Welcome to the nano scale. Nanoscale is where properties differ significantly from those at a larger scale. The strange world of nanoscience can take you into atoms and beyond the stars. A new horizon has begun for mankind in creating new technologies and one day eradicating diseases. That water bottle that turns urine into drink water could help drought stricken countries, instead of a little water bottle maybe a water tank version? Introduction to Nanoscience What is nanoscience? The word itself is a combination of nano, from the Greek "nanos" (or Latin "nanus"), meaning "Dwarf", and the word "Science." Nano refers to the 10-9 power, or one billionth. In these terms it refers to a meter, or a nanometer, which is on the scale of atomic diameters. For comparison, a human hair is about 100000 nanometers thick! Nanoscience is the study of atoms, molecules, and objects whose size is on the nanometer scale ( 1 - 100 nanometers ). Why is the study of nanoscience different than the same problems on a larger scale? Physics is different on the nanometer scale. Properties not seen on a macroscopic scale now become important- such as quantum mechanical and thermodynamic properties. Rather than working with bulk materials, one works with individual atoms and molecules. By learning about an individual molecule's properties, we can put them together in very well-defined ways to produce new materials with new and amazing characteristics. Why is nanoscience suddenly becoming such a big ...
Dr. Wade Adams is the Director of the Smalley Institute for Nanoscale Science and Technology at Rice University. The Institute is devoted to the development of new innovations on the nanometer scale. Some of the institute's current thrusts include research in carbon nanotubes, medical applications of nanoparticles, nanoporous membranes, molecular computing, and nanoshell diagnostic and therapeutic applications. Wade was appointed a senior scientist (ST) in the Materials Directorate of the Wright Laboratory in 1995. Prior to that he was a research leader and in-house research scientist in the directorate. For the past 36 years he has conducted research in polymer physics, concentrating on structure-property relations in high-performance organic materials. He is internationally known for his research in high-performance rigid-rod polymer fibers, X-ray scattering studies of fibers and liquid crystalline films, polymer dispersed liquid crystals, and theoretical studies of ultimate polymer properties.

In this episode of O Wow Moments from the Children's Museum of Houston, Mr. O is up against the supervillain Dr. Blot and his desire to stain everyone! Actually, it's just a fun excuse to examine how nanotechnology and nanoscale science are applied to create clothes that are stain resistant using nature's lotus leaf as inspiration!
The Blue Morpho Butterfly wing is a nanotechnology marvel! Let's zoom into the wing where we'll see color producing nano-sized structures!
Please watch this video first www.youtube.com MichalChik wrote and provideds link which will be included with this and the entire script What I can say is the your basic idea is feasible if you replace blimps with stratospheric aerosols which is what all the geoengineerinbg stuff is about. One plane can generate the shade ability of a balloon in a fraction of a second and for pennies. en.wikipedia.org 1)The main problems i see are in the technical details, mother natures uncooperativeness and scale. The balloon would tend to drift to jet stream levels in the atmosphere which would mean they would be pushed along at hundreds of miles per hour in unpredictable directions. squall.sfsu.edu 2) The difficulty of steering a balloon increases proportionately to its cross-sectional area.. 1000 balloons to cover a square kilometer is roughly 1000 meters/ sqrt(1000) = 32 meter diameter balloons. (104 feet). Which makes each one wider and more than half as long a the good year blimp. 3) The latest good year blimps cost around 21 million dollars, www.dailybreeze.com 4) Hurricanes are huge. Take a small one with a radius of 100 km it would cover an area of Pi R^2 or 30000 sq KM that would mean 30000 x 1000 = 30000000 (30 million) of your balloons. At 21000000 a balloon that would be about 63 trillion dollars. ravindurkson who is a junior level mechanical engineering student. wrote A hurricane is essentially the cyclone that you are describing.

How does Nanotechnology help when we're on the go? Watch this film to find out!
In this episode of O Wow Moments featuring Mr. O from the Children's Museum of Houston, we play a little game called "Guess That Smell!" where we explore how our sense of smell works. It turns out that we are nanosensors - our noses actually sense molecues - things close to a billionth of a meter in size! But, as you'll see in this video, be careful about with whom you play the game...
