Zhichang Liu, then a postdoctoral fellow in Stoddart's lab, was originally trying to make an extended, three-dimensional cubic structure by mixing together two test tubes--one containing alpha-cyclodextrin and the other a dissolved gold salt
. While he thought he would end up with a 3-D structure to store gases and small molecules, Liu really ended up with needles, comprising straw-like bundles of supramolecular wires.
Less common adverse events include allergic reaction, darkening of cosmetic tattoos, immune reaction, and chrysiasis, which is a dark-blue pigmentation caused by Q-switched laser treatment in patients with a history of gold salt
The 16 and 18 gold nanospheres (AuNSs) used as seeds were prepared by a reverse-modified Turkevich method  by citrate reduction of gold salt
. Shortly, in a three-neck round-bottom flask with a condenser mounted, a citrate solution was brought to boiling by a heating mantle for 5 mins; then a gold solution of initial concentration of 25 mM was added, and after a light red ruby color appeared the system was left to react for half hour.
approaches takes a longer time (1 hr) for gold salt

concentrations on the size and polydispersity of gold nanoparticles prepared by an extended Turkevich-Frens method," Gold Bulletin, vol.
These suspensions were prepared under conditions of lowest concentration of gold salt
(systems 1,2, and 3), and sample 9 was obtained at the highest pH value.
One of the team, Zhichang Liu, mixed a sugar named alpha-cyclodextrin, which is derived from cornstarch, with dissolved gold salt
in the hopes of creating some sort of three-dimensional cubic structure.
There were some 30 gold salt
cellars and 14 basins in Henry VIII's Jewel House by 1532, and he also had 36 gold cups (Fig.
In Chapter 1, she uses hydrogen to reduce a gold salt
. She dissolved gold in aqua regia (a solution of nitro-muriatic acid) and then treats this with ether, in which the gold salt
The addition of bulk metallic gold to Aqua Regia dissolves the gold and forms a gold salt
, [AuCl.sub.4]H, a trichloride of gold with one molecule of HCl attached to [AuCl.sub.3].
The table is laden with metal accessories that make an elegant table setting as the brass plate chargers and brass angular napkin rings are offset by gold flatware and gold salt
and pepper shakers.
ABOUT 4 AM ON SUNDAY May 11th, 2003, thieves broke into the Kunsthistorischesmuseum in Vienna and carried off one of the greatest treasures produced by the Italian Renaissance: the gold salt
cellar made by Benvenuto Cellini for the French king, Francis I.
