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.
To understand long-range interactions between particles at the micrometric scale, researchers utilize methods which are used to study the formation of our universe.
Microscopic spheres form strings in surprising alignments when suspended in a viscous fluid and sheared between two plates — a finding that will affect the way scientists think about the properties of such wide-ranging substances as shampoo and futuristic computer chips.
By studying the behavior of tiny particles at an interface between oil and water, researchers at Harvard have discovered that stabilized emulsions may take longer to reach equilibrium than previously thought.
Nanoparticles of a substance can be counted and the size distribution can be determined by dispersing the nanoparticles into a gas.
If you had the choice between a product that you had to shake before use and one that came premixed, you'd probably buy the one that was easier to use and worked best.
- A pivoted catch designed to fall into a notch on a ratchet wheel so as to allow movement in only one direction (e.g. on a windlass or in a clock mechanism), or alternatively to move the wheel in one direction.
