Scientists from the Hamburg University of Technology and the University Christian Albrecht (University of Kiel) have created a new easiest material in the world- the airgraphite, which consists of a network of hollow carbon nano-and microtubes. The density of airgraphite is less than 0.2 milligrams per cubic centimeter, so that airgraphite has surpassed all previous easiest materials. Because of this low-density, an airgraphite has a very interesting property- the memory of the original form, so the product from airgraphite can recover its original form after compression in hundreds of times. Also airgraphite is the conductor, which makes it possible to use an airgraphite in a variety of industries.

Revealed the secret of Christ's walking on water- THE VIDEO
Friday, 20 July 2012 11:38
http://hainanwel.com/en/unusual-world/1 ... water.html

Inspired by the biblical story of Christ, walking on water, and Youtube, which are illustrative of walking on stage water, in which starch is added, a physicist at the University of Chicago and Dutch physicist from University of Amsterdam, explained the nature of this phenomenon. According to scientists, if the water add the same weight of starch, water from the normal fluid is transformed into liquid, which becomes the property of a solid at a sufficiently rapid dynamic effects on the surface (see the video). According to scientists, a dynamic impact on the surface of a liquid squeezes out the water, the between the grains of starch, dissolved in the liquid, and the friction between them increases sharply, because of this liquid in place shock behaves as a rigid body. Expected to develop chemicals that will dissolve much faster in the liquid and give it the same properties as starch, which makes it possible to use them for military purposes or in floods in time of peace.

The new super-flexible hydrogel can expand up to 20 times
Thursday, 06 September 2012 11:01

http://hainanwel.com/en/unusual-world/1 ... rogel.html

The well-known scientific magazine Nature reported, that a group of chemists from Harvard University, USA under Zhigang Suo for the first time created a super-flexible hydrogel, which can stretch up to 20 times without losing their mechanical properties and resistance to external mechanical influences. As reported, the new structure of the hydrogel consists of a combination of two polymers with opposite properties. Hydrogel, created at Harvard University, has acquired new and unusual properties due to the fact, that its structure can hold water inside with the replacement of one of the polymer nets this double hydrogel mesh of alginate, which is extracted from the cells of brown algae and is long chain hydrocarbons. Alginate and gave new hydrogel ability to recover its shape after repeated stretching, while the mesh of conventional polymers when stretched often deformed. The new super-flexible hydrogel with unusual properties can be will be used in new areas of science and technology- from medicine to the military industry.

Levitation at room temperature is possible- new technology transforms the graphite into a superconductor
Thursday, 13 September 2012 20:58

http://hainanwel.com/en/unusual-world/1 ... uctor.html

As reported in an article, which was published in the "Advanced Materials", a team of physicists led by Pablo Esquinazi from the University of Leipzig, Germany was able to develop the technology, after the application of which the grain of graphite can exhibit superconducting properties at normal room temperature (25 degrees Celsius). If physicists succeed a sufficient number of such high-temperature superconductor of the graphite- it will cause a revolution in transport, as many have seen the focus from soaring of superconductor above a magnet, but before the opening of Pablo Esquinazi, the trick was only possible in the laboratory at very low temperatures, and now it will be possible at normal temperature on the surface of the Earth. Reportedly, after the special treatment of graphite with water, filtered physics graphite and dried in an oven at 100 degrees Celsius, physicists obtained graphite powder granules, whose surface had superconducting properties, which persisted even at 300 degrees Kelvin (27 degrees Celsius). According to Pablo Esquinazi, the graphite surface begins its superconducting properties due to the presence of molecules water in the crystal lattice of graphite, is a combination of some yet inexplicably strongly reduces the electrical graphite resistance, making it a superconductor. However, while colleagues of Pablo Esquinazi managed to turn in the superconductor only a small portion of graphite, but scientists hope to develop a better technology of transformation of graphite into the superconductor, which would also cause a revolution in electrical engineering and greatly increase of efficiency of power plants, which lose much of their capacity due to the use of conventional conductors, since have not been able to get a conductor at room temperature.

In the Ukraine was invented an edible polyethylene
Tuesday, 18 September 2012 21:03

http://hainanwel.com/en/unusual-world/1 ... ylene.html

Sergei TymchUK, a scientist from Kharkov, UKraine was able to make an edible polyethylene, which by its appearance and mechanical properties are very similar to polyethylene, but edible polyethylene breaks in a month. The main component for the production of edible polyethylene is starch, but not common starch, but a special, where amylose and amylopectin are in the ratio of 60% to 40% respectively. During the experimental study of this edible polyethylene showed, that the shelf life of food in it increased almost in three time. According to Sergei TymchUK-if you put your sandwich in edible polyethylene, it will be able to eat without removing of the edible polyethylene.

http://hainanwel.com/en/unusual-world/2 ... phene.html

In the Nature Communications magazine appeared an article of scientists from Monash University in Clayton, Australia, under the leadership of Dan Li, that the Australian physicists have managed to create an entirely new kind of graphene- a rubber porous graphene, the structure of which is similar to the bark of cork oak. Rubber porous graphene has ultra flexibility and capacity to recover form, combining the properties of rubber and graphene. Back in 2010 the Nobel prize in physics received Konstantin Novoselov and Andre Geim for creation of graphene, which has unique physical and chemical properties. It is on the basis of this discovery, scientists from Monash University and created a rubber porous grapheme, combining of Nobel grapheme in structures, which were like a bark of the cork oak, by freezing mist particles of Nobel graphene in a container with water. According to Dan Li, the freezing of water removed of all the solid particles of suspended Nobel graphene into the space between the growing crystals of water, which led to the formation of the porous structure of the graphene particles, resembling the bark of the cork oak. Certain species of graphene is the strongest material in the world, their strength is 100 times stronger than steel, rubber graphene of researchers from Monash University is able keeping the load of 50,000 times its own mass, in addition, the density of the rubber porous graphene is very low, making it one of the lightest materials known to mankind. Therefore, the use of technology researchers from Monash University will create an ultra lightweight armor with previously unseen qualities and will form the basis for a wide variety of devices, where appropriate unusual strength, electrical conductivity and density- from using in household products to complete implementation of the project of a space elevator, THE VIDEO:

Darkest material in the world Vantablack created in the UK - VIDEO
Tuesday, 15 July 2014 04:00
British company Surrey NanoSystems has developed the black material known to human. This substance absorbs almost all incident light, reflecting only slight 0.035%, which makes it very unusual for the perception of the human eye. Absence, from a practical standpoint, the reflected light causes that the human eye can not see the twists and form of the object, and differ only in its path. If someone is trying to wear clothes made of similar material it would look like a two-dimensional, as if the photograph contour cut on clothes and put it on a black background. The new material has already received the name Vantablack or "super black." It consists of a very thin nanotubes grown on an aluminum substrate with a thickness of 10 thoUSAnd times thinner than a human hair. Even light can not penetrate through the tube so thin, but it passes through the pores around these tubes, where the material and being reflected inside until almost completely absorbed. Another feature of the material is its high thermal conductivity, in excess of seven times the thermal conductivity of copper. Vantablack will be used in science to calibrate telescopes, infrared cameras and space, in particular for taking the oldest objects in the Universe, and it will require more guidance on the black portions of the Cosmos. Besides Vantablack interested and military, but in Surrey NanoSystems can not comment on the area of application in this field, VIDEO:

Nanofilm of a biodegradable polyester PLLA protect from burns- VIDEO

Scientists from the United States have developed a new coating of nanofilms, which can be attached to any part of the body to protect them from disease-causing bacteria in burns. New nanofilm was successfully tested on laboratory mice and demonstrated at the American Chemical Society (ACS). New nanofilms can be applied to any surface of irregular shape without adding glue, so the technology can seriously change the way the treatment of burn victims. At the heart of nanofilms is biodegradable polyester PLLA, in tests in mice nanofilm protected mice against the bacterium Pseudomonas aeruginosa (Pseudomonas aeruginosa), the caUSAtive agent of nosocomial infections in humans, nanofilm protects the wound from infection during the six days, VIDEO:
