5 Non-conventional uses of nanotechnology
It is difficult to foresee the future without the presence of nanotechnology. The manipulation of matter at the atomic and molecular levels under paved the way for major advances in chemistry, biology and medicine. However, applications that are conducted for nanotechnology are much broader and more diverse than we imagined.
5 - Oil recovery
Global spending for oil exploration has increased exponentially in the last decade. However, the efficiency of oil recovery remains a major problem. When the oil companies close an oil, less than half the oil in the tank is extracted. The rest is left as it is trapped in the rock where it is too expensive to recover. Fortunately, with the help of nanotechnology, scientists in China have discovered a way around this.
The solution improves existing drilling technique. The original technique involves injecting water into the pores of the rock where the oil is. This moves the oil and forces. However, this method shows its limits when the oil is extracted in the pores accessible. By then, the water begins to leave the place and oil.
To avoid this, researchers Chinese Yuan Peng and Li Ming came up with the idea of infusing water with nanoparticles that can clog the passages between the pores of the rock. This method is intended to make water take narrow roads in the pores that contain oil and force the oil. With field studies successfully in China, this method has proven very effective in recovering 50 percent of the black gold that remains otherwise out of reach.
4 - High-resolution displays
The images of computer screens are presented through small dots called pixels. Regardless of their size and shape, the number of pixels on a screen has remained an important factor in image quality. With traditional displays, however, more and more pixels of the displays: a bulky obvious limitation.
While companies were busy selling their huge screens for consumers, scientists at Oxford University have discovered a way to create pixels that are a few hundred nanometers in diameter. This has been achieved by exploiting the properties of a phase change material GST (called a material present in the thermal management of the products). In the experiment, scientists used seven layers GST nanometers thick sandwiched between transparent electrodes. Each layer of only 300 nanometers-300 acts as a pixel can be switched off electrically. By passing an electric current through the layers, scientists were able to produce images with only quality and contrast.
Nano-pixels used for different purposes than conventional pixels become unworkable. For example, the small size and thickness make an excellent choice for technologies such as smart glasses, folding screens, and synthetic retinas. Another advantage of the nano-pixel screens is their low power consumption. Unlike existing displays update all pixels continuously to form images, TPS-layer based screens only update of the display that changes made, saving energy.
3 - Change paint color
Experimenting in chains of gold nanoparticles, University of California scientists have encountered a surprising observation. Realize that the color of the bag of gold when its particles chain stretches or shrinks, producing what one scientist described as a bright blue beautiful it becomes purple and red were given. The finding has inspired scientists to create gold nanoparticle sensors that change color when pressure is applied.
To produce the sensors, the gold nanoparticles are to be added to a film of flexible polymer. When the film is pressed, it expands and causes the particles to separate and color change. Lightly press violet sensor while pressing harder makes red. Scientists have observed that not only interesting property of the gold particles and silver particles that become yellow when stretched.
The sensors can be used for various purposes. For example, they could be integrated into furniture such as sofas or beds to assess seating positions or sleep. Despite being gold, the sensor is small enough to overcome the problem of cost.
2 - Load Cell
Whether an iPhone, Samsung, or different kind of phone every smartphone that comes shipped with two notable disadvantages: the life of the battery and the time it takes to recharge. While the former is always a universal problem, scientists of the city of Ramat Gan in Israel have not addressed the second problem by creating a battery that requires only 30 seconds to reload.
Progress has been awarded to a project related to Alzheimer's disease, which was conducted by researchers at the University of Tel Aviv. The researchers found that the peptide molecules that shorten the neurons of the brain and cause the disease have a very high capacity (the ability to maintain electrical loads). This has contributed to the founding of StoreDot, a company that focuses on nanotechnology consumer products are targeted. With the help of researchers, nanodots Store Dot developed that exploits the properties of the peptides to improve the battery life of smartphones technology. The company has demonstrated a prototype battery if Think Next Microsoft. The use of a battery of Samsung Galaxy S3 was accused of zero to full in less than a minute.
1 - Sophisticated Drug Delivery
Treatments for diseases such as cancer and can be prohibitive in some cases, too late. Fortunately, several medical companies around the world looking for effective ways to treat diseases and good market. Among them is Immusoft, a company that aims to revolutionize the way drugs are delivered to our bodies.
Instead of spending billions of dollars on medications and therapy programs, Immusoft think we can design our body to produce drugs for themselves. With the help of the immune system cells of a patient can be modified to receive the new genetic information that allows them to make their own medicine. Genetic information can be delivered as capsules nanoscale is injected into the body.
The new method has not yet been tested in a human patient. However, Immusoft and other institutions have reported successful experiments in mice. If proven effective in humans, the method significantly reduce the cost of processing and treatment of cardiovascular disease and other diseases.
