The DISMT ("Dual Indicator System for Mixing Time'') mixing time/distance diagnostic encodes semi-quantitative visualization of liquid/liquid mixing processes in color changes. In DISMT, two liquids, one red and one blue, are mixed to produce a yello

The liquid fuel that accumulates in the engine manifold and cylinders during cold start conditions is thought to contribute significantly to excess hydrocarbon emissions. Two fluorescent dopants, cyclohexanone and 2-methyl-cyclopentanone, have been t

Four strongly emitting fluorescent molecules have been identified as effective liquid-phase thermometers for use at temperatures as high as 175 °C under oxygen-saturated conditions. In each case, the thermometry is based on shifts and/or changes in

This paper reports the development of exciplex-based vapor/liquid visualization systems based on exciplexes formed from tertiary amines and fluorine-substituted benzene and/or toluene. These systems are expected to be virtually coevaporative with sol
