Webtemperature (e.g. room temperature ), but become very similar at the respective optimum tempera-tures w1 x. Since protein motions are temperature-depend-ent, temperature is a potential probe for the func-tional role of such motions. But if changing the temperature affects all motions at the same time, the value of this probe is less than if it ... IUPAC definition. Glass transition (in polymer science): process in which a polymer melt changes on cooling to a polymer glass or a polymer glass changes on heating to a polymer melt. [8] Phenomena occurring at the glass transition of polymers are still subject to ongoing scientific investigation and … See more 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 … See more Refer to the figure on the bottom right plotting the heat capacity as a function of temperature. In this context, Tg is the temperature … See more Silica, SiO2 Silica (the chemical compound SiO2) has a number of distinct crystalline forms in addition to the quartz structure. Nearly all of the crystalline … See more • Gardner transition • Glass formation 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 … See more As a liquid is supercooled, the difference in entropy between the liquid and solid phase decreases. By extrapolating the heat capacity of the supercooled liquid below its glass transition temperature, it is possible to calculate the temperature at which the difference in … See more Molecular motion in condensed matter can be represented by a Fourier series whose physical interpretation consists of a superposition of longitudinal and transverse waves of atomic displacement with varying directions and wavelengths. In monatomic systems, these … See more
