Erratum


Owing to unfortunate figure reproduction issues, the figures for the printed and on-line editions of the article “In-situ Measurements of Temperature Distributions in a Microwave-Heated Cavity” by Finegan et al. (Volume 52, No. 8, August 2006, pp. 2727–2735, DOI: 10.1002/aic.10897) did not reflect the quality of the originally-submitted artwork, and many of the features crucial to the interpretation and discussion of the results were not discernable. These figures are reproduced here in their original quality to enable correct visualization of the experimental and predicted temperature distributions in a microwave heated cavity. 1, 2, 3, 4, 5, 6, 7, 8, 9

Figure 1.

Temperature dependent fluorescence of Rhodamine B-labeled Dextran and Rhodamine 110.

Figure 2.

(a) Experimental microwave applicator showing location of the isolator, dummy load, tuner, cavity and short circuit. Optical ports for the introduction of the excitation beam and the observation of the emitted fluorescence signals are shown; (b) microwave cavity with sample cell prior to insertion; and (c) a view of the sample cell holder with opening for access by the laser.
