A mathematical model of a lead‐acid cell is presented which includes the modeling porous electrodes and various physical phenomena in detail. The used to study dynamic behavior acid concentration, porosity electrodes, state charge during discharge, rest, charge. dependence performance on electrode thicknesses operating temperature also investigated.
A first principle mathematical model of the formation calcareous deposits on a cathodically protected steel rotating disk electrode in seawater is presented. The includes equations which transport phenomena, electrochemical reactions, precipitation and homogeneous reaction involved an surface. Predicted concentration profiles show that high OH− ions surface leads to deposits. contain mostly , but initial are predicted more than . reduce active area available for results decrease cathodic...
Background Human plague caused by Yersinia pestis remains a public health threat in endemic countries, because the disease is associated with increased risk of mortality and severe economic social consequences. During past 10 years, outbreaks have occasionally occurred Vietnam's Central Highlands region. The present study sought to describe analyse occurrence its association ecological factors. Methods included all 510 communes region (with total population ∼4 million) where 95% incidence...
This study aims to enhance the mechanical properties, thermal stability, weathering resistance and antibacterial property of a styrene acrylic polyurethane coating by adding rutile titania dioxide (R-TiO2) nanoparticles in formulation. The polyurethane/R-TiO2 nanocomposite had been prepared using ultrasonication. effects on stability as-prepared coatings were investigated adhesion strength ball impact tests, Fourier transform infrared UV–vis analyses, thermogravimetric analysis (TGA),...
For the vulcanized natural rubber (NR), incorporation of silver nanoparticles (AgNPs) into NR matrix did not exhibit bactericidal property against Escherichia coli ( E. ). However, AgNPs polyethylene (PE) showed good antibacterial activities to both Gram-negative and Gram-positive bacteria. In present work, NR/PE (85/15) blends have been prepared by melt blending with presence compatibilizer in an internal mixer. To possess property, (5–10 nm) or Fe 3 O 4 –Ag hybrid (FAgNPs, 8 nm/16 were...
This study aims to evaluate the synergical effects of SiO2 nanoparticles (nano-SiO2) and organic photostabilizers (Tinuvin 384 (T384) Tinuvin 292 (T292)) on weathering resistance acrylic polyurethane coating. Data obtained from infrared (IR), field emission scanning electron microscopy (FESEM), weight loss coatings (before after aging test), suggest that play a dual role, as both reinforcer UV absorber, thus improving effectively mechanical properties coatings. The nanocomposite coating...
This work aims to explore how ZnO nanoparticles enhance the mechanical, photoaging, and self cleaning properties of water borne acrylic coating. Micro/nano particles (at 2 wt.% total solid resin) were dispersed into polymer matrices using ultrasonication understand effect size coating properties. The on composite coatings (25 µm thick) have been evaluated through various tests, such as abrasion measurement, ultraviolet/condensation (UV/CON) weathering aging, methylene blue cleaning....
Purpose This study aims to explore how the inhibitor-loaded nanocontainers can be used in epoxy coating for protection of steel against corrosion. A self-healing anticorrosive easily fabricated by embedding into matrices. For this purpose, first, cerium (a catholic corrosion inhibitor) is encapsulated silica nanoparticles (SiO 2 @Ce). Thereafter, an nanocomposite has been prepared on substrate using these SiO @Ce as nanofillers. Design/methodology/approach To examine effect mechanical...
