  • Publication number: 20260316375
    Abstract: The present invention relates to articles comprising thiourea polymer networks having thioether crosslinks, alkene-functionalized thiourea polymers, liquid resins comprising such alkene-functionalized thiourea polymers and process of making and using such alkene-functionalized thiourea polymers, liquid resins and articles. The aforementioned liquid resin is converted to an article by UV casting, thermal casting, VP and/or direct ink writing processes. The 3D article has the desired mechanical properties. In one aspect, such mechanical properties include having a maximum stress of at least 100 psi and at least 100% strain at break. In addition to the desired mechanical properties, Applicants' 3D articles can be self-healing and/or reprocessable.

  • Publication number: 20060114094
    Abstract: A low cost, low profile, small size and high performance electronic device for use in, e.g., electronic circuits where a transformer, inductor, or mixer is required. In one exemplary embodiment, the device includes a “binocular” ferrite core comprising a plurality of core apertures and windings. The core is shaped with one or more channels which are at least partly plated (metallized) so as to allow bonding of the winding terminations directly to the core. The placement of these plated areas allows simplified surface mounting. The plated areas also obviate a termination header, thereby simplifying the manufacture of the device and reducing its cost. Methods for manufacturing the device are also disclosed.
