A solar-powered airplane finished crossing the United States on Saturday, landing in New York City after flying over the Statue of Liberty during its historic bid to circle the globe, the project team said. The spindly, single-seat experimental aircraft, dubbed Solar Impulse 2, arrived at New York's John F. Kennedy International Airport at about 4 a.m. local time after it took off about five hours beforehand at Lehigh Valley International Airport in Pennsylvania, the team reported on the airplane's website. Such a pleasure to land in New York! For the 14th time we celebrate sustainability," said the project's co-founder Andre Borschberg on Twitter after flying over the city and the Statue of Liberty during the 14th leg of the trip around the globe. The Swiss team flying the aircraft in a campaign to build support for clean energy technologies hopes eventually to complete its circumnavigation in Abu Dhabi, where the journey began in March 2015. The solar cr...
An international team of scientists has agreed to add two new elements to the periodic table, element 114 and element 116. These new elements are the heaviest elements yet to appear on the periodic table, with atomic masses of 289 and 292 atomic mass units, respectively.The existence of these elements has been suspected for quite some time, but required rigorous verification. In 1999, a single atom of element 114 was produced by bombarding plutonium-244 with calcium-48. Element 116 decays into 114, which undergoes alpha decay to become copernicium. The announcement concludes a three year review process, during which time the scientists conducted further experiments to substantiate their claims.
As is traditional, the discoverers of the elements will get the honor of proposing their names. The Dubna team at the Joint Institute for Nuclear Research in Russia has proposed "flerovium" for 114, after Georgy Flyorov, a Soviet scientist who discovered elements. The proposed name for element 116 is "moscovium", after the Russian Moscow region.
Nice references to them who are interested with latest chemistry innovation. nice one !
