Surface plasmon resonances on bilayer aluminum nanowire gratings are studied in both theory and experiment. It is found that there are two kinds of surface plasmon on the bilayer metallic gating: longitudinal aluminum/dielectric/aluminum slit and lateral aluminum/dielectric interface waveguide mode. The surface plasmon waveguide mode resonance in the slits makes the grating act as a transverse ...
introduction: the objective of this study was, wastewater quality investigation and removal efficiency of contaminants from the wastewater tile factory by using coagulants includes ferric chloride, ferric sulfate and ferrous, aluminum sulfate and poly aluminum chloride in order to reuse it in the processing line. methods: this is an applied study. with regard to shiftwork schedules of the fact...
In rats, gastrointestinal aluminum absorption and tissue distribution were altered by parathyroid hormone; the resultant tissue concentrations were similar to those observed in dialysis patients with a fatal encephalopathy. In dialysis patients, serum aluminum and endogenous parathyroid hormone concentrations are significantly correlated. These data suggest that aluminum toxicity in dialysis pa...
The Electrochemical Society Interface • Spring 1999 FIG. 1. Cross section of a 6-level copper wiring structure fabricated by IBM showing wiring hierarchy. n-chip interconnections comprise a multilevel structure of fine wiring located on the top of the transistor circuitry of logic or memory chips, whose role is to connect circuits together as shown in Fig. 1. To avoid significant degradation of...
Although aluminum itself was reported to prevent dental caries, previous in vitro studies reported that the aluminum level in the whole saliva of children was independent of caries prevalence. Purposes of this study were to compare the elution levels of aluminum and calcium from deciduous enamel into acidic artificial saliva, and determine whether the degree of aluminum elution reflects individ...
Industrialized societies produce many convenience foods with aluminum additives that enhance various food properties and use alum (aluminum sulfate or aluminum potassium sulfate) in water treatment to enable delivery of large volumes of drinking water to millions of urban consumers. The present causality analysis evaluates the extent to which the routine, life-long intake, and metabolism of alu...
BACKGROUND During the last years, human newborns have been overexposed to biologically reactive aluminum, with possible relevant consequences on their future health and on their susceptibility to a variety of diseases. Children, newborns and particularly preterm neonates are at an increased risk of aluminum toxicity because of their relative immaturity. DATA SOURCES Based on recent original p...
Most humans living in industrialized societies are routinely exposed to bioavailable aluminum salts in the form of additives-in commercially-prepared foods, alum-clarified drinking water, certain pharmaceuticals, sunscreens, and other topical applications. Minute amounts of this aluminum are absorbed into the circulation. Trace aluminum levels cross the blood-brain barrier and progressively acc...
as a high temperature structural ceramic, cermets exhibit less brittleness than ceramic-ceramic composites or monolithic ceramics owing to the presence of a ductile metal second phase in their microstructure. these cermets can, therefore, be used in applications where the abrasive, creep and thermo-mechanical resistance are required. in the present study, aluminum-alumina cermets with different...
Abstract Aluminum foam sandwich (AFS) is an innovative material for lightweight structures, consisting of aluminum core surrounded by two face sheets aluminum. The advantages AFS are a low density combined with high bending stiffness, good energy absorption properties, and recyclability, meaning it can be used many different applications. However, the number realized series applications caused ...
