Chapter 5790: OK, average, not involved

The explosion experiment is over.

Qiao Nian returned to the third laboratory.

The black people, who had not seen her for a long time, all gathered around her.

Others were embarrassed to ask, but the black man, who was carefree and cheerful, asked out of curiosity: "Chemist, you went to the first laboratory, how was their laboratory? How was the blasting experiment? In what part did you participate." "

Qiao Nian was thinking about something and walked over without turning his head. His eyes were indifferent: "It's okay. Average. Not involved."

The black men looked at each other and followed them: "What do you mean you didn't participate? Didn't you just apply to participate in their session?"

 Qiao Nian put her bag away, closed the cabinet door, and turned around. Facing a dozen pairs of curious eyes, she paused and said with a lack of interest: "Well, I took a look around."

"Damn!" The black man punched the table: "They are going too far! This is bullying! I will go to them to argue!"

Bethiya came in just in time and grabbed him: "Come back."

She grabbed the collar of the black man, who was 1.9 meters tall, and pulled him in like a little chicken. Bethea let go of her hand, folded her hands around her chest and looked at him: "Did the chemist let you get ahead? Stay here honestly and don't give in to the chemistry." The teacher is causing trouble!”

“I…” The black man was so angry that he suddenly raised his head.

Bethia ignored him, walked straight to Qiao Nian, patted the girl's shoulder, and asked in a low voice: "Are you okay?"

"Very good." Qiao Nian raised her eyebrows frivolously, raised her chin boldly, and looked over her shoulder in the direction of the black man: "Thank you just now."

Bethea followed her gaze back and met the black man's big eyes. She felt relieved immediately and looked back at the girl again and said, "It seems you're fine." Before Qiao Nian could answer, she insisted, "Chris and the others will This is how I was treated when I went to the First Laboratory, and they didn’t target you.”

 Qiao Nian nodded indifferently to show that she understood: "I understand. They just look down on everyone equally."

“Pfft.” Bethea laughed out loud, and then pretended to calmly admit it: “Yes, everyone here is rubbish.”

 Qiao Nian shrugged her shoulders, apparently not affected by the cold reception she received in the first laboratory. She turned around and asked Bescia, "Is there a separate laboratory?"

“What do you want a separate laboratory for?” Bethea followed and immediately said: “Yes, I will apply for one for you.”

Qiao Nian said easily: "In the next few days, I hope to stay in a separate laboratory for retreat. If it is not necessary, it is best not to disturb me."

“?” Bethea’s expression was startled.

 Qiao Nian turned around and looked at her with dark eyes: "...I will explore the preparation method of plutonium-239 in the next few days."

Four days later.

Qiao Nian called Feng Yu in a separate laboratory.

“So if I add boron to plutonium-239, it will work.”

Feng Yu said: "Well, in theory it is effective, but the effect will not be too obvious. If you want a good effect, you may need boron carbide B4C."

Shi Fu also said seriously next to him: "The isotope 10B of boron has an extremely high thermal neutron absorption cross-section and is an excellent neutron absorption material. Boron carbide (B4C) combines the neutron absorption ability of boron with the excellent properties of carbon materials. Performance, composite materials such as boron carbide polyethylene sheets combine the neutron absorption ability of boron with the deceleration ability of polyethylene, which can improve the overall shielding effect.”
