Uncontrolled crystal growth during electroreduction of reactive metals in liquid electrolytes produces mossy metal deposits. Here, we use electroanalytical rotating disk electrode (RDE) studies to elucidate the origin moss-like electrodeposition metals. Competing Faradaic reactions on surface are shown be source phenomenon. A regime can accessed by subtle shifts electrolyte chemistry and deposi...

We describe a simple way to create patterns of ‘‘soft’’ biomolecular nanostructures such as vesicles on ‘‘hard’’ surfaces such as gold. The key to our approach is the use of an amphiphilic biopolymer as an ‘‘interconnect’’ or tether. The polymer is hydrophobically modified chitosan (hm-chitosan), which is obtained by covalently attaching alkyl tails to the backbone of chitosan. We electrodeposi...

Certain metals can be added to thin films of chalcogenide glasses by photodissolution to create materials with unique morphology and properties. When Ag is combined in this fashion with Ge–Se or Ge–S glasses, the resulting ternary contains a dispersed nanocrystalline Ag2S(e) phase that has large quantities of mobile metal ions. The presence of these ions allows the ternaries to act as solid ele...

The electrochemical deposition of Cu into 0.12 cm and 60 μm thick, highly porous 65 vol % Ni/yttriastabilized zirconia (YSZ) cermets was investigated. An electrochemical cell in which the electrolyte solution was allowed to flow through a porous Ni/YSZ substrate was used to eliminate mass-transfer limitations and to determine the conditions for which the potential drop in the electrolyte soluti...

Vanadium has long been used as a corrosion-resistant coating, including metal alloy for battery cathodes. However, batteries discovered with non-smooth cathode surfaces due to the fabrication process have short life. So, coating stage is required via electroplating method under influence of magnetic field or Magneto Electro Deposition (MED). Knowing limiting current in MED very important becaus...

In this study we report, for the first time, a thick β-W film with mirror-like surface prepared through electrodeposition involving CsF–CsCl eutectic melt combined 2.0 mol% of WO3 at 773 K. A smooth-surfaced thickness 13 µm was obtained when galvanostatic electrolysis performed − 4 mA cm−2. X-ray diffraction analysis revealed that films have strong preferred orientation along {1 1 1} plane, whi...

Advances in thin-film fabrication are integral to enhancing the power of microelectronics while fabrication methods that allow the integration of biological molecules are enabling advances in bioelectronics. A thin-filmfabrication method that further extends the integration of biology with microelectronics by allowing living biological systems to be assembled, cultured, and analyzed on-chip wit...

The absorption and emission spectra, excited-state lifetimes, quantum yields, and electrochemical measurements have been obtained for a new series of chiral complexes based on three different chiral 2,2':6',2' '-terpyridine ligands, (-)-ctpy, (-)-[ctpy-x-ctpy], and (-)-[ctpy-b-ctpy], with one, two, or multiple Ru metal centers. The room-temperature absorption and emission maxima of [[((-)-ctpy)...

A novel low-cost nanoring array fabrication method that combines the process of lithographically patterned nanoscale electrodeposition (LPNE) with colloidal lithography is described. Nanoring array fabrication was accomplished in three steps: (i) a thin (70 nm) sacrificial nickel or silver film was first vapor-deposited onto a plasma-etched packed colloidal monolayer; (ii) the polymer colloids ...
