the former is a heavy colourless liquid of low volatility (vapour pressure 2-3 mm. at 0°), while the monoiodido is a liquid of boiling point 45.8° and melting point-56.5°, which resembles methyl iodide in appearance.doi:10.1038/144328a0MADDOCK, A. G...
Fluid boiling is likely an important step for further concentration of Mo rather than a direct trigger for Mo precipitation, because the coexistence of vapour-rich and halite-bearing brine inclusions may confirm the occurrence during Mo precipitation in the Chalukou deposit (Liu et al., 2014; Li...
Measurement of Volumetric Mitral and Aortic Blood Flow Based on a New Freehand Three-dimensional Colour Flow Imaging Method. An in vivo Validation Aims: To validate a new three-dimensional (3D) colour flow method used to calculate cardiac output (CO) in aortic and mitral blood flow. Methods:...
If the operation is performed in a platinum tube, a large quantity of fused fluoride remains in the tube. The tetrafluoride of platinum, PtF4, formed upon the wires, consists either of fused masses of a deep red colour, or of small buff-coloured crystals resembling anhydrous platinum chloride...
Trifluoramine oxide ONF3 which is a colourless gas of melting-point about - 161.5 DEG C. and boiling-point about - 89 DEG C. is prepared by reacting difluoramine with ClF3 and an oxygenated halogen compound, for example ClO2, FClO2 or FClO3. The reactants are first condensed at ...
