Membranes permeable to an analyte may overlay the active sensing region of a sensor to limit the analyte flux and improve the response linearity of the sensor. Temperature variation of the analyte permeability can be problematic in some instances. Polymeric membrane compositions having limited variation in analyte permeability as a function of temperature may comprise: a polymer backbone comprising one or more side chains that comprise a heterocycle; and an amine-free polyether arm appended, via an alkyl spacer or a hydroxy-functionalized alkyl spacer, to the heterocycle of at least a portion of the one or more side chains.

An optically transparent matrix including a molecule containing a hydroxyazobenzene group or its derivative embedded in the matrix. An optical system including the optically transparent matrix, an isomerizing light source, and one or more light detector(s) for measuring absorbance changes from the optically transparent matrix. A method for measuring the quantity of hydrogen bonding gaseous molecules.

A thermothickening fluid is provided which comprises a liquid phase; a first polymer comprising functional groups and having a room temperature solubility in the liquid phase; and a second, different polymer comprising functional groups and having a room temperature solubility in the liquid phase, wherein functional groups on the first polymer are capable of associating with functional groups on the second polymer to form complexes, and the room temperature solubility of the first polymer is greater than the room temperature solubility of the second polymer. The fluid is a colloid at room temperature, a solution at an elevated temperature, and exhibits a thermothickening/thinning transition viscosity value at a thermo-thickening/thinning transition temperature between room temperature and the elevated temperature.
