Abstract:
Composite polymer electrolytes for use in Polymer Electrolyte Membrane (PEM) fuel cells are disclosed. The electrolytes comprise sulfonated-organosilica hybrid electrolyte materials formed into a membrane. The sulfonated-organosilica hybrid electrolyte materials may be formed into a membrane by combining them in solution with Nafion® and solution casting the solution slurry to form a membrane. Alternatively, the sulfonated-organosilica hybrid electrolyte materials may be formed into a membrane by mixing them with an appropriate binder and applying the mixture to a suitable substrate. Also, the sulfonated-organosilica hybrid electrolyte materials may be formed into a membrane by sheer calendaring a co-precipitate of the sulfonated-organosilica hybrid electrolyte materials and Teflon®.
Abstract:
The present invention relates to a nanowire sensor and method for forming the same. More specifically, the nanowire sensor comprises at least one nanowire formed on a substrate, with a sensor receptor disposed on a surface of the nanowire, thereby forming a receptor-coated nanowire. The nanowire sensor can be arranged as a sensor sub-unit comprising a plurality of homogeneously receptor-coated nanowires. A plurality of sensor subunits can be formed to collectively comprise a nanowire sensor array. Each sensor subunit in the nanowire sensor array can be formed to sense a different stimulus, allowing a user to sense a plurality of stimuli. Additionally, each sensor subunit can be formed to sense the same stimuli through different aspects of the stimulus. The sensor array is fabricated through a variety of techniques, such as by creating nanopores on a substrate and electrodepositing nanowires within the nanopores.
