Molecular relaxation effects in hydrogen chloride photoacoustic detection

A photoacoustic (PA) sensor has been developed to monitor hydrogen chloride at sub-ppm level in the 1740-nm region. The system was designed to control the process in the novel low-water-peak optical fiber manufacturing process. Relaxation effects in hydrog ...

Arsenic sequestration by sorption processes in high-iron sediments

Janet Gordon Hering

High-iron sediments in North Haiwee Reservoir (Olancha, CA), resulting from water treatment for removal of elevated dissolved arsenic in the Los Angeles Aqueduct system, were studied to examine arsenic partitioning between solid phases and porewaters under ...

Effect of groundwater composition on arsenic detection by bacterial biosensors

A luminescent bacterial biosensor was used to quantify bioavailable arsenic in artificial groundwater. Its light production above the background emission was proportional to the arsenite concentration in the toxicologically relevant range of 0 to 0.5 mu M. ...

GaN-based single mirror light emitting diodes

Jean-François Carlin, Marc Ilegems, Julien Dorsaz

We present a study on the dependence of the external Quantum Efficiency (QE) of Light Emitting Diodes (LEDs) on the device properties and p-contact metallisation. The external QE could be doubled by changing the p-type contact from oxidised Ni/Au to non-an ...

Heterogeneous reactions of tropospheric trace-gases on solid model aerosol surface

Christian Santschi

The first part of this laboratory study deals with heterogeneous reactions of bromine- and chlorine-containing species relevant to the atmosphere with solid model alkali salt substrates. The second part of this work treats the heterogeneous interaction of ...

Disodium tetrasupersilyltetragallanediide Na2Ga4R4.2THF (R = SitBu3). Preparation of a novel gallium cluster compound via dichlorodisupersilyldigallane R*2Ga2Cl2

Red tetragallanediide Na2Ga4R4.2THF (R = SitBu3) was prepd. by redn. of the monogallane RGaCl2.THF in heptane or the tetrahedro-tetragallane R4Ga4 in benzene/THF with sodium at 100 Deg. Potassium worked analogously as a redn. agent. As an intermediate ...

Deposition and fate of arsenic in iron- and arsenic-enriched reservoir sediments

Janet Gordon Hering

Deposition of arsenic to the sediments of Haiwee Reservoir (Olancha, CA) has dramatically increased since March 1996 as a result of an interim strategy for arsenic management in the Los Angeles Aqueduct (LAA) water supply. Ferric chloride and cationic poly ...

Arsenic occurrence and speciation in municipal ground-water-based supply system

Janet Gordon Hering

The city of Hanford, California, relies on ground water for its municipal water supply. Arsenic concentrations in local wells frequently exceed the current drinking water standard (50 μg/L), although some dilution is achieved within the distribution system ...

Arsenic adsorption and oxidation at manganite surfaces. 1. Method for simultaneous of determination of adsorbed and dissolved arsenic species

Janet Gordon Hering

Arsenic occurs in the +III oxidation state as a metastable species in oxic waters. Under oxic conditions, As(III) is both more mobile in natural waters and less efficiently removed by water treatment processes than As(V). Other oxidants, however, can react ...
