7 most exotic materials in the world

People always try to find new materials with more superior features. And among them there are materials that seem to just come out of sci-fi movies .

Here are the 7 most bizarre materials on the planet:

7. Ultra Hydrophobic - Super waterproof material in the modern world

Recent science has made some significant progress in developing super-waterproof compounds and opening up many useful applications in life. Ultra Hydrophobic is one of them. This material is studied based on the water resistance of the lotus leaf.

The lotus leaf effect is an inspiration for scientists to create Ultra Hydrophobic ultra-waterproof materials.

When observing the natural water resistance under a microscope in the 1970s, scientists discovered that in the lotus leaf contains non-polar non-polar wax, so the lotus leaf can "keep I " clean in the swamp.

Ultra Hydrophobic has extremely diverse applications. This material can be used to create waterproof, muddy, and dirty clothes and shoes. In addition, with superior water permeability, it can be used to coat electronic devices to help them function well in water environments. This is also an ideal type of "wall" to protect your home from dust or dirt.

6. Nitrogen Triiodide - Extremely sensitive "chemical compound"

Nitrogen Triiodide is an unstable oil chemical compound that can explode with any sudden contact. Its chemical structure consists of a nitrogen atom at the top linked to three iodine atoms, forming a tower shape.

Nitrogen Triiodide has a pyramidal chemical structure, consisting of one nitrogen atom at the top associated with three iodine atoms.

Some other compounds from nitrogen such as nitroglycerin can explode as soon as there is strong contact force, while Nitrogen Triiodide explodes with only slight touch of a ball, forming toxic and unpleasant purple smoke.

This compound has many useful applications in life but will be disastrous if it is used as a weapon during the war.

5. Hydrogel - High-strength polymer and record elasticity

Hydrogels are a type of polymer that is capable of absorbing water 30-60 times the size of its own size and can change its size under proper temperature. It exists in liquid crystal form. The ability to absorb and increase the size depends on the type and percentage of impurities that produce the gel.

Hydrogel is widely used in medicine to make contact lenses, wound surface coatings, tissue regeneration and cell nuclear replacement.

Currently, Hydrogel is widely used in greenhouses and agricultural nurseries, helping to keep the soil moist and water hundreds of times better than before. In addition, this material has great potential for medical use with tissue transplantation techniques. And this can also become a very unique home decoration item.

4. Nitinol - Flexible alloy capable of remembering

Nitinol is an alloy between Titan and Nickel with an almost equal ratio. It is capable of returning to the original shape no matter how you wrap it, breaking it with its memorization effect. Even though many heat exchangers repeat many times, it is still capable of returning to its original shape.

Nitinol is widely used in the fields of electronics, mechanics, smart phones and medicine. Although this material is quite expensive, this problem can be solved when they are mass produced in the future.

3. Gallium Metal - Metal melts in human hands

Gallium (gallium) , a chemical element with an atomic number of 31. This is a substance that does not exist in nature, but is easily found after the reactions of aluminum, zinc . and extracted from crude oil hydroxide aluminum.

Gallium melted in human hands.

Gallium metal is one of the least known substances. This type of metal is very strange and difficult to understand for scientists. Gallium has an extremely eye-catching appearance, beautiful iridescent with characteristic silver color. It is a soft metal but solidified when cold and liquefied at temperatures greater than 29.76 degrees Celsius.

If you keep a solid gallium metal in your palm for a few minutes, your body temperature will liquefy. This metal is very special, can destroy glass, metal, but is completely human-friendly and non-toxic. However, the price is not cheap, 1 kg gallium costs about 3,000 USD.

Gallium is used in many applications in physics as well as daily activities. LEDs are one of the most typical applications.

2. Aerog - the world's lightest solid material

Aerogel, also known as frozen smoke, is a common term for a special group of materials used for aerospace industry since the early 1960s.

Aerogels are the lightest solid material in the world, with the same chemical structure as glass but their molecular density is more than 1,000 times. It is 3 times heavier than air and 1,000 times lighter than glass.

Aerogel is so light that it can be placed on a flower.

Despite the modest weight, it is very powerful. It can withstand its heavy object 10,000 times. In particular, a well-insulated airgel should be used in the aerospace field to protect astronauts under the sun's heat radiation.

With those extraordinary abilities, Aerogel deserves the name 'the best material on the planet'. Not only used in the aerospace industry, this material is also used to detect the absorption of nuclear radiation by nuclear waste and to detect harmful microorganisms.

However, the production cost of Aerogels is very large, since only a very small amount is produced at a time and production conditions require state-of-the-art equipment. The current price is quite expensive, about $ 100 per cubic centimeter, equivalent to $ 23,000 per pound (about 453.6 g).

1. Magnetic Thinking Putty - Magic clay

This is a special plastic capable of absorbing the magnet's magnetic field and sucking other metal objects. It can rush to a magnet like a living creature and quickly swallow a magnet like a monster in a short time. It is made by removing iron oxide metal powder into clay to turn it into a ferromagnet magnet.

Magic clay can rush to a magnet like a living creature and quickly swallow this magnet.

When there are no nearby magnets, magic clay will be like other clay, you can round, stretch as you like, even tear like tearing paper.

This special toy will make your entertainment hours enjoyable, help you relieve stress, tired after hours of study and work.
