Construction of Ultrafine PtIr Clusters Supported on CoO Nanoflowers for Enhanced Overall Water Splitting.

Green hydrogen production through electrochemical overall water splitting has suffered from sluggish oxygen evolution reaction (OER) kinetics, inferior conversion efficiency, and high cost. Herein, ultrafine PtIr clusters are synthesized via an electrodeposition method and decorated on the CoO nanoflowers assembled by nanowires (PtIr-CoO). The encouraging performances in electrochemical OER and hydrogen evolution reaction (HER) are achieved over the PtIr-CoO catalyst, with the overpotentials as low as 410 and 237 mV at 100 mA cm, respectively, outperforming the commercial IrO and Pt/C catalysts.

Common complications and prevention strategies for resuscitative endovascular balloon occlusion of the aorta: A narrative review.

Resuscitative endovascular balloon occlusion of the aorta (REBOA) is considered a key measure of treatment due to its use in stabilizing patients in shock through temporary inflow occlusion for noncompressible torso hemorrhage as well as its supportive role in myocardial and cerebral perfusion. Although its clinical efficacy in trauma has been widely recognized, concerns over related complications, such as vascular access and ischemia-reperfusion, are on the rise. This paper aims to investigate complications associated with REBOA and identify current and emerging prevention or mitigation strategies through a literature review based on human or animal data.
