The improvement and development of new routine in manufacturing and characterization of materials especially in molecular and atomic scales heighten mankind hope to dig out extraordinary approaches to solve complicated problems in Science and technology. This approach named as Nanoscience and Nanotechnology. Over the last decade, enormous research had been done by many researchers around the world using these techniques.
The novel techniques in Science and technology are such as miracle for research in Nanoscience and technology, it has been said that these techniques not only facilitate the improvement of Nanotechnology but also gave it a magical renewal which everybody knew it in the world.
As you knew natural energy resources such as coal, petroleum, and natural gas take millions of years to form naturally and cannot be replaced as fast as they are consumed. Mankind life standards have been boosted by using cheap energy resources in the last century without caring about environments and renewal of these resources. The next generation will ask us “Why did you run out of all of treasures we had on the earth?”
Although it is not so easy for us to visualize how our life will change when we have no Energy resource to use, But just consider recent increase of oil price which escalated to a worrying level and affected all aspects of people life around the world by increasing of living costs and foodstuff.
There are fears that in long-range forecast because of increasing the consumption and decreasing the available non-renewable resources the energy price rise gradually and became a luxurious material that just prosperous people can afford it. In a simple expression we can expect that the further living standards will decline if we couldn’t utilize new resources and materials.
Renewable energy sources are generally sustainable in the sense that they cannot "run out" as well as in the sense that their environmental and social impacts are generally more benign than those of fossil. Conversion of even a small fraction of the solar radiation incident on the Earth’s surface into electrical power has the potential to satisfy the world’s energy demands without generating environmental damaging side products.
Energy harvesting from sunlight and conversion to electricity or novel Idea of direct producing simple chemicals such as Hydrogen, alongside making high density light weight rechargeable batteries, safe and light weight H2 and natural gas containers, high density fuel cells and smart sensors for conserving precious energy and many other aspects will help us to sustain and improve our quality of life.
Nanotechnology plays an important role in photovoltaic devices and is the first nominee for improving of effectiveness and durability of conventional photovoltaic cells. Performance limiting factors in these devices such as surfaces and interfaces and band gap will be solving by implanting Nanotechnology.
Nanotechnology shows a clear optimistic vision of the future only if instantly start to invest wisely on it, and manipulate it in critical subjects as energy and its related fields. Nanotechnology is the only bright spot of future in our research. Recently considerable amount of researches were done in US, Japan and Europe in different fields such as Chemistry, Physics and Engineering but it is just in the starting point and need for escalating more.
The new era of manipulating Nanotechnology has started and there is no escape of it, let’s join and accelerate this progress if you take care about your next generation in the future.
Heat and light from the sun are obvious, Light from the sun arrives at the top of the earth's atmosphere at a power level of about one kilowatt per square meter. It is this heat and light from a modest star (surface temperature only 5500 degrees C), that all life processes on earth are ultimately driven. Without the sun's constant energy input, our planet would quickly radiate away its latent heat and freeze us and everything else very solid in short order.
