Dendrite (crystal) - Wikipedia
A crystal dendrite is a crystal that develops with a typical multi-branching form, resembling a fractal. The name comes from the Ancient Greek word δένδρον (déndron), which means "tree" [citation needed], since the crystal's structure resembles that of a tree.
Dendrite (metal) - Wikipedia
A dendrite in metallurgy is a characteristic tree-like structure of crystals growing as molten metal solidifies, the shape produced by faster growth along energetically favourable crystallographic directions. This dendritic growth has large consequences in regard to material properties.
Dendritic crystal growth in pure materials - ScienceDirect
2004年3月31日 · These investigators considered dendritic crystal growth of a pure substance and identified three coupled kinetic effects: (1) transport (conduction) of latent heat; (2) molecular attachment at the crystal–melt interface; and (3) creation of interfacial area. Temkin, Bolling, and Tiller associated each of these kinetic effects with the ...
Dendritic Crystal - an overview | ScienceDirect Topics
A dendritic crystal is defined as a treelike crystal structure with multiple levels of branching, including primary, secondary, and tertiary branches. These crystals can develop in one plane or three-dimensional forms, and when the spaces between branches are filled with calcite precipitation, they are known as "filled-in dendrites".
Dendritic Crystal and Minerals - Geology In
Dendritic crystal habits in minerals are notable for their tree-like, branching patterns, which form under specific environmental conditions. Common minerals exhibiting these patterns include manganese oxides, native copper, silver, gold, iron oxides, and uranium oxides.

Engineering crystals of dendritic molecules - PNAS
2009年7月7日 · In this article, we report the first systematic structural study of flexible branched molecules lacking directive functionalities. This study relies on the single-crystal X-ray analyses of 13 structures of increasing branched complexity and is accompanied by theoretical calculations.
Dendrite - Prehistoricoregon
A crystal dendrite is a crystal that develops with a typical multi-branching tree-like form. Dendritic crystal growth is very common and illustrated by snowflake formation and frost patterns on a window. Dendritic crystallization forms a natural fractal pattern.
