Glossary of Terms
A

Many of the most useful diamondoid structures will in fact be rich in tetrahedrally coordinated carbon. Materials with superior strength to weight ratio, as much as 100 to 250 times as strong as Titanium, and much lighter. Possibly used to build stronger lighter rockets and space components, or a variety of other earth-bound articles for which weight and strength are a consideration

Dry Nanotechnology – derives from surface science and physical chemistry, focuses on fabrication of structures in carbon (e.g. fullerenes and nanotubes), silicon, and other inorganic materials. Unlike the “wet” technology, “dry” techniques admit use of metals and semiconductors. The active conduction electrons of these materials make them too reactive to operate in a “wet” environment, but these same electrons provide the physical properties that make “dry” nanostructures promising as electronic, magnetic, and optical devices. Another objective is to develop “dry” structures that possess some of the same attributes of the self-assembly that the wet ones exhibit. [Rice University]

It results from subtle electron-spin effects in ultra-thin ‘multilayers’ of magnetic materials, which cause huge changes in their electrical resistance when a magnetic field is applied. GMR is 200 times stronger than ordinary magnetoresistance. [See Spintronics and Giant Magneto Resistance] GMR enables sensing of significantly smaller magnetic fields, which in turn allows hard disk storage capacity to increase by a factor of 20
Golden Goo - another member of the grey goo family of nanotechnology disaster scenarios. The idea is to use nanomachines to filter gold from seawater. If this process got out of control we would get piles of golden goo (the “Wizard’s Apprentice Problem”). This scenario demonstrates the need of keeping populations of self-replicating machines under control; it is much more likely than grey goo, but also more manageable. [AS - Originated on sci.nanotech 1996]

You want to take a vacation – it knows that you really enjoyed that trip to Hawaii, and that you prefer to fly at night, 1st class. It also knows that the bungalow you rented last time was marked as being 5-star, and worth a re-visit. Your IA then collates all your parameters, searches the internet for flights, car rentals, restaurant reservations, and lodgings, and schedules everything for you, with options on the side. No more travel agent – you have a software agent to handle things! Many experts agree that by 2010 we will each have one, and that they will greatly reduce our daily load of trivial and redundant tasks

LCD (Liquid Crystal Display) – is the predominant technology used in flat panel displays. The principle that makes the display work is this: A crystal alignment can be altered with an electric current. If the crystal is lined up one way ñ it will allow the light waves to pass through a polarized filter, but if the electric current alters the crystal 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, 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

A mouthful of water, roughly 5 cm^3, would have the same mass as a ~2 terabot (2 trillion nanites) dose of 1 micron^3 nanorobots. You’ll never feel it.” Robert A. Freitas Jr. “Nanobot” and “Nanorobot” usually mean the same thing
Nano – Greek for “dwarf,” meaning one billionth
Nanocrystals – also known as nanoscale semiconductor crystals. “Nanocrystals are aggregates of anywhere from a few hundred to tens of thousands of atoms that combine into a crystalline form of matter known as a “cluster.” Typically around ten nanometers in diameter, nanocrystals are larger than molecules but smaller than bulk solids and therefore frequently exhibit physical and chemical properties somewhere in between. Given that a nanocrystal is virtually all surface and no interior, its properties can vary considerably as the crystal grows in size”

Picture also a “space elevator”. In theory, constructed of a diamondoid material, approximately 22,000 miles long, with one end in a stable orbit, and the other somewhere [probably] around the equator. Used frequently in science-fiction yarns, and may become a reality with the advent of mature MNT. Such an elevator would move freight and passengers into orbit at a cost per pound orders of magnitude less than current launches, with passenger safety comparable to train, plane, or subway trips. Becomes possible when we can mass-produce nanotubes, and make their length to fit.

In describing the energies, distributions and behaviors of electrons in nanometer-scale structures, quantum mechanical methods are necessary. Electron wave functions help determine the potential energy surface of a molecular system, which in turn is the basis for classical descriptions of molecular motion. Nanomechanical systems can almost always be described in terms of classical mechanics, with occasional quantum mechanical corrections applied within the framework of a classical model

Quantum Dot – a semiconductor nanocrystal that exhibits quantum behaviour in optical or electrical processes
Quantum Well – a P-N-P junction in which the “N” layer is ~10 nm (where traditional physics leaves off and quantum effects take over) and an “electron trap” is created. “If one makes a hetero-structure with sufficiently thin layers, quantum interference effects begin to appear prominently in the motion of the electrons. The simplest structure in which these may be observed is a quantum well, which simply consists of a thin layer of a narrower-gap semiconductor between thicker layers of a wider-gap material”
Quantum Wire – another form of quantum dot, but unlike the single-dimension “dot,” a quantum wire is confined only in two dimensions – that is it has “length,” and allows the electrons to propagate in a “particle-like” fashion. Constructed typically on a semiconductor base, and (among other things) used to produce very intense laser beams, switchable up to multi-gigahertz per second

Smart Materials – here, materials and products capable of relatively complex behavior due to the incorporation of nanocomputers and nanomachines. Also used for products having some ability to respond to the environment. [NTN] If you combined microscopic motors, gears, levers, bearing, plates, sensors, power and communication cables, etc., with powerful microscopic computers, you have the makings of a new class of materials: “smart materials.” Programmable smart materials could shape-shift into just about any desired object. A house made of smart materials would be quite useful and interesting. Imagine a wall changing color at your command, or making a window where their was none before

Terraform – to change the properties of a planet to make it more earthlike, making it possible for humans or other terrestrial organisms to live unaided on it, for example by changing atmospheric composition, pressure, temperature or the climate and introducing a self-sustaining ecosystem. This will most probably be a very long-term project, probably requiring self-replicating technology and megascale engineering. So far Venus and especially Mars look as the most promising candidates for terraforming in the solar system. [Jack Williamson 1938] Speculation exists that with the advent of mature MNT that we should be able to accomplish Terraforming a planet such as Mars in years, rather then decades

Universal Assembler – uses raw atoms and molecules to construct consumer goods, and is pollution free. Can be programmed to build anything that is composed of atoms and consistent with the rules of chemical stability. Eric Drexler talks about these assemblers as nanorobots with telescoping manipulator arms that are capable of picking up individual atoms, and combining them however they are programmed

The success of this nanotechnology is amply demonstrated by the existence of living organisms whose form, function, and evolution are governed by the interactions of nanometer-scale structures
Z
Zeptosecond - one-billion-trillionth of a second, or 10 -21 second. Because nuclear movement takes place so quickly, scientists would need a pulse of light lasting just one zeptosecond to observe them
Zettatechnology – in which zetta means 1021, referring to the typical number of distinct designed parts in a product made by the systems we envision (molecular, mature, or molecular-manufacturing-based nanotechnology).
