Researchers have developed an insight that could facilitate production of microscopic carbon nanotubes, structures thousands of times thinner than a human hair used in everything from microchips to sporting goods to pharmaceutical products. The research by scientists at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) could ensure that fabrication forms nanotubes as efficiently as possible.
Nanomaterials, which are measured in billionths of a meter, are prized for their use in everything from golf clubs and swimwear to microchips, paints and pharmaceutical products, thanks to their singular properties. These include exceptional strength and flexibility and high electrical conductivity. Carbon nanotubes, for example, are tens of thousands of times thinner than a human hair, yet are stronger than steel on an ounce-per-ounce basis.
PPPL researchers have launched a nanotechnology laboratory that they envision as a step toward research capabilities that could serve as a resource for institutions and industries around the world.
David Graves, an internationally-known chemical engineer, has been named to lead a new research enterprise that will explore plasma applications in nanotechnology for everything from semiconductor manufacturing to the next generation of super-fast quantum computers.
Creating and controlling on Earth the fusion energy that powers the sun and stars is a key goal of scientists around the world. Production of this safe, clean and limitless energy could generate electricity for all humanity, and the possibility is growing closer to reality. Now a landmark report released this week by the American Physical Society Division of Plasma Physics Community Planning Process proposes immediate steps for the United States to take to accelerate U.S.
From helping the nation’s power grid to advancing the creation of “a star in a jar” for a virtually endless supply of electric power, scientists at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) have developed insights and discoveries over the past year that advance understanding of the universe and the prospect for safe, clean, and abundant energy.
Discoveries and breakthroughs from the past year at the national laboratory for fusion and plasma science research.
Steven Cowley, a theoretical physicist and international authority on fusion energy, became the seventh Director of the Princeton Plasma Physics Laboratory (PPPL) on July 1 and will be Princeton professor of astrophysical sciences on September 1.
Recent findings at PPPL could advance improved manufacturing of nanoparticles in a variety of industries.
New insights into the science of fusion energy and the physics of plasma from researchers at PPPL.
Plasma – the hot ionized gas that fuels fusion reactions – can also create super-small particles used in everything from pharmaceuticals to tennis racquets. These nanoparticles, which measure billionths of a meter in size, can revolutionize fields from electronics to energy supply, but scientists must first determine how best to produce them.
Big Bang neutrinos are believed to be everywhere in the universe but have never been seen. The expansion of the universe has stretched them and they are thought to be billions of times colder than neutrinos that stream from the sun. As the oldest known witnesses or “relics” of the early universe, they could shed new light on the birth of the cosmos if scientists could pin them down. That’s a tall order since these ghostly particles can speed through planets as if they were empty space.
