Glass Transition Temperature (Tg )
, 2016 At the macroscopic scale, the glass transition temperature, Tg, represents the temperature above which a material changes from a stiff glass into a viscous fluid or a rubbery material. Besides polymers, which are the most common materials with a glass transition temperature, also various amorphous solids, organic liquids, alloys, or inorganic glasses ...

Glass Transition Temperature Depression
, 2016 Glass transition temperature depression is the phenomenon which describes the reduction of the glass transition temperature by external factors, usually by the presence of solvent molecules or of other additives in the polymer matrix. Such additives have the capacity to enhance the mobility of the polymer chains, thus enabling long range motions at ...

“Glass transition” in peptides: Temperature and pressure effects
The Journal of Chemical Physics, 2005 We report on the origin of the liquid-to-glass transition in a series of oligopeptides of γ-benzyl-L-glutamate up to the polymer (PBLG), and in Poly-Z-L-lysine (PZLL) and Polyglycine (PGly) using dielectric spectroscopy as a function of temperature and pressure.

Complexity of confined water vitrification and its glass transition temperature. [PDF]
Proc Natl Acad Sci U S AThe ability of vitrification when crossing the glass transition temperature (T(g)) of confined and bulk water is crucial for myriad phenomena in diverse fields, ranging from the cryopreservation of organs and food to the development of cryoenzymatic ...

Second-order Phase Transition Behavior behind Polymer Glass Transition [PDF]
, 2022 Glass transition has similarity to the second-order phase transition in temperature dependent changes in entropy, non-Arrhenius viscosity, and heat capacity of glass forming materials. However, it has primarily been considered to be not phase transition.

Molecular Signatures of the Glass Transition in Polymers [PDF]
, 2022 The glass transition temperature (Tg) is one of the most fundamental properties of polymers. Tg is predicted as a sudden change in a “macroscopic” quantity (e.g. compressibility).

Polymer Relaxation Time Enhancement at Temperatures above Glass Transition Temperatures Predicted by Idealized Mode-Coupling Theory [PDF]
, 2022 The mode-coupling theory of glass transition predicts the relaxation time divergence of glass-forming materials at the crossover temperature, which is approximately 1.2 times the calorimetric glass transition temperature. However, this divergence has not

Temperature-dependent thermal expansivities of silicate melts: The system anorthite-diopside [PDF]
, 1992 The temperature-dependent thermal expansivities of melts along the join anorthite-diopside have been determined on glassy and liquid samples using a combination of calorimetry, dilatometry, and Pt double bob Archimedean densitometry.

Study on the temperature dependence of the bulk modulus of polyisoprene by molecular dynamics simulations [PDF]
, 2008 The temperature dependence of the bulk modulus of polyisoprene has been studied using molecular dynamics simulations. Virtual polyisoprenes have been submitted to volume contractions above and below the glass transition. Bulk modulus has been observed to
