micro-, micr-

One µL is a very tiny drop of water.

Any of several techniques for the production of micro scale devices; especially, the production of semiconductor devices using beams of photons or electrons.

Pollinated by small bees.

A reference to the process of being pollinated by small bees.

1. Also called micrometer, it is the millionth part of a meter. Symbol: μ, mu.
2. In chemistry, it is a colloidal particle whose diameter is between 0.2 and 10 microns.
3. In physics, it is a very small unit of pressure, equal to that exerted by a column of mercury 1μ high.

The links on a microchain drive created by Sandia National laboratories in Albuquerque, New Mexico, USA, and announced in January, 2002, are only 50 micrometers apart.

The microchain is constructed of silicon and is designed to transmit power in micro-electromechanical devices.

A microchain that closely resembles a bicycle chain—except that each link could rest comfortably on a human hair—has been fabricated at the Department of Energy’s Sandia National Laboratories. The distance between chain link centers is 50 microns. The diameter of a human hair is approximately 70 microns.

The term was officially sanctioned as part of the metric system from 1879-1967 and is still used in some fields of activity.
