Under high current density operation, water generation at the cathode of polymer electrolyte fuel cells (PEFCs) floods the electrode, resulting in severe mass transport limitation and an associated voltage drop. Water management is thus of crucial importance in improving the overall performance of fuel cell systems. Gas diffusion layers (GDLs) with independent pathways for either gaseous oxygen or liquid water transport present a potential solution to this issue.

The size is a key property of a nucleus. Accurate nuclear radii are extracted from elastic electron scattering, laser spectroscopy, and muonic atom spectroscopy. The results are not always compatible, as the proton-radius puzzle has shown most dramatically.

We conducted a study of aviators who experienced a close brush with death at work, in an effort to better understand how such events influence thoughts about work. Importantly, our initial interviews suggested that participants used conversational storytelling about their close brush with death as a means of enhancing the meaningfulness of their work. That initial finding presented us with a puzzle, as the literatures connecting storytelling to the meaning of work view stories as useful for not (i.

Ionizing radiation is a potent environmental mutagen, producing damaged bases and single and double-stranded DNA breaks. Acute high-dose radiation exposure is therefore toxic, causing cellular and organismal mortality, while lower doses can give rise to high mutation rates and cancer. Radiation sensitivity furthermore varies dramatically between organisms and cell types, with certain organisms exhibiting extreme tolerance to ionizing radiation.
