Emerging of Nano Technology: Size of the Small, the High Strength

Nanotechnology is now increasingly rapid development. Nanometer itself means one by one billionth of a meter, so the technology is also related to the creation of small objects. In it joined the physics, engineering, molecular biology, and chemistry.

Albert Einstein himself, as part of his doctoral dissertation, to calculate the size of a sugar molecule from experimental data. The results of each molecule is about one nanometer. Nearly one hundred years later, has become the agenda nanometer many researchers.


But, really not all nano technology had truly nano. There were originally dealing with the structure of micron-size or one per one million meter, a thousandth, and larger than other nano. Nanotechnology in most cases is also not really a technology. However, more research form the basis of various structures with dimensions of one to hundreds of nanometers.

NanotechnologyAnother confusion, a number of nano technology has been used since. For example nano-size carbon black particles have been exploited as an additional placard tires since a hundred years ago. Vaccines are often comprised of one or more protein-dimensional nano-scale can also be included in these technologies.
Nature has a lot to create nanostructures. However, a more stringent definition might as submitted Mihail C. Rocco from the National Science Foundation (NSF) in the United States. According to Mihail in the site Sciam.com , nano-technology has a number of important elements; dimensions between one and 100 nanometers, designed through a process of controlling the chemical and physical, and can be combined to form larger structures.
And, according to the definition of technology that actually exists. For example, combining several layers of material, each layer thickness of less than one nanometer, can produce sensors for disk drives are more sensitive. Since its introduction 1975, these magnetic products have become the growth drivers of the data storage industry.

Increasingly smaller size of electronic chips is also a factor that fosters interest in nano technology. Computer company that has a large laboratory, such as IBM and Hewlett-Packard, incorporating a nano in its activities. As the conventional silicon electronic equipment is not used anymore, maybe ten or 25 years, we can be sure the electronic equipment, nanotechnology will replace it.

Outside of biology and electronics, nano particles are used to improve the quality of products daily. For example a company called Nanophase Technologies has made a particle of zinc oxide for sunscreen products (sunscreen), so the cream is usually white turn transparent.

Dream Technology

U.S. government itself has its own agenda for nano technology. They want to create nano-size material which can reduce the size, weight, and needs a power source from the spacecraft, making environmentally friendly manufacturing processes, and form the basis for biodegradable pesticide.

Each study has its own risks. However, nano technology has its own problems. The desire to make it happen as a rule of science that is often mixed with respectable association of futurists who see the nano as a way to techno-utopian, such as the industrial world without pollution, wealth without limit, even the wish to achieve eternal life.

In 1986 for example, appears the book Engines of Creation by K. Eric Drexler is quite popular. This book describes a number of nano machine that is capable of producing virtually all types of goods, and eliminate the problem of global warming, cure disease and prolong life dramatically.

For the non scientists, the dream of Drexler on nanotechnology is seen as a bridge connecting the world of science and fiction. Scientists who've always wanted to find a solution would also be interested to talk about the product or machine delay aging food grower.

Indirectly, Drexler's work may also be a really interesting man jumped into the scientific world. As a subgenre of science fiction books, Drexler technology works like a Star Trek movie that encourages interest in the teenager will space so that eventually a career in astrophysics or aeronautics.

Among the chemists and scientists are now becoming experts nanotechnology, Drexler prediction has its own curiosity. Because until now not been able to be created nanoscopics machines are for example able to help revive the brain that have been frozen.

Zyvex, a company that is interested in nano technology Drexlerian style, has experienced how difficult it is to create nanometer-sized robot. So, the company is now more satisfied handle larger mikromekanis elements.
Beyond the problem was, the world of nano technology is still struggling to integrate the views. Some research will continue to run whatever it is. IBM will continue to build products such as magnetoresistive regardless of whether the research is nanotechnology or not.

For example, nano concept can be put together, the technology could become the basis for the new industrial revolution. To be successful, the technology does not only need to discard the dream of generating nano robot bodies but also eliminates the excessive rhetoric. More importantly, nano science base must move to identify the type of nano technology that should be realized.

Islam Contribution to Science World

Astronomy The most precise solar calendar, superior to the Julian, is the Jilali, devised under the supervision of Umar Khayyam. The Quran contains many references to astronomy: "And it is He who created the night and the day and the sun and the moon; all [heavenly bodies] in an orbit are swimming." [Noble Quran 21:33] These references, and the injunctions to learn, inspired the early Muslim scholars to study the heavens. They integrated the earlier works of the Indians, Persians and Greeks into a new synthesis. Ptolemy's Almagest (the title as we know it today is actually Arabic) was translated, studied and criticized. Many new stars were discovered, as we see in their Arabic names - Algol, Deneb, Betelgeuse, Rigel, Aldebaran. Astronomical tables were compiled, among them the Toledan tables, which were used by Copernicus, Tycho Brahe and Kepler

Short Descripton About Mesothelioma Diagnosis

How do medical professionals diagnose mesothelioma? If you believe that you may have mesothelioma, a qualified medical professional will use a variety of diagnostic tests and methods to confirm the presence of the disease. The first step that mesothelioma doctors will take in evaluating an asbestos related disease is to obtain a full medical history to determine the level and severity of mesothelioma risk factors and presenting mesothelioma symptoms. This interview will consider among other things, where asbestos exposure occurred, the length of exposure and the amount of asbestos that you were exposed to.

What Causes Asbestos Cancer

Asbestos cancer is referred to as such because development of mesothelioma is conclusively linked to asbestos exposure. Asbestos is a fibrous mineral that was used for centuries in a number of different industrial capacities and asbestos jobsites. While it was quite useful, unfortunately it was also carcinogenic, leading to mostasbestos products being banned in the late 1970's. Pleural mesothelioma is caused by inhaled asbestos fibers which lodge in the pleura and lung wall. Because they are quite durable, they cannot be broken down by chemical means or expelled by other body functions.
