Enhanced generation of VUV radiation by four-wave mixing in mercury using pulsed laser vaporization
The efficiency of a coherent VUV source at 125 nm, based on 2-photon resonant four-wave mixing in mercury vapor, has been enhanced by up to 2 orders of magnitude. This enhancement was obtained by locally heating a liquid Hg surface with a pulsed excimer laser, resulting in a high density vapor plume in which the nonlinear interaction occurred. Energies up to 5 μJ (1 kW peak power) have been ach...
متن کاملVolatilization of mercury under acidic conditions from mercury-polluted soil by a mercury-resistant Acidithiobacillus ferrooxidans SUG 2-2.
Volatilization of mercury under acidic conditions from soil polluted with mercuric chloride (1.5 mg Hg/kg soil) was studied with resting cells of a mercury-resistant strain, Acidithiobacillus ferrooxidans SUG 2-2. When resting cells of SUG 2-2 (0.01 mg of protein) were incubated for 10 d at 30 degrees C in 20 ml of 1.6 mM sulfuric acid (pH 2.5) with ferrous sulfate (3%) and mercury-polluted soi...
متن کاملVaporization Waves in Metals
The vaporization wave hypothesis Is discussed and Its merits and defects are examined. The vaporizing model is visualized on thermodynamic grounds as carrying the liquid metal through a continuous succession of states either on or near the liquidus line in the two-phase region. On this line the adiabatic sound speed for wet vapor will limit the rate of propagation of the vaporization front into...
متن کاملDielectric barrier discharge-plasma induced vaporization and its application to the determination of mercury by atomic fluorescence spectrometry.
This paper describes a low-temperature dielectric barrier discharge (DBD)-plasma induced vaporization technique using mercury as a model analyte. The evaporation and atomization of dissolved mercury species in the sample solution can be achieved rapidly in one step, allowing mercury to be directly detected by atomic fluorescence spectrometry. The DBD plasma was generated concentrically in-betwe...
متن کاملDichlorido(di-2-pyridylamine)mercury(II)
In the mol-ecule of the title compound, [HgCl(2)(C(10)H(9)N(3))], the Hg(II) atom is four-coordinated in a distorted tetra-hedral configuration by two N atoms from the chelating di-2-pyridylamine ligand and by two Cl atoms. In the crystal structure, inter-molecular N-H⋯Cl hydrogen bonds link the mol-ecules into centrosymmetric dimers. There is a π-π contact between the pyridine rings [centroid-...
