The object of the contract includes the supply of a measuring set for determining the transition temperature of high-temperature superconductors and a set for the presentation of the meissner-ochsenfeld phenomenon in high-temperature superconductors.
Then, using *Bayesian optimization, the researchers made repeated efforts to predict and verify a polymer with the highest glass transition temperature out of the remaining 407 sets of data.
Glass transition temperature ([T.sub.g]) studies were conducted on polished, annealed samples.
A parametric study was undertaken to investigate the influence of phase transition temperature of PCM and thermal conductivities of PCM and the thermal control effect of the double PCM layers compared to other two cases.
The investigators found that cheese properties, including elasticity, free oil and transition temperature, influence the color uniformity of cheeses.
For most practical applications the phase transition temperature [T.sub.c] needs to be in the vicinity of room temperature (~25[degrees]C) and the [T.sub.c] may be assumed to be correlated with the optical band gap [E.sub.2].
Te aim of the present work is to characterize glass thermal expansion coefficient, and their transition temperatures. There is a strong dependence between the glass transition temperature, [T.sub.g], thermal expansion coefficient and the kind of the modifier [17].
Phase transition temperature of AlOOH [right arrow] [gamma]-[Al.sub.2][O.sub.3] was about 773 K.
First, the surface temperature of the hinge must exceed the glass transition temperature of the material, which is the point at which the material begins to soften.
Abstract Relaxation of surface defects shows that the surface of a crosslinked epoxy system, under normal laboratory conditions, apparently has a softening transition temperature that is approximately 20[degrees]C lower than calorimetric measures of [T.sub.g] in the bulk.
This composition contains a hydrophobic agent characterized as having a melting point or glass transition temperature of less than 100[degrees]C; a fluoropolymer; and an effective amount of a zeta potential modifier.
