  • Pressure‐induced phase transition of Methyl Alcohol doped castor oil
    High‐pressure science and technology, 2008
    Co-Authors: R. Wiśniewski, R. M. Siegoczyński, P. Borowik, M. Krukowski, M. Tucholski
    Abstract:

    Pure castor oil and their 5, 10, 15, and 20 of Methyl Alcohol volume % mixtures at pressure up to 1.0 GPa at room temperature have been investigated. The phase transitions relaxation times dependent on Methyl Alcohol content and applied initial pressure have been observed. These phase transitions were detected by the decrease of volume (∼2%), the decrease of electric permittivity (by ∼30%) and strong light scattering effects.

  • Pressure induced volume changes in triolein with addition of Methyl Alcohol
    High Pressure Research, 2007
    Co-Authors: D. B. Tefelski, Aleksander J. Rostocki, R. Kościesza, R. M. Siegoczyński
    Abstract:

    A high-pressure research of triolein with addition of small amount of Methyl Alcohol has been made. A cylindrical chamber with a simple piston system has been used to generate pressure. Changes of pressure, volume, temperature and capacitance were collected using an advanced data acquisition system. In this paper, we present volume changes as function of pressure. An improved method of volume measurement has been applied allowing for very accurate measurement of piston position with accuracy of 0.01 mm. Since the high-pressure phase transition in triolein was presented in Siegoczynski [R.M. Siegoczynski, Reports of the Institute of Physics, Publishing House of the Warsaw Technical University of Technology, No. 46 (1998)], authors have checked an influence of Methyl Alcohol on this phase transition.

  • VISCOSITY OF THE Methyl Alcohol DOPED CASTOR OIL HIGH-PRESSURE PHASE
    High Pressure Research, 2003
    Co-Authors: R. Wiśniewski, R. M. Siegoczyński
    Abstract:

    High-pressure apparatus (up to 1 GPa) for viscosity measurements (using the capillary method) of a high-viscous medium has been constructed. High-pressure phases of pure castor oil and Methyl Alcohol doped castor oil, which had been obtained earlier, were generated and their viscosity measured. Values of viscosity as high as 160kPas for pure castor oil and 60kPas for Methyl Alcohol doped castor oil (about 5 of volume%), at a small shear rate parameter equal to about 0.1s−1, were measured and their structural (tixotropic) type viscosity (consistency) were discovered.

  • effect of Methyl Alcohol on the morphology and conformational characteristics of silk sericin
    International Journal of Biological Macromolecules, 2003
    Co-Authors: Haeyong Kweon, Young Hwan Park
    Abstract:

    Effects of Methyl Alcohol on the morphology and conformational characteristics of silk sericin (SS) were studied. Scanning electron microscope showed that morphology of SS lyophilized was dramatically changed from sponge-like structure to spherical fine particle type. X-ray diffraction method, infrared spectroscopy, and differential scanning calorimetry showed that the conformation of SS was random coil structure regardless of the addition of Methyl Alcohol. On the other hand, circular dichroism showed that the molecular states of SS were more densely packed.
