Treatment of Bi(2)O(3) with the acids; S-(+)-10-camphorsulfonic, 2,4,6-mesitylenesulfonic and sulfamic, under sonication at room temperature in water for 2-4 h, results in the formation and subsequent crystallisation of polynuclear bismuth oxido-clusters; [Bi(18)O(12)(OH)(12)(O(3)S-Cam)(18)(H(2)O)(2)], [Bi(38)O(45)(O(3)S-Mes)(24)(H(2)O)(14)] and [Bi(6)O(4)(OH)(4)(O(3)SNH(2))(6)].

Aluminum enters municipal solid waste MSW landfills from untreated raw curbside trash MSW , industrial waste, and aluminum production wastes variously called dross, baghouse fines, salt cake, and other designations. Aluminum related reactions can arise and become problematic for landfill operations by generating undesirable heat, liquid leachate, and gases, such as hydrogen, hydrogen sulfide, c...

Recently Johansson and Rahman obtained the limiting multitime distribution for discrete polynuclear growth model (Johansson (2019)), which is equivalent to a TASEP with step initial condition. In this paper, we obtain finite time multipoint formula of continuous general conditions in space-time plane. We evaluate limit function when times go infinity at same speed both flat conditions. These di...

Aluminum is a strategic mineral resource, and China’s aluminum production and consumption is fairly large. However, its supply guarantee is uncertain because of a high dependency on external raw materials. This uncertainty may expand, so finding a way to reduce the uncertainty of aluminum resource supply is especially important. This paper applies the SFA method to analyze the aluminum flows in...

aluminum is present in very small amounts in living organisms but abundant in the environment. a growing literature links with the biochemistry of aluminum and also with a series of diseases in chronic renal failure patients on treatment with hemodialysis. the initial description of potential aluminum toxicity in renal failure patients relates to description of dialysis encephalopathy syndrome ...

background: an increase in surface roughness of ceramics may decrease strength and affect the clinical success of ceramic restorations. however, little is known about the effect of acidic agents on ceramic restorations. the aim of this study was to evaluate the surface roughness of dental ceramics after being immersed in acidic agents.     methods: eighty-three ceramic disk specimens (12.0 mm i...

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...

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...
