Fine gold

Mix 50 pi of fine gold particle suspension successively with donor/acceptor plasmid DNA (up to 10 pg in total), 50 pi of 2.5 M CaCl2, and 20 pi of 0.1 M Spermidine while vortexing. 

The newest electroscope utilizes a quartz fiber and has many advantages over the gold-leaf type. It is portable, less dependent on position, much smaller in size, and more sensitive. The capacity of the quartz fiber electroscope is about 0.2 pico-farads, and its voltage sensitivity is about one volt per division on the scale. The sensitive element is a fine gold plated quartz fiber mounted on a parallel metal support. Figure 22 illustrates a quartz fiber electroscope.

This technology is currently commercially available but is not being used for site remediation. The CCJ is currently being used for fine gold recovery. This technology is protected under U.S. Patents 4,279,741 and 4,998,986.

The separation of hidden gold from every other metal is effected by extraction in aqua regia, for this water attacks to dissolve no other metal than fine gold alone. This is a loose and incorrect statement. 

Sensors for nitrogen dioxide detection use a Au/PVC composite prepared by dispersion of a fine gold powder in a highly plasticised PVC matrix containing a hydrophobic electrolyte (Au/PVC electrode)117 which could be used continuously for monitoring the gaseous environment when the nitrogen dioxide content varied only slowly. 

Take four parts of your Animated Mercury and carefully amalgamate it with one part of fine gold powder in a glass mortar. Wash the amalgam with water until it is clean and shining then blot it dry with a cloth.

Gold prepared by fire and separated from other metals. Fine gold, called by the Greeks,... 

GOLD — Another Dissolvent. Take two ounces of Saltpetre, half an ounce of very dry Saw-dust of Walnut-wood. Reduce the whole into an impalpable powder. Fill a large nut-shell as full as it will hold with this powder, and thereon [that is, upon the powder] place a small plate of fine Gold, so as to cover it completely. Cover the plate with another layer of powder about the thickness of a finger and then you will see by experience that the plate will melt and go down to the bottom of the shell, without the shell being burnt. The same experiment may be made with other metals.
