A versatile method for preparing spherical, micro- and macroporous (micro: 2-10 and macro: 150-550 microm pores), carbonated apatitic calcium phosphate (Ap-CaP) granules (2-4 mm in size) was developed by using NaCl crystals as the porogen. The entire granule production was performed between 21 and 37 degrees C. A CaP cement powder, comprising alpha-Ca3(PO4)2 (61 wt.%), CaHPO4 (26%), CaCO3 (10%)...

Local purinergic signals modulate renal tubular transport. Acute activation of renal epithelial P2 receptors causes inhibition of epithelial transport and thus, should favor increased water and salt excretion by the kidney. So far only a few studies have addressed the effects of extracellular nucleotides on ion transport in the thick ascending limb (TAL). In the medullary thick ascending limb (...

We investigated film thickness effects of sulfuric acid anodized aluminum when galvanically coupled with carbon fiber reinforced plastic（CFRP）. The CFRP was electrically to alloys 1050, 5052, 6061, and 7075 in 3.5 wt.% NaCl solution at 35 ℃. Galvanic current passing from the 1050 6061 decreased as anodic oxide thickened. For galvanic between 5052 CFRP, elapsed time until corrosion density value...

A microporous polypropylene (PP) hollow fiber membrane contactor was used as a reactor to biodegrade phenol in high-salinity solutions by Pseudomonas putida CCRC14365 at 30C. Suspended cells grew only at a NaCl concentration below 2.5 wt%. On the other hand, cells within hollow fibers completely degraded 0.5 g/L of phenol in solution containing NaCl up to 8.6 wt%, likely due to the fact that th...

Electrochemical corrosion and passivation characteristics of the oxide dispersion strengthened (ODS) Fe3Al–Ti ODS Fe3Al–Ti–Zr alloys immersed for different exposure times 1, 72, 120, 166 240 h in 3.5 wt % NaCl solution were studied using open-circuit potential, cyclic polarization electrochemical impedance spectroscopy techniques. Both exhibit pitting under chloride ions exposure. In both alloy...

Abstract The corrosion behavior of E690 steel in 3.5 wt.% NaCl solution at temperatures from 20 °C to 60 was investigated using electrochemical test. morphology characterized SEM and AFM, the layer EDS, Raman spectroscopy XPS. results showed that rate improves with increase temperature. layers are mainly composed α -Fe 2 O 3 , -FeOOH γ -FeOOH. With elevated temperature, content increases, while...

In this study, corrosion behavior of copper that was deformed by Simple Shear Extrusion (SSE) method was investigated in 3%wt NaCl solution. Modified Williamson-Hall method, applied on the X-ray diffraction patterns of the samples, showed that increase in the number of SSE passes led to increasing in the dislocation density in the copper samples. Moreover, such deformed samples exh...

the density and viscosity of carbonated aqueous 35wt% methyldiethanolamine solution were experimentally measured accompanied with the solubility of co2 at temperatures from (303.15 to 363.15) k and pressures up to 0.8 mpa using the new setup developed in our laboratory.it was observed that both density and viscosity of mixtures decrease by increasing temperature and increase by increasing acid ...
