Electrodeposition of platinum and silver into hydrophobic and hydrophilic microporous silicon layers was investigated using chemically-modified microporous silicon electrodes. Hydrophobic microporous silicon enhanced the electrodeposition of platinum in the porous layer. Meanwhile hydrophilic one showed that platinum was hardly deposited within the porous layer and a filmy growth of platinum on...

Anodic aluminium oxide (AAO) templates for multi-walled carbon nanotube (MWCNT) growth were produced by anodization of aluminium followed by pulse-reverse electrodeposition of cobalt inside the AAO pores. Cobalt functioned as the catalyst for H2/C2H2 chemical vapour deposition (CVD) growth of fairly well graphitized MWCNTs initiating inside the majority of the AAO pores and quickly growing beyo...

Abstract: nanocrystalline nickel samples with the grain size of ~25 nm were prepared via direct current electrodeposition andaluminized for different durations by pack cementation method at 500 means of SEM, EDS and XRD techniques. According to results, short time aluminizing resulted in the formation of asingle aluminide layer whereas at long duration two distinct aluminide layers were formed....

Interfacial deposition stability at the Li-metal-solid electrolyte interface in all solid-state batteries is governed by stress-transport-electrochemistry coupling conjunction with polycrystalline/amorphous solid architecture. In this work, we delineate optimal microstructure comprising grains, grain boundaries, and voids possessing desirable ionic conductivity elastic modulus for superior tran...

In this study, carbon nanotubes were prepared using a pure chemical method modified similar to the Hummers with simple changes in work steps. The then coated and reduced on copper aluminum metals electrodeposition (EDP) for corrosion protection application seawater medium (NaCl 3.5%) at four different temperatures: 20, 30, 40, 50 °C, which studied three electrode potentiostats. All measurements...

Arrays of thermoelectric bismuth telluride (Bi(2)Te(3)) nanowires were grown into porous anodic alumina (PAA) membranes prepared by a two-step anodization. Bi(2)Te(3) nanowire arrays were deposited by galvanostatic, potentiostatic and pulsed electrodeposition from aqueous solution at room temperature. Depending on the electrodeposition method and as a consequence of different growth mechanisms,...

Hydrogen evolution assisted electrodeposition is a new bottom-up technique allowing the fast and simple synthesis of nanometals. Electrochemical dealloying is a top-down approach with the same purpose. In this work, we show that a combination of these two methods in sequence by pulse-reverse electrodeposition can be used to prepare high-surface-area nanostructured metals. Highly porous adherent...

The Zn-Cu battery is plagued with both the problems of Cu2+ migration into the anodic chamber as well as the problem of shape change of zinc electrodes, where both of these processes together have historically prevented this type of battery technology from being rechargeable. We herein propose using a monovalent selective cation exchange membrane (CIEM) that through X-ray diffraction experiment...
