nu·cle·ar fu·sion

the formation of more complex atomic nuclei from less complex nuclei with release of energy, as in the formation of helium nuclei from hydrogen nuclei (hydrogen fusion).

nuclear fusion

Joining of the nucleus of small atoms to form larger atoms. It occurs when temperatures reach millions of degrees. An example is the nuclear reaction joining hydrogen together to form helium and resulting in the significant release of energy.

Fusion reactions can be induced in a form of matter called plasma, which consists of extremely hot electrically charged gases, and which was the focus of the research.
It is considered that the fusion reaction between the silver nanoparticles would raise the temperature at the silver surfaces, so that the desorption of alkylamine molecules and the fusion reaction between the silver nanoparticles proceed by the avalanche-like process to eventually form a self-fused solid silver layer without voids (Fig.
The pistons surrounding the chamber should slam the metal around the plasma hard enough to set off a fusion reaction.
In general ICF initiates the fusion reaction by heating and compressing the fuel capsule in a pellet form[1].
The hope is to harness the immense energy produced by fusion reactions.
This fusion reaction happens about a million times faster than a stick of dynamite explodes.
Further as one fusion reaction on the average takes 10-10 sec and muon life time 106 sec so theoretically muon can catalyze 104 fusion reactions before its naturally death; but in practice this number has been very low .
Scientists across the world have been trying for decades to harness the energy released by fusion reactions.
SEOUL: North Korea, one of the world s poorest countries, said on Wednesday it had succeeded in creating a nuclear fusion reaction to produce energy, a claim called absurd by nuclear experts.
Seoul, May 12 (BNA) North Korea said Wednesday it succeeded in producing a nuclear fusion reaction, a claim that appeared to be aimed at increasing its bargaining power before the communist state rejoins stalled six nation talks on its nuclear ambitions.
The idea is to use inertia, rather than for example a magnetic field, to confine a fusion reaction just long enough to get really hot.
In 1989, scientists Stanley Pons and Martin Fleischmann of the University of Utah announced that they had initiated a room temperature fusion reaction.
