Exciton-polariton emission from organic semiconductor optical waveguides

We photo-excite slab polymer waveguides doped with J-aggregating dye molecules and measure the leaky emission from strongly coupled waveguide exciton polariton modes at room temperature. We show that the momentum of the waveguide exciton polaritons can be controlled by modifying the thickness of the excitonic waveguide. Non-resonantly pumped excitons in the slab excitonic waveguide decay into transverse electric and transverse magnetic strongly coupled exciton waveguide modes with radial symmetry. These leak to cones of light with radial and azimuthal polarizations

A Spy of His Own Confession: A Revolution in American Espionage

The most well known spies are usually the ones who were caught. But what about those who took their secret lives to the grave? In the summer of 1778, arguably one of the biggest players in the United States’ fight for independence was released from a rebel-controlled prison in Connecticut. Abraham Woodhull, arrested earlier in the year for smuggling, was offered his freedom in exchange for his loyalty to the continental army. His friend, Major Benjamin Tallmadge, was looking to replace the dated espionage methods employed by his superior officer and contentious rival. In just a few short years, the organization they created would change the tide of the war – and all of espionage – forever

A Decade of Downfall: The Industrial and Financial Self-Destruction of the American Automobile Industry Through 2009

This paper examines the developments that lead up to the government bailout of General Motors and Chrysler in 2009. The purpose is to examine and discover the historical, industrial and financial factors that drove American cars into the ground. In today’s society, the perception is that foreign automobiles are superior to domestic vehicles. This comes half a century after culture in the United States circulated around the American automobile. The American big business techniques built a manufacturing empire, differentiated the US from the foreigners and then weakened the long-term development of the automotive industry. Financialization became a support in an attempt to support a crumbling system. Each individual strategy was successful in the short term but came together to negatively influence the long-term industry. These elements conclude a self-destructive fate of the US automobile manufacturers. The bailout was not the fault of the nation but rather the responsibility of the Big Three

The NISE Net: Bringing the Study of the Very Small to US Science Centers

With funding from NSF, the Nanoscale Informal Science Education Network aims to use informal learning experiences to engage families, schoolchildren, and adults in nanoscale science, engineering, and technology in science centers and museums across the US
