A Self‐Assembled Planar Chemical Garden in a 3D Solution

Abstract

Addition of calcium chloride solution in sodium phosphate results in the formation of a closed chemobrionic bubble. Subsequent addition of sodium ethylenediaminetetraacetate results in the formation of radially growing fingers that finally yield new types of quasi‐2D chemical gardens that resemble waterlilies and trees.

Characteristic growth of chemical gardens from mixtures of two salts

“…[1][2][3][4][5] For the past four centuries, numerous studies of these fascinating precipitation patterns have been reported. These studies focused on various physicochemical factors [6][7][8][9][10][11][12][13][14][15] including oscillatory growth of hollow microtubes, 12 tube growth with a pinned bubble, 14 and spiral growth of the tube controlled by the application of magnetic force. 15 Recently, chemical gardens have received attention as biomimetic materials due to their ability to form a variety of self-assembled structures, [16][17][18][19][20][21][22][23][24][25][26][27] such as silica-rich biomimetic mineral 20 and self-assembled nanostructures.…”

From Balloon to Crystalline Structure in the Calcium Phosphate Flow-Driven Chemical Garden

“…In this study, we investigate the precipitation of calcium phosphate. Previously, calcium chloride solution was dropped into sodium phosphate solution yielding a planar chemical garden on the solution top or, under microfluidic conditions, their parallel injection resulted in thin calcium phosphate membranes . Hydroxyapatite (Ca 10 (PO 4 ) 6 (OH) 2 , HAP)the most stable form of all calcium phosphate mineralshas gained a lot of interest due to its similarity to the mineral phase of bones , and teeth .…”

Generation of Chemobrionic Jellyfish‐Like Structures That Mechanically Divide and Exhibit Biomimetic “Symbiosis”

“…Here, we focused our investigation on the generation of a new chemobrionic structure that we called chemobrionic bubbles or jellyfish since they resemble the natural jellyfish. The generation of these chemobrionic jellyfish was based on our recently described CaCl 2 ‐phosphate system [17] …”
