The chemical composition and aluminum speciation of sludge incineration residue (SIR) were determined. Cementation of aluminum from sulfuric acid solution using SIR was studied. The results showed that acid-soluble inorganic aluminum was the predominant component in the sludge, and the total leached aluminum increased from 62.2% to 92.9% after incineration. Sulfuric acid dosage and reaction tim...

This article introduces tri-cationic hemicyanine dye employed as a visible-light photoinitiator of acrylic monomers polymerization. This dye, in combination with borate anions, was found to be a very effective photoinitiating system. The kinetics of trimethylolpropane triacrylate polymerization was studied by a microcalorimetric method. The photoredox pair concentration, the co-initiator struct...

The Hopper XE6 system, NERSC’s first peta-flop system with over 153,000 cores has increased the computing hours available to the Department of Energy’s Office of Science users by more than a factor of 4. As NERSC users transition from the Franklin XT4 system with 4 cores per node to the Hopper XE6 system with 24 cores per node, they have had to adapt to a lower amount of memory per core and onn...

MapReduce has emerged as a successful framework for addressing the heavy demand for large-scale analytical data processing, in this peta-byte age. However, while on one hand the sheer size of data makes problems more challenging, the flexibility offered by the MapReduce frameworks on the other hand, makes the learning curve far steeper than expected. The general idea behind a MapReduce framewor...

Aluminum is the most abundant metal on earth. It is not known to have any biological metabolism; conversely it has a toxic effect that has been related to several damages including some neurodegenerative diseases. We sampledcerebrospinal fluid (CSF) in 141 patients with different chronic diseases, assessing the levels of aluminum contained. Our aim was to assess differences in aluminum levels b...

During the last 15 years, accumulating evidence has implicated aluminum in disorders associated with chronic renal failure.’6 The well-recognized manifestations of systemic aluminum toxicity include fracturing osteomalacia, dialysis encephalopathy, and microcytic hypochromic anemia. More recently, aluminum loading has been demonstrated in premature infants receiving intravenous fluid therapy.7 ...

Hermetic aluminum-coated fused silica fibers can withstand high stress levels without failure for prolonged periods of time in water-containing environments. Aluminum-coated fibers from several sources exhibit differences in strength. The aluminum and silica surfaces have been examined using SEM and AFM in order to understand this variation. Differences in the interfacial interaction between al...
