The freezing point depression of freshly excised frozen tissues, pulverized in a hydraulic press or in a mortar, is greater than that of plasma. Even at 0 degrees C. the freezing point depression of such homogenates increases significantly with time. Dilution data indicate that such freezing point data are valid. The presence of intact cells has been shown in smears of tissues pulverized in a m...
Video microscopy was employed to explore crystallization of colloidal monolayers composed of diameter-tunable microgel spheres. Two-dimensional (2D) colloidal liquids were frozen homogenously into polycrystalline solids, and four 2D criteria for freezing were experimentally tested in thermal systems for the first time: the Hansen-Verlet freezing rule, the Lowen-Palberg-Simon dynamical freezing ...
We examined how 1 year students (10th grade) of Greek Senior High School could conceptualize the influence of the molecular weight of saturated fatty acids on the melting and the freezing point, during the ‘change of phase’ phenomenon using the Microcomputer-Based Laboratory (MBL) system. Students had to freeze a melted substance, observing at the same time the change of its temperature and try...
Acidified steam condensates that are enriched in SO4 but poor in Cl are found in the upper parts of many geothermal systems occurring in steep terrains. In this paper, we characterize the chemical evolution of these acid-sulfate fluids by combining mineral and fluid inclusion relationships from Karaha-Telaga Bodas with numerical simulations of water-rock interactions. These interactions were mo...
