Conserve Energy with Nanotechnology Solar Panel
Posted by Nadya in nanotechnology on April 22nd, 2010
With the evident effects of environmental neglect, energy all over the world is becoming more and more depleted. With energy sources becoming scarce, it generally results to a stiff competition to obtain the limited sources for energy resulting to high power charges. There are several sources of energy, and some of them are even natural resources such as wind, solar, and hydro. But even if the sources of energy are natural resources and should be delivered to the people at a lower cost, still, power costs are high due to expenses incurred while generating electricity.
For several years now, scientists and researches has been looking at other means to obtain the following:
- minimize generation costs of energy
- provide energy to the people without causing any damages to the environment
- generate renewable and recyclable energy resources
- provide energy and electricity with the least possible charges
- deliver electricity and energy to the public at the lowest possible cost
Achieving These Goals Using Nanotechnology Solar Panel
Nanotechnology aims to build important things with the use of tiny machines or by producing highly advanced, essential, and quality products using tools and techniques provided by nanotechnology.
Part of the researches being conducted is to come up with a solar panel that would accurately capture solar energy that can be utilized at home, in the office, and even in large-scale industrial areas. Although there are already solar panels available in the market today, these solar panels that are usually made of silicone panels only capture 67.4% light incident or solar energy emitted by the sun. Whereas, with nanotechnology, industrial and electrical manufacturers can now produce a coating for solar panels using nanorods that can capture 96.7 % light incident.
Nanorods used in nanotechnology solar panel looks like multi-layer funnels designed to capture light incident. The first layer absorbs the light that hits the panel at wide outer angles and turns it to a slightly narrower angle. The succeeding layers become narrower, like they are passing the light to the next layer even further as it funnels the light till it reaches the active region of the panel at a 90° angle. This process makes the solar panel securely capture the sun’s energy without having to rotate with the sun.
Benefits of Nanotechnology Solar Panel
Installing a nanorod on your solar panel can give out a lot of benefits not just for your personal advantages but to the whole of mankind. Some of these benefits include:
- Lower solar power cost. The usual silicone solar panels available in the market today are placed at a single angle and can therefore absorb and generate lesser energy making the cost of solar power high. Nanotechnology solar power is designed to absorb the sunlight from any angle thus making generating more energy and making it available at a lesser cost.
- Environment friendly. By patronizing renewable sources of energy such as energy coming from the sun, you would help in saving the world in your own little way. Solar power is also proven safe and does not emit hazardous waste.

Nanotechnology in Pharmaceutic Manufacturing
Posted by Nadya in nanotechnology on April 22nd, 2010
Imagine producing essential products such as medicines, fabric, glass, steel, and plastic materials for your home and office in almost in a blink of an eye. Or think about treating chronic and serious health conditions such as cancer, lupus, or even HIV thru a tiny device that can travel inside the human body and destroy the infected cells before they spread and cause debilitating damages to the body. You picture this: a tiny device, even smaller than an atom but can store massive information such as all the information contained in an international library. If you think that is quite impossible, then you probably haven’t heard about nanotechnology yet.
What Is Nanotechnology?
Nanotechnology used to be regarded in the fields of science as a science fiction: impossible and unattainable. But over time, nanotechnology and its uses among different facets of the society such as agriculture, home improvement, industrial, even in areas of environmental protection is already widely accepted and practiced. Nanotechnology in pharmaceutic manufacturing is also being done in big pharmaceutical and health companies. But what is nanotechnology? For people who are not in the fields of sciences and engineering, nanotechnology may be an unfamiliar word.
Nanotechnology is the engineering of functional systems at the molecular scale or thru tiny engineering. In essence, nanotechnology is the probability to build things from the bottom up using scientific techniques and tools that are currently developed today to come up with advanced, complete, and highly usable and essential products.
What Are the Benefits of Nanotechnology?
The basic benefit of nanotechnology is its ability to produce important products in a massive scale with the least or minimum cost. If managed properly, meaning, if the makers of products using nanotechnology would only make products that will provide benefit to mankind with utmost safety precautions in mind, nanotechnology is the next wave of industrial revolution. Nanotechnology will eliminate production costs for materials, labor, and energy because it can produce bigger and better things invented by our forefathers at a staggering speed and amazing precision there is no room for mistakes.
How Can Nanotechnology Be Applied to Pharmaceutic Manufacturing?
Man is exposed to varied health hazards these days due to the advent of science and technology that most often emit hazardous free radicals and pollutants that contribute to the general decline of mankind. Because of this and also because of man’s increasingly sedentary lifestyle, people need more medication for varied diseases. Millions of people are in need of medication and medical maintenance that is why pharmaceutical companies is a booming business.
If nanotechnology in pharmaceutic manufacturing would be applied, with the speedy production of quality medicines at a very minimal cost, it will cause economic and social ripples that could be beneficial to mankind. Because of very low production cost, manufacturing companies would be compelled to lower down the prices of medicines. Nanotechnology in pharmaceutic manufacturing would be beneficial not just to end consumers of the medicines but also to the pharmaceutical companies or drug makers because they would be able to produce quality and highly marketable drugs with the least capital and generation cost needed.

Nanotechnology in Cars: Drive of the Future
Posted by Nadya in nanotechnology on April 20th, 2010
Cars are common expressions of how developed a nation is. True to this statement, the most developed nations of the world have their own and stable car manufacturing industries that they export to the rest of the world, earning revenues for the source country. More than that, some nations have become synonymous with the brand and quality of their manufactured cars as the case of Japan, Germany, and the United States. Unsatisfied with this and all the modifications they have created on their cars, they have taken automotive technology a bit further by using nanotechnology for cars.
When nanotechnology was discovered, the automotive industry was not seen as a possible beneficiary from this piece of knowledge. Yet in time, the automotive industry became one of the heaviest users of nanotech. With nanotechnology in cars, vehicles were made more efficient.
The Application of Nanotechnology in Cars
The following are some of the most common examples of the application of nanotechnology in cars:
- Engine and transmission systems. In contemporary cars, a large share of the vehicle’s weight is due to the weight of the engine and the transmission system of the vehicle. As a result, cars are fuel-hungry because of the need to push forward such a heavy machine. Nonetheless, with the advent of alloys, engines were made lighter somewhat but not sufficient to make them fuel-efficient. The answer came with the arrival of nanotechnology. With nanotechnology, engines and parts were made a lot lighter, thus eliminating the need to consume more fuel just to power the vehicle forward.
- Chassis. In the same manner that the engine and its parts were made lighter, the same benefit happened in the case of the chassis. Aside from being lighter, chassis and engines were also made more durable, making them withstand daily workload on the road.
- One of the most advanced examples of nanotechnology in cars involves the production of paint that is constituted in microvolumes. The idea is to create a surface that automatically heals itself whenever it is scratched or tainted with some foreign mark. This procedure allows for the paint to release nano paint particles that automatically spreads to cover up the scratched area. It works instantly you’ll hardy notice the surface was scratched at some point.
- Another of the advanced applications of nanotechnology for cars involves the production of mirrors and side panels that are made out of nano particles. Being so, they filter the rays of the sun, smoke, and other pollutants in the atmosphere. The same technology allows radio and phone signals as well as sound waves to freely enter the cars so that the occupants of the vehicle will not be made oblivious to the world outside. This is beneficial for those who have some form of hearing defects; even with all the windows closed, you may still be able to hear the honking of the horn of the next car. Likewise, you do not have to open the window when it is raining just to get a clear signal when calling from your mobile phone.

Safety Concerns with Nanotechnology: Knowing the Risks and Benefits
Posted by Nadya in nanotechnology on April 20th, 2010
Nanotechnology is one of the hottest scientific discoveries of the present times. This is because nanotechnology presents a lot of promise that all other treatment methodologies before it were unable to deliver. Moreover, nanotechnology also saw applications in other areas aside from the fields it was intended for. As a result, the fields of applications of nanotechnology are as varied as the possible risks that come with it. As such, safety concerns with nanotechnology aired by ordinary citizens and experts alike must not be ignored because it is one of the ways to make the technology very safe for anyone using them.
Common Concerns with Nanotechnology
The following are some of the most common concerns expressed by people on the use of nanotechnology:
- Nanotechnology is a new scientific application. Although this can also mean to be a benefit for mankind, there are safety concerns related to its applications mainly because of the fact that it is something that is not yet fully tested. One of the safety concerns with nanotechnology in this field involves the application of the technology in medical and health fields. Some are afraid that they might trigger harmful effects instead of the intended beneficial effects.
- Because nanotechnology involves the manipulation of matter at the atomic and molecular levels, there are fears that such manipulation may result to the production of materials that will radically alter man’s way of life. This is seen especially to be dangerous in the field of medical applications where nano particles are used in various ways such as sunscreen and injectable medications. Safety concerns with nanotechnology in these areas are heightened because such manipulation of matter may trigger the body to react in a negative way to the presence of nanotechnology products.
- There are also fears that the environment may be placed in jeopardy that nanotechnology products may increase the pollution level in many areas at a time when the need for environmental conservation is vigorously pursued everywhere. For example, the production of better engines for automotives and windows for cars may prompt car manufacturers and local dealers to wantonly discard these parts that can possibly cause environmental nightmare with the absence of better programs on waste disposal. An interesting twist here is nanotechnology is a thriving business in the United States, amounting to billions of dollars. However, despite all these income, very little thought is spared for health and environmental concerns. Because nano particles are very small, they are very difficult to degrade and may easily pass on from one person to another, in the process becoming agents of ailments.
- Another of the numerous safety concerns with nanotechnology is the lack of a centralized monitoring agency that will see to it that all endeavors in this field are religiously monitored. As a proof of this, there are very little journals and researches on the safety concerns with nanotechnology that inevitably enhances the fears that people may have on this technological applications and advancements.
Regulating Nanotech with Nanotechnology Ethics
Posted by Nadya in nanotechnology on April 20th, 2010
The promises that nanotechnology brings to mankind is so huge that there are some sectors who fear that if its applications are not properly regulated, it can bring harm to mankind instead of the good it is projected to give everyone. As a result, calls for the setting of regulatory procedures in its applications are supported not only by scientists and the industry that benefits from it but also from various groups representing ordinary people. As such, nanotechnology ethics has come to be seen as something as important as nanotechnology itself. In doing so, the scientific community is only reacting to experiences with epoch-setting technologies in the past. Knowing the possible horrors that can affect mankind, nanotechnology ethics are in place for every disciple of the learning to observe.
Defining the Limits of Nanotechnology
Because the full impact of nanotechnology has not been fully realized, various governments and scientists are afraid that the unrestricted applications of nanotechnology will result to health and environmental problems. Characteristic of something that is not fully regulated in a uniform manner, various nations have their own reactions to nanotechnology applications. For example, some aspects of nanotechnology are allowed in the United States with a wide range of freedom—including its use for sunscreen products—but in other countries, the situation is different. In the United Kingdom, nanotechnology ethics also puts into consideration the impact on the environment first, particularly on the release of nano particles to the atmosphere that may trigger pollution. On the other hand, in other countries, the debate on nanotechnology ethics is more on the definition of the size of matter that can be considered as part of nanotechnology.
In large countries such as the United States, nanotechnology ethics are also imposed by individual states, aside from the laws enacted on the national level. In California, for example, nanotechnology ethics are geared towards protecting the environment especially on the disposal of nanotech products to the environment. Such regulation also covers the importation and selling of such products.
One of the hottest debates concerning nanotechnology is on the most promising benefit it holds for mankind: that on the fields of tissue engineering and on the cure for HIV virus. Although both ends are seen to be greatly beneficial for the good of man, both are so touchy and covers a lot of implications that even with the prospected benefits, those who apply nanotechnology in these areas are being very cautious about them. This is because there are some groups and governments who are opposed to any form of medical treatment that has not been proven to be really effective in giving the projected benefit, especially if the procedure involves some risk on the matter of a person’s health. A case in point here is the possibility of nanotechnology being disguised as medically beneficial when it can be used to terminate life or induce abortion and other methods that some groups are essentially opposed to. All said, these opposition to nanotechnology are contributory to the slow pace of the development of nanotech, although on the brighter side of things, it is seen as a way to be certain about the real effects of this unique technology.

Nanotechnology Research: Extending Man’s Horizon
Posted by Nadya in nanotechnology on April 20th, 2010
There is hardly any doubt that nanotechnology is very beneficial to man. With all the applications this new frontier of knowledge has seen from the human body to industries and chemicals, thus far, nanotechnology has lived up to its name in enhancing the wealth of knowledge possessed by man.
Despite this gains however, nanotechnology research continues on high gear to discover more truths that will help man in so many ways. Today, nanotechnology research is not only limited to the laboratories of scientific bodies, personnel under the employ of big companies that benefit from nanotechnology are also doing their own nanotechnology researches.
Frontiers of Nanotechnology Application
The following are the various areas where some of the most prominent nanotechnology research are being undertaken:
- The field of heavy equipment and industries are some of the busiest areas of nanotechnology research. With the projected benefits nanotechnology promises these industries, there is no wonder why they should busy themselves with furthering the impact of nanotechnology. The main benefit comes in the form of creating machineries that are light yet very durable. When equipments are made lighter, they do not cause much strain on the engine, thus it maximizes the consumption of fuel.
- The aerospace and aircraft production industries are also bound to benefit from continuing nanotechnology research. This is because with nanotech, aircraft and rocket parts are made lighter, thus minimizing fuel consumption. As a result, companies that are in the air travel business are also benefited from lower fuel consumption from aircrafts that are lighter and speedier.
- In the field of optical technology, nanotechnology research is used to develop lenses and glasses that are scratch-resistant and tough. It also results to the creation of lenses that do not cause interference with one’s vision, thus giving the wearer clarity of sight sans any inconvenience.
- In the field of cosmetics, one important research on nanotechnology leads to the development of sunscreen based on nano particles. As a result, sunscreens are better when it comes to providing protection from the sun compared to the traditional UV protection systems that is the standard today in most sunscreen products. With nanotechnology-based sunscreens, the cosmetic is able to penetrate deeper into the skin layers to cause the cells to react against getting burned by the sun. This is considered to be far better than simply superficial sun blockage, which is common in conventional sunscreen cosmetics.
- In health, nanotechnology research is also key to advancing tissue engineering. This is very important when there is a need to repair damaged tissues, especially those affected by severe diseases. Moreover, nanotechnology is also one of the most promising applications that scientists are employing in the fight against the human immunodeficiency virus (HIV). In this, the process aims at killing affected cells to prevent their replication and thus stop the spread of the disease. Moreover, because it is atomic in nature, nanotechnology is far better than taking medications because unlike the latter, it does not affect otherwise healthy tissues, specifically attacking only the affected ones.
