WebThe electrorheological (ER) properties of composite materials consisting of a nematic liquid crystal (LC) and gold nanoparticles (GNPs) coated with bistolane-based mesogenic groups were studied. The GNPs were coated by normal alkyl chains and the fluorescent LC compounds, of which the molecular structure was similar to that of the LC matrix. WebMilky Quartz is the most commonly-found form of crystalline quartz. The cloudy "milkiness" of the crystals comes from fluid bubbles trapped inside the structure during formation. Those searching for gold often look for this type of quartz, as it is sometimes associated with gold veins.
