Naturally occurring calcium carbonates often have a complex accessory mineralogy. Quartz is a common associate, typically present at concentrations < 1 wt.%. A method is described whereby x-ray powder diffractometry may be used to quantify quartz in such samples to better than f 0.01 wt.% (la error)
## Abstract The inโplane structures of vapor deposited ultrathin films of distyrylโoligothiophenes (DSโ2T) on SiO~2~ substrate were characterized by grazing incidence xโray diffractometry (GIXD). Two polymorphs, lowโtemperature and highโtemperature phases, were identified, and the two dimensional u
