We demonstrate that the very low lattice thermal conductivity achieved is attributed to phonon scattering at high-contrast atomic mass solute atoms rather than from the contribution of secondary phases.
He also has suggested upending decades of U.S. efforts aimed at stopping the spread of nuclear weapons by suggesting Japan and South Korea should build their own atomic arsenal rather than rely on the U.S. nuclear umbrella.
Quantum spin, though of atomic nuclei rather than of electrons, would be the ideal basis for this hardware.
The particles are made of atomic nuclei rather than the usual X-rays, and theoretically can be focused more precisely on cancerous tissue, minimizing the danger to healthy tissue surrounding it.
Time measurements are now based on atomic clocks rather than on Earth's rotation, and telescopes can be driven continuously to compensate for the planet's rotation, so as to permit tracking of a given astronomical object.
When I read that "the universe is 13.7 billion years old," I wonder: Don't scientists use some more universal measurement than years, something not tied to the orbit of one tiny planet? A. Modern measurement of time builds on the second, based on atomic oscillation, rather than on the variable time it takes the Earth to orbit the Sun.
Complex, in chemistry, a substance, either an ion or an electrically neutral molecule, formed by the union of simpler substances (as compounds or ions) and held together by forces that are chemical (i.e., dependent on specific properties of particular atomic structures) rather than physical.
Essentially a proton battery is a reversible PEM fuel cell with an integrated solid-state electrode for storing hydrogen in atomic form, rather than as molecular gaseous hydrogen in an external cylinder.
The advantage of using atomic polarizabilities rather than the whole molecular ones, is that we can extract separate information about the role of each functional group in the molecule, which is very important to design new molecules.
Being uncharged, neutrons scatter much more readily from the atomic nuclei rather than from the electrons.
