Miniaturized gas ionization sensors using carbon nanotubes
Article Abstract:
Research describes the fabrication and testing of ionization microsensors capable of breaking down of gases and gas mixtures at carbon nanotube tips. The sensitivity and selectivity of the sensors are not affected by temperature, humidity, and gas flow. These low cost can be deployed for environmental monitoring, as chemical sensors, and as gas detectors in counter-terrorism.

How does a nanofibre grow?
Article Abstract:
The interaction of metal-catalyst nanoparticles with hydrogen vapour at high temperature results in the growth of nanoscale carbon fibres. The nanofibre growth is promoted by the abrupt changes in the catalyst particle, which are driven by the reaction between the catalyst and the vapour.

Oxygen breaks into carbon world
Article Abstract:
The process by which oxygen attacks carbon bonds to break up the atomic structure of graphite is explained. Understanding this process is important as it may lead to a new area of nanotechnology based on nanoscale graphite origami.
