A metric prefix is a unit prefix that precedes a basic unit of measure to indicate a multiple or submultiple of the unit. All metric prefixes used today are decadic.Each prefix has a unique symbol that is prepended to any unit symbol.
In April 2013, Garvey Spacecraft was awarded a US$200,000 contract to evolve their Prospector 18 suborbital launch vehicle technology into an orbital nanosat launch vehicle capable of delivering a 10 kg (22 lb) payload into a 250 km (160 mi) orbit to an even-more-capable clustered "20/450 Nano/Micro Satellite Launch Vehicle" (NMSLV) capable of ...
Nano (symbol n) is a unit prefix meaning one billionth. Used primarily with the metric system, this prefix denotes a factor of 10 −9 or 0.000 000 001. It is frequently encountered in science and electronics for prefixing units of time and length. Examples. Three gold atoms lined up are about one nanometer (nm) long.
Arguably the biggest potential application of nanocircuits deals with computers and electronics. Scientists and engineers are always looking to make computers faster. Some think in the nearer term, we could see hybrids of micro-and nano-: silicon with a nano core—perhaps a high-density computer memory that retains its contents forever. [20]
Upconverting nanoparticles (UCNPs) are nanoscale particles (diameter 1–100 nm) that exhibit photon upconversion.In photon upconversion, two or more incident photons of relatively low energy are absorbed and converted into one emitted photon with higher energy.
Particle with dimensions between 1 × 10 −7 and 1 × 10 −4 m.. Note 1: The lower limit between micro- and nano-sizing is still a matter of debate.. Note 2: To be consistent with the prefix “micro” and the range imposed by the definition,
Nanotechnologies are based on physical processes which occur on a scale of nanometres (see nanoscopic scale). [1]The nanometre is often used to express dimensions on an atomic scale: the diameter of a helium atom, for example, is about 0.06 nm, and that of a ribosome is about 20 nm.
Micro (Greek letter μ, mu, non-italic) is a unit prefix in the metric system denoting a factor of 10 −6 (one millionth). [1] It comes from the Greek word μικρός (mikrós), meaning "small". [2] It is the only SI prefix which uses a character not from the Latin alphabet.
