Nanotechnology is basically the manipulation of a matter or several matters on a molecular scale. The theory of the technology has been announced since the 1960s, but major researches and developments started during the 1980s. Its introduction to LED production is bringing quality achievements both in lighting solutions and for displays.
LEDs are the most energy-efficient lighting solution on the market, since LEDs convert the majority of energy into light. Still, about 20% of the light emitted by the diode is lost due the high refractive index of LEDs (a certain percentage of the light is reflected back inside the diode and is not emitted eventually). This rate usually depends on the components of the diode. To get this light otherwise lost within the diode, researchers and recently adopted by manufacturers used nanotechnology and created microscopic holes (roughly 400 times narrower than a human hair) on the surface of the diode, usually hundreds of thousands of holes on a single diode.
Since the introduction of Nano imprint technology to this process creating LEDs with nanotechnology it is cheaper and much faster compared to past solutions The so-called Nano LED is a more powerful and efficient LED solution, with definitely lighter emitted. Also, besides reducing the optical loss, recovered light leads to less heat built up within the diode. This way, LEDs can be packed closer to each other, and also have a generally longer lifespan. Another, additional benefit of Nano-LEDs is their high CRI, and a wider range of colour temperature.
An early application of the technology was not even in lighting solutions but in television displays, where nanotechnology resulted in a new generation of LED TVs. First LED televisions are not real LED solutions, they are actually LCD TVs with LED backlighting from the sides. With nanotechnology, LED TVs are created with a full array of LEDs, behind a panel of microscopic or nano dots letting light through emitted by LEDs. This way light is dispersed more evenly, giving the displayed picture more definition, clarity and smoothness. This technology also allows the display to be thinner: the first TV manufactured with the technology is the LG LEX8, which is only 0.88 cm thin.
Nanotechnology brings new, fascinating results regularly. In the field of lighting, one of the latest news is nano-LEDs grown as wires. This technology was accidentally discovered September 2010, when chemists Babak Nikoobakht and Andrew Herzing experimented with growing nano-wires horizontally. With the increased thickness of the gold catalyst, the nanowires grew a nanowall, which electrons can flow across. Charged with electricity the wires produced light, thus researchers named the phenomenon as nano-LED. This technology will allow adding lighting to microscopic solutions, yet its full scale of potentials is undiscovered.
Similarly interesting achievement of nanotechnology in lighting could be the solutions of Academia Sinica and the National Cheng Kung University in Taiwan, where professors implanted gold nanoparticles into leaves of trees, thus creating a bio-luminescent red light. These bio-LEDs need further development, but the aim is to create trees providing street light along roads. Presumable the trees would also absorb CO2 during the night, which is an additional level of photosynthesis.
Nanotechnology used for creating further lighting solutions is a promising future in the most unconventional forms of lighting. Biological lighting or organic lighting are both key perspectives in eco-friendly illumination, which makes research for lower cost and better performing LEDs crucial. is a company that offers a wide range of low and main voltage, eco-friendly, energy efficient and cool running LED lights, like car lights, LED GU10, LED MR11, LED MR16, G4 LEDs and B22/E27 light bulbs and flexible LED strip lights ideal for homes, offices, shops, boats or caravans.

This article began by noting the recent hype in the electronics market, both positive and negative, that has surrounded nanotechnology and appears to be growing less extreme: today, rosy projections of a “trillion-dollar” nanotechnology based electronics market in 10 years or apocalyptic predictions about a “Faustian bargain” or a “Pandora’s box”[1] are heard less often. However, while the hype may have slowed somewhat, it is still there. Growing public awareness combined with the complex, diverse nature of the technologies that are commonly grouped together under the heading of nanotechnology virtually invites misunderstanding, if not actual misrepresentation. For example, in 2010, a respected journalist wrote a series of stories for AOL News with the title, “The Nanotech Gamble: Bold Science, Big Money, Growing Risks,” that faulted the U.S. government’s performance in identifying and protecting the public against alleged health hazards posed by nanotechnology. One interviewee asked rhetorically, “How long should the public have to wait before the government takes protective action? Must the bodies stack up first?” So stinging was the piece to the National Nanotechnology Initiative (NNI) and the National Nanotechnology Coordination Office (NNCO) that the director of the NNCO felt compelled to issue a formal rebuttal. According to the rebuttal, the author “takes an alarmist perspective,” “uses irrelevant examples,” and fails to balance the risks against the benefits of nanotechnology. As some observers have noted, the debate over the AOL News article (which was still simmering when this report was written) is at best a distraction from the research that needs to be done. Business, academia, the media all have an incentive to attempt to cash in on nanotechnology in the electronics market. Various manufacturers have tacked “nano” onto their products and processes, whether or not they deal in nano-size elements, in an attempt to boost sales. Companies that have nothing to do with nanotechnology have “nano” in their names to make them sound more technologically advanced than the competition. Some academic researchers worry that the nano buzzword is being misused to bring in research dollars for dubious technologies and applications, at the expense of legitimate research. Hype inevitably carries with it the risk of a backlash, because it can create unrealistic expectations for nanotechnology. Then, when expectations are not met, people tend to withdraw or worse turn oppositional. A blog entry on The Bespoke Investment Group’s website observed that: “Back in the ‘good ‘ole days’ of the mid-2000s, investors were riding a bull market wave and looking for ‘the next big thing.’ One of those ‘next big things’ was nanotechnology. Ever since the collapse began in 2007, however, the nanotech craze seems all but forgotten. As a result, legitimate nanotechnology products and applications are hurt along with the rest, as funding and markets dry up. The boom and bust provides a cautionary example of the dangers of hype, but nanotechnology has a more tangible nature because it is a set of technologies. This report takes a realistic look at the nanotechnology field in the electronics market and tries to provide a road map to the technologies and applications that are most likely to be commercialized in the next 5 years.

Nanotechnology is an applied science concerning the manipulation of matter on the molecular and atomic scale levels. Current development is limited to the construction of nano-scale objects for use as materials in other technology. Material created using nanotechnology is often more precise and durable because of the certain attributes of matter at extremely microscopic levels. Studies in modern dentistry have discovered uses for these nano-sized particles for dental fillings and sealants, and could be the lead for the cration of artificial bones and teeth.

The word nano refers to the nanometer, a measurement in the scale of a billionth of a meter. Nanotechnology, or microarchitechture, commonly deals with microscopic structures a hundred nanometers and below. While it is looked forward that man can eventually build working technology such as machines and electronic equipments at this miniscule scale, problems may come up due to the various attributes of physical change as it gets smaller. Simple moving machines at the nanometer scale have been demonstrated and manifested, but man is still far away from assembling molecular sized machines. Nano-particles are being applied in a variety of industry, such as medicine, because of its several properties like the increased resistance to wear and tear, and killing bacteria and harmful agents in microscopic accuracy. However, there are concerns about the unknown consequences to the environment and human health.

Two types of methods exist for working with nanotechnology, each approaching the setbacks from a different angle. Bottom-up approach uses several processes to stimulate structures for self-assembly at the desired scale. Top-down approach constructs a structure at a scale easy to be worked at to, and in turn, creates another structure at a smaller, unreachable scale.

Man has been using nanotechnology for quite a long time without even realizing it. The process of turning iron and coal into steel, vulcanization of rubber and even just the sharpening of a razor all depend on manipulations of nano-particles. Even the most tenured dentist Memphis has is most likely a user of nanotechnology.

State of the art applications being used by any top dentist in Memphis include tooth sealants and fillers that use nano-particles to maintain strength, luster and resistance to wear and tear. Silver nano-particles inhibit the growth of bacteria. Thus, fillers and orthodontics use them naturally to impede bacteria growth in order to prevent tooth decay.

It is hoped by the association of professional and licensed dentist in Memphis that they can be able to utilize nanotechnology to reconstruct the bone that has receded over time after the tooth over it has been extracted, thus making implants an actual option. A hope for the long run is that self-replicating nano-machines could repair and rebuild damaged teeth completely.

Nanotechnology is today omnipresent in our lives. In fact, they are present in those areas of our lives, even without us being aware of it. As the areas of application of this technology are very vast, we would not discuss about them in detail in this article. We would rather stick to the use of this technology in cleaning shower enclosures and providing protective coatings to valuable materials.

Nanotechnology and protective coatings:

Nanotechnology is used as protective coverings in almost all glass surfaces for stretch free cleaning. It also improves the longevity of the material and provides protection from various external elements like wear and tear, dust, dirt, debris, moisture and other hazards. In fact it also helps in getting protection from the onslaught of harmful UV rays. And why just in glass surfaces, nanotechnology also provides preventive coatings in materials like fiber, metal, ceramics, marble, and wood too. This method also provides surface enhancements so as to improve the overall characteristics of the desired materials and objects. As has been mentioned before, the use of this method makes any base material water repellent, graffiti and stain resistant. Also, the entire process of nanotechnology is environment friendly and does not cause any harm to its surrounding.

Nanotechnology and shower enclosures:

Nanotechnology is best used in cleaning shower enclosures. These enclosures are an integral part of all modern bathrooms today. They provide a separate wet area in the bathroom leaving the rest of it dry. Most of these shower enclosures today are made from glass which requires maximal maintenance. This is being used widely today to keep the shower enclosures sparkling clean from inside as well as outside. And this is achieved through the use of protective coating that not only improves and but also protects the surface of your shower enclosures. Nanotechnology makes them water repellent which help in making them resistant to bacteria, stain, electric, scratch, and heavy impact as well as repellant to oil. Use this technology to get shiny glass shower enclosures in homes, as well as in commercial places like hotels etc.

Avail Nanotechnology services online:

The internet is the best place for products related to nanotechnology. In fact, there is a wide spectrum of manufacturers selling shower enclosures and other materials with protective coatings available in the online market to choose from. Choose wisely for great products. Authentic and genuine selections lie only in your hands.

Diamonfusion has become one the world’s leaders in Protective coatings of glass and Shower Enclousers by using Nanotechnology around the world with experienced and well established companies of various market.

Over the past 40 years, giant leaps have been made in the field of nanotechnology. What is nanotech, and what is the future of it?
