Electrodeposition and behavior of single metal nanowire probes.

This paper describes the fabrication of scanning probes with single metal nanowires (NWs) at the probe tip. The porous-template technique can produce NWs of various kinds of metals, with diameters down to 10-20 nm, which compete with multiwall carbon nanotube diameters. Metal NWs are grown by electrodeposition on the scanning probe tip.

Nanotubular array solid oxide fuel cell.

This report presents a demonstration and characterization of a nanotubular array of solid oxide fuel cells (SOFCs) made of one-end-closed hollow tube Ni/yttria-stabilized zirconia/Pt membrane electrode assemblies (MEAs). The tubular MEAs are nominally ∼5 μm long and have <500 nm outside diameter with total MEA thickness of nearly 50 nm. Open circuit voltages up to 660 mV (vs air) and power densities up to 1.

A resolution study for electrostatic force microscopy on bimetallic samples using the boundary element method.

Electrostatic force microscopy (EFM) is a special design of non-contact atomic force microscopy used for detecting electrostatic interactions between the probe tip and the sample. Its resolution is limited by the finite probe size and the long-range characteristics of electrostatic forces. Therefore, quantitative analysis is crucial to understanding the relationship between the actual local surface potential distribution and the quantities obtained from EFM measurements.
