In nature, mercury (Hg) occurs in the elemental form (Hg 0 ), as well as in inorganic (InHg) and organic (OrgHg) compounds. It is the only heavy metal that is liquid at room temperature and easily turns into a gas. Mercury vapours can be transported with air masses for hundreds and...
英英释义 Mercury(Hg) n. a heavy silvery toxic univalent and bivalent metallic element; the only metal that is liquid at ordinary temperatures 同义词:quicksilverhydrargyrumHgatomic number 80 (Roman mythology) messenger of Jupiter and god of commerce; counterpart of Greek Hermes ...
It is a dense, silvery-white liquid at room temperature. The symbol Hg of mercury comes from its Latin name hydrargyrum, meaning liquid silver. Mercury is named after the Roman god Mercury, who was known as the messenger of the gods. ...
The molecules display interesting and intense luminescence properties at room temperature. The present investigation clearly demonstrates that attractive mercurophilic interactions do play an essential role in bringing two porphyrin macrocycles exactly on top of each other with an unfavorable fully eclipsed ...
vapour pressure even at room temperature, its vapour must also be soluble in water. There is, however, no difference between a solution of liquid and one of vaporous mercury, since in the case of a solution only the existing state is of importance and not the former states of its componen...

The fabrication of the first MESFET structures on Hg/sub 1-x/Cd/sub x/Te is reported using MOCVD grown layers on GaAs substrates. The 6 mu m gate devices exhibited a room temperature transconductance of 1.0 mS/mm and pinch off voltage of... PW Leech,PJ Gwynn - 《Electronics Letters》 ...
Crystal structures of the elements at 25°C a) These elements are gaseous, or liquid, at room temperature. The structural data for Ar, H, Kr, Ne and Xe refer to 4.2 K, whereas that for Br, C1, He, Hg, N and O refer to123 K, 113 K, 1.5 K, 225 K, 20 Kand23 K, respectiv...
Avoid repeated freeze/thaw cycles. The lyophilized antibody is stable at room temperature for at least one month and for greater than a year when kept at -20°C. When reconstituted in sterile pH 7.4 0.01M PBS or diluent of antibody the antibody is stable for at least two weeks at 2-4 ...
Annealing effects on CdTe crystals in liquid mercury at temperatures ranging from RT to 300°C for 200 h have been investigated by means of photoluminescence characteristics at 4.2 K. The photoluminescence spectra of as-grown p-type CdTe samples by the Bridgman method exhibit a strong broad emissi...
