The Last Alchemist

For an exploratory scientific experiment, failure is expected, and success is a low-probability event.

Rosen was mentally prepared, so he didn't feel discouraged.

He rested for a while, then immersed himself in thinking, carefully sensing the solution in the medicine bottle.

'Before, I controlled the natural diffusion of the mandrake poison, and the various molecules were only changed in relative position, which was just a simple physical change. But this time, I need to convert one molecule into another, which is a chemical change. The difficulty is incomparable, and it is far beyond my ability. What should I do? "

The physical process of molecules diffusing in liquids only needs to overcome the intermolecular force, whose strength is between a few tenths and tens of kilojoules per mole (gaseous state, standard atmospheric pressure). Chemical changes, however, require breaking the chemical bonds in the molecules, and the strength of chemical bonds is usually around hundreds of kilojoules per mole.

The former is at least one order of magnitude higher than the latter, and the difficulty is greatly increased.

"What should I do? "Rosen lowered his head and stared at the liquid in the bottle.

The solution in the bottle, from the outside, looks no different from clear water, but in his perception, these liquids are not as calm as they seem on the surface. In the solution, various auras surge and collide with each other without rules, seemingly never stopping, just like a pot of boiling soup.

A thought suddenly came to Rosen's mind.

'Molecules move all the time, and the macroscopic manifestation is the temperature of the object. The higher the temperature, the more violent the molecular movement, and the more intense the collision between them. When the temperature reaches a certain critical point, the intensity of the molecular collision can even destroy the molecular structure and cause chemical changes.'

At this moment, as if in response to Rosen's thoughts,

several coincidences appeared in the aqueous solution, and an extremely The subtle breath was suddenly hit by continuous collisions of the surrounding breaths. What's more, these collisions were in the same direction. As a result, the breath suddenly increased by hundreds of times and began to rush through the solution.

'Well~ This is a high-energy particle with a small probability. If this force is stronger, it will be enough to destroy the chemical bonds. Wait, I have a way! '

This method is simple and crude, and has a wide range of applications. That is the collision method!

Chemical bonds are very strong, and Rosen's alchemical power cannot break them directly. This is a fact, but if he uses the alchemical power to accelerate the nitrate ions in the solution, control their direction of travel, and turn them into shells to bombard the hydroxyl groups in glycerol, he may achieve his goal.

The best thing is that in aqueous solution, nitrate ions are free. To control them, you only need to overcome the intermolecular forces, and this is exactly what Rosen is capable of.

Rosen's eyes sparkled, and his brain began to work at high speed: 'I have the main idea, but how to implement it specifically. I have to study it carefully. '

The strength and angle of the bombardment are very particular, and it is a delicate job.

The best result is that the nitrate ion can just knock the hydroxyl out, and after the collision, its own energy is just exhausted. In this way, the nitrate can just replace the position of the hydroxyl and will not fly away again.

It sounds simple, but it will be very difficult to do.

Why?

Because of quantum effects.

At the size of molecules and atoms, quantum effects are very obvious. In this field, the uncertainty principle will Start to show off your power. In the quantum world, there is no certainty, only probability. Everything is possible. The only difference is the size of the probability.

Because of this, the real chemical change process is extremely complex, and there are countless specific changes.

Anyone who wants to control the chemical change process must first have a direct understanding of chemistry.

In this world, other alchemists cannot have this knowledge. They don’t even have the concept of atoms and molecules, let alone quantum mechanics that dominate the microscopic field.

But Rosen from Earth is different. He just has the relevant knowledge.

At this time, Annie saw that his eyes were straight and thought he was stupid. She couldn’t help but comfort him: "Rosen, don’t worry. If you can’t think of a way for the time being, we can continue to set bait."

Rosen looked up at Annie blankly and suddenly asked: "Annie, do you know the nature of chemical bonds?"

"Ah? What is a chemical bond?" Annie was confused by the question.

Rosen’s eyes began to shine: "The essence of chemical bonds is electromagnetic action!"

"Ah? "Annie opened her rosy lips, totally unaware of what Rosen was talking about.

Rosen ignored her, he was completely immersed in his own world of thought, his eyes sparkling with wisdom: "Any chemical change is the breaking and reorganization of chemical bonds. And the essence of chemical bonds is actually the dance between electrons and photons. In this field, there is a god-like quantum theory, that is quantum electrodynamics! '

"Quantum electrodynamics. What is electrodynamics?" Anne was going crazy, she could understand every word Rosen said, but when they were put together, she didn't understand it at all.

'Is this a term in alchemy? But I have also learned some alchemy, how come I have never heard of these words? 'Annie's brain was almost a paste.

Rosen still ignored Anne's doubts, he was completely immersed in his own world, and a mysterious smile appeared on his face: "Yes, it is quantum electrodynamics!"

Quantum electrodynamics, the most mature branch of quantum field theory, mainly studies the basic process of interaction between electromagnetic fields and charged particles.

Quantum electrodynamics is almost perfect in its applicable field, and the field it can explain is very, very broad. In this world, all natural phenomena outside the realm of relativity and the interior of atomic nuclei can be described with it.

As for chemistry, it is just a part of it.

It can be said that quantum electrodynamics is one of the most powerful thinking weapons that Rosen currently possesses. It can even be called an artifact!

With this thinking artifact, Rosen can even call himself the God of Chemistry!

The method has been thought of and the artifact is in place, so what are you waiting for?

Rosen immediately got to work.

He entered a 'trance' state again, his mind completely immersed in the solution in the bottle, and his whole body remained motionless, as if he were an inanimate wood sculpture.

Anne was completely disorganized.

After being stunned for a long time, she came back to her senses and continued to rub the silver balls.

After about ten minutes, she felt that the silver beads in her hands became smoother and smoother.

"strangeness."

Anne couldn't help but spread her hands to look, and found that every silver bead on her palm had become round and round, and the surface was very shiny. It felt very smooth and very beautiful to the touch.

‘It’s so beautiful. ’ Anne almost couldn’t put it down.

She thought this was very strange. She turned to look at Rosen and saw that he was sitting there with his eyes closed. If it weren't for the beads of sweat on his forehead, she almost thought he was asleep.

'This little guy is a weirdo. People are weird, their thoughts are weird, and what they say is even weirder. ’ Anne secretly thought.

However, she also knew that Rosen was a very smart man and an alchemist, so she tried to remain silent afterwards so as not to disturb him. Anyway, she had nothing to do, so she followed Rosen's method, hydrated the dough with salt water, wrapped the rabbit meat, and baked the rabbit meat white dough on the campfire.

About 30 minutes later, Rosen took a long breath, opened his eyes, and woke up.

Annie had been paying attention to Rosen and immediately asked, "Okay?"

"Yes." Rosen's face was pale, but his eyes were as bright as stars, with a satisfied smile on his face.

He used an extremely ingenious method to convert saltpeter and glycerin into two other substances. One was potassium hydroxide, commonly known as caustic potassium, which is highly alkaline.

The other product sank to the bottom of the medicine bottle. It was a translucent, light yellow oily liquid that resembled thick nasal mucus. The amount was not large, less than 15 ml.

In order to get this thing, Rosen almost risked his life.

This light yellow oily liquid is the nitroglycerin that made the chemist Nobel the famous explosives king!

This chapter is a bit obscure and has been revised many times. This version is currently the simplest. From now on, Lao Mo will explain as little as possible. In addition, Lao Mo wanted to say that everything is physics, and chemistry has almost become a branch of physics. It belongs to the small branch of 'molecular physics'.
