  • Publication number: 20240112823
    Abstract: Disclosed are a method and device for evaluating damage caused by secondary stress to a vacuum vessel, a terminal device, and a medium, to perform following steps: obtaining secondary stress of a vacuum vessel that passes a primary-stress failure evaluation; obtaining structural damage parameters of the vacuum vessel when determining, based on evaluation parameters for the primary-stress failure evaluation of the vacuum vessel and the obtained secondary stress, that the vacuum vessel meets a precondition for a progressive deformation; and determining, based on the obtained structural damage parameters, whether the vacuum vessel meeting the precondition for the progressive deformation experiences structural damage due to the progressive deformation. In this way, a vacuum vessel of a nuclear fusion reactor can be evaluated based on damage caused by the secondary stress.

  • Patent number: 11422403
    Abstract: Described herein are embodiments of squarylium compounds for use as filters in light-emitting and/or display devices. One problem of known quarylium dyes is that strong nucleophiles can attack the electron-deficient cyclobutene ring which can lead to a loss of the dye's colour. Another potential drawback with squaraine dyes can be their tendency to form aggregates, which can lead to a substantial broadening of their absorption bands. Use of the present compounds in filters address these problems.
