1,3-Butadiene
1,3-Butadiene () is the organic compound with the formula (CH2=CH)2. It is a colorless gas that is easily condensed to a liquid. It is important industrially as a precursor to synthetic rubber. The molecule can be viewed as the union of two vinyl groups. It is the simplest conjugated diene. Although butadiene breaks down quickly in the atmosphere, it is nevertheless found in ambient air in urban and suburban areas as a consequence of its constant emission from motor vehicles. The name butadiene can also refer to the isomer, 1,2-butadiene, which is a cumulated diene with structure H2C=C=CH−CH3. This allene has no industrial significance. History In 1863, the French chemist E. Caventou isolated butadiene from the pyrolysis of amyl alcohol. This hydrocarbon was identified as butadiene in 1886, after Henry Edward Armstrong isolated it from among the pyrolysis products of petroleum. In 1910, the Russian chemist Sergei Lebedev polymerized butadiene and obtained a material wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Georgia Tech
The Georgia Institute of Technology, commonly referred to as Georgia Tech or, in the state of Georgia, as Tech or The Institute, is a public research university and institute of technology in Atlanta, Georgia. Established in 1885, it is part of the University System of Georgia and has satellite campuses in Savannah, Georgia; Metz, France; Shenzhen, China; and Singapore. The school was founded as the Georgia School of Technology as part of Reconstruction plans to build an industrial economy in the post-Civil War Southern United States. Initially, it offered only a degree in mechanical engineering. By 1901, its curriculum had expanded to include electrical, civil, and chemical engineering. In 1948, the school changed its name to reflect its evolution from a trade school to a larger and more capable technical institute and research university. Today, Georgia Tech is organized into six colleges and contains about 31 departments/units, with emphasis on science and technology. I ...

Civil Rights Movement
The civil rights movement was a nonviolent social and political movement and campaign from 1954 to 1968 in the United States to abolish legalized institutional Racial segregation in the United States, racial segregation, Racial discrimination in the United States, discrimination, and disenfranchisement in the United States, disenfranchisement throughout the United States. The movement had its origins in the Reconstruction era during the late 19th century, although it made its largest legislative gains in the 1960s after years of direct actions and grassroots protests. The social movement's major nonviolent resistance and civil disobedience campaigns eventually secured new protections in federal law for the civil rights of all Americans. After the American Civil War and the subsequent Abolitionism in the United States, abolition of slavery in the 1860s, the Reconstruction Amendments to the United States Constitution granted emancipation and constitutional rights of citizenship ...

Assassination Of Martin Luther King Jr
Martin Luther King Jr., an African-American clergyman and civil rights leader, was fatally shot at the Lorraine Motel in Memphis, Tennessee, on April 4, 1968, at 6:01 p.m. CST. He was rushed to St. Joseph's Hospital, where he died at 7:05 p.m. He was a prominent leader of the civil rights movement and a Nobel Peace Prize laureate who was known for his use of nonviolence and civil disobedience. James Earl Ray, a fugitive from the Missouri State Penitentiary, was arrested on June 8, 1968, at London's Heathrow Airport, extradited to the United States and charged with the crime. On March 10, 1969, he pleaded guilty and was sentenced to 99 years in the Tennessee State Penitentiary. He later made many attempts to withdraw his guilty plea and to be tried by a jury, but was unsuccessful. Ray died in prison in 1998. The King family and others believe that the assassination was the result of a conspiracy involving the U.S. government, the mafia, and Memphis police, as alle ...

Historically Black Colleges And Universities
Historically black colleges and universities (HBCUs) are institutions of higher education in the United States that were established before the Civil Rights Act of 1964 with the intention of primarily serving the African-American community. Most of these institutions were founded in the years after the American Civil War and are concentrated in the Southern United States. During the period of segregation prior to the Civil Rights Act, the majority of American institutions of higher education served predominantly white students, and disqualified or limited black American enrollment. For a century after the end of slavery in the United States in 1865, most colleges and universities in the Southern United States prohibited all African Americans from attending, while institutions in other parts of the country regularly employed quotas to limit admissions of Black people. HBCUs were established to provide more opportunities to African Americans and are largely responsible for esta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aromatic Molecule
Aromatic compounds, also known as "mono- and polycyclic aromatic hydrocarbons", are organic compounds containing one or more aromatic rings. The parent member of aromatic compounds is benzene. The word "aromatic" originates from the past grouping of molecules based on smell, before their general chemical properties are understood. The current definition of aromatic compounds does not have any relation with their smell. Heteroarenes are closely related, since at least one carbon atom of CH group is replaced by one of the heteroatoms oxygen, nitrogen, or sulfur. Examples of non-benzene compounds with aromatic properties are furan, a heterocyclic compound with a five-membered ring that includes a single oxygen atom, and pyridine, a heterocyclic compound with a six-membered ring containing one nitrogen atom. Hydrocarbons without an aromatic ring are called aliphatic. Benzene ring model Benzene, C6H6, is the least complex aromatic hydrocarbon, and it was the first one nam ...

Bicyclic Molecule
In chemistry, a bicyclic molecule () is a molecule that features two joined rings. Bicyclic structures occur widely, for example in many biologically important molecules like α-thujene and camphor. A bicyclic compound can be carbocyclic (all of the ring atoms are carbons), or heterocyclic (the rings' atoms consist of at least two elements), like DABCO. Moreover, the two rings can both be aliphatic (''e.g.'' decalin and norbornane), or can be aromatic (''e.g.'' naphthalene), or a combination of aliphatic and aromatic (''e.g.'' tetralin). Three modes of ring junction are possible for a bicyclic compound: * In spirocyclic compounds, the two rings share only one single atom, the spiro atom, which is usually a quaternary carbon. An example of a spirocyclic compound is the photochromic switch spiropyran. * In fused/condensed bicyclic compounds, two rings share two adjacent atoms. In other words, the rings share one covalent bond, ''i.e.'' the so-called bridgehead atoms are direc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The two consolidated in 1988 to form Clark Atlanta University. Atlanta University In the city of Atlant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuclear Magnetic Resonance
Nuclear magnetic resonance (NMR) is a physical phenomenon in which nuclei in a strong constant magnetic field are perturbed by a weak oscillating magnetic field (in the near field) and respond by producing an electromagnetic signal with a frequency characteristic of the magnetic field at the nucleus. This process occurs near resonance, when the oscillation frequency matches the intrinsic frequency of the nuclei, which depends on the strength of the static magnetic field, the chemical environment, and the magnetic properties of the isotope involved; in practical applications with static magnetic fields up to ca. 20 tesla, the frequency is similar to VHF and UHF television broadcasts (60–1000 MHz). NMR results from specific magnetic properties of certain atomic nuclei. Nuclear magnetic resonance spectroscopy is widely used to determine the structure of organic molecules in solution and study molecular physics and crystals as well as non-crystalline materials. ...

Jeannette Brown
Jeannette Elizabeth Brown (born May 13, 1934) is a retired American organic medicinal chemist, historian, and author. Life and education Brown was born in 1934 in The Bronx, New York. According to Brown, when she was young, she contracted tuberculosis, and was treated by Arthur Logan. Logan was a young African-American in his intern year of residency, and lived in Brown's building. Brown's later inspiration to study science came from asking Logan how one could become a doctor. He replied, "Oh, you study science". Brown excelled in particular in chemistry, scoring 98 out of 100 on the New York State Regents chemistry exam. She attended New Dorp High School on Staten Island, and graduated in 1952. Brown earned her bachelor's degree in chemistry at Hunter College in 1956, one of two African Americans in the inaugural class of Hunter's chemistry program.
