Scholar’s Advanced Technological System

Across the whole of North America, the sample sent from the Sarrot Lab in Silicon Valley was sent to the Frick Chemistry Laboratory.

After signing the parcel, Lu Zhou took the sample to the rented lab.

Recently, he learned that in addition to applying for the school’s research fund, Frick chemistry lab not only provides paid third-party testing services, the lab can be rented for a fee, and the instrument’s machine time is also available for purchase.

The fees for third-party testing services are generally more expensive, tens of thousands or even hundreds of hundred dollars, but if you rent an instrument to do the experiment, the price is within an acceptable range.

After completing the procedure for renting the instrument, Lu Zhou and Chiric Professor called and borrowed a doctoral student as an assistant.

Like last time, this time is the same Connie.

This doctoral figure, like the rugby player, is much more sturdy than when he saw it last year.

Looking at Connie with a smile, Lu Zhou’s expression is a bit odd.

“Are you studying research biology?”

“No,” Connie snorted. “Why are you asking?”

“Nothing…” Lu Zhou shook his head. “Forgot, when I said nothing.”

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

But when this is said, it is too hurtful.

“…I actually know what you want to say,” Connie sighed, scratching his head with some distress. “Because I am too big, Chiric Professor always keeps me from touching the experimental instruments, worried that I will put those Something is bad.”

“That’s too…” Looking at Connie, who was depressed, Lu Zhou didn’t know how to comfort him. “In short, I won’t be like this to you.”

To say the block, the Crich Professor is not too small, and at least a small forward position on the basketball field.

With the nose wiped, Connie was moved: “Really? What do you need me to do?”

Lu Zhou had a subtle look at the SEM in the lab, and I couldn’t help it: “In short… you want to help me with the sample, you should.”

Connie grinned and said: “Package on me!”

After taking out more than thirty samples sealed in small glass jars, Lu Zhou gave Connie a few things to be aware of, and carefully removed a small amount of black powder from the glass jar labeled No.1. Mix well with ionized water.

Before the shipment, Sarrot had already processed the sample. In addition to containing a small amount of impurities that could not be filtered, these powders had reached laboratory purity and no further filtration was required.

However, it is definitely not possible to insert the sample into it. The agglomeration of the hollow carbon sphere itself will make the observation effect worse.

With the help of Connie, Lu Zhou took the trouble to ultrasonically disperse each sample, and then carefully sampled with a plastic dropper, and successively dropped all the sample tests on the copper.

“Get it!”

Finally, after processing all the samples, Lu Zhou took a sigh of relief and put down the last piece of copper, stretched out and moved some stiff neck.

Since the carbon material itself is a conductive material, it is still simple to handle, and this step is completed. If it is an insulator material, the sample must be steamed.

Does it sound expensive?

In fact, it is not expensive.

At least gold is a relatively inexpensive consumable compared to other precious metals and organic reagents consumed in the laboratory. For the samples sent by Sarrot, the average cost per milligram is more than one hundred dollars.

So Lu Zhou is so cautious that there is a reason. After all, he spends his own money on experimentation.

Fortunately, Connie, who was an assistant at the side, did not live up to his hopes, and a sample did not mess up. Putting down the last piece of copper, Connie looked towards Lu Zhou.

“I am also OK here, what are we doing next?”

After thinking about it, Lu Zhou said: “First scan it with a scanning electron microscope.”

The rest of the work was simple. Lu Zhou stepped on the instrument, glued the sample-loaded copper to the conductive tape on the sample holder, and then sent it all into the sample room.

It was confirmed that the vacuum pressure in the sample room was kept at a stable value, and Lu Zhou spoke to himself and entered the parameters skillfully.

“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 station, and Connie stood in front of the computer, adjusting the aperture and accelerating voltage according to his requirements.

After completing this step, all the work is ready.

Finally, it is time to harvest the fruits of victory.

This process is much more enjoyable than the complicated and complicated operation in the front.

By adjusting the resolution of the computer, adjusting the accelerating voltage and working distance, and switching the detector, Lu Zhou can easily collect any data he wants.

Looking at the instruments at work, Connie, who operated the computer, couldn’t help feeling.

“This stuff is much easier to use than a normal electron microscope.”

“That’s a must,” Lu Zhou laughed said. “If the experiment goes well, I can give it to you when you have a lot of unused machines.”

Connie is excitedly said: “Really? Thank you so much!”

Although his Boss can also be used with SEM, it is clear that Chiric Professor will not waste his time on his student’s Ph.D. After all, his student is too much, and it’s too fast to manage.

At this moment, Lu Zhou standing in front of him is like Angel, oh no, God.

Lu Zhou laughed, I didn’t care too much. “Of course it is true. As long as you do what I said, I will definitely not let you work.”

After receiving the promise of Lu Zhou, Connie apparently became more energetic.

As the resolution is gradually enlarged, at the nm scale, the microstructure of the hollow carbon sphere is presented unreservedly in front of the two.

Looking at the photos that were scanned out, Lu Zhou suddenly felt a move.

He thought of something, and immediately said.

“Okay,” Without any hesitation, Connie immediately began to operate the computer. After comparing the data, he quickly reported that “…Reports, 11, 14, 15, 23 samples are all in line with your requirements. Is there any more? What is the indication?”

The corresponding glass jar was removed from the sample price, and Lu Zhou stared at the black powder in the glass jar, back to Connie.

“I need you to do one thing now.”

Connie said seriously: “You are told.”

“Help me borrow a battery tester and a button-type battery mold,” looked around the lab, Lu Zhou continued, “and some samples of elemental sulfur.”

“I want to do a major event.”
