Researchers find that you can use hydrogen as an alternative to fossil fuels. As researchers were studying they created a fully scalable type of powder photocatalyst. This kind of powder photocatalyst makes the hydrogen process simpler, easier and cheaper. This powder needs to be at an ambient temperature and pressure. This powder is made by [...]

How it Works: Evaporation
October 20th, 2010 · 2 Comments · Chemistry
For the past 130 years, we thought we had evaporation all figured out. Thanks to a mistake by scientists testing a new program, we now know that we don’t know how evaporation works. 71% of the earth is covered by water and evaporation happens all the time. If there was no evaporation, there would be [...]

The Hunt For Water on Mars
September 17th, 2008 · 2 Comments · Chemistry
Scientists and chemists are all looking for evidence of water on Mars. They have found water ice a few centimeters under the service of the planet. They also have proof of water vapor in the Martian atmosphere. The most important type of water they are trying to find is liquid water. Some scientist say they [...]

Hydrogen Powered Cars
April 6th, 2008 · 3 Comments · Chemistry
In order to create a car that can be completely run on hydrogen, a fuel tank would have to be engineered so that it could either handle extremely high pressures for hydrogen gas, or extremely low pressures for liquid hydrogen to exist within it. Researchers from the NCNR have discovered a group of materials that [...]

Innovative Atom Trap Catches Highly Magnetic Atoms, Cools Atoms To Almost Absolute Zero
April 3rd, 2008 · 1 Comment · Chemistry, Physics
A research team from the National Institute of Standards and Technology (NIST) and the University of Maryland has succeeded in cooling atoms of a rare-earth element, erbium, to within two millionths of a degree of absolute zero using a novel trapping and laser cooling technique. Their recent report* is a major step towards a capability [...]
