Below T g … WebOct 25, 2011 · All SD trehalose samples showed an amorphous glassy-to-rubbery phase transition, T g, (i.e., characteristic baseline shift) at ∼50°C, followed by an exothermic disorder-to-order phase transition near 95°C which suggests crystallization at T c from the amorphous rubbery state. A small endothermic order-to-disorder peak was observed in …
WebThis produces the glassy state, which is hard, rigid, and brittle. When the temperature rises above T g, the entangled chains can move (small portions of the spaghetti noodles can move around). This produces a rubbery state, when an amorphous polymer is … The glass–liquid transition, or glass transition, is the gradual and reversible transition in amorphous materials (or in amorphous regions within semicrystalline materials) from a hard and relatively brittle "glassy" state into a viscous or rubbery state as the temperature is increased. An amorphous solid that exhibits a … See more The glass transition of a liquid to a solid-like state may occur with either cooling or compression. The transition comprises a smooth increase in the viscosity of a material by as much as 17 orders of magnitude within … See more As a liquid is supercooled, the difference in entropy between the liquid and solid phase decreases.
