Using galvanostatic pulse deposition, we studied the factors influencing the quality of electroformed Bi1–xSbx nanowires with respect to composition, crystallinity, and preferred orientation for high thermoelectric performance. Two nonaqueous baths

Vertically aligned, untangled planarized arrays of multiwall carbon nanotubes (MWNTs) with Ohmic back contacts were grown in nanopore templates on arbitrary substrates. The templates were prepared by sputter depositing Nd-doped Al films onto W-coated

The role of Cu-ion doping in α-MnO2 electrocatalysts for the oxygen reduction reaction in alkaline electrolyte was investigated. Cu-doped α-MnO2 nanowires (Cu-α-MnO2) were prepared with varying amounts (up to ∼3%) of Cu2+ using a hydrothermal me

We investigate the structure of $$ \frac{1}{3}\langle 0\bar{1}11\rangle $$ dislocations observed in Bi2Te3 nanowires. This particular type of dislocation is interesting because it has a large Burgers vector (b = 1.048 nm) with a component normal to t

Achieving control of crystalline quality is a key barrier to developing thermoelectric (TE) nanowires. We show that the structural properties of free-standing Bi2(Te.97Se.03)3 nanowire arrays on substrates can be improved by postdeposition annealing.

Electrochemical capacitors based on redox-active metal oxides show great promise for many energy-storage applications. These materials store charge through both electric double-layer charging and faradaic reactions in the oxide. The dimensions of the

Nanoporous carbon (NPC) is a purely graphitic material with highly controlled densities ranging from less than 0.1 to 2.0 g/cm3, grown via pulsed-laser deposition. Decreasing the density of NPC increases the interplanar spacing between graphene-sheet

Magnetite (Fe3O4), ferrihydrite (Fe10O14(OH)2), and iron (Fe) films were electrodeposited by cathodic deposition from an alkaline Fe(III)−triethanolamine solution. The electrodeposited phase depended on the applied potential. Magnetite films were e

Thin films of ceria were electrodeposited onto Hastelloy substrates by the electrochemical oxidation of Ce(III) acetate complexes. The mode of deposition was dependent on the applied potential. At a potential of + 0.5 V vs. Ag/AgCl, the deposition pr
