Amorphous silicon material inherently has more tolerance for … WebBecause of the amorphous part, semi-crystalline plastics do have a Tg as well. Let's place a Plasticprop sample made of PA6 in the oven. At 50°C, it feels slightly more flexible than it did at room temperature. But if you take it out of the oven again at 60°C, the difference is bigger. PA6 has exceeded its Tg temperature, which is app. 55°C.
WebCrystalline solids have a very regular pattern, maybe they look something like this. If you imagine the particles, each of these circles being an atom, an ion, or a molecule, while in an amorphous solid, it's a little bit more … Web2 days ago · By modeling the fraction of amorphous and crystalline ice in their isothermal desorption spectra (desorption rate vs time), they found the best curve fit when including an Avrami exponent n = 4. This implies a constant nucleation rate everywhere in the sample and isotropic 3D growth of the nuclei in nanofilms of ASW. To sum up, they found that ...
