Coadsorption phase diagram for KrÕCCl4 on graphite
We present the results of an extensive calorimetric study of krypton coadsorbed on graphite precoated with a saturated monolayer of carbon tetrachloride. Combining the heat capacity data with film equation of state measurements from a previous study @W. J. Weber and D. L. Goodstein, Phys. Rev. Lett. 83, 3888 ~1999!# permits construction of the Kr/CCl4 coadsorption phase diagram between 77 and 1...
متن کاملCoadsorption phase diagram for CH4/CCl4 on graphite
We present an extensive thermodynamic study of methane coadsorbed on graphite precoated with a saturated monolayer of carbon tetrachloride. A combination of heat capacity and volumetric equation of state data permit construction of the multilayer coadsorption phase diagram between 70 and 115 K. Displacement of the preadsorbed CCl4 by CH4 occurs by a continuous process across the temperature ran...
متن کاملTetrafluoromethane monolayer physisorbed on graphite : its orientational walls and its complex phase diagram
2014 Neutron diffraction results for a monolayer of CF4 physisorbed on different graphites show the complexity of the system, mainly due to the non spherical shape of the admolecule. From our neutron data and LEED results [6] we recognize at least 6 different phases. These are, with decreasing temperature, liquid, plastic, commensurate solid, incommensurate solid, incommensurate tilted and a su...
متن کاملMore on the phase diagram of Laponite.
The phase diagram of a charged colloidal system (Laponite) has been investigated by dynamic light scattering in a previously unexplored range of salt and clay concentrations. Specifically, the clay weight and salt molar concentrations have been varied in the ranges C(w) = 0.004 divided by 0.025 and C(s) = (1 x 10(-3) divided by 5 x 10(-3)) M, respectively. As in the case of free salt water samp...
متن کاملOn the Yttrium Tantalate – Zirconia phase diagram
The phase diagram for the YTaO4-ZrO2 quasi-binary has been determined up to 1600 °C. There are three distinct compositional regimes: an extensive YTaO4 solid solution, an extensive ZrO2 solid solution and a two-phase intermediate region. The addition of ZrO2 to YTaO4 decreases the M–T transition temperature almost linearly from 1426 °C to approximately 450 °C at the solubility limit (∼28mol% Zr...
