Size matters when reducing NiO nanoparticles
(Phys.org)—New research finds that size plays a major role in how nanoscale nickel oxide (NiO) shells behave when being reduced to solid nickel nanoparticles.
New study reveals challenge facing designers of future computer chips
To build the computer chips of the future, designers will need to understand how an electrical charge behaves when it is confined to metal wires only a few atom-widths in diameter.
Researchers create new microparticles that self-assemble like atoms into molecules
Scientists have created new kinds of particles, 1/100th the diameter of a human hair, that spontaneously assemble themselves into structures resembling molecules made from atoms. These new particles come ...
NGC 3344: Hubble sees galaxy in a spin
(Phys.org)—NGC 3344 is a glorious spiral galaxy around half the size of the Milky Way, which lies 25 million light-years distant. We are fortunate enough to see NGC 3344 face-on, allowing us to study its ...
