Abstract: A process of utilizing a heat-activated conductive spinel material for PCB via overcurrent protection includes forming a PCB laminate structure that includes a spinel-doped insulator layer having a heat-activated conductive spinel material incorporated into a dielectric material as a spinel-based electrically non-conductive metal oxide. A sensing via is formed in the PCB laminate structure at a location that is proximate to a power via in the PCB laminate structure. The sensing via is electrically isolated from the power via by a region of the spinel-doped insulator layer and is electrically connected to a monitoring component configured to detect current flow through the sensing via that results from an overcurrent event in the power via that generates sufficient heat to cause the spinel-based electrically conductive metal oxide to release metal nuclei into the region to provide a conductive pathway through the region from the power via to the sensing via.

Abstract: A process includes providing furan-2,5-dicarboxylic dimethyl ester (FDME), reacting the FDME with a Grignard reagent to form a bis-alkylketone furan having R groups selected from the group consisting of a C1-C20 linear alkyl chain, a C2-C24 branched alkyl chain, and a hydrogen atom. An additional process includes mixing a 3,4-dibrominated bis-alkylketone furan with potassium carbonate, and adding ethyl-mercaptoacetate to the mixture. This process also includes stirring the mixture to form a bis-alkyl-DTF diester fused ring structure, which is then brominated to form a dibromo-DTF compound.

Abstract: A process of forming a hydrophobic, conductive barrier on a metallic surface includes coating the metallic surface with an organic, conductive material. The organic, conductive material includes a conductive group having two or more alkyne groups and a dithiocarbamate group to bind the organic, conductive material to the metallic surface.

Abstract: A flame retardant sugar-derived molecule, a process for forming a flame retardant sugar-derived molecule, and an article of manufacture comprising a flame retardant sugar-derived molecule are disclosed. The flame retardant sugar-derived molecule can be synthesized from arabitol, xylitol, arabic acid, or xylonic acid obtained from a bio-based source, and can have at least one phosphoryl or phosphonyl moiety. The process for forming the flame retardant sugar-derived molecule can include reacting arabitol, xylitol, arabic acid, or xylonic acid and a flame retardant phosphorus-based molecule to form the flame retardant sugar-derived molecule.

Abstract: An impact resistant polyhexahydrotriazine polymer, processes of forming an impact resistant polyhexahydrotriazine polymer, and an article of manufacture comprising an impact resistant polyhexahydrotriazine polymer are disclosed. The impact resistant polyhexahydrotriazine polymer includes at least one hexahydrotriazine group and at least one chain comprising an allylic portion and a styrenic portion. Variations in the chain control properties of the impact resistant polymer. The process of forming the impact resistant polyhexahydrotriazine polymer includes reactions between formaldehyde and at least two classes of monomer that form hexahydrotriazine groups and impact resistant chains. Adjusting relative monomer concentrations controls properties of the impact resistant polyhexahydrotriazine polymer. The article of manufacture contains a material that has an impact resistant polymer. Impact resistance of the impact resistant polyhexahydrotriazine polymer is dependent upon variation in relative amounts of monomers used in its synthesis.

Abstract: A method for forming a photosensitizer product that is resistant to absorption by living tissue that may include binding a photosensitizer compound with an oxide-containing particle to provide the photosensitizer derivative having a microscale size, and mixing the photosensitizer derivative into a lotion. The microscale size of the photosensitizer derivative obstructs absorption by cell tissue.

Abstract: An apparatus is configured with a component having a coating comprising a material in a first phase (e.g., solid and/or liquid phase) with a transition temperature. The component is mechanically and/or electrically attached to a substrate. Exposure of the coating to a temperature that meets or exceeds the transition temperature causes the material to undergo a phase change. The phase change of the material alters the position of the component, including separation of the component from the substrate. The separation disrupts the attachment, thereby mitigating damage to the substrate and/or component.

Abstract: A process of forming a gluten-derived flame retardant material includes forming an amine-functionalized flame retardant molecule that includes an aryl halide group and a phosphorus moiety. The process also includes chemically reacting the amine-functionalized flame retardant molecule with a gluten protein under transamidation conditions to bind the phosphorus moiety to a first portion of the gluten protein. The process further includes initiating a cross-coupling reaction between the aryl halide group and amine group of a second portion of the gluten protein to form a gluten-derived flame retardant material.
