NIST scientists have devised and modeled a unique optical method of sorting microscopic and nanoscopic particles by size, with a resolution as fine as 1 nanometer (nm) for particles of similar ...

Sorting activities such as this one help build early math and critical thinking skills. Write "Big" and "Little" on the two pieces of paper. For advanced learning, add additional pieces of paper for ...

Engineers at Yale University have developed a new, highly efficient technique for separating, sorting, and concentrating synthetic microscopic particles within complex fluids based on size. The new ...

(Nanowerk Spotlight) The precise positioning of nanoparticles on surfaces is key to most nano- technology applications especially molecular electronics. However, for automated patterning of particles, ...
