• Effect of treated zeolite, iron waste, and liming on phytoavailability of Zn, Cu, and Ni in long-term biosolids-amended soils

  Soil Research · 2008-10-07 · 10 citations

  articleSenior author

  Two metal-contaminated biosolids-amended soils (moderately and highly contaminated) from the Bromley Sewage Treatment Farm, Christchurch, New Zealand, were used to evaluate the effect of remedial treatments on Ni, Zn, and Cu phytoavailability to sunflower (Helianthus annus L.). Two different chemical treatments (iron waste and treated zeolite), at 2 rates of application (5% and 10% w/w), in combination with 3 rates of a liming material (Ca(OH)2 at 0%, 0.33%, and 0.66% w/w) were evaluated for their metal remediation potential using pot experiments. Under the moderately acidic pH conditions of the original soils (pH 5.4–5.7), neither of the materials had substantial effects on plant metal concentrations, and the application of treated zeolite resulted in a large decrease in plant yield (&amp;gt;60% reduction). However, in the presence of Ca(OH)2, both materials showed some potential for reducing Ni and Zn concentrations in sunflowers compared with Ca(OH)2 alone. The best combinations of zeolite or iron waste with Ca(OH)2 resulted in reductions in shoot Ni concentrations to below the detection limit. For Zn, the best combinations of materials resulted in reductions in sunflower shoot Zn concentrations of 91% for the moderately contaminated soil and 75% for the highly contaminated soil. Combinations of iron waste and Ca(OH)2 in particular resulted in substantial decreases in soluble soil Zn concentrations (&amp;gt;90% reduction) and increases in plant yield (63% increase for highly contaminated soil), attributed to the remediation of Zn toxicity. There was little effect of any treatment on Cu concentration in the sunflower plants.

• Optics Performance at 1(omega), 2 (omega), and 3 (omega): Final Report on LDRD Project 03-ERD-071

  2006-02-08 · 2 citations

  reportOpen access

  The interaction of intense laser light with dielectric materials is a fundamental applied science problem that is becoming increasingly important with the rapid development of ever more powerful lasers. To better understand the behavior of optical components in large fusion-class laser systems, we are systematically studying the interaction of high-fluence, high-power laser light with high-quality optical components, with particular interest on polishing/finishing and stress-induced defects and surface contamination. We focus on obtaining comparable measurements at three different wavelengths, 1{omega} (1053 nm), 2{omega} (527 nm), and 3{omega} (351 nm).

• CMP slurry particle size spectrometer

  2002-11-19

  article1st authorCorresponding

  The particle size distribution in Chemical Mechanical Planarization (CMP) slurries is critical to the proper performance of the CMP Planarization process. Instrumentation in the past has been developed to measure the average particle size. However, just knowing the average particle size of the slurry will not prevent damaging scratches from occurring on high value planarized wafers. Fundamental physical properties and behaviours of slurries are strongly affected by both particle size and particle size distribution. This paper describes the application of a new instrument designed specifically for the measurement of particle size distribution in CMP slurries, with polishing particles that can range in size from 30 nanometers to 1100 nanometers. This new instrument, called the SPS-100, can resolve sub-populations with size differences as little as 10% in diameter. Slurries that have suffered change in critical polish particle size due to motion or temperature caused agglomeration in transit can be quickly identified. Slurries that tend to settle during shipment can be quickly certified for use through the use of this new instrument, after the slurry is remixed. This paper presents data from the slurry particle size spectrometer for various slurries used in CMP.
