Time in Huairou reading
It is one of the most beautiful experiences of xiaobian's academic career
In Yanqi Lake, I met the beautiful campus and the clear starry sky
And the uninvited guests in the dormitory
- Hemp Bug (Bed Bug)
Hemp skin bugs
This insect has stink glands
It can secrete substances such as nonenal and decanoal
Will spray self-protection when threatened
It's indescribable and enduring
Left an unforgettable memory for the editor...
However, the hemp skin bug is compared to the one below
That's really a little witch to see a big witch
Acute toxicity, high temperature burning
Biocatalysis, targeted attack...
These enemy defense mechanisms are all housekeeping skills of the fart infantry
It is a class of insects in the genus Ass in the family Buaceae
In order to resist the attack of ants and other creatures
They spray hot venom against enemies
And their housekeeping skills all depend on
Hydrogen peroxide and catalase in the body
Arsenal of ass armor
Glands of the ass can secrete hydrogen peroxide and hydroquinone
and store in a storage room
Hydrogen peroxide and hydroquinone enter the reaction chamber
It reacts with catalase
where hydrogen peroxide is under the action of catalase
Produces a lot of oxygen
On the one hand, oxidizes hydroquinone for
Benzoquinone with toxicity and irritation
On the other hand, it also acts as a booster
Spray the liquid out of the body
The attack range of the fart cloth armor is 360° and there is no dead angle
Due to the large amount of heat released by the reaction process
The liquid can be heated to about 100 °C
It's a skill that is full of physical and spell attacks
Hydrogen peroxide in the body of the fart cloth nail is a kind
Non-toxic and non-polluting green oxidant
Its decomposition products are water and oxygen
So it's not just insects
Humans also use hydrogen peroxide as a booster for aircraft
Back in World War II
Germany adopts "t-stoff"
(80% hydrogen peroxide and 20% aqueous phosphate solution)
It is used as a propellant in military fields such as torpedoes
The thrust of the V-2 rocket is 10 times higher than that of other rocket engines before it
V-2 rocket engine
Hydrogen peroxide can also be used for chemical synthesis
When reducing the hydrogen peroxide concentration to about 3%.
It is a commonly used medical disinfectant
At the same time hydrogen peroxide acts as an oxidant
Stubborn contaminants and microorganisms can also be removed
It is used in processes such as silicon wafers, separation membrane cleaning as well as destaining and laundry bleaching
Hydrogen peroxide cleaning separation membrane modules
At present, hydrogen peroxide mainly relies on anthraquinone or
Direct synthesis using hydrogen and oxygen
However, the preparation process is complex and the energy consumption is high
At the same time, hydrogen peroxide is unstable, which has potential safety hazards in the storage and transportation process
Anthraquinone hydrogen peroxide production process
It is expected by electrochemical synthesis or photocatalysis
Hydrogen peroxide is produced in situ
Where electrochemical synthesis can be done separately
Redox hydrogen and oxygen and produce hydrogen peroxide
And in the photocatalytic process
Photocatalysts in the valence band
An electron is excited into the conduction band by absorbing photons
This allows the valence band to retain a positive charge
Form electron hole pairs
and further by redox reaction
Hydrogen peroxide is produced
Maybe in the near future
Hydrogen peroxide can
Realize green and clean industrial production
Electrocatalytic, photocatalytic hydrogen peroxide production mechanism
Can clean, can go to heaven, but also put a hand "good fart"
Such hydrogen peroxide
Do you love?
