  • Patent number: 11959164
    Abstract: This invention provides a process or fabrication method of forming broadband anti-reflective (AR) coating over the mid-IR fluoride fiber for high power laser applications in mid-IR wavelength range. The AR coating consists of multiple-pair Lithium fluoride (LiF) and Al2O3, and was deposited by electron beam physical vapor deposition with an iron assistant source at low temperature (<60° C.). A thin encapsulation layer of Al2O3 was applied over the AR coating by atomic layer deposition technology. The measurements show the coating has a reflectivity of <1-1.5% in the range of 1.5-5.5 ?m. The laser induced damage threshold (LIDT) test shows the damage threshold is greater than 8.9 MW/cm2 with no sign of any damage on the coating exposed to atmosphere. The durability and environmental tests of the AR coating with PVD coated encapsulation layer show good humidity resistance in open air and no degradation of film quality and optical performance are observed.

  • Publication number: 20240116773
    Abstract: The present invention relates to a method for preparing high-purity vanadium pentoxide from vanadium-bearing shale by all-wet process. The technical solution is: the “Gradient continuous leaching system of vanadium-bearing shale” is used to wet activate and compound leach vanadium-bearing shale to obtain vanadium-containing acid leachate. The “pH adjusting device of the vanadium-containing acid leachate” is used to adjust the pH of vanadium-containing acid leaching leachate. The post-treatment solution is subjected to hydroxime countercurrent extraction after oxidation, and the raffinate returns to the water using in the wet activation and electrodialysis after neutralization, and the loaded organic phase is regenerated by countercurrent reduction stripping. The regenerated organic phase directly returns to hydroxime countercurrent extraction.
