An unusual connector
(10) | 09/07/2014 | Translate: The British research analyst Andy Elliott us demonstrates the unique qualities of a fastener that is manufactured from alloy nitinolis (nickel-titanium). The "magic trick" by nitinoli is based on temperature change, which makes it a very useful material in the field of medicine.
A frozen fish comes back to life Experiment with a fish that has been frozen and thrown into a basin of water. After a few minutes, the fish thaws and returns to life. Many Arctic fish, Antarctica and the North have evolved to adapt to such conditions. Some types of cod, flounder and other polar fish have a reduced metabolic rate and can produce specific hormones with antifreeze properties. These hormones are called glycoproteins and reduce the freezing point of fluids in the body., which allows them to be kept at low temperatures for a short time.- Restoration of a stadium seat The thermoplastic from which the seats of a stadium are made, is a type of polymer that can be liquefied and formed very easily with temperature. Polymers are not very hospitable in sunlight, from which they are destroyed and weakened, which is why the seats blur and lose their color under sunlight. Thus a thermoplastic polymer can be restored to its original appearance by heating, as color is present in the structure of the material.
- A fireproof super-material that you can make in the kitchen by Ben, He shows us how he managed to create a highly refractory material that can withstand high temperatures. His inspiration was the Starlite, a material invented in the 1980s by Maurice Ward, but no one ever learned the recipe posthumously.
- induction iron A knife is immediately heated to incandescent temperature, using induction. The induction Fusion is an application of Faraday's law, where heat is transferred to a conductive material through a magnetic field without the presence of physical contact. The changing magnetic flux passing through the conductive material causes the current flow in this, which is responsible for the heating of.
- The new windscreen wiper system of Mercedes The new windscreen wiper system of Magic called Vision Control Mercedes, It works according to the outside temperature and automatically adjusts the wash liquid quantity with the surrounding circumstances. The company has released this video to introduce the new system. It would also be useful to give us some information on the prices of spare parts.
- The Launcher thermite The British craftsman Colin Furze, He constructed a makeshift weapon triggers and launches containers with thermite, a material that can melt even metal. You can see here the process of construction.
- Quantum buoyancy The superconductivity is a condition of certain materials that have the ability to conduct electricity with no resistance. This property disappears over a temperature or under a magnetic field and is a quantum state. Here a superconducting material that has very low temperature since it contains liquid nitrogen on the surface, presents this quantum state and has the ability to hover over magnets, without friction.
- Gallium Gallium is a fusible metal that liquefies slightly above room temperature and melts easily in hand. Also an interesting capacity is that can decompose the molecular structure of aluminum very quickly and to destroy. Therefore the international air transport association ranked the gallium in corrosive materials, and prohibits all passengers to carry with them when they travel by plane Gallium.
- Induction melting The induction Fusion is an application of Faraday's law, where heat is transferred to a conductive material through a magnetic field without the presence of physical contact. The changing magnetic flux passing through the conductive material causes the current flow in this, which is responsible for the heating of. Here a piece of aluminum is heated inductively, with temperature reaches 1200 degrees Celsius.
- 3d Printing 3D printing is a production technology, where a three dimensional object is created by using special printers or chasing a material in layers, or stereopoioyn a special powder in the form of the object. 3D printers give manufacturers the ability to create useful accessories, moulds and prototypes.
- Piranha: a very useful tool Who would have thought that a piranha would serve as a cutter;
- The moment TV channels switched to color image Snapshots from the moment TV channels changed their image from black and white to color. Each channel celebrated the event in its own way. In order, there is Norway in 1972, the United States in 1958, Germany in 1967, Australia in 1975 and France in 1967.
- Ice city ride The Harbin Ice and Snow Sculpture Festival is an annual event held in the city of Harbin, China since 1963. Harbin, it is the capital of Heilongjiang province and has a very cold climate in winter. The average temperature in January is -16,8 °C but can reach as low as -38,1 °C often. So, the population has developed a culture closely associated with snow and ice. The festival starts on January 5th and lasts for at least a month. The ice sculptures contain the traditional themes of Chinese folklore, such as traffic lights, up to more modern scenes that incorporate lasers. They are located in various parks in the city where guided tours are organized.
- Claws aren't always useful A woman's dramatic effort, desperately struggling to pick up her bank card that has fallen to the ground, with her long nails.
- The hydrophobic properties of duck feathers The video shows the hydrophobic properties of the feathers of the Iceland mallard. Eiderdown is the down left behind by wild ducks after the natural process of moulting, and no ducks are captured for this process. Eiderdown is one of the lightest, softest and warmest materials in the world, and is extremely rare.
