picture info	Vicinal (chemistry) In chemistry the descriptor vicinal (from Latin ''vicinus'' = neighbor), abbreviated ''vic'', describes any two functional groups bonded to two adjacent carbon atoms (i.e., in a 1,2-relationship). Relation of atoms in a molecule For example, the molecule 2,3-dibromobutane carries two vicinal bromine atoms and 1,3-dibromobutane does not. Mostly, the use of the term vicinal is restricted to two ''identical'' functional groups. Likewise in a ''gem-''dibromide the prefix ''gem'', an abbreviation of geminal, signals that both bromine atoms are bonded to the ''same'' atom (i.e., in a 1,1-relationship). For example, 1,1-dibromobutane is geminal. While comparatively less common, the term hominal has been suggested as a descriptor for groups in a 1,3-relationship. Like other such descriptors as syn, anti, exo or endo, the description ''vicinal'' helps explain how different parts of a molecule are related to each other either structurally or spatially. The vicinal adjective is sometim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Vicinal (logology) A vicinal is a logological term for a word where all its letters have "alphabetic An alphabet is a standardized set of basic written graphemes (called letters) that represent the phonemes of certain spoken languages. Not all writing systems represent language in this way; in a syllabary, each character represents a syllab ... neighbors". For instance, if a word has an "O" in it, to be a vicinal it must also have an "N" and/or a "P". If none of the letters have alphabetic neighbors, it is known as a nonvicinal.

picture info	Vicinal Tramway The National Company of Light Railways ( nl, Nationale Maatschappij Van Buurtspoorwegen, abbreviated as NMVB; french: Société Nationale des Chemins de fer Vicinaux, abbreviated as SNCV) was a state-owned transportation provider which comprised a system of narrow-gauge tramways or local railways in Belgium, which covered the whole country, including the countryside, and had a greater route length than the mainline railway system. They were and included electrified city lines and rural lines using steam locomotives and diesel railcars; half the system was electrified. The company gradually switched to buses and dismantled the tram tracks. Only the coastal line, the Charleroi metro, and the short line to the caves at Han-sur-Lesse are still in commercial use; four museums hold significant collections of rolling stock, including the museum at Schepdaal and the ASVi museum in Thuin. The longest () and oldest (40 years) tourist tramway is the '' Tramway Touristique de l'Aisne'' ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Thin Film A thin film is a layer of material ranging from fractions of a nanometer (monolayer) to several micrometers in thickness. The controlled synthesis of materials as thin films (a process referred to as deposition) is a fundamental step in many applications. A familiar example is the household mirror, which typically has a thin metal coating on the back of a sheet of glass to form a reflective interface. The process of silvering was once commonly used to produce mirrors, while more recently the metal layer is deposited using techniques such as sputtering. Advances in thin film deposition techniques during the 20th century have enabled a wide range of technological breakthroughs in areas such as magnetic recording media, electronic semiconductor devices, integrated passive devices, LEDs, optical coatings (such as antireflective coatings), hard coatings on cutting tools, and for both energy generation (e.g. thin-film solar cells) and storage ( thin-film batteries). It is also being ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Surface Normal In geometry, a normal is an object such as a line, ray, or vector that is perpendicular to a given object. For example, the normal line to a plane curve at a given point is the (infinite) line perpendicular to the tangent line to the curve at the point. A normal vector may have length one (a unit vector) or its length may represent the curvature of the object (a ''curvature vector''); its algebraic sign may indicate sides (interior or exterior). In three dimensions, a surface normal, or simply normal, to a surface at point P is a vector perpendicular to the tangent plane of the surface at P. The word "normal" is also used as an adjective: a line ''normal'' to a plane, the ''normal'' component of a force, the normal vector, etc. The concept of normality generalizes to orthogonality (right angles). The concept has been generalized to differentiable manifolds of arbitrary dimension embedded in a Euclidean space. The normal vector space or normal space of a manifold at point P ...
