“…These theories and a related method by tended to include interface kinetics [16,17]. Steady state models of dendrite growth are based on Ivantsov's solution Miyata et al [40] are not supported by recent experiments on camphene, pivalic acid, and succinonitrile by Rubinstein [18] of the heat transport equation for a paraboloidal, isothermal interface growing at constant velocity into a and Glicksman [41,42] and there is still a debate over whether anisotropy of the interfacial energy provides a uniformly undercooled liquid. For a given undercooling, an infinite number of solutions are given by combinations fundamental physical basis for the dendrite operating state selection [24].…”

“…Dendritic growth is ubiquitous in materials solidification and crystallization. Its complexity characterized as multilevel branching has attracted abroad of interests over the years 3 4 5 6 7 8 9 10 11 12 13 14 . It has been identified that dendrite formation arises from the instabilities when the growth rate is limited by the diffusion rate of ions from the solution to the interface.…”

The electrochemical deposition and dissolution of lead on gold electrodes immersed in an aqueous solution of lead nitrate were studied in situ using a biasing liquid cell by transmission electron microscopy (TEM). We investigate in real time the growth mechanisms of lead dendrites as deposited on the electrodes under an applied potential. TEM images reveal that lead dendrites are developed by the fast protrusion of lead branches in the electrolyte and tip splitting. And, the fast growing tip of the dendritic branch is composed of polycrystalline nanograins and it develops into a single crystalline branch eventually. This study demonstrated unique electrochemical growth of single crystal dendrites through nucleation, aggregation, alignment and attachment of randomly oriented small grains. Additionally, we found the lead concentration in the electrolyte drastically influences the morphology of dendritic formation.

“…Plenty of effort has been devoted to discover the formation mechanism of dendritic structures, and great progress has been made in this field. [19][20][21][22][23][24][25] It is well accepted that dendritic structures are commonly generated under conditions far from equilibrium. [26,27] In such a nonequilibrium system, the formation of dendritic structures is triggered by interface gradient (concentration gradient or temperature gradient and so on).…”

Dendritic structures are widely present in nature, from snowflakes to dendritic cells. However, their formation mechanisms are unclear, which causes long unsolved engineering problems, such as lithium dendrites. Here a strategy to control the growth of dendritic structures by the selective adsorption of ions on crystal facets is reported. Silver particles are synthesized by galvanic replacement reaction and the growth anisotropy of crystals is regulated by changing the concentration of nitrate ions in silver nitrate precursor solution. At a low concentration of nitrate ions, messy branching particles are synthesized while symmetric dendrites are generated at a high concentration of nitrate ions. Molecular dynamics simulation suggests that the selective adsorption of abundant nitrate ions on low-energy facets promotes the prior growth of the high-energy facets, resulting in the symmetric dendritic structures. When the potassium nitrate is changed to sodium nitrate, similar phenomena are obtained, confirming the role of selective adsorption of additives in regulating the growth anisotropy of crystals.
