High-pressure dilatometer
نویسنده
چکیده
A high-pressure dilatometer capable of measuring volume changes of 2 X loo6 cm3 is described. Fractional volume changes of 1 part in lo4 can be measured over a temperature range of 30-90 “C, and a pressure range of 1 bar (0.1 MPa)-3 kbar (300 MPa). The dilatometer is constructed out of a commercial high-pressure valve and a compact home-built pressure sensor. The system was specially designed to study lipid-water biological systems. Preliminary studies on the lipid dioleoylphosphatidylethanolamine (DOPE) revealed the existence of phases not previously reported for this lipid.

High-resolution thermal expansion measurements under helium-gas pressure.
We report on the realization of a capacitive dilatometer, designed for high-resolution measurements of length changes of a material for temperatures 1.4 K ≤ T ≤ 300 K and hydrostatic pressure P ≤ 250 MPa. Helium ((4)He) is used as a pressure-transmitting medium, ensuring hydrostatic-pressure conditions. Special emphasis has been given to guarantee, to a good approximation, constant-pressure con...
متن کاملDevelopment of a Laser Interferometric Dilatometer for Measurements of Thermal Expansion of Solids in the Temperature Range 300 to 1300 K
A laser interferometric dilatometer has been developed for measuring linear thermal expansion coefficients of reference materials for thermal expansion in the temperature range 300 to 1300 K. The dilatometer is based on an optical heterodyne interferometer capable of measuring length change with an uncertainty of 0.6 nm. Linear thermal expansion coefficients of silicon were measured in the temp...
متن کاملGrowth of Streptococcus faecalis under High Hydrostatic Pressure and High Partial Pressures of Inert Gases
Growth of Streptococcus faecalis in a complex medium was inhibited by xenon, nitrous oxide, argon, and nitrogen at gas pressures of 41 atm or less. The order of inhibitory potency was: xenon and nitrous oxide > argon > nitrogen. Helium appeared to be impotent. Oxygen also inhibited streptococcal growth and it acted synergistically with narcotic gases. Growth was slowed somewhat by 41 atm hydros...
متن کاملSimulation of Dilatometer Tests by Neural Networks
Rock rigidity may be experienced in a wide range depending on several factors, and different methods can be used to consider their load-deformation behaviors. In this context, dilatometer tests (DTs) can be applied to obtain the modulus of elasticity of rock masses; therefore, it is possible to evaluate in-situ stress-strain behavior of rock masses realistically. Nevertheless, the application o...
متن کاملUltra-High Accuracy Measurement of the Coefficient of Thermal Expansion for Ultra-Low Expansion Materials
Microlithographic systems rely on precision alignment and a high-level of dimensional stability to achieve required performance. In critical applications, immunity to thermally induced dimensional changes is achieved by the use of low coefficient of thermal expansion (CTE) materials such as ULE® in components such as reflective optics and machine structures. ULE® has an expansion coefficient (α...
