Crack-free thick ordered mesoporous TiO2 films with excellent optical quality have been synthesized by combination of “Doctor Blade” technique and a two-step evaporation induced self-assembly (EISA) method. By employing the as-synthesized mesopor

Self-organized nanotube arrays of TiO2 have been grown from titanium (Ti) thin films deposited on p-type Si(100) substrates. Structural and morphological characterizations carried out by X-ray diffraction and scanning electron microcopy indicate that

A pressure-gradient-driven flow inside nanofluidic channels that have a surface charge can be used to generate streaming current and potential. This process forms the basis for electro-chemo-mechanical energy conversion in nanofluidic batteries. Here

We develop a model of a fuel cell stack focused on effects due to current-free spots in the individual cells. The spots disturb potential of the bipolar plate over the distance, which exceeds the physical size of the spot. The variation of plate pote

An organic bilayer composed of metal-free phthalocyanine (p-type semiconductor) and fullerene (n-type semiconductor) was found to be a novel photocathode working in the water phase, in which the interface of fullerene/water efficiently induced the ph
