New preparations of molybdenum oxide tetrachloride, MoOCl4; tungsten oxide tetrachloride, WOCl4; molybdenum oxide trichloride, MoOCl3; molybdenum dioxide dibromide, MoO2Br2; and molybdenum oxide tribromide, MoOBr3, have been developed. It has been shown that all previous preparations of molybdenum pentachloride apparently contained some oxide tetrachloride. The magnetic susceptibility of pure molybdenum pentachloride has been measured over a temperature range.

The effect of scintillator particle size on high-resolution X-ray imaging was studied using zinc tungstate (ZnWO4) particles. The ZnWO4 particles were fabricated through a solid-state reaction between zinc oxide and tungsten oxide at various temperatures, producing particles with average sizes of 176.4 nm, 626.7 nm, and 2.127 μm; the zinc oxide and tungsten oxide were created using anodization. The spatial resolutions of high-resolution X-ray images, obtained from utilizing the fabricated particles, were determined: particles with the average size of 176.4 nm produced the highest spatial resolution. The results demonstrate that high spatial resolution can be obtained from ZnWO4 nanoparticle scintillators that minimize optical diffusion by having a particle size that is smaller than the emission wavelength.
