Abstract Zinc is recently gaining interest in the battery community as potential alternative anode material, because of its large natural abundance and potentially larger volumetric density than graphite. Nevertheless, pure Zn anodes have shown so far very poor cycling performance. Here, electrochemical performance Zn‐rich porous Cu–Zn alloys electrodeposited by an environmentally friendly (aqueous) dynamic hydrogen bubble template method reported. The lithiation/delithiation mechanism...
Compact and porous Cu-Zn alloys were electrodeposited from citrate baths. The latter deposits, consisting of a spongy material with macroscopic interconnected porosity (pore diameter tens microns), obtained at large current densities (−3 A cm−2) causing strong hydrogen evolution. Porous deposits compositions between Cu62Zn38 Cu91Zn9 by varying the ions concentrations in deposition baths, optimal morphology for Cu70Zn30 composition. lattice parameter samples, estimated XRD data, showed...
Cu-Ni alloy layers with a bimodal porosity – spongy material made of submicron dendrites, featuring macroscopic pores tens microns large can be deposited from baths containing the metal ions, sodium citrate and ammonium sulfate, using current densities (−3 A cm−2) producing vigorous hydrogen evolution. Alloys broad range compositions are obtained different Cu(II)/Ni(II) concentration ratios. Voltammetric experiments nitrate reduction at compact porous RDEs show, in latter case, lower...
Abstract Compact Ni−Rh alloys are electrodeposited potentiostatically on rotating disk and sheet electrodes; film compositions adjusted by varying bath composition deposition potential E dep . SEM images of these show a compact, globular morphology for Rh contents up to 30 at%, smoother aspect films with medium‐to‐high content Rh. XRD spectra the formation single crystalline phase, diffraction peaks in intermediate positions between those constituent elements. Data analysis indicates that...
The Divertor Tokamak Test (DTT) vacuum vessel (VV) is a toroidal chamber that ensures an enclosed environment for the plasma, confinement barrier, and temperature control. Water flows in double-shell D-shaped VV cross-sectional structure made from stainless steel to operate at set temperature. Beyond control, water cooling circuit needs act as neutron shielding media protect structures installed outside of VV, namely, superconducting coils. function achieved due addition boric acid water....
