A chain reaction is a sequence of reactions where a reactive product or by-product causes additional reactions to take place. In a chain reaction, positive feedback leads to a self-amplifying chain of events. Chain reactions are one way that systems which are not in thermodynamic equilibrium can release energy or increase entropy in order to ...
Chain Reaction is a 1996 American science fiction action thriller film directed by Andrew Davis and starring Keanu Reeves, Morgan Freeman, Rachel Weisz, Fred Ward, Kevin Dunn and Brian Cox. The plot centers on the invention of a new non-contaminating power source based on hydrogen and the attempts by the United States Government to prevent the ...
Since nuclear chain reactions may only require natural materials (such as water and uranium, if the uranium has sufficient amounts of 235 U), it was possible to have these chain reactions occur in the distant past when uranium-235 concentrations were higher than today, and where there was the right combination of materials within the Earth's crust.
Chain Reaction is an American television game show created by Bob Stewart, in which players compete to form chains composed of two-word phrases. The show has been revived four times. Bill Cullen hosted the original series on NBC from January 14, 1980 to June 20, 1980.
The proton–proton chain, also commonly referred to as the p–p chain, is one of two known sets of nuclear fusion reactions by which stars convert hydrogen to helium. It dominates in stars with masses less than or equal to that of the Sun , [ 2 ] whereas the CNO cycle , the other known reaction, is suggested by theoretical models to dominate ...
The termination phase involves the interaction of a radical with an antioxidant molecule, such as α-tocopherol (vitamin E), which inhibits the propagation of chain reactions, thus terminating peroxidation. Another method of termination is the reaction between a lipid radical and a lipid peroxide, or the combination of two lipid peroxide ...
"Chain Reaction" is a song by American singer Diana Ross, released on November 12, 1985 by RCA and Capitol, as the second single from her sixteenth studio album, Eaten Alive (1985). The song was written by the Bee Gees and contains additional vocals from Barry Gibb .
In such cases, the chain reaction can either settle into a low power steady state or may even become either temporarily or permanently shut down (subcritical). In the history of atomic power development, at least 60 criticality accidents have occurred, including 22 in process environments, outside nuclear reactor cores or experimental ...
