C1 - Chaos

DynamicPattern_P_017.jpg
This image depicts experimentally observed chaotic patterns, caused by interaction of chemical waves (Belousov-Zhabotinskii reaction) with convective flow, which is induced by evaporation.

C10 - Wave collision in a pair of spirals

DynamicPattern_P_026.jpg
C10: Colliding spiral waves, as already shown in Image C5, are shown here in 3D perspective. At the colliding fronts one can see a trough caused by a mutual reduction of the excitation front size due to the reaction-diffusion mechanism.

C11 - Coarse grained spiral

DynamicPattern_P_027.jpg
C11:This is a spiral depicted with a specific choice of spatial resolution and colors, thus presenting an artistic version.

C12 - Touch

DynamicPattern_P_028.jpg
C12 Two circular waves touch each other, shown here in 3D.

C13 - Chemical annuli in perspective

DynamicPattern_P_029.jpg
C13 is little bit complicated: starting from a chemical wave pattern, a spatial contraction to small elements is performed. Afterwords, it is converted to 3D with color added.

C14 - Organization by convection in cell-free cytoplasm

DynamicPattern_P_030.jpg
This image depicts dynamics of pattern formation reaching a higher level of complexity as a convective flow joins diffusion as a transport mechanism. If, e. g., surface forces, as they are caused by gradients in concentration and/ or temperature…

C15 - Rosette in 2D (cytoplasm)

DynamicPattern_P_031.jpg
C15, A tiny drop of phoshate falls on a layer of cell-free cytoplasm from yeast. It follows a reaction in a star-like fashion forming a rosette.

C16 - Compartmentation by surface forces (cytoplasm)

DynamicPattern_P_032.jpg
C16 ,The procedure to create this pattern is the same as in C15, but the depth of the cytoplasmic layer is larger. The interplay of reaction and diffusion with addition of convectio driven by surface tension produces a complex pattern consisting of…

C17 - Boundaries of convective flow across waves (BZ)

DynamicPattern_P_033.jpg
The dynamics of pattern formation reaches a higher level of complexity as soon as convective flow joins diffusion as a transport mechanism. If, e. g., surface forces, as they are caused by gradients in concentration and/ or temperature (mostly…

C18 - Reactive excitation by convection (BZ)

DynamicPattern_P_034.jpg
The dynamics of pattern formation reaches a higher level of complexity as soon as convective flow joins diffusion as a transport mechanism. If, e. g., surface forces, as they are caused by gradients in concentration and/ or temperature (mostly…
