[32] [33] [34] For example, silicon and germanium quantum dots have been synthesized by using nonthermal plasma. The size, shape, surface and composition of quantum dots can all be controlled in nonthermal plasma. [35] [36] Doping that seems quite challenging for quantum dots has also been realized in plasma synthesis.
Physical map of Earth Political map of Earth. A map is a symbolic depiction emphasizing relationships between elements of some space, such as objects, regions, or themes.. Many maps are static, fixed to paper or some other durable medium, while others are dynamic or interactive.
An EPC RFID tag used by Wal-Mart.. The Electronic Product Code (EPC) is designed as a universal identifier (using an idiosyncratic numerical code for each different commodity [1]) that provides a unique identity for every physical object anywhere in the world, for all time.

This is a list of the world's countries and their dependencies by land, water, and total area, ranked by total area. The entries in this list include, but are not limited to, those in the ISO 3166-1 standard, which includes sovereign states and dependent territories.
Chart of the Morse code 26 letters and 10 numerals [1]. This Morse key was originally used by Gotthard railway, later by a shortwave radio amateur [2]. Morse code is a telecommunications method which encodes text characters as standardized sequences of two different signal durations, called dots and dashes, or dits and dahs.
User agents center glyphs vertically in an inline box, which adds half-leading on the top and bottom. For example, if a piece of text is "12pt" high and the line-height value is "14pt", 2pt of extra space should be added: 1pt above and 1pt below the text (this applies to empty boxes as well, as if the empty box contained zero-height text).

The need for color discrimination is further impacted by color vision deficiencies; for example, color schemes that use red and green to distinguish values will not be useful for a significant portion of the population. [29] The most common types of color progressions used in choropleth (and other thematic) maps include: [30] [31]
