Mapping carbon nanotube orientation by fast fourier transform of scanning electron micrographs
A novel method of applying a two-dimensional Fourier transform (2D-FFT) to SEM was developed to map the CNT orientation in pre-formed arrays. Local 2D-FFTs were integrated azimuthally to determine an orientation distribution function and the associated Herman parameter. This approach provides data rapidly and over a wide range of lengthscales. Although likely to be applicable to a wide range of anisotropic nanoscale structures, the method was specifically developed to study CNT veils, a system in which orientation critically controls mechanical properties. Using this system as a model, key parameters for the 2D-FFT analysis were optimised, including magnification and domain size; a model set of CNT veils were pre-strained to 5%, 10% and 15%, to vary the alignment degree. The algorithm confirmed a narrower orientation distribution function and increasing Herman parameter, with increasing pre-strain. To validate the algorithm, the local orientation was compared to that derived from a common polarised Raman spectroscopy. Orientation maps of the Herman parameter, derived by both methods, showed good agreement. Quantitatively, the mean Herman parameter calculated using the polarised Raman spectroscopy was 0.42 ± 0.004 compared to 0.32 ± 0.002 for the 2D-FFT method, with a correlation coefficient of 0.73. Possible reasons for the modest and systematic discrepancy were discussed
Character and Community: Rispetto as a Virtue in the Tradition of Italian-American Lawyers
Our project is to contemplate a discrete piece of applied ethics in the American legal profession, a piece of what one might call Italian-American legal ethics. We propose to describe a moral value for which we will use the Italian word rispetto. Our understanding of rispetto is that it is a virtue, a good habit, through which the person learns, practices, teaches, and remembers his place within the family. We will argue here that the practice of this virtue will allow a modern lawyer to be in and of his or her civic and professional community without loss of dignity and a sense of self
