Top 10 Mind-Blowing
Scientific Achievements
10. Electricity Conducting Cement
When it comes to good conductors, cement is usually not the first material you’d think
of…until now. Scientists at the University of Alicante have recently developed cement
that has the ability of conducting both heat and electricity efficiently and without compromising
the strength that normal cement provides. While electricity conducting cement may not
seem like a “mind-blowing scientific achievement” it has huge applications for places like airports
and roads to prevent ice or snow build-up. Not only can the cement exist on its own,
it can also be used as a coating on existing cement to give it heat and electric conductivity.
The cement incorporates carbon nanotubes, which help give it the conductivity and strength
it needs. While the material has proved successful in multiple tests, they are continuing to
improve the material’s conductivity and strength.
9. Bose-Einstein Condensate
Satyendra Bose and Albert Einstein first hypothesized Bose-Einstein Condensates in the 1920s. With
drastically improved facilities and techniques scientists have now been able to create and
observe this completely new form of matter. In simple terms, Bose-Einstein Condensates
are to extremely cold temperatures what plasma is to extremely hot temperatures. At these
extreme temperatures, scientists have found that atoms begin to act in very odd ways.
While no scientists have yet to achieve slowing particles down to absolute zero or the point
at which there is no molecular motion, they have been able to generate the slowest and
coldest temperatures in the known universe right here on Earth. It was during one of
these “deep freezes” that particles were slowed to only billionths of a degree above
absolute zero. Using the atom Rubidium, the scientists Cornell and Weiman discovered that
atoms would clump together forming a “super atom”. All of the same properties are retained,
BCEs take condensing to a whole new level by actually existing in the same place. It’s
such an odd behavior that there is no known way of telling the atoms apart from eachother
once they’ve formed the blob.
8. LiquiGlide
Ever had that irritating moment as you attempt to bang out the last bit of ketchup or shampoo
stuck at the bottom of a bottle? Well not anymore thanks to a new non-stick material
developed by researchers at MIT! LiquiGlide, as it’s called, is a nontoxic, nonstick,
and insanely slippery coating that can have wide applications even outside the realm of
condiments. While it’s not the first “superhydrophobic” material ever invented, it is the first non-toxic
material approved by the FDA that is safe to use with food. By simply turning the bottle
upside down, all of its contents smoothly slide out with no residue. Not only can it
save companies money by eliminating the need for creating costly specialty caps and bottles,
it also saves the frustration of banging the last bit of ketchup onto your plate. It works
with both glass and specific kind of plastic. Companies are beginning to quickly take notice
of the amazing material and it should be appearing in bottles very very soon.
7. Deep Voice Gas
We’ve all heard of helium gas that gives people high pitched voices, but have you ever
heard of the gas that can make you sound like Darth Vader? Sulfur Hexafluoride is a man-made
compound with some pretty interesting and unique abilities. Its abilities come from
the fact that it’s an incredibly dense and heavy particle. Not only can you inhale it
and suddenly become Barry White, you can float things on it and make them look like they’re
levitating. Due to its weight, the speed of sound is slowed down considerably when trying
to fight through the gas, causing your voice to deepen. Likewise, sulfur hexafluoride sinks
to the bottom of a container when exposed to the air and has the density to cause things
like tinfoil boats to float on it and look as if they’re floating in mid air. While
sulfur hexafluoride has both fun and practical application, caution has to be taken when
inhaling it because it could sink to the bottom of your lung and remain their if not exhales
properly much like It would outside your body.
6. Upsalite
Imagine making the most absorbent substance known to man…by accident. Researchers at
Uppsala University in Sweden accidentally left equipment running over the weekend causing
the magnesium carbonate they were working with turn into a powder that has a surface
area of 800m for just 1 gram of it. This extremely porous material is so absorbent, it’s referred
to as an “impossible material”. The most expensive absorbent material used now, zeolite,
doesn’t even hold a candle to its absorbency. It has massive implications for things like
humidity control and large scale oil clean ups. The impressive material is surprisingly
easy and inexpensive to make as well. The pores that little Upsalite’s surface are
smaller than 10 nanometers, for those non-scientists a nanometer is on BILLIONTH of a meter. It
goes to show that even little mistakes can end in great successes.
5. Nitinol
When asked to describe the properties of a metal memory and elasticity usually aren’t
the two words that come to mind unless you’ve heard of nitinol. Nitinol is an alloy of nickel
and titanium created in the Naval Ordnance Laboratory by William Buehler and Frederick
Wang in 1958. Its properties exist at two phases, austenite and martensite. At low-temperatures
(martensite) the alloy can be deformed and manipulated, but pops right back into shape
at high-temperatures (austenite). This ability to miraculously pop right back into its parent
shape is known as thermal shape memory. Along with its incredible memory, Nitinol is also
known for its ability to be extremely useful in super springs because of its elasticity.
The superelasticity works hand-in-hand with its thermal shape memory to snap it back into
place. While Nitinol has received criticism for certain medical uses due to its nickel
composition, it is very useful in applications where a lot of flexibility or movement is
involved. While most metals are known to break after continuous bending, Nitinol has been
proven to be nearly immune to breaking under this stress. Since its invention, it has been
used in a variety of industrial and technological applications. The possibilities for this amazing
material are continuing to grow as industries look for materials that can take a hit and
keep on going.
4. Breathing Liquid
While it may seem like an idea right out of a science fiction movie, humans have the ability
to breathe through liquids with the use of Perfluorocarbons. What makes Perfluorocarbons
so special? Well, it’s their amazing capacitance, or ability to hold oxygen particles. While
normal air has a capacitance of 30 times that of water, Perfluorocarbons have about 20 times
the ability of water. Before you go and fill a pool with Perfluorocarbons for no reason
other than to look cool and swim for hours, it does have some pretty cool uses practically
and medically. Diving suits have been filled with it to mimic fish and prevent problems
like nitrogen narcosis. It also have serves as a way to save the lives of premature babies
or help those with respiratory problems. The uses for this amazing scientific invention
are growing with seemingly no end in sight.
3. Self-Cleaning Clothes
No more cleaning clothes? Yep, scientists have finally developed a material to solve
the problem of dirty laundry. Using only sunlight, the special cotton material breaks down not
only dirt and residue, but toxic chemicals as well. A student at UC Davis has done this
by embedding 2-anthraqunone carboxylic acid into cotton fabric by binding it to the cellulose.
It works by breaking down the dirt in the fabric like peroxides do to the bacteria found
in wounds. While the clothes are a bit more expensive, as anyone would expect self-cleaning
clothes to be, researchers say that other chemicals similar to 2-AQC could work just
as well and less expensively. Before you go sell your washing machine, you may not be
seeing self-cleaning clothes on store shelves for quite a while. It’s inventors are looking
towards more practical applications in places like the military or hospitals where clean
closes are more vital and hard to come by than to the average Joe.
2. Oxygen Injection
David Blaine currently holds the world record for holding his breath an amazing 17 minutes,
but thanks to a new oxygen injection, anyone could easily hold their breath for 17 minutes
or longer without discomfort. Thanks to a breakthrough new oxygen particle invented
by the Boston Children’s Hospital, humans can survived up to 30 minutes or more without
taking a breath. What makes this particle so special is the fact that it’s surrounded
by a fatty material, allowing it to be easily injected into the bloodstream. After injection,
blood-oxygen levels can be returned to perfectly normal within just seconds. The particles
are unlike any oxygen particles invented because they don’t cause bubbles (embolisms) upon
injection. The particles deform to prevent this problem from occurring. The applications
of the particle in medical world are endless. This miracle particle has the possibility
of saving millions from those with respiratory failure to those who simply have trouble breathing.
1. Invisibility Cloak
Masking the appearance of someone with an invisibility cloak is one thing, but scientists
have now figured out a way to mask time as well. How does this happen? Well Purdue scientists
have found a way to manipulate the speed of light by speeding up the front of its wavelength
and slowing down the end in optical fibers, so no one can perceive what you’re doing.
It essentially creates a little “hole” in space-time where you can do basically anything
you want without notice. The idea itself was mathematically proven as being possible in
2010 (not including the premiere of Harry Potter) and has since been successfully developed.
While the cloak part itself doesn’t exist, scientists are intending to weave the optical
fibers into a cloak like material. The material will have the ability to hide anything under
it from everyone around you. The whole process occurs in 36 trillionths of a second and scientists
are continuing to develop
the technology.
