Polymer electrolyte membrane (PEM) fuel cells require precise temperature and moisture controls to be at their best. Specifically, the researchers used synchrotron-based micro X‐ray computed tomography (CT) to visualize and to quantify the water distribution within gas diffusion layers subject to a thermal gradient. —Shum et al.

In nature, the resilient lignin polymer helps provide the scaffolding for plants, reinforcing slender cellulosic fibers—the primary raw ingredient of cellulosic ethanol—and serving as a protective barrier against disease and predators. Over the course of a year, the team amassed 1.3 —Loukas Petridis. Pretreatment.
