    Abstract: Global icephobic performance of a passive deicing structure may be achieved by including one or more ice nucleating zones that are configured, preselected, and/or arranged to promote selective formation of ice. Ice nucleation zones may be configured, preselected, and/or arranged to form ice that is weakly adherent and, hence, may be removed by sufficient shear force. Ice nucleation zones typically include nucleating particles to promote selective ice formation. Passive deicing structures typically include both ice nucleation zones and ice resisting zones, arranged to facilitate ice removal by shear force. Passive deicing structures may be used on apparatuses such as vehicles (e.g., aircraft) to mitigate the effects of ice formation on exposed surfaces.

    Abstract translation: 被动除冰结构的全球性的积雪性能可以通过包括一个或多个构成，预选和/或布置成促进冰的选择性形成的冰成核区来实现。 冰成核区可以被构造，预选和/或布置成形成弱粘附的冰，因此可以通过足够的剪切力去除。 冰成核区域通常包括成核颗粒以促进选择性冰的形成。 被动除冰结构通常包括冰成核区和防冰区，布置成便于通过剪切力除冰。 被动除冰结构可用于诸如车辆（例如飞行器）的装置上以减轻暴露表面上的冰的影响。

    Abstract: Aspects of the present disclosure relate to Schiff base oligomers and uses thereof. In at least one aspect, an oligomer is represented by Formula (IV) wherein each instance of R9 is independently selected from the group consisting of alkyl, cycloalkyl, aryl, heteroaryl, and ether. Each instance of R28 and R29 of Formula (IV) is independently selected from the group consisting of hydrogen, alkyl, cycloalkyl, and aryl. Each instance of R33 of Formula (IV) is independently selected from the group consisting of alkyl, cycloalkyl, aryl, heterocyclyl, and a bond. Each instance of R41 of Formula (IV) is independently —NH— or a bond and each instance of R40 is independently —NH— or —NH—NH—. Each instance of R42 of Formula (IV) is independently —NH— or a bond and each instance of R43 is independently —NH— or —NH—NH—.

    Abstract: Aspects of the present disclosure generally relate to systems and methods for monitoring the structural health of components. In an aspect is provided a system for monitoring structural health of a component that includes a mechanotropic elastomeric (ME) layer at least partially disposed on a surface of the component, the ME layer having a first portion corresponding to a first end of the component and a second portion corresponding to a second end of the component; a fiber optic light guide coupled to the first end; and a detector coupled to the second end. In another aspect is provided a method that includes pulsing an electromagnetic energy source coupled to a system comprising a ME layer; and detecting a wavelength or wavelength range by a detector, the detected wavelength or wavelength range being responsive to an amount of stimulus and being indicative of a deformation in a component.

    Abstract: Disclosed is a curable sealant composition including: (i) a thiol-terminated prepolymer and/or monomers thereof, wherein the thiol-terminated prepolymer is a polythioether or a polysulfide; (ii) an “ene” crosslinker having a molecular weight of about 100 to about 5000; and (iii) a pH indicator molecule including a quantum dot functionalized with a pH-responsive ligand. Methods for determining a sufficient cure state of a composition by combining the thiol-terminated prepolymer and/or monomers thereof and the “ene” crosslinker with a pH indicator molecule, including a quantum dot functionalized with a pH-responsive ligand, and (ii) then subjecting a resultant mixture of (i) to curing conditions until the mixture changes its color are also disclosed.
