Abstract: A vehicle coolant system includes a pipe configured to facilitate a flow of vehicle coolant through the pipe, a light source configured to transmit at least one wavelength of light through the vehicle coolant, and a signal detector configured to receive at least one wavelength of light transmitted through the vehicle coolant, and to generate a signal intensity value corresponding to a measured intensity of the at least one wavelength of light received at the signal detector. A controller is configured to receive the signal intensity value from the signal detector, identify a coolant contamination threshold value corresponding to the vehicle coolant, compare the signal intensity value received from the signal detector to the coolant contamination threshold value, and initiate a vehicle coolant remedial action according to a result of comparing the signal intensity value received from the signal detector to the coolant contamination threshold value.

Abstract: A battery cell having an anode and a cathode with a catalyzed separator interposed therebetween, and sealed within a cell case is described. The catalyzed separator is a substrate having a catalyzed coating arranged thereon. The catalyzed coating includes a bimetallic catalyst arranged on a support material. The bimetallic catalyst includes rhodium or ruthenium and a second transition metal. Lithium in zeolite functions as a catalyst promoter to accelerate a hydroformylation reaction.

Abstract: A method for detecting a contaminant in a vehicle coolant system during service includes contacting a chromophore impregnated strip and a heat transfer fluid sample, where the chromophore impregnated strip includes a complexing agent selected to form a complex with the contaminant that causes a color change in the chromophore impregnated strip and thereby indicates the presence of the contaminant in the heat transfer fluid sample.
