? COVER CREDIT: Scanning electron microscope (SEM) images of nylon press felt fibers are compared to evaluate relative corrosivity of several common pulp and paper industry oxidants. This investigation by Buschmann and Kaplan demonstrates the application of Clean Chemistry’s novel peracetate/singlet oxygen chemistry for post-bleach plant pulp brightening and potential impacts of carryover onto paper machines relative to common oxidants used in mill operations (p. 297).
