Alchemical Symbols is a Unicode block containing symbols for chemicals and substances used in ancient and medieval alchemy texts. Many of the symbols are duplicates or redundant with previous characters.
A superscript small-cap W may be distinct from a superscript lowercase w in italic typeface, as in this phonetic notation. Consolidated, the Unicode standard contains superscript and subscript versions of a subset of Latin, Greek and Cyrillic letters. Here they are arranged in alphabetical order for comparison (or for copy and paste convenience).
Superscripts and subscripts of arbitrary height can be done with the \raisebox{<dimen>}{<text>} command: the first argument is the amount to raise, and the second is the text; a negative first argument will lower the text. In this case the text is not resized automatically, so a sizing command can be included, e.g. go\raisebox{1ex}{\large home}.
the fine-structure constant in physics [2] [3] the angle of attack of an aircraft; an alpha particle (He 2+) angular acceleration in physics [4] the linear thermal expansion coefficient; the thermal diffusivity [5] In organic chemistry the α-carbon is the backbone carbon next to the carbonyl carbon, most often for amino acids; right ascension ...
The standard state of a material (pure substance, mixture or solution) is a reference point used to calculate its properties under different conditions.A degree sign (°) or a superscript Plimsoll symbol (⦵) is used to designate a thermodynamic quantity in the standard state, such as change in enthalpy (ΔH°), change in entropy (ΔS°), or change in Gibbs free energy (ΔG°).
Open {} and copy the relevant (simple, medium, full) box desired, and paste into a text editor; Open the relevant reference (e.g. MSDS, Merck Index, CRC Handbook, etc.) and input the data into the template; Copy the filled-out template into the relevant Wikipedia article.
The triple bar character in Unicode is code point U+2261 ≡ IDENTICAL TO (≡, ≡). [1] The closely related code point U+2262 ≢ NOT IDENTICAL TO (≢, ≢) is the same symbol with a slash through it, indicating the negation of its mathematical meaning.
