A 532-nm-excited lunar Raman spectrometer (LRS) has been selected as a scientific payload of the Chang'e-7 mission, exploring mineralogy assemblages in south polar region. However, quantification dark-colored silicate minerals via spectroscopy is an urgent requirement for upcoming applications future and planetary explorations. Therefore, we conducted detailed laboratory studies on using ternar...

The structures of nonuniform binary hard-sphere mixtures and the correlation functions of uniform ternary hard-sphere mixtures were studied using a modified fundamental-measure theory based on the weight functions of Rosenfeld [Rosenfeld, Phys. Rev. Lett. 63, 980 (1989)] and Boublik-Mansoori-Carnahan-Starling-Leland equation of state [Boublik, J. Chem. Phys. 53, 471 (1970); Mansoori et al., J. ...

We have characterized the phase behavior of mixtures of the cationic surfactant cetyltrimethylammonium bromide (CTAB) and the organic salt 3-sodium-2-hydroxy naphthoate (SHN) over a wide range of surfactant concentrations using polarizing optical microscopy and X-ray diffraction. A variety of liquid crystalline phases, such as hexagonal, lamellar with and without curvature defects, and nematic,...

The imminent phaseout of R-11, R-12, and R·llS because of their high ozone depletion potentials has prompted many independent investigations of alternative or subst:i t:uee refrigeranes, ei eher as pure compounds or as mixtures of t:wo or more environmentally acceptable fluids. There are several motivations for investigating mixtures. There are very few pure compounds which can be used for refr...

The phase diagrams of some cholesterol-lipid mixtures exhibit two immiscibility regions along with a sharp cusp, pointing to a particular stoichiometry for possible lipid/cholesterol complex formation. It has been hypothesized that reactive cholesterol monomers are present in mixtures with cholesterol content greater than that at the cusp. To test this hypothesis, we have examined how the prese...

Thermophysical properties of dense supercriiicai water with special emphasis on dielectric permittivity are discussed. Phase diagrams and some critical curves of the binary systems H20—H2, H2O—N, H20—02, H20-CH4 and H20-He to 450 °C and 200 MPa are shown. H20-He tas a type I critical curve. A rational equation of state to calculate phase diagrams and critical curves for polar—non polar systems ...
