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.

Abstract: Embodiments described herein may be useful in the detection of analytes. The systems and methods may allow for a relatively simple and rapid way for detecting analytes such as chemical and/or biological analytes and may be useful in numerous applications including sensing, food manufacturing, medical diagnostics, performance materials, dynamic lenses, water monitoring, environmental monitoring, detection of proteins, detection of DNA, among other applications. For example, the systems and methods described herein may be used for determining the presence of a contaminant such as bacteria (e.g., detecting pathogenic bacteria in food and water samples which helps to prevent widespread infection, illness, and even death). Advantageously, the systems and methods described herein may not have the drawbacks in current detection technologies including, for example, relatively high costs, long enrichment steps and analysis times, and/or the need for extensive user training.

Abstract: A tag for detecting an analyte can include a radio frequency identification tag including a sensor portion, the sensor portion configured to change resistivity when the radio frequency identification tag contacts or interacts with an analyte, whereby the resistivity change alters an output of the radio frequency identification tag, wherein the sensor portion includes a circuit, and wherein the sensor portion is configured to activate the circuit or deactivate the circuit when contacted or having interacted with the analyte, where the sensor portion includes a plurality of carbon nanotubes associated with a chemically-degradable polymer. In certain embodiments, the chemically degradable polymer can be a metallo-supramolecular polymer.

In some embodiments, the composition comprises redox active polymers comprising an electrophilic nitrogen containing heterocycle and an electron rich aromatic compound. In some embodiments, the composition comprises a triazine-based polymer. The electroactive polymers may be formed, in some cases, by polymerizing an electrophilic nitrogen containing heterocycle-based unit with an electron rich aromatic compound in the presence of heat and an acid-based catalyst. The resulting electroactive polymers may be suitable as polymer films for use as electrodes in energy storage devices. The polymer films disposed as electrodes can improve the energy density of such devices.
