...Johnson Samuel; Shiv G. Kapoor; Richard E. DeVor; K. Jimmy Hsia The objective of this paper is to understand through parametric studies the effect of microstructural parameters, viz., the carbon nanotube (CNT) orientation with respect to the cutting direction, CNT loading, and level of dispersion...

... probe (such as a nanotube or a nanowire) to explore deep surface features with high resolution. In practice, however, carbon nanotube and nanowire probes are not always perfectly aligned ( 4 ). Although when these probes are commercially obtained, the nominal deviations from the vertical orientation...

...J. Samuel; A. Dikshit; R. E. DeVor; S. G. Kapoor; K. J. Hsia The machinability of carbon nanotube (CNT)-reinforced polymer composites is studied as a function of CNT loading, in light of the trends seen in their material properties. To this end, the thermomechanical properties of the CNT composites...

...Chun-Hsi Su; Chii-Ruey Lin; Guo-Tsai Liau; Ching-Yu Chang Microwave plasma jet chemical vapor deposition is used to grow array types of carbon nanotubes and diamond films on silicon substrates. In this study, we report a patterned growth of carbon nanotubes and diamond films using the barrier layer...

...A. Dikshit; J. Samuel; R. E. DeVor; S. G. Kapoor The microstructure-level finite element machining model developed in Part I of this paper is used to perform a detailed analysis of the failure mechanisms that occur while machining the carbon nanotube (CNT) reinforced polycarbonate composites...

...A. Dikshit; J. Samuel; R. E. DeVor; S. G. Kapoor A microstructure-level finite element machining model has been developed to simulate the machining of carbon nanotube (CNT) reinforced polymer composites. The model integrates a failure model with a previously developed microstructure-based material...

...Ashutosh Dikshit; Johnson Samuel; Richard E. DeVor; Shiv G. Kapoor A continuum-based microstructure-level material model for simulation of polycarbonate carbon nanotube (CNT) composite machining has been developed wherein polycarbonate and CNT phases are modeled separately. A parametrization scheme...

...J. Samuel; R. E. DeVor; S. G. Kapoor; K. J. Hsia The machinability of a polycarbonate nanocomposite containing multiwalled carbon nanotubes is investigated and contrasted with its base polymer and with a conventional carbon fiber composite. The material microstructures are characterized using...

...Wenping Jiang; Pal Molian; Hans Ferkel Carbon nanotubes were synthesized in an atmospheric chamber by irradiating a metal-catalyst containing graphite target with a 2 kW continuous wave CO 2 laser and capturing the soot in flowing distilled water to facilitate continuous, rapid production...
