K. Hsiao, C. Sasmal, J. R. Prakash, C. M. Schroeder
Journal Paper J. Rheol., 61, 151–167, 2017.

Featured article in the January 2017 issue of the Journal of Rheology. This paper and the back-to-back companion paper (J. Rheol., 61, 169–186, 2017) have been highlighted on the front cover of the January 2017 issue of the Journal of Rheology, with cover artwork depicting the research. The following description appears inside the cover: "The images on the cover highlight the study of DNA in planar extensional flows and subsequent relaxation in experiments in the paper by Kai-Wen Hsiao, Chandi Sasmal, J. Ravi Prakash and Charles M. Schroeder (p. 151) and in Brownian dynamics simulations in the paper by Chandi Sasmal, Kai-Wen Hsiao, Charles M. Schroeder and J. Ravi Prakash (p. 169). The bottom image is representative of the superb comparisons between experiment and simulation shown in figure 7 of the latter paper".
