Nanoantennas Could Enable Future Terabit Wireless Optical Quantum Communication

April 7, 2017October 15, 2009 by Brian Wang

For high frequency electromagnetic light waves in the frequency range of several 100,000 gigahertz (500,000 GHz corresponds to yellow light with 600 Nm wavelength), one needs very small antennas, which are not larger than a half light wave length, thus maximally 350 nanometers (1 nanometer = 1 millionth millimeter). The scientists of the DFG Heisenberg …

Half of all Premature Deaths in Russia are Alcohol Related and 4% of Worldwide Deaths are From Alcohol

April 7, 2017June 26, 2009 by Brian Wang

In Russia, 59% of deaths in men and 33% of deaths in women between the ages of 15-54 were caused by alcohol. Most of these alcohol-attributed deaths were from alcohol poisoning, accidents, violence, or one of eight disease groups strongly related to alcohol, such as TB, pneumonia, pancreatitis or liver disease. Professor Sir Richard Peto …
