Chapter 316: I want to do one big thing

Fiction Net, the latest chapter of the black technology system of Xueba will be updated as soon as possible!
Across North America, samples sent from the Salotte Laboratory in Silicon Valley were finally sent to the Frick Chemistry Laboratory.
After signing the package, Lu Zhou took the samples to the rented laboratory.
Recently, he learned that, in addition to applying for the school's scientific research fund, Flick Chemical Laboratory not only provides paid third-party testing services, but also rents the laboratory for a fee and purchases the hours of equipment.
The fees for third-party testing services are generally more expensive, often tens of thousands or even hundreds of thousands of dollars, but if you rent equipment for experiments, the price is within an acceptable range.
After completing the procedures for leasing the instrument, Lu Zhou and Professor Chirick made a phone call and borrowed a PhD student as an assistant.
Like last time, this time it was Connie.
This doctor with the same size as a rugby player is much stronger than when he saw it last year.
Looking at Connie with a smile, Lu Zhou's expression was strange.
"Did you switch to research biology?"
"No," Connie paused slightly. "Why do you ask?"
"Nothing ..." Lu Zhou shook his head. "Forget it, when I said nothing."
I always feel that if his physique continues to expand, there is great potential to develop into Hulk Hulk.
But it's too hurting to say that.
"... Actually, I know what you want to say," Connie sighed, and scratched his head in distress. "Just because I am too big, Professor Chirick always keeps me from touching those experimental instruments and worrying about me. Spoil those things. "
"It's too ..." Looking at the depressed Conney, Lu Zhou didn't know how to comfort him. "In short, I won't do this to you."
In terms of size, Professor Crich is not small. He is at least a small forward on the basketball court.
Wiping his nose, Connie moved: "Really? What do you need me to do?"
Lu Zhou gave a subtle glance at the scanning electron microscope in the eye laboratory, and finally he couldn't rest assured: "In short ... you want to help me process the sample, you should be able to."
Connie grinned. "Cover me!"
After taking out more than thirty samples sealed in small glass jars, Lu Zhou ordered Connie to take some precautions, and carefully took out a small amount of black powder from the glass jar marked with sample No. 1, and Mix with ion water and shake well.
Before shipping, Salotte has processed the samples. In addition to containing a small amount of impurities that cannot be filtered, these powders have reached laboratory purity and no further filtering is required.
However, it is definitely impossible to stuff the sample into the observation. The agglomeration of the hollow carbon spheres will make the observation worse.
With the help of Connie, Lu Zhou tirelessly performed ultrasonic dispersion processing on each sample, and then carefully took samples with a plastic dropper, and in turn dropped all the sample test solutions on the copper sheet.
"Get it!"
Finally, all the samples were processed, and Lu Zhou, who took a breath, put down the last piece of copper, stretched a lazy waist, and moved a stiff neck.
Since the carbon material itself is a conductive material, it is relatively simple to handle, and this step is considered complete. If it is an insulator material, the sample must also be gold treated.
Does it sound expensive?
Actually not expensive.
Compared to other precious metals and organic reagents consumed in the laboratory, gold is a relatively cheap consumable. For example, the average cost per milligram of these samples sent by Saloette is more than $ 100.
Therefore, Lu Zhou has reason to be so careful. After all, he spends his own money on experiments.
Fortunately, Connie, who was an assistant on the side, did not fail his hopes, and a sample was not messed up. Putting down the last piece of copper, Connie looked at Lu Zhou and asked.
"I'm OK here too. What shall we do next?"
Lu Zhou thought about it and said, "Sweep it with a scanning electron microscope first."
The rest of the work is very simple. Lu Zhou operated the instrument step by step, glued the copper sheet carrying the sample to the conductive tape on the sample holder, and then sent it into the sample chamber.
After confirming that the vacuum pressure in the sample chamber was kept at a stable value, Lu Zhou spoke to himself while skillfully inputting various parameters.
"The emission current is set at 10μA, the working distance is 8mm, and the scanning mode is Sei ..."
With two joysticks on the sample controller, Lu Zhou carefully moved the position of the sample stage. Connie, who was standing in front of the computer, adjusted the diaphragm and acceleration voltage according to his requirements.
With that done, everything is ready.
Finally, it was time to harvest the fruits of victory.
This process is much easier and more pleasant than the previous complicated and complicated operations.
Through the computer to adjust the control resolution, adjust the acceleration voltage and working distance, switch the detector, Lu Zhou can easily collect any data he wants.
Looking at the instruments at work, Connie, operating the computer, couldn't help feeling.
"This thing is so much better than a normal electron microscope."
"That's a must," Lu Zhou said with a smile. "If the experiment goes well, I can give it to you when there aren't enough machines left."
Connie exclaimed, "Really? Thank you so much!"
Although his boss also has a scanning electron microscope that can be used, UU reading www.uukanshu.com, but it is clear that Professor Chirick will not waste time on his students' doctoral dissertation. After all, there are too many students for him.
At this moment, the land boat standing in front of him is almost like an angel, oh no, God.
Lu Zhou smiled and said not much, "Of course it is true. As long as you do what I say, I will definitely not let you work for nothing."
With the promise of Lu Zhou, Connie obviously became more motivated.
As the resolution is gradually enlarged, the microstructure of the hollow carbon sphere is presented in front of the two without reservation at the nm scale.
Looking at the scanned pictures, Lu Zhou suddenly moved in his heart.
He thought of something, and said immediately.
"Connie, help me screen out these samples for hollow carbon nanospheres with a specific surface area in the [2326m2g-1, 3762m2g-1] range and a diameter in the [60nm-70nm] range!"
"Okay," without any hesitation, Connie immediately started operating the computer. After comparing the data, he quickly reported, "... Report Professor, samples Nos. 11, 14, 15, and 23 all meet your requirements. Any instructions? "
The corresponding glass jar was removed from the sample price, and Lu Zhou stared at the black powder in the glass jar with his back to Connie.
"I need you to do one thing now."
Connie seriously said, "Just tell me."
"Let me borrow a battery tester and a button battery mold," Lu Zhou continued, "and some samples of elemental sulfur.") Book friends pay attention!
