Amina Khan Deep in the solidified lava beneath Iceland, scientists have managed an unprecedented feat: They’ve taken carbon dioxide released by a power plant and turned it into rock at a rate much faster than laboratory tests predicted. The findings , described in the journal Science, demonstrate a powerful method of carbon storage that could reduce some of the human-caused greenhouse gas emissions contributing to climate change. “These are really exciting results,” said Roger Aines, a geochemist at Lawrence Livermore National Laboratory who was not involved in the study. “Nobody had ever actually done a large-scale experiment like they’ve done, under the conditions that they did it.” See the most-read stories in Science this hour » The pilot program, performed at Reykjavik Energy’s geothermal power plant under a European-U.S. program called CarbFix, was able to turn more than 95% of carbon dioxide injected into the earth into chalky rock within just two year...
The Beginning Xerox was founded in 1906 in New York. The company was called The Haloid Photographic Company which produced photographic paper and equipment. The name was preserved until 1961 when the company was renamed Xerox. Xerox released the first photocopier – Xerox 914 - in 1959. The product was very successful, bringing revenues of $60 million US dollars by the end of 1961. In 1963, Xerox launched the first desktop copier. Many other releases followed establishing Xerox as a leading office solutions provider. Canon was founded in 1937 in Tokyo, Japan. The company manufactured cameras, photocopiers, steppers and computer printers. Canon launched the first photocopier Canofax 1000 in 1965. They released various models which were considered innovative and produced good sales, but they still faced heavy competition from Xerox. With a new managing director and the new color photocopier, Canon had a growth in sales between 1975 and 1985. This continued to bring important revenues...
A laser diode is a laser whose active medium is a semiconductor similar to that found in a light-emitting diode . The most common type of laser diode is formed from a p-n junction and powered by injected electric current . The former devices are sometimes referred to as injection laser diodes to distinguish them from optically pumped laser diodes.
