In this article, we focused on the comprehension of surface reactivity layered β(III)-cobalt oxyhydroxide, β(III)-CoOOH, by implementing a multiscale study associating both experimental, characterization X-ray photoemission spectroscopy (XPS) and scanning electron microscopy first-principles calculations. The chemical properties are key factors in charge-storage mechanism, β(III)-CoOOH presents...

Nickel–cobalt oxyhydroxide has been delaminated by tetrabutylammonium (TBA+) intercalation in aqueous media. The electrochemical performance of the different materials obtained during delamination evaluated, with special emphasis on effect intercalated species and their influence behavior material, toward energy storage applications. Delamination TBAOH, reported for first time nickel–cobalt med...

Combining electrochemical measurements with in situ and ex photoelectron spectroscopy simulations to detect the formation of cobalt oxyhydroxide during oxygen evolution reaction.

Cobalt-doped magnetite (CoxFe3 -xO4) nanoparticles have been produced through the microbial reduction of cobalt-iron oxyhydroxide by the bacterium Geobacter sulfurreducens. The materials produced, as measured by superconducting quantum interference device magnetometry, X-ray magnetic circular dichroism, Mössbauer spectroscopy, etc., show dramatic increases in coercivity with increasing cobalt c...

BACKGROUND Hyperphosphatemia necessitates the use of phosphate binders in most dialysis patients. Long-term efficacy and tolerability of the iron-based phosphate binder, sucroferric oxyhydroxide (previously known as PA21), was compared with that of sevelamer carbonate (sevelamer) in an open-label Phase III extension study. METHODS In the initial Phase III study, hemo- or peritoneal dialysis p...

This study assesses the role of competing ions in the mobilization of arsenic (As) by surface complexation modeling of the temporal variability of As in groundwater. The potential use of two different surface complexation models (SCMs), developed for ferrihydrite and goethite, has been explored to account for the temporal variation of As(III) and As(V) concentration, monitored in shallow ground...

Introduction In this phase III, open-label, single-arm, multi-center 12-week study, we evaluated the efficacy and safety of combination therapy with sucroferric oxyhydroxide (PA21) and calcium carbonate for hemodialysis patients with hyperphosphatemia. Methods We enrolled 35 subjects aged ≥ 20 years with end-stage kidney disease and serum phosphorus 3.5-6.0 mg/dl who were undergoing hemodialy...

Inflammatory Bowel Disease Relief In article number 2214693, Yunjiao Zhang and co-workers demonstrate 2D cobalt oxyhydroxide nanosheets (Co NSs) with excellent multienzyme-like activity as potential inhibitors of NLRP3 inflammasome pyroptosis. Owing to the robust reactive oxygen species scavenging oligomerization inhibiting ability, Co NSs block assembly activation inflammasome, thereby exhibit...
