  • Scientific Achievements

  • 10. Electricity Conducting Cement

  • When it comes to good conductors, cement is usually not the first material you’d think

  • ofuntil 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 achievementit 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

  • thesedeep freezesthat 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 theyve 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 firstsuperhydrophobicmaterial 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

  • Weve 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 theyre

  • 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 theyre 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 manby 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 animpossible 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 youve 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 youre doing.

  • It essentially creates a littleholein 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.
