Three-dimensional network of coaxial carbon nanotube/manganese oxides electrode for supercapacitors

This three-dimensional network of carbon nanotube structure is served as a stable and conductive framework for controlled electrochemical deposition of MnOx and provides sufficient voids for fast ionic transport during charging/discharging.

Novel synthesis of dual-suspended architectures between Si-pillars for enhanced photocatalytic performance

The dual-suspended architectures, consisting of CNT networks penetrating through cuprous oxides with (quasi-)octahedron structures, are constructed between Si pillars, which show excellent photocatalytic abilities towards MB dye decomposition.

Performance Characteristics of Bio-Inspired Metal Nanostructures as Surface-Enhanced Raman Scattered (SERS) Substrates

The fabrication of high-performance plasmonic nanomaterials for bio-sensing and trace chemical detection is a field of intense theoretical and experimental research. The use of metal-silicon nanopillar arrays as analytical sensors has been reported with reasonable results in recent years. The use of bio-inspired nanocomposite structures that follow the Fibonacci numerical architecture offers the opportunity to develop nanostructures with theoretically higher and more reproducible plasmonic fields over extended areas. The work presented here describes the nanofabrication process for a series of 40 µm × 40 µm bio-inspired arrays classified as asymmetric fractals (sunflower seeds and romanesco broccoli), bilaterally symmetric (acacia leaves and honeycombs), and radially symmetric (such as orchids and lily flowers) using electron beam lithography. In addition, analytical capabilities were evaluated using surface-enhanced Raman scattering (SERS). The substrate characterization and SERS performance of the developed substrates as the strategies to assess the design performance are presented and discussed.
