摘要:Abstract(#br)The paper presents an application of large eddy simulations (LES) to predict the course of barium sulfate precipitation carried out in jet reactors and basic guidelines for a reactor design. The reactors in question were of different geometries and made in differen...

摘要:Nanomaterials like cerium oxide and barium sulfate are frequently processed in industrial and consumer products and exposure of humans and other organisms is likely. Generally less information is given on health effects and toxicity, especially regarding long-term exposure to low...

摘要:Abstract(#br)Barium sulfate with lamellar and tubular microstructure was developed through a surfactant templating route under different synthesis conditions. Lamellar barium sulfate was synthesized through direct combination of Ba 2+ and SO 4 2 − in an ...

摘要:Abstract(#br)We have shown that barium [from BaSO4 nanoparticles (NPs)] was cleared from the lungs faster than other poorly soluble NPs and translocated mostly to bone. We now studied barium biokinetics in rats during Study 1: two-year inhalation exposure to 50 mg/m...

摘要:Abstract(#br)In this article, a new double spinning disks reactor (DSDR) has been proposed and tested successfully for the synthesis of barium sulfate nanoparticles by means of the reactive precipitation. The proposed DSDR consists of two coaxial rotating disks placed horizontall...

摘要:Abstract(#br)Barium sulfate particles were synthesized in the presence of EDTA at room temperature. X-ray diffractometry (XRD), Fourier transform infrared resonance (FTIR) and scanning electron microscopy (SEM) were used to characterize the structure and morphology of BaSO 4 p...

摘要:Abstract(#br)The surface electrical properties of precipitated barium sulfate in aqueous solution have been probed in the presence and absence of synthetic poly α, β aspartic acid. The effect of cation type, ion concentration, and pH on the electrokinetic properties of barite ...

摘要:... In this paper, various techniques are used to elucidate the mechanism of interaction between EDTA and barium sulfate surfaces. It is shown that complexation with metal ions is not sufficient to explain the inhibition of barite crystallization but that other processes suc...

摘要:Abstract(#br)This paper investigates the influence of barium sulfate scaling and scaling inhibitors on the electrochemical behaviour of stainless steel. The results of a synchrotron radiation grazing incidence X-ray diffraction (SR-GIXRD) and electrochemical impedance spectroscop...

摘要:Abstract(#br)The precipitation of barium sulfate from aqueous solutions of barium chloride and sodium sulfate was investigated experimentally in a continuous Y-Mixer to avoid any mixing influence. Initial supersaturation and the initial ratio R = c B a free 2+ / c S O 4 , free 2...
