Image | video 108 : Dendrite formation - effect of G & V on branching; high Co |
Image | video 109 : Dendrite formation - effect of G & V on branching; high Co; real speed |
Image | video 110 : Collumnar growth grain solution |
Image | video 111 : Phase transformation when an isotropic liquid changes to a nematic liquid crystal (magnification 20x, speed 3x). As the temperature decreases the coloured liquid crystalline phase begins to nucleate at various random points across the slide. Darker regions are visible where the director is aligned with either the polariser or the analyser. From TLP: Liquid Crystals |
Image | video 112 : Phase transformation (20x magnification, 4x speed) for isotropic liquid to nematic liquid crystal (on grooved surface). The elongated liquid crystal molecules tend to orientate along the scratches as does nucleation of the liquid crystalline phase, with the liquid crystal sweeping in from the side rather than appearing at random points. From TLP: Liquid Crystals |
Image | video 113 : Phase transformation (20x magnification, 3x speed) for an isotropic liquid to chiral nematic liquid crystal. Although nucleation begins in a similar fashion to the regular nematic, we can see the different regions merge with one another to form the final ‘fingerprint structure’ that is characteristic of chiral nematics with their helical axis parallel to the surface of the slide. From TLP: Liquid Crystals |
Image | video 114 : Part 1 of the phase transformation from an isotropic liquid to a nematic liquid crystal. From TLP: Liquid Crystals |
Image | video 115 : Part 2 of the phase transformation from an isotropic liquid to a nematic liquid crystal. From TLP: Liquid Crystals |
Image | video 116 : The movement of schlieren brushes in a nematic liquid crystal. From TLP: Liquid Crystals |
Image | video 117 : Interactive, rotatable model of an S = 1 disinclination (as in a capillary tube). From TLP: Liquid Crystals |
