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.

Organic chemistry is the study of the structure, properties, composition, reactions, and preparation of carbon-containing compounds, which include not only hydrocarbons but also compounds with any number of other elements, including hydrogen (most compounds contain at least one carbon–hydrogen bond), nitrogen, oxygen, halogens, phosphorus, silicon, and sulfur. This branch of chemistry was originally limited to compounds produced by living organisms but has been broadened to include human-made substances such as plastics. The range of application of organic compounds is enormous and also includes, but is not limited to, pharmaceuticals, petrochemicals, food, explosives, paints, and cosmetics.
Organic chemists at all degree levels are found in all those industries that depend on R&D, working on projects from fundamental discovery to highly applied product development. The foundation of the pharmaceutical industry is the large pool of highly skilled organic chemists. For example, nature may provide a molecule such as a complex antibiotic, an antitumor agent, or a replacement for a hormone such as insulin; organic chemists determine the structure of this newly discovered molecule and then modify it to enhance the desired activity and specificity of action, while decreasing undesired side effects. Indeed, organic chemists have produced a wonderful myriad of highly successful products to fight human diseases.
There is tremendous excitement and challenge in synthesizing a molecule never before made synthetically or found in nature. Tailoring the properties of that molecule via chemical synthesis to produce beneficial effects to meet the needs of the present and future human existence is both challenging and rewarding.
Organic chemistry is a highly creative science in which chemists
create new molecules and explore the properties of existing compounds.
It is the most popular field of study for ACS chemists and Ph.D.
chemists.
Organic compounds are all around us. They are central to the economic
growth of the United States in the rubber, plastics, fuel,
pharmaceutical, cosmetics, detergent, coatings, dyestuff, and
agrichemical industries, to name a few. The very foundations of
biochemistry, biotechnology, and medicine are built on organic compounds
and their role in life processes. Many modern, high-tech materials are
at least partially composed of organic compounds. Organic chemists spend much of their time creating new compounds and
developing better ways of synthesizing previously known compounds
