The article comments on trends and developments within the nanotechnology industry as of 2006. The development of a low-cost technique for mineral analysis that could replace x-ray diffraction, also known as XRD is among those technological developments in the industry. Since it is difficult to determine the relative percentage of various minerals commonly found in petroleum reservoirs, transmission spectroscopy was used so a very small amount of rock, was mixed with potassium bromide to produce the pellets for analysis.
