Applicable surface enhanced Raman scattering (SERS) active substrates require high enhancement factor (EF), excellent spatial reproducibility, and low-cost fabrication method on a large area. Although several SERS substrates with high EF and relative standard deviation (RSD) of signal less than 5% were reported, reliable fabrication for large area SERS(More)
Self-supported metallic nanopore arrays with highly oriented nanoporous structures are fabricated and applied as ideally nanostructured electrodes for supercapacitor applications. Their large specific surface area can ensure a high capacitance, and their highly oriented and stable nanoporous structure can facilitate ion transport.
In this paper the Al<sub>2</sub>O<sub>3</sub> nanowire is grown on silicon chips by electrochemical reaction under AFM probe. The obtained Al<sub>2</sub>O<sub>3</sub> nanowire is regular arranged, the length and width of the nanowire can be controlled by adjusting applied voltage and scanning rate of AFM probe
The spatial distribution of localized surface plasmon resonance (LSPR) plays a key role in many plasmonic applications. Based on the thermal stability of alumina templates, this work reports a novel approach to manipulate the distribution of LSPR and exhibits its significance for an important plasmonic application, the surface-enhanced Raman spectroscopy(More)
For the first time, a conductive-substrate induced electro-deposition approach is employed to achieve highly ordered TiO2 nanotube arrays based on an anodic aluminum oxide template. Different from other methods, the morphology and parameters of arrays can be adjusted easily through changing the exposure area of a conductive layer. All these arrays are used(More)
In the present work, solution plasma process (SPP) with bubbling gas was used to prepare oligochitosan. The effect of SPP irradiation with bubbling gas on the degradation of chitosan was evaluated by the intrinsic viscosity reduction rate and the degradation kinetic. The formation of OH radical was studied. Changes of the physicochemical properties of(More)
Plasmonic circuitry is considered as a promising solution-effective technology for miniaturizing and integrating the next generation of optical nano-devices. A key element is the shared metal network between electrical and optical information enabling an efficient hetero-integration of an electronic control layer and a plasmonic data link. Here, we(More)
Despite the strong effects of disturbance on plant community diversity and assembly, we do not fully understand how different aspects of taxonomic or functional diversity respond to disturbance or how different assembly processes change along a disturbance gradient. In this study, plant communities were sampled and the distributions of three functional(More)
The nanowall has been regarded as a promising architecture for highly efficient photoelectrochemical (PEC) water splitting due to various advantages, such as open geometry, highly reactive facets, independent contact with current collector, and so forth. Here, a vertically aligned Bi2MoO6 nanosheet array, which is also called a nanowall, is first achieved(More)
A solution-processed patterning of functional organic materials in emulsion is reported. The concept is to absorb microdrops onto predefined locations by hydrophilicity difference. Owing to a universal solvent used, the method can be applied to pattern variety materials on substrates of interest over large size. The figure shows Rhodamine 6G patterned film.
