Extended and oriented nanostructures are desirable for many applications, but direct fabrication of complex nanostructures with controlled crystalline morphology, orientation and surface architectures remains a significant challenge. Here we report a

This paper reports the preparation of cubically ordered, self-assembled nanostructural crystals on micropatterned surfaces. Large ordered arrays of octahedral crystals were formed on substrates with triangular-shaped micropatterns that match the shap

We report for the first time a one-step, templateless method to directly prepare large arrays of oriented TiO2-based nanotubes and continuous films. These titania nanostructures can also be easily prepared as conformal coatings on a substrate. The na
