Effect of hydrostatic pressure on the two (I – monoclinic and II – orthorhombic) polymorphs of paracetamol was studied by X-ray diffraction in the diamond anvil cell at pressures up to 4.5 GPa (for the monoclinic form) and up to 5.5 GPa (for the

Interesting results were obtained in the initial investigation of the nucleation behavior of supersaturated sulfur vapor up to temperatures above the λ transition. This is a second-order phase transition in liquid sulfur characterized by a change in

Variation of the unit cell parameters of paracetamol and phenacetin as a function of hydrostatic pressure was studied by X-ray diffractometry in diamond anvils. At elevated pressure (4 GPa), the crystal structures undergo anisotropic distortion. The

Calculations are carried out to solve the thus far puzzling problem of the long‐time trends in the photoinduced condensation of supersaturated vapors observed in thermal diffusion cloud chambers. These trends are the long‐time delay of the conden
