Linking Perfluorosulfonic Acid Ionomer Chemistry and High-Current Density Performance in Fuel-Cell Electrodes.

Transport phenomena are key in controlling the performance of electrochemical energy-conversion technologies and can be highly complex, involving multiple length scales and materials/phases. Material designs optimized for one reactant species transport however may inhibit other transport processes. We explore such trade-offs in the context of polymer-electrolyte fuel-cell electrodes, where ionomer thin films provide the necessary proton conductivity but retard oxygen transport to the Pt reaction site and cause interfacial resistance due to sulfonate/Pt interactions.

UT Southwestern's Palliative Care Program: Measurable Patient Impact and Cost-savings.

The purpose of this analysis was to measure the impact of palliative care services on hospital charges in the 5 days prior to death-the most expensive time of a patient's life-and identify hospital service categories and patient financial classes yielding the highest savings from palliative care. The analysis population included UT Southwestern patients admitted to the hospital between October 1, 2013, and September 30, 2016. Palliative care patients were defined as any patient who received at least one completed palliative care order.

Evaluation of Quality of Life at Progression in Patients with Soft Tissue Sarcoma.

. Soft Tissue Sarcoma (STS) is a rare malignancy of mesodermal tissue, with international incidence estimates between 1.8 and 5 per 100,000 per year.
