Dilatometry at low temperatures
Review of Scientific Instruments, 1982A dilatometer has been constructed for the routine measurement of thermal expansion coefficients in the temperature range of 0.1–10 K. Using a SQUID detector, the dilatometer provides a resolution of 2×10−4 Å. As a test of this apparatus, the linear thermal expansion coefficient of high-purity copper has been measured between 0.2 and 9 K.

Dilatometry under high pressure
High Pressure Research, 2000Abstract In order to measure anisotropic compressibilities and thermal expansion of cubic, tetragonal or orthorhombic single crystals under pressure we have miniaturized a high resolution capacitive dilatometer and integrated this device in a high pressure cell within a cryostat which allows a temperature variation from 10 K to 320 K.

Conversion factors in dilatometry
Polymer, 1967Abstract In dilatometric determinations of the extent of polymerization reactions the difference between the partial specific volumes of the reactants and the products determines the volume contraction. The partial specific volumes cannot be assumed to be equal to the specific volumes of the respective pure compounds.

Journal of Analytical and Applied Pyrolysis, 1992
Dilatometry of Japanese cedar wood treated with sodium borate, ammonium bromide and sodium chloride was carried out according to the procedure described previously. The sodium borate-treated wood first underwent shrinkage due to bond formation in hemicelluloses, such as cross-linking and grafting, then elongation due to the chain scission of cellulose,

High pressure dilatometry on polybutene-1
Colloid and Polymer Science, 1983High pressure dilatometry is used to study the melting processes and the melt of isotactic polybutene-1. Evaluating a great number of isobaricV(T)-curves determined in the range of a few hundred bar the pressure dependence of the melting temperature is accurately determined for modifications I and II.

Dilatometry, a neglected method in immunological studies
Journal of Immunological Methods, 1975Dilatometry has become a useful method for the study of proteins owing to its simplicity and accuracy. However, it has seldom been used in the study of immunoglobulins. Therefore possible applications of the method for that study are being discussed.

Dilatometry and calorimetry of saturated phosphatidylethanolamine dispersions
Biochemistry, 1981The specific volumes of a series of saturated phosphatidylethanolamine dispersions with 12, 14, and 16 carbon atoms per chain have been measured in the region of the chain melting transition, Tm. The change in specific volume at Tm for the 12 and 14 carbon compounds are 0.0160 and 0.0204 mL/g, respectively.

A Radiographic Method of Dilatometry
Review of Scientific Instruments, 1951A method of dilatometry using x-ray illumination has been developed and applied to measurements of compressibility. Metal samples, 10 in. long and 316 in. in diameter, are subjected to pressures up to 10,000 atmospheres. Observations of the length of the compressed sample are made by causing x-rays to cast a shadow on a photographic plate.

High temperature dilatometry of Ti-6242
Scripta Metallurgica, 1987Abstract Both normal heat-treatments and hot compression of Ti-6242 produce a rich variety of non-equilibrium microstructures. It was attempted to characterize subsequent phase transformations by monitoring dilatation during linear heating. The results seem anomalous when compared to simple transformation and solute effects but may be related to ...

Dilatometry of Ni3Al powder disordered by ball-milling
Intermetallics, 1995Abstract The microstructure and reordering behaviour of Ni3AI-base alloy has been studied following completion of a broader research on ordering kinetics of some intermetallic compounds. A disordered structure has been obtained in powder samples with high energy ball-milling.
