We report ulsrasonic measurements of the density and bulk modulus of propylene glycol at room temperature and at the temperature of liquid nitrogen up to a pressure of 1.4 GPa. We perform molecular dynamics simulations with two different force fields

The elastic properties of 1-chloroadamantane and 1-Bromoadamantane in order–disorder and order–quasi-order phase transitions at temperatures in the range of 77–305 K and high pressures up to 1.1 GPa are studied by the ultrasonic method. The ela

2-Ethyl-1-hexanol monoalcohol is a well-known molecular glassformer, which for a long time attracts attention of researchers. As in all other monohydroxy alcohols, its dielectric relaxation reveals two distinct relaxation processes attributed to the

We have measured the elastic moduli of liquid and glassy n-propanol and propylene glycol (PG) under pressure by ultrasonic techniques and have recalculated similar characteristics for glycerol from the previous experiment. All three substances form a

As glasses are nonergodic systems, their properties should depend not only on external macroparameters, such as P and T, but also on the time of observation and thermobaric history. In this work, comparative ultrasonic studies of two groups of molecu

We present an ultrasonic and neutron powder diffraction study of crystalline MgSO4·7H2O (synthetic epsomite) and MgSO4·7D2O under pressure up to ~3 GPa near room temperature and up to ~2 GPa at lower temperatures. Both methods provide complementary
