Among the main ingredients is helium - 3 (He - 3), a vestige of the Big Bang and nuclear fusion reactions in stars.

An American research team in January discovered a way to initiate nuclear fusion reactions in a process called «fast ignition» by using a high - intensity laser, according to the American Association for the Advancement of Science.

These devices heat the plasma to more than 150 million degrees Celsius, simulating the conditions that cause natural nuclear fusion reactions in stars.

On the other hand, «heavy» elements such as carbon and oxygen are synthesized by nuclear fusion reactions in stars.

All stars, including our sun, will eventually run out of the hydrogen gas that fuels the nuclear fusion reactions in their cores.

In this activity students use E = mc2 to calculate the amount of energy released from nuclear fusion reactions in the Sun.

Not exact matches

This «quarksplosion» would be an even more powerful subatomic analog of the individual nuclear fusion reactions that take place in the cores of hydrogen bombs.

For instance, they were involved in debunking cold fusion in 1991, which was a hypothetical nuclear reaction that could occur around room temperature.

If enough material, mostly in the form of hydrogen gas, accumulates on the surface of the white dwarf, nuclear fusion reactions can occur and intensify, culminating into a cosmic - sized hydrogen bomb blast.

Could these conditions initiate or facilitate nuclear fusion, as suggested in the recent movie «Chain Reaction»?

When the head of the Atomic Energy Commission at the time, Lewis Strauss, infamously quipped in 1954 that electricity would become «too cheap to meter,» he was likely referring to nuclear fusion, not nuclear fission, the atom - splitting reaction that powers conventional nuclear power plants today.

Although they are as common as stars and form in much the same way, brown dwarfs lack the mass necessary to sustain nuclear fusion reactions.

The ability to accurately determine the rate of this H - 17O fusion reaction provides nuclear physicists with another key puzzle piece, alongside direct observations of oxygen elemental and isotopic abundances in stellar atmospheres and in primitive meteorites, to zero in on complete and accurate models of stars.

You have those, you kind of solve a lot of the blanket problems where you have your fusion blast in the center and then it hits a blanket which is basically nuclear waste, depleted waste, and there's a lot of left over energy in that waste; and you have neutrons hit that waste and then that catalyzes further reactions, you get a lot more heat.

And compared to the byproducts of nuclear plants, which remain radioactive for thousands of years, the small amount of radioactive material produced in fusion reactions would remain radioactive for tens of years, Synakowski said.

At the center of the Sun, where its density reaches up to 150,000 kg / m3 (150 times the density of water on Earth), thermonuclear reactions (nuclear fusion) convert hydrogen into helium, releasing the energy that keeps the Sun in a state of equilibrium.

If students reveal in an interest inventory that they enjoy working with digital media, leverage that interest in a science class by using new media to build content literacy — for example, what about Einstein's greatest hits playlist, a digital story about nuclear fusion, a video game that simulates a chemical reaction, or a web page that illustrates the formation of the earth?

In stars, the nuclear reactions are primarily the fusion of hydrogen nuclei to form helium nuclei.

«In the process of undergoing these nuclear fusion reactions, the sun emits large amounts of heat and light.
