Chapter 317 I Want to Do Something Big

Spanning the entire North America, the samples sent from the Sarot Laboratory in Silicon Valley were finally sent to the Frick Chemical Laboratory.

After signing for the package, Lu Zhou brought the samples to the rented laboratory.

Only recently did he learn that in addition to applying for the school's scientific research fund, the Flick Chemical Laboratory not only provides paid third-party testing services, but also rents the laboratory for a fee, and can also purchase the time of the instrument.

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 an instrument for experiments, the price is within an acceptable range.

After completing the procedures for leasing the instrument, Lu Zhou called Professor Chiric and borrowed a doctoral student from him as an assistant.

Like last time, it was Connie who came this time.

This doctor, who was as big as a rugby player, was much stronger than when he saw him last year.

Looking at Connie with a smile on his face, Lu Zhou had a weird expression.

"Have you changed your career to study biology?"

"No," Connie was slightly taken aback, "Why do you ask that?"

"Nothing..." Lu Zhou shook his head, "Forget it, pretend I didn't say anything."

I always feel that if his physique continues to expand, he has the potential to develop into Hulk.

But it hurts too much to say that.

"...Actually, I know what you want to say," Connie sighed and scratched his head in distress, "It's because I'm too big, and Professor Chiric always doesn't let me touch those experimental instruments, worrying about me Break those things."

"It's too..." Looking at Connie who was depressed, Lu Zhou didn't know how to comfort him, "Anyway, I won't treat you like this."

In terms of size, Professor Creech is not small, at least he can play the position of a small forward on the basketball court.

Wiping his nose, Connie was moved: "Really? What do you need me to do?"

Lu Zhou glanced at the scanning electron microscope in the laboratory subtly, but finally couldn't let go of his mind: "In short...you want to help me process the sample, you should be able to."

Connie grinned: "Leave it on me!"

Taking out more than 30 samples sealed in small glass jars, after Lu Zhou instructed Connie to pay attention to some matters, he carefully took out a small amount of black powder from the glass jar marked with sample No. Mix with ionized water and shake well.

Sarot had processed the samples before sending them, and except for a small amount of unfilterable impurities, the powders had reached laboratory purity and no further filtration was required.

However, just stuffing the sample in for observation is definitely not acceptable. The agglomeration phenomenon of the hollow carbon sphere itself will make the observation effect worse.

With Connie's assistance, Lu Zhou took the trouble to ultrasonically disperse each sample, and then carefully took samples with a rubber dropper, and dripped all the sample liquids on the copper sheet in turn.

"Done!"

After finally processing all the samples, Lu Zhou heaved a sigh of relief and put down the last piece of copper, stretched his waist, and moved his 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 has to be vaporized gold.

Does that sound expensive?

In fact, it is not too expensive.

Gold is a relatively cheap consumable, at least compared to other precious metals and organic reagents consumed in laboratories. Take these samples sent by Sarot as an example, the average cost per milligram is more than one hundred dollars.

So there is a reason for Lu Zhou to be so careful. After all, he spent his own money on the experiments.

Fortunately, Connie, who was on the sidelines as an assistant, lived up to his hopes and did not mess up a single sample. Putting down the last piece of copper, Connie looked at Lu Zhou and asked.

"My side is OK, what shall we do next?"

After thinking for a while, Lu Zhou said, "Let's scan it with a scanning electron microscope first."

The rest of the work was very simple. Lu Zhou operated the instrument step by step, stuck the copper sheet carrying the sample on the conductive tape of the sample holder, and then sent the whole thing into the sample chamber.

Confirming that the vacuum pressure in the sample chamber remained at a stable value, Lu Zhou skillfully entered various parameters while talking to himself.

"The emission current is set at 10μA, the working distance is 8mm, and the scanning mode is Sei..."

Through the two joysticks on the sample controller, Lu Zhou carefully moved the position of the sample stage, while Connie, standing in front of the computer, adjusted the aperture and acceleration voltage according to his requirements.

Once this step is done, all the work is in place.

Finally, it's time to reap the fruits of victory.

Compared with the previous tedious and complicated operations, this process is much easier and more enjoyable.

Through the computer to adjust the control resolution, adjust the acceleration voltage and working distance, and switch the detectors, Lu Zhou can easily collect any data he wants.

Looking at the instruments at work, Connie, who was operating the computer, couldn't help but sigh with emotion.

"This thing is much easier to use than ordinary electron microscopes."

"That's a must," Lu Zhou said with a smile, "If the experiment goes well, I can give you the unused time."

Connie said excitedly: "Really? Thank you so much!"

Although his boss also has a scanning electron microscope to use, it is clear that Professor Chiric will not waste the machine time on his students' doctoral thesis. After all, he had too many students, so many that he could hardly handle it.

At this moment, Lu Zhou standing in front of him is like an angel, oh no, like a god.

Lu Zhou smiled and said indifferently: "Of course it is true. As long as you do what I say, I will definitely not let you work for nothing."

After getting Lu Zhou's promise, Connie obviously became more motivated.

With the gradual enlargement of the resolution, the microstructure of hollow carbon spheres was unreservedly presented in front of the two at the nm scale.

Looking at the scanned pictures one by one, Lu Zhou's heart suddenly moved.

He remembered something, and immediately spoke.

"Connie, help me to screen out the hollow carbon nanospheres with a specific surface area in the [2326m2g-1, 3762m2g-1] range and a diameter in the [60nm-70nm] range from these samples!"

"Okay." Without any hesitation, Connie immediately started to operate the computer. After comparing the data, he quickly reported, "...Professor, samples 11, 14, 15, and 23 all meet your requirements. Any instructions?"

After removing the corresponding glass jar from the sample price, Lu Zhou stared at the black powder in the glass jar and said with his back to Connie.

"I need you to do something right now."

Connie said seriously: "You just give orders."

"Borrow me a battery tester and a set of button battery molds," Lu Zhou continued, looking around the laboratory, "and some samples of elemental sulfur."

"I'm going to do something big."
