air exhaust method and determine the position of the conduit in the gas collecting bottle based on the quality of the gas.
For gases that are insoluble in water and do not react with water, they use the water displacement method.”
Radu was confused. What was the teacher talking about? What was the "air exhaust method"? What was the "water exhaust method"? He had never heard of it.
Radu's reaction was within Harold's expectations. In the late 18th century, scientists on Blue Star proposed the concept of draining water and collecting gas.
But in Teyvat, because of the blessing of the mysterious side, in terms of chemistry, the scholars here do not seem to pay much attention to the standardized operation of experiments.
So Harold opened the notebook he brought with him, flipped to the middle page, and showed Radu several schematic diagrams he had drawn in advance.
"This is drainage gas collection. Put the gas collection bottle filled with water upside down in the sink like this..."
Harold explained in detail the operation and precautions of two common gas collection methods in the laboratory. Radu listened carefully.
With the diagrams and explanations drawn by Harold, he immediately understood the benefits of using these methods to collect gas.
He couldn't help but feel annoyed inside. It was such a simple method, why didn't he think of it before?
Harold: "Of course, there are more ways to collect gas. For some gases with special properties, scholars in my hometown also use oil drainage method, salt water drainage method, etc.
The operation method is similar to the drainage method, you only need to replace the liquid in the sink.
As for the specific choice... we must first understand the properties of the gas,
For example, your 'Jia Rang Heart', whether it is soluble in water, the difference in quality with air, etc., and then choose the appropriate collection method. "
"...It is insoluble in water and does not react with water, so I should collect it using the drainage method?" Radu asked Harold uncertainly.
"Perhaps, you can give it a try." Harold said with a smile, "But this is only applicable in the laboratory, that is, when only a small amount of 'Jia Rang's Heart' is needed."
After all, industrial production of ethylene is much more complicated.
"Well, this helps me a lot. Thank you very much for your advice, teacher."
Radu bowed to Harold. He felt that he had benefited a lot today. Not only did he become Harold's student and get investment for the project, but he also learned a lot of new knowledge and gained a lot of inspiration.
Harold had never seen his operating procedures, and based only on his experimental records and descriptions, he pointed out the problem as soon as he opened his mouth.
He even felt that he had learned more in just a few minutes today than he had in the three or four years he had spent tinkering in the laboratory.
He really is worthy of being a famous figure in our academy!
Radu was extremely impressed and felt extremely humbled that he had the honor of becoming such a talented student.
"It's okay. I'm glad I can help you. This is all I can think of for now." Harold nodded slightly and said with a smile.
"We have said everything we wanted to say. The next time we meet will have to wait until you finish your studies. Do you have any other questions?"
Radu hesitated for a moment and asked, "Teacher, if my research makes any progress during this period, can I report to you at any time?"
"If it's something you think is important, you can find Dolly. She knows how to contact me." Harold replied.
After receiving such a reply, although Radu felt a little disappointed for not getting Harold's contact information, he was also happy that he was willing to spend time on him.
"Also, can I...can I know your admissions criteria?"
Radu himself felt that this question was a bit too much, but when he thought of his good friend Elias,
The person who has always been by his side to support and encourage him said that he wanted to choose the same mentor as him and join the same research team. Radu finally asked this question.
Strong, free. Two words flashed through Harold's mind.
But he replied calmly: "Excellent character, excellent grades, and certain teamwork skills."
"I have a good friend named Elias. I personally think he meets your standards. Can you consider accepting him as a student?" Radu asked.
Buy one get one free? That's great! And Ilias is also an old acquaintance. He has been on my candidate list since the beginning.
Harold thought.
He paused and said calmly:
"Maybe my attitude today has caused you to misunderstand. I have high expectations for my students.
The reason why I didn't ask for your specific information is because I am optimistic about your research, and I have made a lot of preparations before coming here.
I know you are an honest scholar and have heard of your qualities.
But regarding the person you recommended...I'm sorry, to be on the safe side, I need to read his personal profile and college evaluation in detail before I tell you my answer."
"It's good that you are willing to consider it... He is really excellent! You will know once you read his information," said Radu.
Harold's words just now made him more certain that this was a very responsible mentor, and it also gave him some confidence as he had always been suppressed and ridiculed in the academy.
Harold made a "stop" gesture again and repeated, "I will go look through his information and give you an answer after reading it."
