Spectrophotometric determination of trace oxalic acid with zirconium(IV)-dibromochloroarsenazo complex

Bulletin of the Chemical Society of Ethiopia, 2007
Based on the property that oxalic acid has the effect on the replacement of dibromochloroarsenazo in zirconium(IV)-dibromochloroarsenazo complex to produce hyperchromic effects in 1.26 M hydrochloric acid medium, a novel method for the determination of ...

Dietary intake of oxalic acid affects plasma oxalic acid concentration in patients with kidney failure [PDF]

Background & aims: Hyperoxaluria may cause kidney stones, kidney function decline and eventually kidney (transplant) failure. High plasma concentrations may lead to systemic oxalosis.

Electrically Tuning Electromagnetic Wave Shielding in Phase Engineered 1T/2H‐MoS2‐Based Devices

Advanced Electronic Materials, EarlyView.
Sub‐millimeter‐thick phase‐engineered 1T/2H‐MoS2 structures enable electrically tunable electromagnetic interference shielding through active modulation of microwave absorption and reflection. The coexistence of metallic and semiconducting phases, combined with a PVA/KOH gel electrolyte, provides dynamic control over charge transport and interfacial ...

A Closed‐Loop Direct Recycling Process for Prussian White From Scrap and End‐of‐Life Sodium‐Ion Batteries

Advanced Energy Materials, EarlyView.
A closed‐loop direct recycling route for Prussian White sodium‐ion battery cathodes is demonstrated. Ice‐stripped scrap and end‐of‐life electrodes are regenerated via low‐temperature aqueous resodiation (80°C), restoring sodium content, Fe2+ redox chemistry, and structural integrity.

Modeling the adsorption of weak organic acids on goethite : the ligand and charge distribution model [PDF]

, 2001
A detailed study is presented in which the CD-MUSIC modeling approach is used in a new modeling approach that can describe the binding of large organic molecules by metal (hydr)oxides taking the full speciation of the adsorbed molecule into account ...

Surface‐Functionalized MXene for Enhanced Photocatalytic CO2 Reduction

Advanced Energy Materials, EarlyView.
Poly(catechol/p‐cresol)‐functionalized MXene (f‐MXene) enhances oxidation stability while preserving conductivity, enabling efficient interfacial electron transfer in a Cu/f‐MXene/reduced TiO2 photocatalyst. Strong Cu–f‐MXene synergy promotes CO2 activation and selective CH4 production, achieving a CH4 yield of 18.1 µmol g−1 (>200 × vs.

Hydrogen migration in oxalic acid di-hydrate at high pressure?

, 2009
Single crystal X-ray diffraction of oxalic acid dihydrate H 2C2O4·2H2O (1), at pressures up to 5.3 GPa, shows significant changes in the molecular geometries, probably accompanied by a proton migration from H2C2O4 to H2O and formation of ionic species ...

Anodic Oxidation of Oxalic Acid on Gold

, 1971
The anodic oxidation of oxalic acid on Au has been studied at 80°C in aqueous media. The reaction rate was measured as a function of potential, oxalic acid concentration, pH, and temperature in H 2SO 4 + K 2SO 4 + KOH solutions of unit ionic strength ...
