An Experimental Assessment of Continuum Models of Dendritic Growthions, such as the dependence of the growth state on crystalline anisotropy, have not been convincingly demonstrated, and the models may not be appropriate in all cases, for example when kinetic effects are important. On the other hand, the continuum models provide an internally consistent explanatio

Dendritic Solidification of Rare Gaseso solution systems are: short relaxation times and good repro-ducibility. The parameters characterizing the shapes of the dendrite tips have been determined. The volume solidification rate of dendrites increases with increasing supercooling of the melt, thus the stability-“constant” decreases with i

Light Scattering Experiments during the Freezing and Melting Transitioniscussion: 1.) Light is scattered by continuous fluctuations in a mesophase layer; 2.) Light is scatterd by gas bubbles in front of the growing crystal. In this paper it is shown that the bubbles model is not compatible with the experiment. The model with continuous fluctuations is compatible with t

Sidebranching of Xenon Dendritesrst measurements of the spatial evolution of the sidebranches have been performed. The maximal amplitude w of the sidebranches has been measured as a function of their position l. at the fin. It has been found w ~ l.1.72 independent of the supercooling. No decrease of the amplitude for large l. has

Dendrites Growing in the Presence of an External Flow: The Cases of PVA and NH4Brs. Theoretical predictions. for the values of growth constant, C = 4 ρ.V/Dd. are now available (here ρ, V are the tip radius and the growth velocity of the dendrite, and D, d. are the diffusion constant and the capillary length). Until now, only a few measurements of the growth constant have been do

Dendritic Growth of NH4Cl: Nucleation, Boundary Conditions, Periodic and Aperiodic Morphologiespes that nature creates. Even a single material can show different morphologies when it grows in various environments. Were the crystal in thermodynamic equilibrium its shape would be uniquely defined (up to a scale factor) at a given temperature, in a way which is in principle completely understood

Anisotropic Ordered Phases in Langmuir Monolayersnsitions between phases of increasing surface density: gaseous, liquid (expanded or condensed) and solid.. By using fluorescent molecules, it is now possible to visualize the different phases of these films., and to make a quantitative analysis of their growth and equilibrium properties. In this pap

A Numerical Analysis of Dendritic and Cellular Growth of a Pure Material Investigating the Transitioates and dendrites having axial symmetry have been treated. For a finite surface energy, discrete solutions rather than a continuum of solutions were obtained for steady state dendritic growth at a fixed undercooling. The problem was considered in the limit of a zero specific heat so that the result
