The validity of a simple chronoamperometric technique for measuring the electrophoretic mobilities of colloid particles has been established by comparison of the results with those obtained from photon correlation spectroscopy, a well established method. Resolution of several flaws in the theory underlying chronoamperometric electrophoresis has led to a rationale of electrophoretic deposition b...

Developing highly efficient low-cost electrocatalysts for both hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) in alkaline electrolyte is essential to advance water electrolysis technology. Herein, Ni(OH)2 nanoplates aligned on NiAl foil (Ni(OH)2/NiAl) are developed by simply dealloying NiAl foil in KOH, which exhibits high electrocatalytic activity for OER with a small ov...

Electrodeposition is an important approach that can produce functional compound materials by assembling multiple species at the electrode surface. However, a fundamental understanding of the electrodeposition mechanism has been limited by its complexity and is often gained only through ex situ studies of deposited materials. Here we report on the application of scanning electrochemical microsco...

Long channel lateral programmable metallization cell (PMC) devices, in which a metal electrodeposit is formed on solid electrolyte between two coplanar electrodes several microns apart, have variety of applications beyond standard microelectronics. Whereas fast growth over considerable distances can be achieved using high ion mobility chalcogenide electrolytes, the use more foundry-friendly mat...

Zinc was electrodeposited from an acidic sulphate solution on commercial steel sheet substrates galvanostatically at 10, 20, and 100 mA/cm2. The steel substrates had an average roughness number of 1.34 microns and a high percentage of its grains had their (111) planes parallel to the plate surface. During electrodeposition at 10 mA/cm2, on some specimens, there was an intense potential fluctuat...

The controlled growth of surface-modifying polymer films by electrodeposition often fails because the lack redox activity these compounds. Here, electroactive complexants help to electrodeposit non-electroactive polymers. Hence, we investigate counterion-induced polyelectrolytes: three quaternized poly(N,N-dialkylaminoethyl methacrylate)s (qPDAAEMA), in particular their methyl, ethyl, and isopr...

In the present work, a novel biopolymer approach has been made to electrodeposit manganese dioxide from manganese sulphate in a sulphuric acid bath containing chitosan in the absence and presence of glutaraldehyde as a cross-linking agent. Galvanostatically synthesised electrolytic manganese dioxide (EMD) nanoflakes were used as electrode materials and their electrochemical properties with the ...
