Decoupling Thermodynamic and Kinetic Moisture Instability Reveals a Critical Humidity Threshold for Sodium Thiophosphate Solid Electrolyte

Advanced Energy Materials, EarlyView.
A quantitative exposure‐heat treatment framework identifies a critical humidity threshold (15%RH) and heat treatment temperature (80°C) that governs the recoverability of air‐exposed Na3PS4, revealing the decoupled thermodynamic and kinetic contributions to its moisture stability.

Internal Electric Field‐Guided, Low‐Adsorption Ferroelectric Anode Protective Layers for Sustainable Suppression of Polysulfide Side Reactions in Lithium–Sulfur Batteries

Advanced Energy Materials, EarlyView.
A positively polarized ferroelectric β‐pvdf layer incorporating fluorinated boron nitride nanosheets (PPFBN) establishes a strong internal field that promotes Li+ transport toward the anode while suppressing the migration of polysulfide anions. In addition, its intrinsically low polysulfide affinity helps preserve protective‐layer functionality ...

Diffusion in aqueous copper sulfate and copper sulfate-sulfuric acid solutions

Journal of Solution Chemistry, 1987
Diffusion coefficients of copper sulfate-water and copper sulfate-sulfuric acid-water solutions have been determined at 25°C using conductimetric and diaphragm-cell techniques. The ternary diffusion measurements indicate that diffusion of sulfuric acid can produce large counterflows of copper sulfate and vice versa.

Copper Sulfate

The American Journal of Forensic Medicine and Pathology, 1988
We report a case of fatal copper sulfate poisoning of a 30-year-old woman following treatment by an iNyanga ("witch-doctor"). The patient died 2 days later, having lapsed into a coma. Postmortem examination revealed that the patient had died of aspiration pneumonia.

Acute copper sulfate poisoning

The American Journal of Medicine, 1965
Abstract Acute copper sulfate poisoning constituted 33.6 per cent of all cases of poisoning admitted to the Irwin Hospital, New Delhi, in 1961. The highest incidence was found in the hospitals of Delhi and Uttar Pradesh. Forty-eight cases of acute copper sulfate poisoning were studied, with special reference to clinical features and for evidence of ...

A novel purification method for copper sulfate using ethanol

Hydrometallurgy, 2011
This work presents a method for the purification of technical-grade copper sulfate by precipitation with ethanol. We demonstrate a selective separation to the desired purity level, leaving impurities in solution.

A Fatal Copper Sulfate Poisoning

Journal of Analytical Toxicology, 1991
An 11-year-old female died within hours of accidentally ingesting a solution of copper sulfate. A postmortem blood sample was found to contain 66 micrograms/mL copper. The initial qualitative identification of this poison in the body organs and fluids was by means of SEM-microprobe analysis (SEM-MPA) and X-ray fluorescence (XRF).

Effect of copper sulfate on experimental atherosclerosis

Biological Trace Element Research, 1993
Serum copper concentration increases significantly (p < 0.01) in rats with experimental atherosclerosis compared to a control group. The serum zinc, the zinc, and copper concentration in abdominal aorta and in liver decreases significantly (p < 0.05) compared to the control group.
