Abstract: A system, method, and apparatus for sensing analytes comprises assembling a sensor of at least one polymer and at least one fluorophore by mixing the polymer with the fluorophore, exposing the sensor to an analyte, and identifying the presence of the analyte according to a change in fluorescence of the sensor. The sensor can comprise a non-covalent complex of the at least one fluorophore and the at least one polymer. The at least one polymer can comprise a polymer capable of binding a metal ion. The at least one polymer is capable of binding a metal ion comprising an imidazole-containing polymer such as an N-vinylimidazole homo polymer and/or an N-vinylimidazole co-polymer.

Abstract: A cooling fan assembly, and method of operation, for use in an engine compartment of a vehicle is disclosed. The cooling fan assembly includes an electric motor having a motor shaft extending therefrom, a one-way clutch bearing mounted on and rotating with the motor shaft, and a cooling fan. The cooling fan includes a central hub with fan blades extending from the central hub. The central hub engages the one-way clutch bearing such that torque is transmitted from the motor shaft to the central hub in a first direction of rotation and torque is not transmitted from the motor shaft to the central hub in an opposed direction of rotation.
