    摘要: The present disclosure describes thermally insulating glass laminates that prevent heat from escaping from heated cavities. In some embodiments, the thermally insulating glass laminates comprise a low or non-conductive coating layer that forms a chemical bond with at least one substrate, wherein the coating layer has a thickness of about 0.010 inches or less, wherein a plurality of glass spacers is submerged in the coating layer, and wherein at least one sealed cavity of gas molecules is created between the substrates and around the glass spacers. Since there is a small amount of gas molecules in each cavity, convective heat transfer between the substrates is minimized thereby minimizing heat loss through the laminates into the surrounding environment.

    摘要: The present disclosure relates to a lithium ion-conducting glass ceramic which comprises a residual glass phase that is also ion-conducting, a process for the production thereof as well as its use in a battery. The glass ceramic according to the present disclosure comprises a main crystal phase which is isostructural to the NaSICon crystal phase, wherein the composition can be described with the following formula: Li1+x−yMy5+Mx3+M2−x−y4+(PO4)3, wherein x is greater than 0 and at most 1, as well as greater than y. Y may take values of between 0 and 1. Here, the following boundary condition has to be fulfilled: (1+x−y)>1. Here, M represents a cation with the valence of +3, +4 or +5. M3+ is selected from Al, Y, Sc or B, wherein at least Al as trivalent cation is present. Independently thereof, M4+ is selected from Ti, Si or Zr, wherein at least Ti as tetravalent cation is present. Independently thereof, M5+ is selected from Nb, Ta or La.

    摘要: A method and system for measuring an inert gas by an ion probe. Embedding a to-be-measured sample into an epoxy resin, to obtain a sample target, where the to-be-measured sample includes an inert gas atom; after putting the obtained sample target into an analysis chamber of the ion probe, vacuumizing the analysis chamber, where the ion probe includes a primary ion source, an electron gun, a mass analyzer, and an ion detector; bombarding the sample target by using a primary ion beam formed by the primary ion source to release the inert gas atom in the sample target; ionizing the released inert gas atom by using an electron beam formed by the electron gun to form an inert gas ion; and analyzing a secondary ion containing the inert gas ion by using the mass analyzer and the ion detector to achieve measurement of the inert gas.

    摘要: A system and a method for reducing drag on the aft-fuselage of an aircraft are provided, which system and method utilize at least one finlet provided on each side of the aft-fuselage of an aircraft for reducing drag—on the aft-fuselage, which finlets are (i) positioned at the rear half of an upswept portion of the aft-fuselage starting at a breakline, (ii) positioned in the path of the vortices generated by the aft-fuselage, and (iii) oriented at 1 to 9 degrees angle relative to the local airflow about the aft-fuselage of the aircraft to straighten the airflow about the aft-fuselage. In addition, the finlets generate an induced secondary vortex having an opposite rotation direction relative to the rotation direction of the vortices generated by the aft-fuselage, thereby counteracting the vortices generated by the aft-fuselage.
