Nanostructured ultrathin films of pendant carbazole-modified polyelectrolytes were fabricated using the layer-by-layer deposition technique in order to correlate the importance of highly ordered structures and well-defined layer composition in electrochemical cross-linking and nanopatterning. Both UV-vis and surface plasmon resonance (SPR) spectroscopy studies indicated differences in the film ...

A graphene-based carbon ionic liquid electrode modified with gold nanoparticles was fabricated. The electrochemical response of the modified electrode toward celecoxib was studied by means of cyclic voltammetry and differential pulse voltammetry. The structural morphology of the modified electrode was characterized by a scanning electron microscopy technique and electrochemical impedance spectr...

An approach has been developed to produce silver nanoparticles (AgNPs) rapidly on semiconductor wafers using electrochemical deposition. The closely packed AgNPs have a density of up to 1.4 × 1011 cm-2 with good size uniformity. AgNPs retain their shape and position on the substrate when used as nanomasks for producing ultrahigh-density vertical nanowire arrays with controllable size, making it...

Hybrid organic / inorganic films, composed of poly 4-aminoquinolidine (PAQ) matrix and Prussian blue – like copper hexacyanoferrate (CuHCFe) redox centers were prepared. Platinum disk (Pt) was used as a conductive substrate onto which the hybrid films (Pt/PAQ/CuHCFe) were electrodeposited by potential cycling. Electrochemical behavior of the modified electrode was well characterized using cycli...

The properties of fully complementary metal-oxide semiconductor (CMOS)-compatible metal-coated nanostructured silicon anodes for Li-ion microbatteries have been studied. The one-dimensional nanowires on black silicon (nb-Si) were prepared by inductively coupled plasma (ICP) etching and the metal (Au and Cu) coatings by successive magnetron sputtering technique. The Cu-coated nb-Si show the most...

We present a new method for developing hydrogen silsesquioxane (HSQ) by using electrical potentials and deionized water. Nested-L test structures with a pitch as small as 9 nm were developed using this electrochemical technique in saline solution without adding hydroxyl ions. Furthermore, we showed that high-resolution structures can be electrochemically developed in deionized water alone. Elec...
