    Notes: [Auszug] The temperature dependence almost universally observed at T〉100K with crystalline, non-metallic solids is l(T)?T-1. This negative slope agrees with the theory of phonon-phonon scattering by the simplest umklapp mechanism. Positive slopes of l (T) are encountered for non-crystalline materials in the ...

    Notes: [Auszug] Most of the rock samples used in this study are high-grade metamorphics from the Lewisian of NW Scotland, which have a very low porosity ( 〈 1%). These were cored, cut and ground into cylinders of diameter 24.5 mm and length 10-20 mm, and saturated with a 0.5 or 0.05 M sodium chloride solution. ...

    Keywords: bulk modulus ; heat capacity ; high-pressure poly(methyl methacrylate) ; thermal conductivity ; transient hot-wire method

    Topics: Physics
    Notes: Abstract The thermal conductivity and heat capacity per unit volume of poly(methyl methacrylate) (25 and 350 kg · mol− in molecular weight) have been measured in the temperature range 155–358 K at pressures up to 2 GPa using the transient hot-wire method. The bulk modulus has been measured up to 1.0 GPa at 294 K and yielded a constant valueg = 3.4 ± 0.3 for the Bridgman parameter. No dependence on molecular weight could be detected in the properties we measured.

    Thermal conductivity and heat capacity of solid silver bromide (AgBr) under pressure (1981)
    Springer
    International journal of thermophysics 2 (1981), S. 331-340 
    Details
    ISSN: 1572-9567
    Keywords: heat capacity ; high pressure ; silver bromide (AgBr) ; silver chloride (AgCl) ; thermal conductivity
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract The thermal conductivity, λ, and the heat capacity per unit volume, ρc p , have been measured for solid silver bromide (AgBr) using the transient hot-wire method. Measurements were made at temperatures in the range 100–400 K and at pressures up to 2 GPa. ρc p was found to be independent of temperature and pressure over these ranges. λ of AgBr was found to be similar to that of AgCl, which was measured previously. For AgBr, only acoustic phonons needed to be taken into account up to 340 K, but optic phonons probably carried some heat at higher temperatures. The Leibfried-Schlömann (LS) formula could describe the ratio λ(AgCl)/λ(AgBr), but not the ratio λ(1 GPa)/λ(0) for either substance. An empirical modification of the LS formula could describe the latter ratios but not the former. Further theoretical developments are required for understanding of λ(P) for even such relatively simple substances as AgCl and AgBr.

    Phase behavior and thermal conductivity of urea at pressures up to 1 GPa and at temperatures in the range 50–370 K (1994)
    Springer
    International journal of thermophysics 15 (1994), S. 513-524 
    Details
    ISSN: 1572-9567
    Keywords: high pressure ; phase behavior ; thermal conductivity urea
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract The thermal conductivity of the solid phases I and III of urea was measured at temperatures in the range 50–370 K for pressures up to 1 GPa. Phase III, previously detected only at pressures above 0.5 GPa, was observed here at low pressures ( 〈0.07 GPa) below about 230 K. Extrapolation of the I–III phase line indicates that phase III might be obtained at 218 K at atmospheric pressure and, consequently, that urea might exhibit two solid phases at atmospheric pressure. The temperature dependence of the thermal conductivity of both phase I and phase III could be described by the Debye model for thermal conductivity assuming phonon scattering by three phonon umklapp processes only. Despite a volume decrease at the I → III transition, the thermal conductivity decreased by about 20%. Normally, thermal conductivity increases at a phase transition at which volume decreases. This rather unusual behavior of urea might be due to an increase in the nearest-neighbor distance at the I → III transition.

    Glass transition in viscous crude oils under pressure (1994)
    Springer
    International journal of thermophysics 15 (1994), S. 165-176 
    Details
    ISSN: 1572-9567
    Keywords: bulk modulus ; crude oil ; glass transition ; heat capacity ; high pressure ; thermal conductivity
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract The transitions to the glassy state in viscous crude oils have been investigated at high pressures by the transient hot-wire method, by differential scanning calorimetry, and by equation-of-state measurements. The range of pressures investigated was up to 1.2 GPa in the temperature interval 150–370 K. The glass transition in crude oils is a common phenomenon and occurs due to the viscosity increase on decreasing the temperature or increasing thepressure. The actual transition coordinates depend not only on physical properties but also on the characteristic experimental time.

    Specific heat capacity of solids under pressure from measurements of (∂T/∂P)s (1985)
    Springer
    International journal of thermophysics 6 (1985), S. 101-105

    ISSN: 1572-9567
    Keywords: adiabatic compression ; calculational procedure ; high pressure ; specific heat capacity
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract A procedure is described for calculating specific heat capacity under pressure, c p (T, P), from data for c p (T, 0) and adiabatic (∂T/∂P) s. The main advantage is that (∂T/∂P)s can be readily measured under high-pressure conditions.
