Element 110 - no name has been proposed or accepted by lUPAC for element 110. This element was first synthesized in a November 1994 experiment by a multi-national team of scientists working at the Gesellschaft fur Schwerionenforschung (GSI) in Darmstadt, Germany. The scientific teams were from the GSI (Heavy Ion Research Center), Darmstadt, the Joint Institute for Nuclear Research (JINR), Dubna, Russia, Comenius University, Bratislava, Slovakia and the University of Jyvaskyla, Finland. They used the nuclear reaction ° Pb ( Ni, n) 110. The longest half-life associated vdth this unstable element is 1.1 minute 10.

Dubnium - the atomic number is 105 and the chemical symbol is Db. The name derives from the location of the Russian research center, the Joint Institute for Nuclear Research lab in Dubna , Russia. The first synthesis of this element is jointly credited to the American scientific team at the University of California in Berkeley, California imder Albert Ghiorso and the Russian scientific team at the JINR (Joint Institute for Nuclear Reactions) lab in Dubna, Russia, imder Georgi N. Flerov in 1970. The longest half-life associated with this unstable element is 34 second Db. 

The chemical and physical properties of Unq (or rutherfordium) are homologous with the element hafnium ( jHf), located just above it in group 4 (fVB) in the periodic table. It was first claimed to be produced artificially by the Joint Institute for Nuclear Research (JINR) located in Dubna, Russia. The Russian scientists used a cyclotron that smashed a target of plutonium-242 with very heavy ions of neon-22, resulting in the following reaction Pu-242 + jjjNe-22 —> jj, Unq-260 + 4 n-1 (alpha radiation). The Russians named Unq-260 kurcha-tovium (Ku-260) for the head of their center, Ivan Kurchatov. (See details in the next section, History. )... 

A joint Russian and American team of physicists created two new super heavy elements—115 and 113—that provide more support for the island of stability concept. The experiments were conducted between July 14 and August 10 in 2003, but the results of the experiments were not published until February 2004. The experiments were conducted in the Joint Institute of Nuclear Research (JINR) in Dubna, Russia, and also involved the scientists of the Lawrence Berkely National Laboratory located at Berkeley, California. Only four atoms of two isotopes of ununpentium (element 115) were produced, and the results were published in a peer-reviewed scientific journal. Following is the nuclear reaction that produced these four atoms ...

The more recently constructed COMBAS device at the JINR at Dubna, Russia has a significantly larger acceptance and is based on using combined function magnets. The A1200 (now retired) and the A1900(MSU) (shown schematically in Fig. 14.14), RCNP(Osaka), and FRS(GSl) separators are positioned at the beginning of the beam distribution system to allow delivery of radioactive beams to any experimental area.

Superheavy elements are defined as the transactinide elements—elements with an atomic number greater than 103. The current production of new superheavy elements takes place mostly at four locations around the world the Lawrence Berkeley National Laboratory (LBNL) at Berkeley, California the GSI Helmholtz Centre for Heavy Ion Research (GSI) at Darmstadt, Germany the Joint Institute for Nuclear Research (JINR) at Dubna, Russia and the Superheavy Element Laboratory of the Institute of Physical and Chemical Research (RIKEN) at Nishina, Japan. As of 2012, the discoveries of elements 113-118 have all been reported. The discoveries of four of these elements, however, are still awaiting independent confirmation from the other laboratories. 

Element 115— (Ununpentium) On February 2, 2004, it was reported that Element 115 had been discovered at the Joint Institute for Nuclear Research (JINR) in Dubna, Russia. Four...
