heavy ion

n.
1. The nucleus of a heavy element, such as gold. When such nuclei are caused to collide at high velocities, new elements are created.
2. A charged microscopic particle that forms when an ion attaches to a dust mote or similar object.

Lead scientist Dr Kamal Datta, from Nasa's Specialised Centre of Research at Georgetown University in Washington DC, said: "With the current shielding technology, it is difficult to protect astronauts from the adverse effects of heavy ion radiation.
The search for a new state of matter and understanding of the conditions of its formation in the extreme conditions of the dense and high-temperature environment is the main goal of the ongoing heavy ion investigations at the CERN LHC experiments such as ALICE, ATLAS, and CMS where heavy-ions are smashed at unprecedented high energies ever reached.
The topics include problems with ultrahigh-energy neutrino interactions, canonical methods in deterministic quantum mechanics, highlights from the Brookhaven National Laboratory and the Relativistic Heavy Ion Collider, the mass hierarchy and physics beyond the standard theory, and another look at quadratic divergences.
While scientists have been (http://www.ibtimes.com/cern-lhc-update-large-hadron-collider-smashes-energy-record-lead-ion-collisions-2201372) successful in recreating this exotic soup during high-energy collisions between heavy ions of gold and lead - carried out in particle accelerators like the Relativistic Heavy Ion Collider and CERN's Large Hadron Collider (LHC) - we still do not have a comprehensive understanding of the inner workings of this ephemeral plasma state.

"This project includes hydrothermal synthesis of nickel ferrite magnetic cores, their doping with silica to prepare the bed for the growth of the zeolite layer on its surface, hydrothermal growth of zeolite layer in the presence of organic templates, and heavy ion elimination test from polluted waters." Results of the research showed that the synthesized nanocomposites had high ability to eliminate lead and cadmium ions from polluted waters.
