Protonic Ceramic Electrochemical Cell for Efficient Separation of Hydrogen.

Advancement of a hydrogen economy requires establishment of a whole supply chain including hydrogen production, purification, storage, utilization, and recovery. Nevertheless, it remains challenging to selectively purify hydrogen out of H-containing streams, especially at low concentrations. Herein, a novel protonic ceramic electrochemical cell is reported that can sustainably separate pure H out of H-diluted streams over the temperature regime of 350-500 °C by mildly controlling the electric voltage.

Self-Care and Quality of Life in Elderly Chinese Patients with Benign Prostatic Hyperplasia.

The authors in this study explored the relationship between self-care agency and quality of life in patients with benign prostatic hyperplasia. A convenience sample of 157 patients was interviewed. The levels of both self-care agency and quality of life were close to the mean.
