Kent, Ohio (UPI) Dec 18, 2006 U.S. scientists say changing the size of colloids -- micro- or nanometer-sized particles -- makes a big difference in the properties of liquid crystals. Kent State University scientists say they've demonstrated when the concentration and size of the colloids and liquid crystals are properly tuned, the systems formed promise a new technique for synthesizing liquid crystals with specific molecular properties. The researchers said the ferroelectric nanoparticles have a significant impact on the material properties of the liquid crystal host. And they are stable in the liquid crystals and invisible to naked eye. Manipulation of such systems, said the researchers, also leads to a reduction in the amount of power required to run liquid crystal displays, such as computer screens, and could result in creation of a range of different liquid crystal materials for a wide variety of applications. The study appeared in a recent issue of the journal Physical Review Letters. Community Email This Article Comment On This Article Related Links Space Technology News - Applications and Research
Wallops Demonstrates Capabilities With TacSat-2 And GeneSat-1 Launch
Washington DC (SPX) Dec 18, 2006TacSat-2 launched successfully at 7 a.m. EST on Saturday, Dec. 16. TacSat-2 will be propelled into a circular orbit approximately 255 miles above the Earth by a Minotaur I launch vehicle. The satellite, housed in a shroud atop the rocket, will be released into space between 100,000 and 150,000 feet altitude, and will share the brief ride into the cosmos with NASA's GeneSat-1. |
