Surface modification of microelectrodes is a central step in the development of microsensors and microsensor arrays. Here, we present an electrodeposition scheme based on voltage pulses. Key features of this method are uniformity in the deposited electrode coatings, flexibility in the overall deposition area, i.e., the sizes and number of the electrodes to be coated, and precise control of the ...

Rapid and reproducible assembly of aligned nanostructures on a wafer-scale is a crucial, yet one of the most challenging tasks in the incorporation of nanowires into integrated circuits. We present the synthesis of a periodic nanochannel template designed for electrochemical growth of perfectly aligned, rectangular nanowires over large areas. The nanowires can be electrically contacted and char...

We present evidence that in a very thin regime the magnetic layers become discrete islands and superparamagnetic in multilayered CoNi 1–17 nm /Cu 4.2 nm nanowires grown by pulsed electrodeposition using a hole pattern of anodized alumina templates. Magnetic hysteresis loops measured at room temperature using a vibrating sample magnetometer show that superparamagnetism appears at t CoNi 1.7 nm, ...

Textured ferromagnetic Fe nanowire arrays were electrodeposited using a rectangular-pulsed potential deposition technique into anodized aluminum oxide nanochannels. During the electrodeposition of Fe nanowire arrays at a cathodic potential of - 1.2 V, the growth rate of the nanowires was ca. 200 nm s-1. The aspect ratio of Fe nanowires with a diameter of 30 ± 5 nm reached ca. 2000. The long axi...

A new CFRP-aluminum joining method has been developed by Cu electrodeposition. deposition was filled into the roughened CFRP surface and significant anchor effect attained method. As a result, A6061 Al alloy were successfully joined electrodeposition high strength of 67 MPa obtained.

Traditionally, electroplating has involved the continuous deposition of a single layer metal at constant current. However, electrodeposition alternate layers can offer benefits such as reduced wear, improved corrosion resistance and higher tensile strength. The involve different morphology or thickness metal, metals alloy composition with without included particles. In case bath, electrocrystal...

From previous experiments, it was determined that nickel was able to coat boron fiber, however this was done unevenly, with cracks characterizing the coating. This was where it was hypothesized that the boron fiber crossed the interface of the nickel electrolyte solution during electrodeposition. This was different than the coating at the middle, which was all under the electrolyte solution, an...

gd2o3 nanoparticles were prepared by a two–step process; cathodic electrodeposition followed by heat-treatment method. first, gd(oh)3 nanoparticles was galvanostatically deposited from nitrate bath on the steel substrate by pulse current (pc) mode. the deposition experiments was conducted at a typical on-time and off-time (ton=1ms and toff=1ms) for 60 min. the electrodeposited precursor was the...
