By confining highly active nanoengineered catalysts into an ultra-thin catalyst layer, a dramatic decrease in Pt usage down to 3 μg·cm–2 is achieved in direct formic acid fuel cell anodes while maintaining impressive electrode activity, durability and power performance in both single cells and multi-cell stacks.

This paper presents the first successful fabrication of well-ordered arrays of vertically-aligned, size- and position-controlled NiSi2/Si heterostructures and single-crystalline NiSi2 nanowires on (001)Si substrates. The obtained fully silicided NiSi2 nanowires array exhibited excellent field-emission properties, and the surface wettability of Si nanowires was found to switch from hydrophobic to hydrophilic after Ni silicidation.

The frequencies of the G and 2D Raman modes of graphene grown on copper undergo red shifts during oxidation of the copper substrate, while the intensities of the two bands increase by more than an order of magnitude.

The contactless dielectric force microscopy and conventional field-effect transistor techniques are employed to probe the intrinsic carrier transport properties on the same single-walled carbon nanotubes for comparison. Quantitative correlation between the methods and a microscopic model clearly demonstrate the parallel between the two methods.

We report a hybrid energy cell that can simultaneously or individually harvest wind, solar, and chemical energies to power some electronic devices. By integrating a triboelectric nanogenerator, a solar cell, and an electrochemical cell, a hybrid energy cell has been fabricated to simultaneously scavenge three different types of energies.
