Performance Dependence Of Thermosyphon On The Functionalization Approaches: An Experimental Study On Thermo-Physical Properties Of Graphene Nanoplatelet-Based Water Nanofluids
Faculty of Engineering University of Malaya
Graphene Nanoplatelets (GNP) were stably dispersed in aqueous media by covalent and non-covalent functionalization. Covalent functionalization was performed by a rapid microwave-assisted approach. Surface functionality groups and morphology of acid-treated GNP were analyzed by Fourier transform infrared spectroscopy and transmission electron microscopy. The GNP-based water nanofluids were then prepared with different concentrations of GNP to evaluate the thermo-physical and rheological properties. It was found that the rheological and thermo-physical properties of all treated samples were significantly enhanced compared to the pure water. The amount of enhancement also increased as the weight concentration increased. Thermo-physical results also confirmed that the thermal …

Innovative Research Publications IRP India
A detailed review on the Carbon Nanotube Filed Effect Transistors (CNTFETs) has been given. A little description about what are carbon nanotubes is also been covered. Various simulation results have also been included in this paper in order to provide better understanding about the carbon nanotubes field effect transistors.Characteristic Graphs of a C-CNTFET with n=10. m=11 (diameter=1.4246 nm) have been studied. Threshold voltage of CNTFETs vs n (for m=0) is also simulated. Equivalent high-frequency small-signal circuit model for a Nanotube transistor has also been analyzed. Also current voltage relationship of the CNTFET with respect to gate oxide thickness and dielectric …
