The article discusses further research of the new high-pressure phase in triolein and in triolein mixed with methyl alcohol. The transformation from the initial isotropic state of liquid to the high-pressure phase in case of the mixture of triolein

We present the results of the experimental study of transmitted and scattered light in oleic acid under carefully selected rates of pressure changes automatically exerted at different ambient temperatures. When the temperature of the investigated sam

In this study, we show that in the case of oleic acid, the transition to the high-pressure phase, strong scattering of light phase is observed. Before this state is reached, the investigated liquid goes into a stable intermediate state at lower press

When benzanthrone (Bt), a weak electron acceptor, is doped into poly(N-vinylcarbazole) (PVCz) solution or film, an excited carbazole chromophore (D*) interacts with Bt to form a new exciplex state, which gives a broad fluorescence band (λ max = 440

It is known, that pressure has a specific effect on the permittivity of some liquids in which all molecules have an unsaturated double bond CC. Castor oil, one of these liquids, exhibits a strong increase of scattering of radiation in the visible

Castor oil shows non-conventional physical and chemical behaviour when submitted to pressure. This paper gives a brief presentation of the specific physical properties of castor oil under pressure up to 1.0 GPa. The changes of permittivity, dielectri

Liquid oleic acid and castor oil (at temperature T = 20°C) exhibit a strong scattering in the case when pressures above 0.21 and 0.36 GPa are applied, respectively. The transmitted and scattered light have been viewed at an angle θ = 0° and at an

In our earlier works several fatty liquids (edible oils and unsaturated fatty acids) which exhibit existence of a new phase induced by high pressure were presented. Conclusion of those experiments is that C=C bonds existence in these liquids plays a
