Related to grapheme: Graphene


A pictorial representation of a semanteme, such as X-reference for cross-reference.



the smallest distinctive unit of written speech, corresponding to the phoneme in oral speech—a, b, and so on. The system of graphemes of a particular writing system makes up the system’s alphabet.

The grapheme must be distinguished from the letter, which corresponds to a sound of speech (A, a, a, and so on), and from a graphic combination (that is, a collection of letters), which is regularly used in the particular writing system to designate a certain phoneme (for example, ch represents the phonemes [#x222B;], [x], and [t∫] in the French, German, and English writing systems, respectively). The term “grapheme” was introduced in 1912 by I. A. Baudouin de Courtenay.

Firstly, the child produced a better representational fit between phonemes and graphemes.
By calculating the propagation of surface plasmons, in the structures that are included single atomic grapheme sheets, separated by an insulting material, we can get that for separation distances about 20 nm, surface plasmons in graphen sheets interact with each other, so that they get together (see gig).
This shows thai monolayer grapheme nanosheets are much more effective in improving Tt of an epoxy system because they can more effectively restrict chain segmental mobility and reduce free volume.
Xu Shen points out when a guwen grapheme has come down unchanged into zhuanwen but is misunderstood because the word that the classifier wrote in guwen has taken on a different graphemic structure in zhuanwen (and hence the guwen grapheme is no longer understood properly as a classifier, because the original classifier-as-character-writing-the-word has been lost).
It can be presumed that graphemes ability for chemical modification can help tremendously towards its biological applications.
