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 ...

Why is there no low-temperature phase transition in NaOH?
(1999-02)
Although NaOH and NaOD exhibit parallel polymorphism at high temperatures, NaOD exhibits a
low-temperature phase transition to a hydrogen-bonded antiferroelectric phase and no comparable
transition has been found in NaOH. ...

Apparatus for dynamical thermal measurements of low-thermal diffusivity particulate materials at subambient temperatures
(1998-12)
Apparatus for measurement of thermal diffusivity of particulate matter in the temperature range
of 10-300 K is described. The basis of the measurement is modulated radial heat flow into a
cylindrical sample, with a relatively ...
Thermal and Diffraction Studies of Phase-Transitions in the Incommensurate Compound [P(Ch3)(4)]2CuCl4

Calorimetric and x-ray-diffraction studies of the commensurate
Structure and Disorder of Phosphates in Ag2o-Agi-P2o5 Glasses
(1993-06)
We directly probe the microstructure of the different phosphates in several glasses in the
Ag2O-AgI-P2O5 system, by means of variable angle correlation NMR spectroscopy. This two-dimensional
experiment separates the ...
Heat capacity of gadolinium near the Curie temperature.
(1993)
High-resoln. ac calorimetric data near the Curie point are reported for several single crystals
of gadolinium. The crit. temp. and the shape of the heat-capacity curve near Tc both depend on the
sample-prepn. procedure, ...
