A facile and highly efficient method for the fabrication of free-standing three-dimensional (3D) composites with different morphologies was designed by the combination of the electrospinning method and hydrothermal reaction. The controlled hierarchical nanoarrays showed excellent electrochemical performance for their potential use as supercapacitor electrodes.

The aim of this paper is to review some of the economic drivers of large scale bioregionalisation, using examples from deep sea hydrothermal vent communities, the Antarctic and sub-Antarctic, and Australia. These economic drivers are mainly recent conservation efforts, while early 20th century bioregionalisation was driven by 19th century taxonomy and exploration to assess available biological ...

zinc oxide nanotubes were prepared by a hydrothermal method using zinc nitrate as a precursor. The synthesized nanotubes were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), Transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FT-IR) and their optical properties were characterized using UV -visible spectroscopy. The XRD analysis confirme...
