Quantum Dot Laser
A quantum dot laser is a semiconductor laser that uses quantum dots as the active laser medium in its light emitting region. Due to the tight confinement of charge carriers in quantum dots, they exhibit an electronic structure similar to atoms. Lasers fabricated from such an active media exhibit device performance that is closer to gas lasers, and avoid some of the negative aspects of device performance associated with traditional semiconductor lasers based on bulk or quantum well active media. Improvements in modulation bandwidth, lasing threshold, relative intensity noise, linewidth enhancement factor and temperature insensitivity have all been observed. The quantum dot active region may also be engineered to operate at different wavelengths by varying dot size and composition. This allows quantum dot lasers to be fabricated to operate at wavelengths previously not possible using semiconductor laser technology. One challenge in the further advances with quantum dot lasers is the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chicago Tribune
The ''Chicago Tribune'' is a daily newspaper based in Chicago, Illinois, United States, owned by Tribune Publishing. Founded in 1847, and formerly self-styled as the "World's Greatest Newspaper" (a slogan for which WGN radio and television are named), it remains the most-read daily newspaper in the Chicago metropolitan area and the Great Lakes region. It had the sixth-highest circulation for American newspapers in 2017. In the 1850s, under Joseph Medill, the ''Chicago Tribune'' became closely associated with the Illinois politician Abraham Lincoln, and the Republican Party's progressive wing. In the 20th century under Medill's grandson, Robert R. McCormick, it achieved a reputation as a crusading paper with a decidedly more American-conservative anti-New Deal outlook, and its writing reached other markets through family and corporate relationships at the ''New York Daily News'' and the ''Washington Times-Herald.'' The 1960s saw its corporate parent owner, Tribune Company, rea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Illinois Central Railroad
The Illinois Central Railroad , sometimes called the Main Line of Mid-America, was a railroad in the Central United States, with its primary routes connecting Chicago, Illinois, with New Orleans, Louisiana, and Mobile, Alabama. A line also connected Chicago with Sioux City, Iowa (1870). There was a significant branch to Omaha, Nebraska (1899), west of Fort Dodge, Iowa, and another branch reaching Sioux Falls, South Dakota (1877), starting from Cherokee, Iowa. The Sioux Falls branch has been abandoned in its entirety. The Canadian National Railway acquired control of the IC in 1998, and merged its operations in 1999. Illinois Central continues to exist as a paper railroad. History The IC was one of the oldest Class I railroads in the United States. The company was incorporated by the Illinois General Assembly on January 16, 1836. Within a few months Rep.

Coal Mine
Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine is called a 'pit', and the above-ground structures are a 'pit head'. In Australia, "colliery" generally refers to an underground coal mine. Coal mining has had many developments in recent years, from the early days of men tunneling, digging and manually extracting the coal on carts to large open-cut and longwall mines. Mining at this scale requires the use of draglines, trucks, conveyors, hydraulic jacks and shearers. The coal mining industry has a long history of significant negative environmental impacts on local ecosystems, health impacts on local communities and workers, and contributes heavily to th ...
