Robust Superhydrophilic/Hydrophobic Surface Based on Self-Aggregated Al<sub>2</sub>O<sub>3</sub> Nanowires by Single-Step Anodization and Self-Assembly Method
Superhydrophilic and superhydrophobic surfaces were studied
with
an eye to industrial applications and use as research tools. Conventional
methods involve complex and time-consuming processes and cannot feasibly
produce large-area three-dimensional surfaces. Here, we report robust
and large-area alumina nanowire structures with superhydrophobic or
superhydrophilic properties, generated by an inexpensive single-step
anodization process that can routinely create arbitrary three-dimensional
shapes. This process is expected to open up diverse applications

Hybrid Energy Cell for Degradation of Methyl Orange by Self-Powered Electrocatalytic Oxidation
In general, methyl orange (MO) can be degraded by an
electrocatalytic oxidation process driven by a power source due to
the generation of superoxidative hydroxyl radical on the anode. Here,
we report a hybrid energy cell that is used for a self-powered electrocatalytic
process for the degradation of MO without using an external power
source. The hybrid energy cell can simultaneously or individually
harvest mechanical and thermal energies. The mechanical energy was
harvested by the triboelectric nanogenerator (TENG) fabricated at
the top by using a flexible polydimethysiloxane (PDMS) nanowire array
with diameters of about 200 nm. A pyroelectric nanogenerator (PENG)
was fabricated below the TENG to harvest thermal energy. The power
output of the device can be directly used for electrodegradation of
MO, demonstrating a self-powered electrocatalytic oxidation process
