Abstract: A process of utilizing a water-sensitive fluorophore for moisture content evaluation in a hygroscopic polymer includes forming a blend that includes a hygroscopic polymer resin and a water-sensitive fluorophore. The process includes forming pellets having a particular geometry from the blend, determining fluorescence properties of at least one of the pellets, and determining moisture content of at least one of the pellets. The process also includes generating a calibration curve for the particular pellet geometry by correlating the fluorescence properties with the moisture content. The process further includes providing the calibration curve for non-destructive moisture content evaluation of a material derived from the pellets.

Abstract: A process of forming a sustained-release pesticide coating, a process of forming a sustained-release pesticide capsule, and a sustained-release pesticide coating are disclosed. The process of forming the sustained-release pesticide coating includes depositing a first layer that includes a first pesticide onto a surface, and depositing a second layer that includes a photodegradable material onto the first layer. The process of forming the sustained-release pesticide coating also includes depositing a third layer that includes a second pesticide onto the second layer. The process of forming the sustained release pesticide capsule includes selecting a pesticide, selecting a photosensitive compound, and encapsulating the pesticide in a photosensitive capsule that includes a polymer formed from the photosensitive compound. The sustained-release pesticide coating includes a pesticide and a material having a photosensitive component. The material is in contact with the pesticide, and temporarily prevents the pesticide from contacting a surface.

Abstract: Method, apparatus, and computer program product are provided for determining a maximum temperature to which a perishable good or other temperature sensitive item was exposed. In some embodiments, a capacitance of a circuit provided on a substrate is measured. The circuit includes capacitor(s) each having first and second plates separated from each other by an ionic liquid (IL) in a solid state. The IL melts at a predetermined temperature and flows away from the first and second plates into a void. In some embodiments, the predetermined temperature at which the IL melts is different for each capacitor. For example, each capacitor in the circuit may employ a different N-alkyl bezothiazolium salt. A maximum temperature of exposure is determined based on the measured capacitance. In some embodiments, a decision of whether to discard the perishable good or other temperature sensitive item may be based on the determined maximum temperature.

Abstract: An article of manufacture. The article of manufacture includes a ring-opened lactide copolymer. The ring-opened lactide copolymer is formed in a process that includes reacting a functionalized lactide monomer with a BPA-derived monomer. The reaction forms a lactide copolymer, which is reacted to form the ring-opened lactide copolymer.

Abstract: In an example, a process includes applying a platinum catalyst ink solution to a polymeric substrate to form a platinum-coated polymeric material having a first catalytic surface area. The process further includes utilizing a laser to process a portion of the platinum-coated polymeric material to form a patterned platinum-coated proton exchange membrane (PEM) material. The patterned platinum-coated PEM material has a second catalytic surface area that is greater than the first catalytic surface area.

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: A method and structure are provided for implementing stub-less printed circuit board (PCB) vias and custom interconnect through laser-excitation conductive track structures. Stub-less printed PCB vias are formed which terminate at desired signal layers by controlled laser excitation without stubs or the need to back-drill to remove such stubs.
