Langmuir-Blodgett: The name of a nanofabrication technique used to create ultrathin films (monolayers and isolated molecular layers),the end result of which is called a "Langmuir-Blodgett film." Moreandmore.
LCD(Liquid Crystal Display) is the predominant technology used in flat panel displays.The principle that makes the display work is this: A crystal�s alignment can be altered with an electric current.If the crystal is lined up one way � it will allow the light vwin徳赢官网waves to pass through a polarized filter,but if the electric current alters the crystal�s alignment,it will guide light so that the polarized filter blocks the light.By densely packing red,blue and green light emitting crystals next to each other on a sheet (�called a substrate�),one can create a full color display.The great thing about LCD is that the crystals can be packed together closely,allowing for a higher-resolution,finer-detail display.The con is that LCDs are somewhat fragile,require a lot of power and are relatively less bright.
LEDs(Light Emitting Diodes) work on a completely different concept.Traditionally LEDs are created from two semiconductors.By running current in one direction across the semiconductor the LED emits light of a particular frequency (hence a particular color) depending on the physical characteristics of the semiconductor used.The semiconductor is covered with a piece of plastic that focuses the light and increases the brightness.These semiconductors are very durable,there is no filament,they don�t require much power,they�re brighter and they last a long time.By densely packing red,blue and green LEDs next to each other on a substrate one can create a display.
The disadvantage of LEDs is that they are much larger � therefore the resolution is not nearly as good as LCD displays.That�s why most LED displays are large,outdoor displays,not smaller devices,like monitors.
OLEDorOrganic LED不是由半导体。It�s made from carbon-based molecules.That is the key science factor that leads to potentially eliminating LEDs� biggest drawback � size.The carbon-based molecules are much smaller.And according to a paper written by Dr.Uwe Hoffmann,Dr.Jutta Trube and Andreas Kl�ppel,entitledOLED - A bright new idea for flat panel displays�OLED is brighter,thinner,lighter,and faster than the normal liquid crystal (LCD) display in use today.They also need less power to run,offer higher contrast,look just as bright from all viewing angles and are - potentially - a lot cheaper to produce than LCD screens.� LCD,LED,and OLED definitions courtesyThe San Francisco Consulting Group (SFCG)
Limited Assembler: Assembler capable of making only certain products;faster,more efficient,and less liable to abuse than a general-purpose assembler.[FS]
Linde Scenario:A scenario for indefinite survival of intelligent life.It assumes it is possible to either createbasement universesconnected to the original universe with awormholeor the existence of other cosmological domains.Intelligent life continually migrates to the new domains as the old grow too entropic to sustain life.[AS/Mitch Porter,1997.The name refers to Linde's chaotic inflation cosmology,where new universes are continually spawned.] SeeThe Linde scenario,v0.01
Lofstrom Loop: An beanstalk-like megaconstruction based on a stream of magnetically accelerated bars linked together.The stream is sent into space,where a station rides it using magnetic hooks,redirects it horizontally to another station,which sends it downwards to a receiving station on the ground.From this station the stream is then sent back to the launch station (a purely vertical version is called a space fountain).This structure would contain a large amount of kinetic energy but could be built gradually and would only require enough energy to compensate for losses when finished.Elevators could be run along the streams,and geostationary installations could be placed along the horizontal top.[Named after Keith Lofstrom,who did the first detailed calculations on it in: Lofstrom,Keith H.,"The launch loop -- a low cost Earth-to-high orbit launch system," AIAA Paper 85-1368,1985].[AS]
Low-dimension Structures: quantum wells,quantum wire and quantum dots.

Matter as Software: "Autonomous,motile microdevicesclearly are on the horizon.They may be regarded as the first step in the evolution of a technology for "programming" the structure and properties of material objects at the microscopic and the submicroscopic levels.As this evolution progresses,the physical and economic properties of such programmable matter are likely to become much like those of present day software."[MITRE Corporation]
Meat Machine: AKA Cabinet Beast.A box containing assemblers and raw material,within which is formed meat [or whatever else it was programmed to make].[FS]
Mechanochemistry: the direct,mechanical control of molecular structure formation and manipulation to form atomically precise products [K.Eric Drexler.FromNanosystems: Molecular Machinery,Manufacturing,and Computation]
Mechanosynthesis: (where) molecular tools with chemically specific tip structures can be used,sequentially,to modify a work piece and build a wide range of molecular structures.[FS] SeeTechnical Bibliography for Research on Positional Mechanosynthesis

MEMS--MicroelectroMechanical Systems: generic term to describe micron scale electrical/mechanical devices.[ZY] SeeThe beauty of MEMS: Simpler,more reliable,cheaper,and cool - Small Timesfor a great description and examples of use.
Mesoscale: A device or structure larger than the nanoscale (10^-9 m) and smaller than the megascale;the exact size depends heavily on the context and usually ranges between very large nanodevices (10^-7 m) and the human scale (1 m).[AS]

Moore's Law-- Coined in 1965 by Gordon Moore,future chairman and chief executive of Intel,it stated at the time that the of number transistors packed into an integrated circuit had doubled every year since the technology's inception four years earlier.In 1975 he revised this to every two years,and most people quote 18 months.The trend cannot continue indefinitely with current lithographic techniques,and a limit is seen in ten to fifteen years.However,the baton could be passed to nanoelectronics,to continue the trend (though the smoothness of the curve will very likely be disrupted if a completely new technology is introduced).[CMP]
