Non Technical Summary Spherulite formation is an example of selfassembly, where building blocks spontaneously arrange themselves into larger, more complex structures These structures determine the material's functionality in both foods and biological systems Understanding of spherulite formation is limitedThis is eventually overgrown, including both originally separate structures (see pink arrows in Fig 2E)Spherulite (plural spherulites) a minute spherical crystalline body having a radiated structure, observed in some vitreous volcanic rocks, as obsidian and pearlstone;

Also, you should definitely try seeding if you think nucleation is the problem Take one of your drops with lots of crystals (spherulites) and vortex it vigorously to break the crystals (called a'In the absence of salt, the spherulite kinetic assay suggests the presence of spherulites from ~ 40 to 45 min' 'Under the polarized light microscope, addition of a full waveplate to the optical setup showed that spherulites grown in the absence or presence of salt contain radially oriented amyloid fibrils'Given the relative rarity of spherulite formation in nonglass forming metallic melts this article focuses solely on the spherulite structures Such spherulites are observed to form for cooling rates in the range 700–4600 K s −1 , corresponding to droplets sizes of >850 μm, 850–500 μm, 500–300 μm and 300–212 μm

The arms of the black cross correspond to those fibers that are extinguished The aggregate is too finegrained to directly determine what minerals it is composed of using visible light microscopySpherulite, spherical body generally occurring in glassy rocks, especially silicarich rhyolites Spherulites frequently have a radiating structure that results from an intergrowth of quartz and orthoclaseEach spherulite exhibits a CoG from which radial lines emerge (see pink arrows in Fig 2D) There is a disruption zone between adjacent spherulites (see blue arrows in Fig 2E);

Homogeneous nucleation of spherulites at the melting point is a highly unfavorable process because the energy barrier of nucleation is infinitely high and the critical nucleus size is infinitely large The degree of super cooling defines the critical cluster size and energy of spontaneous crystallization;Many structural materials (metal alloys, polymers, minerals, etc) are formed by quenching liquids into crystalline solids This highly nonequilibrium process often leads to polycrystalline growth patterns that are broadly termed "spherulites" because of their largescale average spherical shape DeDefinition of spherulite in the Definitionsnet dictionary Meaning of spherulite What does spherulite mean?
