  • Emulsion-Breaking Techniques for Accurate Oil in Water Measurements

    A White Paper discusses emulsion-breaking techniques for ensuring accurate oil in water measurements. Certain water samples, such as those containing detergent, may form an emulsion when oil in water extraction into a solvent is done. In order to ensure an accurate measurement, the emulsion must be broken. Six techniques are described that can be used for reducing an emulsion ...

  • Green synthesis of ZnSe quantum dots using in-situ synthesised sodium selenide

    Single-step green synthesis of zinc blende ZnSe quantum dots (QDs) is performed using sodium selenide and zinc stearate. The present method is non-toxic and is considered reasonably green route where stearate ions released during the reaction act as surfactant. The size quantisation effect is revealed by blue shifted absorption bands with a band-gap energy of ~2.9 eV with respect to bulk ZnSe ...

  • Self-welding susceptibility of 316LN and alloy D9 stainless steels in high-temperature flowing sodium

    The self-welding susceptibility of 316LN Stainless Steel (SS) and alloy D9 (15Cr-15Ni-2Mo titanium-modified) SS in 20% cold-worked conditions was evaluated in flowing sodium at 823 K under a maximum contact stress of 12 MPa and for durations of 3, 6 and 9 months. The specimens used were hollow, cylindrical and stacked one above the other under compression using disc springs. The breakaway shear ...

  • Direct observations of membrane scale in membrane bioreactor for wastewater treatment application

    The formation of inorganic fouling on MF membrane was investigated in membrane bioreactor (MBR) treating industrial wastewater. Membrane autopsy works using microscopic techniques and surface analysis were carried out at the completion of pilot-scale operation to analyze foulant materials extensively. Scaling occurred on the membrane surface significantly in the MBR treating calcium-rich ...

  • Evaluating the surface protection and decontamination efficiency of DeconGel 1101 toward Cs-137 spilled on biological, salt-covered, rusty, wet and solid painted surfaces

    This thesis presents an approach to develop innovative methods for decontamination and surface protection applicable to naval nuclear ships and potentially, personnel, replacing antiquated techniques. To accomplish this goal, two products manufactured by CBI Polymers, LLC., DeconGel™ 1101 (1101) and a shampoo, DeconGel™ 'prototype' (prototype), were tested. The prototype was specially ...

  • Development of resistivity probes for continuous monitoring of pollutant in porous media

    In this study, an attempt has been made to develop resistivity probes and an experimental setup capable of simulating the field conditions concerned with migration of pollutant through the porous media. The porous media chosen for the present study is commercially available uniformly graded sand; while Sodium Chloride solution was considered as the pollutant. For the continuous monitoring of ...

  • Monitoring surface water chemistry near magnesium chloride dust suppressant treated roads in Colorado

    Received for publication January 31, 2009. Magnesium chloride (MgCl2)-based dust suppression products are commonly used throughout western United States on nonpaved roads for dust suppression and road stabilization by federal, state, and county transportation agencies. The environmental implications of annually applying these products throughout spring and summer months on adjacent stream ...

  • Genetic variation and the effectiveness of early-generation selection for soft winter wheat quality and gluten strength

    Selection for milling and baking quality in wheat (Triticum aestivum L.) head-rows could increase the efficiency of most soft winter wheat (SWW) breeding programs. We evaluated whole grain-wheat meal (WM) assays for their ability to select lines with acceptable SWW quality and high gluten strength in early-generations and estimated heritability of SWW quality and gluten strength. One hundred ...

  • Saccharomyces cerevisiae grx6 and grx7 are monothiol glutaredoxins associated with the early secretory pathway

    Saccharomyces cerevisiae Grx6 and Grx7 are two monothiol glutaredoxins whose active-site sequences (CSYS and CPYS, respectively) are reminiscent of the CPYC active-site sequence of classical dithiol glutaredoxins. Both proteins contain an N-terminal transmembrane domain which is responsible for their association to membranes of the early ...

  • Calibration stability of the sievers 900 series TOC analyzers

    Objective One of the advantages of the membrane conductivity measurement system employed in the Sievers 900 Series TOC Analyzers, compared to other TOC analyzers, is the excellent stability of the calibration.

The Pulsar equipment replaced ultrasonic equipment previously supplied by ...

  • Comparing the Realities of Elemental Chlorine vs. Sodium Hypochlorite

    Recently, we have seen a growing trend towards the use of a less reliable and more costly disinfection chemical, Sodium Hypochlorite. Much of this can be attributed to the fact that large companies making chemical metering pumps for other uses or other alternative disinfection devices as well as chemical suppliers who profit more by selling costly Sodium Hypochlorite have proliferated misleading ...
