What really determines the industrialization of solid-state batteries may not be the energy density of a single material, but the stability and manufacturing consistency of the electrode-electrolyte interface.
The new generation of bioceramics is no longer just a "replacement" but actively participates in tissue regeneration through ion release and microstructure design.
If you were asked to define the different stages of human civilization in one word, what would you say?
Have you ever thought about a question:
If materials could talk, they would laugh at human ignorance.
The screen you are staring at now, although you can't feel its existence, is most likely made of some kind of aluminosilicate.
Don't paddle away in a hurry. I know what you are going to say: "Concrete? Isn't that just cement and water? Is this considered high technology?"
Please go to the kitchen and pick up that flat-bottomed non-stick pan.
Did you watch the fairy tale movie "The Wizard of Oz" when you were a kid?
If materials science has a "character", then titanium (Titanium) is definitely a tsundere.
If you throw an iron rod out in the wild and look at it a few decades later, it will be gone. Only a pile of reddish-brown powder remained, blending into the soil.
If you now travel to 10 million years later, you want to see evidence of the existence of human civilization. By that time, the Great Wall might have weathered into mounds of earth, the skyscrapers would have rusted into slag, and even the radiation from nuclear waste would have faded away.
If you were asked to choose the most "bewitching" one in the periodic table of chemical elements, it would definitely be it.
If you were to select "the greatest inventors of the 20th century", Edison would probably be on the list. But if you choose "the most dangerous creature of the 20th century", Thomas Midgley will definitely be at the top of the list. Even Hitler has to step back a little. After all, Hitler relies on the army to kill people, but Midgley only needs to let you "breathe" to kill people.
Reach out your hands and look at your skin. Touch your muscles again, they are made of protein. The core of protein is amino acid, and the core of amino acid is nitrogen (Nitrogen).
If you were to go back to Hamburg, Germany, in 1669 and walk into the basement of the alchemist Henning Brand, you would be so fumed by the smell that you would pass out on the spot.
Have you ever noticed that there is very little blue in nature? Except for the sky and the sea (that is physical refraction), it is difficult to find blue animals and blue rocks.
If materials science also has a constellation, then Nitrogen must be Gemini, and the most crazy one.
The acid-base reaction is not simply the two liquids canceling each other out, but the result of the recombination of hydrogen ions and hydroxide ions.
Rusting is not the unilateral "oxidation" of iron, but a set of electrochemical processes involving electron transfer, water film and oxygen.
When a white or yellow solid appears after mixing two clear solutions, the ions in the solution are crossing some solubility boundary.
The catalyst is not consumed by the reaction, but can significantly change the reaction speed. The key is to reduce the energy barrier through which the reaction passes.
Behind a plastic fiber, a transparent bottle and a soft film may be long chains of small molecules that are continuously connected.
Changes in the color of the solution often indicate changes in the molecular structure, oxidation state or coordination environment.
The cleaning power of soap comes from the two ends of the molecules: one end likes water, the other end likes oil, and finally the oil is encapsulated in micelles.
The battery does not create electrons out of thin air, but allows oxidation and reduction reactions to occur at two electrodes respectively, and forces the electrons to pass through an external circuit.
Combustion is not just "lighting up when encountering oxygen", but a chemical process in which combustibles are oxidized and energy is concentrated and released.
In a seemingly static equilibrium system, reactions in both forward and reverse directions are still happening at the same time, but at exactly the same rate.
The volume of a gas comes primarily from the space in which the molecules move, rather than the size of the molecules themselves.
The shape of a crystal records how the particles are arranged and also records the history of temperature, concentration and growth rate.
The buffer system can absorb the impact of a small amount of acid or alkali, keeping the pH of the solution relatively stable.
Enzymes are highly selective catalysts in living systems, using their shape and local chemical environment to identify target molecules.
Floral, fruity and baked aromas are not abstract sensations but the result of the interaction of volatile molecules with olfactory receptors.
Bleaching usually does not remove color, but destroys the structures in molecules responsible for absorbing visible light.
Glass is not as neatly arranged as crystals, but it can obtain unique optical and mechanical properties through its amorphous structure.
Photocatalytic materials absorb photons to generate electrons and holes, which can further participate in redox reactions.
