Nanotechnology

he manufacturing or engineering of functional systems at molecular level or nanoscale can be termed as nanotechnology. The word ‘nano’ has been coined to mean 10-9 or simply one billionth size. Special types of microscopes, scanning probe microscopes, are able to view particles the size of a nanometer.  In another definition, nanotechnology is the engineering of machines from molecules the size of a few nanometers.  These machines can be motors, robots and computers taking up the size...

Flotation

Flotation (formerly referred to as froth flotation) is a common method which is used for separating hydrophobic materials from hydrophilic ones. It is a highly versatile method which is used for physically separating particulate mixtures based on their inherent properties. One major property exploited by this technique is the difference in the ability of air bubbles to selectively adhere to specific material or mineral surfaces in a mineral/water slurry.    Flotation is a process...

Technology and Writing: Impacts and Changes

From decades ago, it is rather proper to assume that act of writing merely required instruments such as pens, typewriters, and of course various forms of parchments on which to write on. However, as technological advancements brought forth and allowed for the use of computers throughout homes and business establishments for making various tasks, such as writing, simpler and easier, it may also be assumed that such tasks were in fact changed in certain ways. To further expound upon the impacts of...

Dangerous and Natural

Earthquakes 1. The west coast of the United States has the greatest frequency of earthquakes, especially California.  The western states of the United States have more earthquake activity than the eastern states.  The least amount of activity occurs in the middle of the continent. 2. My home is Ohio.  Color is predominantly dark grey indicating that risk is at low end of scale. 3. Most of the earthquakes are occurring along plate boundaries. The Pacific Ring of Fire is clearly...
