Abstract Although anion exchange membrane water electrolyzer (AEMWE) is an emerging device in the green hydrogen production industry, use of alkaline electrolyte tackles practicality due to issues lowering system efficiency and environmental impacts. State‐of‐the‐art technology using pure as advancing overcome current challenges AEMWE. In particular, development this requires a comprehensive evaluation techno‐economic aspects, aiming balance innovation with cost considerations. This involves...
Abstract The state-of-the-art anion-exchange membrane water electrolyzers (AEMWEs) require highly stable electrodes for prolonged operation. stability of the electrode is closely linked to effective evacuation H 2 or O gas generated from surface during electrolysis. In this study, we prepared a super-hydrophilic by depositing porous nickel–iron nanoparticles on annealed TiO nanotubes (NiFe/ATNT) rapid outgassing such nonpolar gases. NiFe/ATNT exhibited an overpotential 235 mV at 10 mA cm −2...
Abstract Oxidation studies of Co–Cr–Cu–Fe–Ni–Si X=(0,0.3,0.6,0.9) high entropy alloys (HEA) at 600, 700 and 800 °C for 30 h are performed in the present work. Isothermal oxidation confirmed that resistance X=(0,0.3,0.6,0.9 ) alloy increases with Silicon (Si) content up to 0.6%, beyond it decreases. rate kinetics study all three designated test temperature represented typical cubic curve. X-ray diffraction (XRD) analysis revealed evolution Cu oxide (CuO) along existing phases HEA samples....
Room temperature ionic liquids (RTILs) have been considered an interesting alternative to stabilizers in platinum (Pt) nanoparticle synthesis because they can prevent agglomeration of nanoparticles and act as a reaction medium. In addition, since RTILs remain liquid state over wide range temperatures, Pt catalyst processing steps, such heat treatments surface cleaning, be omitted, the are uniformly dispersed under fuel cell operating conditions. Herein, we summarize significant works on...
Abstract The current study investigated the effect of density and plating time on structure properties Ni–W coating obtained by direct electro-codeposition from a new deposition bath. Phase formation microstructural changes alloy coatings were analysed X-ray diffraction scanning electron microscopy, respectively. Hardness wear studies revealed better surface-mechanical with increasing or due to higher W content fine structure. values ranged 346 Hv 770 60 mA · cm −2 , min showed highest...
Parkinson's disease (PD) management seeks to balance the benefits and harms of current medications evolves as progresses. The natural history PD associated patterns treatment change were analyzed identify unmet needs in symptoms.Medical charts patients from clinics across US diagnosed on or before June 30th, 2014 retrospectively reviewed. Index date was first clinic visit, post-index period through study end (June 2019). Outcomes included frequency therapy changes period, reasons for change,...
