Research ArticleOpen accessEvery word in the titleDissolution Sintering Technique to Create Porous Copper with Sodium Chloride Using Polyvinyl Alcohol Solution through Powder MetallurgyCynthia Waters, Stephen Ajinola, Mustafa SalihThe main purpose of this paper was to investigate the relative densities, porosities, compression strength and energy absorbed by porous copper (Cu) formed via the dissolution sintering technique using Polyvinyl Alcohol (PVA) solution as a binder with Sodium Chloride (NaCl) as space holder. Porous Cu was fabricated through powder metallurgy route using dissolution sintering technique by mixing Cu with NaCl … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 1 · 13 Mar 2016 · 8,985 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsPlastic Membrane Electrodes of Coated Wire Type for Micro Determination of Quininium Cation in Pharmaceutical TabletsLaila Abdullah Al Shatti, Hayat Mohammed Marafie, Adel Fahmi ShoukryProblem statement: Silver and copper all-solid state wire sensor electrodes of quininium cation with different ion exchangers have been prepared and used in pharmaceutical analysis. A comparative study with a reference method is applied in order to investigate the validity of the proposed method for potentiometric analysis of pharmaceutical compounds containing quinine. Approach: A Nernstian equation was proved for all … …American Journal of Applied Sciences, Vol. 8, Issue 2 · 28 Feb 2011 · 7,690 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPorosity Analysis in Porous Brass Using Dual ApproachesRyan Yeargin, Rob Ramey, Cindy WatersThe goal of this research is to produce porous samples for various applications such as heat exchangers, filters and radiation shields. The level of porosity is an important objective yet the level of confidence in two main methods (hand calculations and microscopic analysis) is not high. This work will compare porosity values obtained from traditional hand calculations against analysis from … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 1 · 25 Feb 2016 · 8,525 accessesView PDF Cite
