A method for determining the number of layers (NL) or thickness (DGP) of multi-layer graphene (MLG) using X-ray diffraction (XRD) is reported for the first time. The XRD pattern showed clear variations in the full-width-at-half-maximum (FWHM) values of the (0 0 2) peak of crystalline MLG with NL = 3, 4, 5, 6, and 7. The large FWHM difference per layer Cheap Jordans For Sale
and the instant measurement of large areas of MLG demonstrates that XRD is a powerful probe. The obtained linear plot of FWHM versus 1/DGP and the NL-dependent evolution of the interlayer distance (d002) toward the d002 of graphite are also discussed.
This study uses time series analysis to investigate the impact of Hong Kong's increased outward processing trade with Air Jordan 8 Retro the Chinese Mainland on wage inequality. We found a significant positive association between outward processing trade and the wage premium of university graduates over primary school graduates and that over secondary school graduates. Moreover, a standard test showed one-way causality from Cheap Jordans Online Canada
outward processing trade to the widening of skill wage gap. Furthermore, the increase of outward processing trade is found to both increase the pay for well-educated people and decrease the pay for less well-educated people, thereby widening the wage gap.
