1. NANOTECHNOLOGY: AN OVERVIEW Nanotechnology is the manipulation of matter on the nanoscale. A nanometer is a very small measure of length-it is one billionth of a meter‚ a length so small that only three or four atoms lined up in a row would be a nanometer. So‚ nanotechnology involves designing and building materials and devices where the basic structure of the material or device is specified on the scale of one or a few nanometers. Ultimately‚ nanotechnology will mean materials and devices

Exploration; to travel in a little-known region for discovery‚ as defined by Webster. Since the age of the Greeks‚ Anglo-Saxons have been interested in space exploration. From Copernicus to Gaileo to Newton‚ space has been looked upon with adoring eyes. Space has been regarded time after time as the final frontier. That was until 1957‚ with the launch of the Sputnik-1‚ when the Soviet built satellite became the first man-made satellite successfully launched out into outer space. In 1958‚ the United

A fuel cell is a device that transfers the chemical energy from a fuel into electricity through a chemical reaction of positively charged hydrogen ions with oxygen or another oxidizing agent [1]. Fuel cells can produce electricity continuously until these inputs are supplied. The first fuel cells were invented in 1838. Since then‚ fuel cells have been used in many other applications. Fuel cells are used for primary and backup power for industrial‚ commercial and residential buildings and in inaccessible

the free encyclopedia http://en.wikipedia.org/wiki/Kaingin Slash-and-burn is an agricultural technique which involves cutting and burning of forests or woodlands to create fields. It is subsistence agriculture that typically uses little technology or other tools. It is typically part of shifting cultivation agriculture‚ and of transhumance livestock herding.[1] Older English terms for slash-and-burn include assarting‚ swidden‚ and fire-fallow cultivation. Today the term "slash-and-burn" is mainly

About Nanotechnology Email | Print Imagine being able to observe the motion of a red blood cell as it moves through your vein‚ or being able to watch as a type of white blood cell (called a "T-cell") destroys an invading microbe by engulfing it. What would it be like to observe the vibration of molecules as the temperature rises in a pan of water? To observe sodium and chlorine atoms as they get close enough to actually transfer electrons and form a salt crystal? New scientific tools‚ developed

Effects Of Genetic Engineering On Agriculture The Effects of Genetic Engineering on Agriculture Agribiotechnology is the study of making altered agricultural products. Agribusiness is trying to alter the genes of already existing products to try to enhance the biocompetitiveness and adaptability of crops by enhancing plant resistance to drought‚ salinity‚ disease‚ pests and herbicides. They are going to try to enhance their growth‚ productivity‚ nutrient value‚ and chemical composition. The old

say that space exploration should be abolished because it is a waste of money‚ but think of how much we have advanced in our knowledge of space. This has to be known because some of the planets and moons we have discovered are suitable for us to live on when we move from Earth‚ so it is essential that man knows about space and we constantly have to keep updating and developing our knowledge. "I don’t think the human race will survive the next thousand years‚ unless we spread into space. There are

Imagine you wake up‚ another day‚ just as always‚ you get out of the bed‚ look at the blue-sky through your window‚ take a deep breath of fresh air and feel the sun warming your skin. Suddenly you hear some air planes‚ flying at a medium height... And by the time you realize that there have been some fungi-shaped explosions with kilometers of diameter around your location‚ you hear something falling near you‚ something big‚ something you know will be the last thing you will hear… Now let me change
