Recovery of copper from spent catalyst using acid leaching followed by electrodeposition on square rotating cylinder

Alexandria Engineering Journal, 2018
In this study, the kinetics of acid leaching of a spent catalyst containing CuO was investigated. The effect of key parameters such as type of acid (H2SO4, HCl, Oxalic acid), concentration of acid (0.5–2 M), stirring speed (200–600 rpm), liquid to solid ...

Study on the Reaction Mechanism of RuOx and Its Enhanced Hydrogen Evolution Reaction Activity

Advanced Science, EarlyView.
In situ Raman spectroscopy and DFT calculations reveal that, prior to the onset of HER, the surface of RuOx undergoes reversible reduction and structural reconstruction. The resulting Ru(II)O/Ru(IV)O2 configuration is identified as the true catalytically active species.

From Magnetic Fibers to Paper Architectures: A Lightweight Strategy for Robust Low‐Frequency Microwave Absorption

Advanced Science, EarlyView.
A scalable process converts para‐aramid fibers into soft‐magnetic building blocks via micrometer‐thick Fe0.64Ni0.36 (Invar‐type) coatings. Assembled into paper, they form a hierarchical conductive network whose tunable permeability enables thin, lightweight microwave absorption in the low‐frequency (S‐band) regime.

Chelation‐Driven Dual‐Interface Regulation for Long‐Life Aqueous Zn–I2 Batteries

Advanced Science, EarlyView.
Zn2+–TPEN coordination generates TPEN‐derived coordination species (TCC) that contribute to the regulation of both electrode interfaces. At the Zn anode, it creates an interfacial environment with reduced water accessibility that suppresses HER and corrosion while promoting uniform deposition; at the I2 cathode, it captures polyiodide to inhibit ...

A Scalable Spin‐Coating Strategy for Mesoporous Gold Thin Films toward miRNA Detection

Advanced Science, EarlyView.
A scalable spin‐coating strategy produces uniform mesoporous Au thin films with tunable thickness and high electroactive surface area on transparent substrates. The resulting architecture enables label‐free, amplification‐free detection of ovarian cancer‐associated miRNA hsa‐miR‐200c‐3p from 1 aM to 10 pM, achieving a 1.72 aM detection limit with high ...

Microfabrication of conductive copper patterns by meniscus-confined electrodeposition

, 2018
Complex three-dimensional copper (Cu) wires have been successfully fabricated by meniscus-confined electrodeposition (MCED) controlled by quasi-static stability of the meniscus. Here, we report a new dynamic meniscus stability based MCED process.
