High-aspect ratio submicrometer needles for intracellular applications

A processing technology is presented to produce high-aspect ratio submicrometer silicon needles suited for intracellular interfacing with living cells. Pillars are created using deep reactive ion etching, and the sharpening of the pillars is achieved by reactive ion etching. A simple polyimide-based micro-fabrication approach was developed to integrate the silicon needles with a larger silicon ...

High power density electrodes for Carbon supercapacitor applications

This paper presents results obtained with 4 cm2 Carbon/Carbon supercapacitors cells in organic electrolyte. In the first approach, a surface treatment for Al current collector foil via the sol–gel route has been used in order to decrease the Al/active material interface resistance. Performances obtained with this original process are: a low equivalent series resistance (ESR) of 0.5 Ω cm2 and a ...

Hydrothermal Synthesis of ZnO Structures Formed by High-Aspect-Ratio Nanowires for Acetone Detection

Snowflake-like ZnO structures originating from self-assembled nanowires were prepared by a low-temperature aqueous solution method. The as-grown hierarchical ZnO structures were investigated by X-ray diffraction (XRD) and field-emission scanning electron microscopy (FESEM). The results showed that the snowflake-like ZnO structures were composed of high-aspect-ratio nanowires. Furthermore, gas-s...
