RECOVERING ACTIVITY OF ANODICALLY CHALLENGED OXYGEN REDUCTION ELECTROCATALYSTS BY MEANS OF REDUCTIVE POTENTIAL PULSES

Recovering activity of anodically challenged oxygen reduction electrocatalysts by means of reductive potential pulses

The stability of electrocatalysts is of great importance to ensure their applicability, but stability is generally only considered for catalysts polarised to a constant potential or current density.This excludes stability evaluation under start/stop conditions in a fuel cell or in reversible batteries in which the catalyst is alternately polarised

Explosive Vomiting Associated with Proximal Colonic Distention during a Difficult Propofol-Assisted Colonoscopy

We present a case of explosive vomiting associated with the extensive manipulation of the proximal colon parad bhasma price during a difficult colonoscopy procedure.The cause of vomiting in this case may have been multifactorial; however, proximal colonic distention was the most likely factor because the onset of vomiting coincided with proximal co
