As the degradation of polymer electrolyte membranes (PEMs) shows catastrophic failures with pinholes and cracks, studies on PEM degradation are essential to improve the reliability and lifetime of polymer electrolyte membrane fuel cell (PEMFC) membra

In this paper, we propose a programmable tap structure used in a programmable FIR digital filter for high-frequency communication system, which speed performance is comparable to the case of a non-programmable filter. A fully parallel bit-level pipel

In this study, we address the catalytic performance of variously sized Pt nanoparticles (NPs) (from 1.7 to 2.9 nm) supported on magnéli phase titanium oxide (MPTO, Ti4O7) along with commercial solid type carbon (VXC-72R) for oxygen reduction reactio
