High-resolution, high-sensitive ac calorimeter.
(1992)
A high-resoln., high-sensitivity, automated ac calorimeter capable of heat capacity measurements
of very small samples (m < 20 mg) with a temp. resoln. of a few mK in the ac mode is described.
This calorimeter also can be ...
Thermal conductivity of (Er1-xYx)(2)Ti2O7 pyrochlore oxide solid solutions
(2012-08)
The thermal conductivities of pyrochlore oxide solid solutions of general formula
(Er1-xYx)(2)Ti2O7 with 0 <= x <= 1 have been determined for high-quality single crystals
aligned along the [110] direction, over the ...
Thermal conductivities of a clathrate with and without guest molecules.
(1992)
The thermal conductivities of Dianin's compd. [4-(p-hydroxyphenyl)-2,2,4-trimethylchroman] and
its ethanol adduct in the temp. range 20-250 K are reported. This clathrate has the same stable
structure both with and without ...
Heat capacity, lattice dynamics, and thermodynamic stability of the negative thermal expansion material HfMo2O8
(2007-06)
We explore the lattice dynamics of the negative thermal expansion material, cubic HfMo2O8,
through analysis of its heat capacity (measured from 0.5 to 300 K) and its room-temperature Raman
spectrum. Its heat capacity is ...
A study of phase transitions in cadmium perchlorate hexahydrate (Cd(ClO4)2.6H2O) by adiabatic calorimetry and infrared spectroscopy.
(1985)
A calorimetric study of Cd(ClO4)2.6H2O from 20 to 345 K shows 3 phase transformations, at 124.8,
238.45, and 271.62 K. IR spectra indicate that the low-temp. structure (below 124.8 K) contains 1
type of [Cd(OH2)6]2+, of ...
A calorimetric investigation of the low-temperature phase transition in sodium hydroxide-d.
(1986)
The heat capacity of NaOD from 20 to 350 K is reported. An anomaly centered at 153.2 ± 0.1 K (?H
= 131.1 ± 0.7 J/mol, ?S = 0.864 ± 0.005 J/K.mol) corresponds to the onset of a low-temp.
antiferroelec. phase. This ...
Investigation of factors affecting crystallization of cyclopentane clathrate hydrate
(2008-11)
We report the results of systematic investigations of the influence of thermal history and other
factors on crystallization of a model clathrate hydrate (cyclopentane hydrate) studied as
water-in-oil and oil-in-water ...
A thermodynamic investigation of dynamical disorder in phase II of CBr4.
(1995)
CBr4 is an archetypal example of a pseudospherical mol. that can form an orientationally
disordered phase (phase I, 320 K < T < 365 K). At lower temps., phase II is the stable phase;
although it must be more ordered than ...
Phase transitions in metal perchlorate hydrates: the supposed hydrate-to-pseudohydrate transformations.
(1984)
A polemic. The hydrate-to-pseudohydrate transformations in metal perchlorate hydrates reported
by M. B. Patel and H. D. Brist (ibid. 1983, 79, 4489) and Solid State Commun. (48, 139 (1983)) as
well as the suggested ...
Temperature dependence of thermal conductivity enhancement in single-walled carbon nanotube/polystyrene composites
(2010-02)
The thermal conductivity of single-walled carbon nanotube (SWCNT)/polystyrene composites,
prepared by a method known to produce a uniform distribution of SWCNT bundles on the micrometer
length scale, was measured in the ...
