-
(1988)An analysis of satellite IR surveys of the earth surface in the wavelength interval from 10.5 to 11.3 μm indicated that a temporally and laterally stable increase in the intensity of the outgoing IR radiation flux, compared ...
-
(2000)The Beer–Lambert law is traditionally used to determine water and carbon concentrations in glasses from their infrared (IR) spectra. In practice, this method requires estimation of the thickness and density of the glass ...
-
(1997)The sediment sequence at Ocean Drilling Program (ODP) Site 910 (556 m water depth) on the Yermak Plateau in the Arctic Ocean features a remarkable ``overconsolidated section'' from ˜ 19 to 70-95 m below sea floor (m bsf), ...
-
(2002)Recognising the utility of grass buffer strips in sediment retention, a fundamental hydraulic interpretation of flow through such strips is sought. In order to ensure reproducibility of results, a model porous resistive ...
-
(2001)Overpressured zones in the Precaspian Basin occur at depths below 4000 m. The most extensive zone is in the subsalt reservoirs throughout the basin. In spite of the extended literature database on overpressure phenomena, ...
-
(2004)Of the eighty-three naturally occurring elements that are not radioactive or have half lives long enough to be considered stable (>109 yrs), nearly three-quarters have two or more isotopes. Variations ...
-
(2002)Environmental legislation has had significant impact on coal utilization, especially coal combustion for power generation, in limiting emissions of potentially hazardous materials to the environment. For the most part, ...
-
(1995)Batch interaction experiments were performed under aerobic conditions to characterize the adsorption behavior and valence speciation of CoEDTA complexes (equimolar at 10-5 mol/L) in a series of Pliocene subsurface sediments ...
-
(1997)Manganese oxidation rates were determined at low (#20 nM) concentrations in seawater by measuring dissolved manganese (Mn(II)) using flow injection analysis with chemiluminescence detection. Mn(II) was measured in samples ...
-
(2005)Sorption and transformation of 1-naphthol by a K-smectite (K-SWy-2) were studied using batch sorption isotherms, Fourier-transform infrared spectroscopy (FTIR), and X-ray diffraction (XRD). The sorbents included three ...
-
(2001)Amorphous forms of natural and synthetic Fe oxyhydroxides and synthetic Mn oxyhydroxides were used to study the oxidation of antimonite, Sb(III), at different pH values. Sb species were measured by differential pulse ...
-
(1999)X-ray Photoelectron Spectroscopy (XPS) was used to investigate oxidation of aqueous Cr(III) at the surface of 7 #9-birnessite [MnO1.75(OH)0.25]. Special emphasis was placed on detection of intermediate oxidation states of ...
-
(1995)Arsenic and sulphur, and possibly iron, exist in multiple oxidation states in the near-surface of unoxidized arsenopyrite. X-ray photoelectron spectroscopy (XPS) of an unoxidized surface reveals that sulphur is present as ...
-
(1996)Cobalt and manganese uptake onto suspended particles was studied in waters collected from Waquoit Bay, Massachusetts and the upper water column of the Sargasso Sea using radiotracers, coupled with protocols used previously ...
-
(2001)Oxidation of pyrite (FeS2) under anaerobic conditions in marine sediments is experimentally shown for the first time. In slurry experiments with 55FeS2 and a MnO2 rich marine sediment an oxidation of 55FeS2 was detected ...
-
(1988)The characteristic hypogene mineralization in silver deposits is represented by silver sulfosalts (pyrargyrite, freibergite, polybasite, stephanite, or stromeyerite) in addition to galena, sphalerite, chalcopyrite and ...
-
(2001)High-resolution Fe K-edge XANES spectra of a series of crystalline Fe2+- and Fe3+-bearing model compounds were measured in an effort to correlate characteristics of the pre-edge feature with oxidation state and local ...
-
(2001)The acid and base dissociation constants of FeO and Fe2O3 components in silicate melts are defined in terms of observed relationships between atomistic properties of dissolved oxides (nephelauxetic parameters, electronegativity, ...
-
(1986)Precise new analyses of ferrous and total iron for 78 hand-picked mid-ocean ridge basalt (MORB) glasses constrain the redox states of MORB magmas, and the systematics of those redox states with respect to geography and ...
-
(2000)The crystal chemistry of Fe in four nontronites (Garfield, Panamint Valley, SWa-1, and NG-1) was investigated by chemical analysis, X-ray goniometry, X-ray absorption pre-edge spectroscopy, powder and polarized extended ...
