The glass transition temperatures of sugar mixtures
Carbohydrate Research, 2006We measured the glass transition temperatures of mono-, di-, and trisaccharide mixtures using differential scanning calorimeter (DSC) and analyzed these temperatures using the Gordon-Taylor equation. We found that the glass transition temperatures of monosaccharide-monosaccharide and disaccharide-disaccharide mixtures could be described by the ...

Glass Transition Temperature and Other Transitions
1993The glass transition temperature (Tg) is defined as the temperature at which a material loses its glasslike, more rigid properties and becomes rubbery and more flexible in nature. Practical definitions of Tg differ considerably among different measurement methods; therefore, specification of Tg requires indication of the method used.

Fracture Toughness in the Transition Temperature Region
Advanced Materials Research, 2018The steels fracture toughness was measured at two different temperature T= - 60°C and T = -90°C, at v=0.02 mm/min and v=0.5mm/min. The following steels: CrMoV, 20MnMoNi55, A533B and A508 were tested with three different sizes of CT specimens 50 and 100 and 200.

Model with roughening transition at low temperatures
Physical Review B, 1986We note that for the Ising model on a body-centered-cubic lattice the temperature ${T}_{R}(J)$ of the roughening transition approaches zero when the second-neighbor coupling $J$ vanishes; the interface (100) between regions of opposite magnetization is, at low temperatures, rigid for $J$ positive and becomes rough for $J$ negative.

The Superconducting Transition Temperature
1986After the presentation of a brief survey of the principal formulae of weak- coupling and strong-coupling superconductivity, followed by discussion of the priorities under which the transition temperature is governed by atomic, band-electronic, and lattice-dynamical effects, the compositional systematics of T c in amorphous and crystalline transition ...

Liposome filtration. Dependence on transition temperature
Biochimica et Biophysica Acta (BBA) - Biomembranes, 1980Liposomes formed by vortexing and passed through polycarbonate surface retention membranes showed appreciable differences in filtration behavior depending on the temperature of filtration relation relative to the liposome gel-liquid crystal transition temperature.

Transition temperatures in ferroelectrics
Ferroelectrics, 1995Abstract Two recent series of studies exemplified by Tokunaga, J. Phys. Soc. Jpn., 57, 4275 (1988); Venevtsev et al., Ferroelectrics, 130, 245 (1992) have made interesting proposals: 1) that Ferroelectrics do not have Curie temperatures much below 100 K (Tokunaga); and 2) that ferroelectrics have transition temperatures that are “quantized” in units of

Proximity-induced superconducting transition temperature
Physical Review B, 1989We have calculated the proximity-induced superconducting transition temperature for a thin weak-coupling normal metal in contact with an infinitely thick strong-coupling superconductor. The model considered is that of aluminum in perfect contact with superconducting lead, where both metals are clean.

Phase-transition temperature in finite systems
Physical Review B, 1993Pathria's approach has been used to deal with the properties of the finite cubic system of [sup 4]He under constant pressure. The analytic expressions for the total number of particles [ital N] and the total pressure [ital p] near the critical point are obtained for mixture, antiperiodic, Neumann, and periodic boundary conditions. Influences of various

A Thermodynamical Criterion for the Glass-Transition Temperature
Transactions of the Society of Rheology, 1977A study, based upon the Gibbs free energy, is made of the thermodynamical behaviour of dissipative and memory-dependent materials. The creep-function mechanical properties involved are generalizations of the usual volumetric compressibility, the coefficient of thermal expansion, and the specific heat at constant pressure.
