Pang Xuelin knew that Du Jiaxiang and his grandfather still had something to discuss, so he followed Xiao Gao around the laboratory.

Xiao Gao is a doctoral student under Du Jiaxiang, and when Pang Xuelin talked to the boss about the use of the laboratory just now, he heard it clearly, and he was envious and admired for this fifteen-year-old boy.

What I envy is that Pang Xuelin is so young that he has been valued by his boss.

Du Jiaxiang is a bigwig in the field of carbon nanomaterials, and he can get his favor, and his future in the domestic academic circle is limitless.

What I admire is that Pang Xuelin really persuaded his boss to lend him the laboratory for use.

Xiao Gao knows Du Jiaxiang's character, he is not smiling, taciturn, and does things one by one, and he doesn't know how to be flexible.

Such a person, unless you really have real skills, you can't get into his eyes at all.

Pang Xuelin was able to win Du Jiaxiang's favor, which can only show that he is really good in the professional field.

As for jealousy, the little high-pressure root will not have it.

He heard the conversation between Pang Xuelin and Du Jiaxiang clearly just now, this is likely to be the second boss of the future laboratory, the big boss said a word, and the experimental dogs under his hands may have to work for him.

It's too late for such a character to stammer, how can he be offended!

Du Jiaxiang is the State Key Laboratory of Chemical Engineering of Jiangxi University, and the equipment and research facilities in the laboratory are of the first-class level.

"Xiao Pang, this is our high-performance liquid chromatograph, which is used to analyze the composition and concentration of compounds with high boiling point, strong polarity, poor thermal stability and large molecular weight."

"This is a nanoparticle size and zeta potential analyzer, which can measure the zeta potential, particle size and particle size distribution of emulsions, microemulsions, and nanoparticle dispersion systems; Zeta potential can be measured at different pH values to find the isoelectric point. It is suitable for the study of particle characteristics and emulsion stability of polymer emulsions, inorganic nanoparticle dispersion systems, drugs and other particles. ”

"This is a field emission scanning electron microscope (SEM), which is used to observe the secondary electron image and backscattered electron image of the surface morphology of various solid-state samples, and a high-performance X-ray spectrometer equipped with a large window SDD probe, and at the same time qualitative, semi-quantitative and quantitative analysis of micro-point, line and surface elements on the surface of the sample, with the ability to comprehensively analyze morphology and chemical composition. Compared with the general tungsten filament scanning electron microscope, it can observe the surface microstructure and morphology of solid samples with higher resolution, and analyze the surface ultrastructure and morphology of metals, inorganic non-metals, polymers, nanometers and other materials. ”

"This is a high-speed countercurrent chromatograph for separating and preparing samples from micrograms to grams; Extraction of active ingredients from crude samples or biological fluids; A small amount of chemical components is concentrated from a large amount of aqueous solution, which can be widely used in the analysis and separation of complex substances such as metal ions, natural substances, and biomolecules. ”

"This is a fully automated physicochemical/chemical adsorption analyzer for the determination of the specific surface area, pore volume, pore size distribution, and dispersion of metals (or their oxides) of solids; It can measure various solid, inorganic or organic substances, and the sample pore size should be below 100nm. ”

"This is a scanning probe microscope (SPM), which acquires image data from micrometer to atomic scale (such as roughness, particle size, height, etc.) with atomic-level resolution, real-time, real-space, in-situ imaging. It is widely used in nanotechnology, materials science, physics, chemistry and other fields. Temperature-controlled samples are heated and cooled for biological, polymeric materials, and other materials research applications, and can be scanned in liquid environments of water, solution, or buffers.

……

Xiao Gao introduced the important instruments and equipment in the laboratory to Pang Xuelin one by one, and at this time, Pang Xuelin came to a workbench and suddenly stopped.

On the table was a cylindrical metal cylinder the thickness of an arm, and on the wall directly in front of the workbench was a drawing of an airbag with two feet pinned to it.

Pang Xuelin couldn't help but be stunned, isn't this thing just the life-saving air bag invented by the protagonist in the movie?

"This is yours?"

Pang Xuelin wondered.

Xiao Gao scratched his head and said a little embarrassed: "This is a life-saving airbag made of graphene materials, and I also applied for a patent and found a company to produce it, but I didn't sell a few at all." Professor Du said that I don't do my job, and I do everything I can't do. ”

"How many credits is this, can you sell me a few?"

Pang Xuelin's eyes lit up, this thing is an artifact, in the movie, it is with this kind of airbag that the protagonist has survived many crises.

Xiao Gao said: "How much do you want, I'll give it to you, this thing can't be sold after it is produced, and I have hundreds of them at home!" ”

As he spoke, Xiao Gao squatted down and pulled out a box from under the workbench, which was full of this kind of life-saving air bag.

Xiao Gao was just about to take out the life-saving air bags one by one, but Pang Xuelin only felt that the house shook suddenly.

Immediately afterwards, the ceiling lamp and the water in the water storage tank shook violently.

"It's an earthquake, get here and take shelter!"

Pang Xuelin was still in a daze, and Xiao Gao dragged Pang Xuelin into the space under the workbench.

After about ten seconds, the vibration gradually dissipated, and Xiao Gao breathed a sigh of relief and said, "Okay! ”

Pang Xuelin followed Xiao Gao out of his hiding place, his face turned slightly pale, and asked, "Is this an earthquake?" ”

He had never experienced an earthquake before, and it was the first time he had experienced the feeling that the whole building was shaking.

This made him very uneasy.

Xiao Gao nodded and said, "Yes, the intensity is not high, it should be a small-scale earthquake to release the stress inside the earth's crust." The mass of the planetary engine is too large, which puts pressure on the entire continental plate, and the global seismic activity has been much more intense in recent years, but our Jiangcheng is okay, only two or three small earthquakes come every year, and in some places it is possible to have more than a dozen times a year. The last time magma seeped into the Berlin dungeon, it was the product of a major earthquake. ”

Pang Xuelin nodded, his heart tightened slightly, this period of peaceful life almost made him forget what kind of era this was.

In his impression, there has almost never been an earthquake disaster in Jiangcheng, and now even this place has an earthquake, so is the super tsunami that flooded the whole of Shanghai in the movie caused by an earthquake?

Pang Xuelin's heart lifted slightly.

"Brother Gao, can this life-saving air bag give me a few more, no, I want to give it away!"

"Okay, I'll fill it for you!"

Xiao Gao stuffed more than a dozen life-saving air bags in Pang Xuelin's backpack before he could do it.

Pang Xuelin is going to give it to his grandparents and his parents who are far away in Shanghai, keep two for himself, and give the rest to Yao Bingxia, so that she can also send a few to her relatives.
