This paper introduces a virtual simulation method of gas diffusion in the Chemical Industry Park(CIP), the CIP scene in 3D was established on the basis of the real terrain. To ammonia leakage and diffusion for example, the process of leakage accident was realized in virtual reality by means of embedded the toxic gas diffusion mathematical model to 3D scene. The whole process of the accident can be...
Single-Walled Carbon Nanotubes(SWNTs) have excellent electrical properties to fabricate field-effect transistor (FET) biosensor, microelectrodes, microelectric unit etc. At present, biosensors based on CNTFET are required in various applications, including clinical diagnostics, environmental testing, food analysis, and bioterrorism detection technologies. But nowadays SWNTs are typically grown as...
Depositing single-walled carbon nanotubes (SWNTs) with controllable density, pattern and orientation on electrodes presents a challenge in today’s research. Here, we report a novel solvent evaporation method to align SWNTs in patterns havingnanoscale width and micronscale length. SWNTs suspension has been introduced dropwise onto photoresist resin microchannels; and the capillary force can stretch...
Due to their unique electrical, geometrical, mechanical and biocompatible properties, single-walled carbon nanotubes (SWNTs) are attractive materials for the construction of nanoscale field-effect transistor (FET) biosensors. At present, biosensors based on CNTFET are required in various applications, including clinical diagnostics, environmental testing, food analysis, and bioterrorism detection...
Precise self-assembly of carbon nanotubes (CNTs) by fluidic shear forces is reported in our paper. The submicrochannel template of (polydimethylsiloxane) PDMS have been manufactured by lithography technology. Using these channels as a guide for leading carbon nanotubes highly oriented. Then the carbon nanotubes can be stretched and aligned parallel to the sub-microchannels. The experimental details...
