Posted on July 11, 2009 by Shane ENanoparticle Scattering Improves Laser Performance
Posted on July 11, 2009 by Shane E“Light scattering” and “optical performance” are two concepts that usually head in opposite directions, but they have recently been shown to walk happily hand-in-hand. The results are impressive laser output from some new composite materials and the potential for making commercially viable solid-state dye lasers.
Nonstick and laser safe gold aids laser trapping of biomolecules
Posted on July 11, 2009 by Shane EBiophysicists long for an ideal material - something more structured and less sticky than a standard glass surface - to anchor and position individual biomolecules. Gold is an alluring possibility, with its simple chemistry and the ease with which it can be patterned. Unfortunately, gold also tends to be sticky and can be melted by lasers
Laser Created Temporal Lens Could Lead to Movies of Molecular Processes
Posted on October 15, 2009 by Shane EA team at the University of Nebraska-Lincoln has figured out a possible way to observe and record the behavior of matter at the molecular level. That ability could open the door to a wide range of applications in ultrafast electron microscopy used in a large array of scientific, medical and technological fields
Laser Tattoo Removal
Posted on July 6, 2009 by Shane ELasers have been developed in recent decades specifically to treat and remove marks from human skin. Laser treatment is now the standard method of removal for unwanted tattoos. Laser removal is low risk, non-invasive, and has a very low incidence of scarring (about 5%).
Make Solar Panels Easily
Posted on July 6, 2009 by Abeeb CohenA solar energy panel changes the energy from sun's rays into electricity. With the help of regular parts found close to your place, you too can create a solar energy panel and generate electricity. The most clean form of replenish-able energy for use, solar electricity will greatly help reduce your power bill.

Earth4energy a Scam or moneysaver
Posted on July 5, 2009 by Ben kTonight, the world over, people are on the lookout for backup sources of energy. The reason is because of 2 major main reasons. First, the first sources of energy are becoming more expensive by the hour. Second , also they are decreasing at a very fast paste. Almost all of the countries are busy looking for renewable sources of energy, so that their accelerating energy demands can be met. At the grassroots level also, the people are battling to keep their energy bills low. ...

Three Reasons Why Humanoids Will Someday Replace Humans as Soldiers
Posted on July 3, 2009 by Andrew NewellA humanoid is essentially a general-purpose robot that looks a lot like a human person. Not by mere face only, but complete with a head, torso, arms, and legs. A humanoid can therefore walk, or even run like a person, and use its arms and hands to lift objects. At present, a lot of prototypes are being used for different functions. For instance, the Honda ASIMO can deliver coffee and politely shake hands with anyone. Or, the newly updated Twendy-One can prepare a club house sandwich for its mast
