7 Strangest & Coolest Materials Which Actually Exist !

welcome to TTI and welcome to a whole
new world of science today we’re going to explore the seven most unique
materials that you would think would have to be from the world of science
fiction but stay tuned because we’re going to run where the science behind
So my friend sit back relax and enjoy the video number seven ultra hydrophobic
material generally there is some interaction between solid and liquid but
it’s difficult to imagine these unique tiny drops that are unable to wet the
surfaces of material science has made some great progress in recent decades in
the field of hydrophobicity and opening a wide range of application the hydrophobic surface is based on the
Lotus effect this effect was discovered in the 1970s from the microscopic
observations of the natural hydrophobic properties of the surface of a lotus
leaf the Lotus plant is comprised of an adhesive nonpolar and wax-like substance
which is what causes the Lotus effect or hydrophobicity which is featured by the
lotus flower which always appears clean despite growing in muddy areas research in this field is very advanced
and focused on finding a material with the highest level of water repellency to
achieve a material extremely water repellent which would be a huge help for
many industrial fields this is a live demo of a hydrophobic surface it’s water
repellency is investigated by simply insulating it and dipping it in water
the insulated device is protected by water damage which we extremely love for
our smartphones during the rain in addition your walls can be protected
from any dirt after being coated with this magic materials number six triiodide nitrogen triiodide
is one of the chemical compounds which is highly unstable oil it can be
detonated by contact or anybody labels nitrogen triiodide is the molecule
consisting of single nitrogen atom which is bonded by three iodine atoms it’s
structure is similar to a pyramid with nitrogen at the tip and iodine is much
larger than those of nitrogen telling each other you might have heard that
nitroglycerin which is another type of contact explosive can go off when you
hit it with a hammer while iodide with its ammonia should be kept in moist
conditions in a dark place where it is stable but if it’s sufficiently dried at
the right moment it can blow up from just the slightest disturbance this
explosion releases a purple iodine vapor which is irritating and can actually be
toxic with extended exposure in fact on April 1st it earned the
credit for being a highly explosive substance sharing the same core as the
famous nitroglycerin number 5 hydrogel hydrogel is a gel polymer able to absorb
water 30 to 60 times its own volume and it’s able to change its size under the
influence of temperature it’s composed of small white crystals that are able to
absorb a lot of water the total absorbency and swelling
capacity are controlled by the type and degree of cross linkers used to make the
gel thanks to its amazing water absorption capacity it’s used in
greenhouses and agricultural nurseries to retain water and moisture in soil for
a much longer time in recent years the hydrogel has been used as a single plant
substrate this product is also getting attention in the field of decorative
ornamentation indoors the material also is commonly used for
medical purposes for tissue engineering and in sustained-release systems of
medication number four nitinol nitinol is composed of nickel and titanium in
almost equal proportions it has the special ability to rebound to its
original form even after you mold it into different shapes a phenomenon
called the memory effect which is driven by heat exchanges it is able to repeat
this process many times over without losing the ability to regain its
original shape this material has a wide range of applications in the fields of
electronics and mechanics it can also be used in smartphones robotics and medical
industries development and continuation of this material is very expensive but
this problem can be solved by the mass production of the material in the coming
years number three metal gallium gallium metal is one of the least known in the
scientific field this strange metal is very mysterious and difficult to
understand for members of the scientific community gallium is a soft metal which
is a brittle solid at low temperatures and liquid at temperatures greater than
twenty nine point seven six degrees Celsius if you keep it in the palm of
your hand for just a few minutes your body heat will cause the solid metal to
gradually turn to a liquid gallium has the same metallic color in both solid
and liquid forms upon solidification into a mold it becomes just like this
coin this metal is very cool because it’s a non-toxic material but it’s
certainly not cheap one kilogram of this metal cost three thousand dollars which
is an extremely high price that goes showed just how much it must cost to
extract it number two aerogel also known as frozen smoke
aerogel is a broad term used to talk about a special group of materials they
have been used since the early 1960s in space travel but scientists are now
finding multiple uses thanks to its properties the aerogel is the lightest
solid material that exists today its chemical structure is similar to glass
but its density is a thousand times lower and it’s only three times as dense
as air because it contains 99% air ingredients with silica gel despite its
low weight this material is very strong it has heat insulation properties that
have been exploited by NASA engineers to the fullest nasa use this material in
several of its spacecraft to provide heat protection from the sun today the
aerogel is used in the detection of nuclear radiation absorption of
long-lived nuclear waste thermal insulation and detection of harmful
microorganisms number one magnetic Thinking Putty this stuff is pretty cool
to play with this magnetic monster is so amazing and full of fun it can be
created by simply adding ferric iron oxide powder to regular silly putty and
then the putty becomes ferromagnetic only strong magnets that are also
ferromagnetic will be engulfed by this tiny Magnum monster if you place a Ferro
magnet in the magnetic field it will experience a force that pulls into a
region of stronger magnetic strength thank you for watching I hope you liked
it now calmy guys which one of these materials do you find the most amazing
and why let me know in the comments and if you’re new here then feel free to
subscribe I’ll catch you in the next video peace
