Abstract: Compositions, articles, systems, and methods for sensing and/or authentication using luminescence imaging are generally provided. In some embodiments, an article (or packaging material of an article) is associated with an emissive material comprising an emissive species (e.g., a luminescent species). In some cases, the emissive species has an emission lifetime of at least 10 nanoseconds (ns). In some cases, a characteristic of an article (e.g., identity, authenticity, age, quality, purity) may be determined by obtaining an image (or series of images) comprising time-dependent information related to an emissive species. In certain instances, for example, the emission lifetime of an emissive species may be determined from an image (or series of images). Since the emission lifetime of an emissive species may be modified by a number of factors, including but not limited to binding or proximity to other molecules (e.g.

Abstract: Particle-based detection of analytes including, for example, systems, kits, and methods for growth, isolation, and/or monitoring of analytes are generally disclosed. In some embodiments, the systems and methods described herein are generally directed to the capture and/or concentrating of a target species (e.g., analyte) to be detected and/or monitored. In some embodiments, the materials, systems, and methods described herein may be used to create luminescent signals in response to the presence of selected analytes such as bacteria, viruses, and parasites. In some cases, the target analyte is a pathogenic bacteria, a pathogenic virus, a pathogenic parasite, or toxin.

Abstract: A method of detecting a stimulus can include detecting an output from a radio frequency identification tag including a sensor. A smartphone-based sensing strategy can use chemiresponsive nanomaterials integrated into the circuitry of commercial Near Field Communication tags to achieve non-line-of-sight, portable, and inexpensive detection and discrimination of gas phase chemicals (e.g., ammonia, hydrogen peroxide, cyclohexanone, and water) at part-per-thousand and part-per-million concentrations.

Abstract: Components, systems, and methods for gas sensing identification are generally disclosed. In some embodiments, a characteristic of an article (e.g., identity, authenticity, property, product associated information such as age or quality, etc.) may be determined by determining the presence (e.g., an amount) or absence of a chemical compound (or compounds) emanating from the article. For example, the presence or absence of the compound (or compounds) emanating from the article identifies a characteristic of the article. In some embodiments, the chemical compound(s) has been proactively added to the article. That is to say, in some embodiments, the chemical compound is not inherently associated with the article but is added in order to, for example, identify a characteristic of the article.

Abstract: A major challenge in the development of anion exchange membranes for fuel cells is the design and synthesis of highly stable (chemically and mechanically) and conducting membranes. Membranes that can endure highly alkaline environments while rapidly transporting hydroxides are desired. A design for using cross-linked polymer membranes is disclosed to produce ionic highways along charge delocalized pyrazolium and homoconjugated triptycenes. The ionic highway membranes show improved performance in key parameters. Specifically, a conductivity of 111.6 mS cm?1 at 80° C. was obtained with a low 7.9% water uptake and 0.91 mmol g?1 ion exchange capacity. In contrast to existing materials, these systems have higher conductivities at reduced hydration and ionic exchange capacities, emphasizing the role of the highway. The membranes retain more than 75% of initial conductivity after 30 days of alkaline stability test.
