Square Pulse Galvanostatic Synthesis and Characterization of Nano- Copper Oxide

International Journal of Electrochemical Science, 2017
In this study, the copper oxide nanoparticles are synthesized by the square pulse galvanostatic method (SPGM) through anodic oxidation of copper electrode in sodium sulfate solution. The released Cu2+ ions are precipitated slowly as Cu(OH)2 nanoparticles.

Engineering Strategies for Stable and Long‐Life Alkaline Zinc‐Based Flow Batteries

Advanced Functional Materials, EarlyView.
Alkaline zinc‐based flow batteries face persistent challenges from unstable zinc deposition, including dendrite growth, passivation, corrosion, and hydrogen evolution, which severely limit cycling stability. Current research addresses these issues through coordinated electrode structuring, electrolyte regulation, and membrane design to control zinc ...

Reliable irogane alloys and niiro patination—further study of production and application to jewelry [PDF]

, 2010
Japanese metalworkers use a wide range of irogane alloys (shakudo, shibuichi), which are colored with a single patination solution (niiro eki). This approach allows different alloys to be combined in one piece and patinated, producing a multi-colored ...
