(PhysOrg.com) -- Using photons instead of electrons to transmit information could lead to faster and more secure ways to communicate, among other advantages. Now a team of physicists has taken another step toward realizing quantum photonic technologies by demonstrating how to quickly manipulate single photons at the same wavelengths used in existing optical telecommunications networks. The ability to control a photon’s path and polarization in the time of a few nanoseconds could allow photonic circuits to be integrated with existing optical telecom networks, leading to significant improvements.

(PhysOrg.com) -- Over the past several years, organic light-emitting diodes (OLEDs) have become a popular light source due to their advantages including bright displays, wide viewing angles, and the ability to be printed on flexible substrates. A lesser known alternative to OLEDs, which has these advantages plus some additional ones such as low turn-on voltage, is electrochemical light-emitting cells (LECs).

The best businesspeople don't know everything. They're the ones who are brave and truthful enough to admit mistakes--and learn the most from them along the way

Solar Ivy's panels aren't your typical gray slabs. They might actually improve the appearance of a house. Solar panels don't tend to win beauty contests.

A 501(c)(3) nonprofit can still generate earned income. And plenty do. The National Center for Charitable Statistics estimates that nearly 70 percent of the $1.4 trillion generated by nonprofits in 2008 came from the sale of goods and services.
