Research ArticleOpen accessIn the keywordsCoating and Encapsulation of Nanoparticles using Supercritical AntisolventG. H. Chong, R. Yunus, N. Abdullah et al.Problem statement: Literature on the production of nanoparticles using supercritical fluids is substantial, but comparatively much less for nanoencapsulation. Approach: In this study, a modified Supercritical Anti Solvent (SAS) apparatus was fabricated for use in the production of nanoparticles using carbon dioxide as the supercritical fluid (SCF). SAS technique involves precipitation of solids from liquid solution under supercritical antisolvent-induced condition. … …American Journal of Applied Sciences, Vol. 6, Issue 7 · 31 Jul 2009 · 8,417 accessesView PDF Cite

Research ArticleOpen accessIn the abstractVisible Derivative Spectroscopic Monitoring of the Old Woman Creek National Estuary During a Historically Dry Year and a Wet YearLorita Nivanthi Mihindukulasooriya, Brenna Shae Mabry, Madison Slocum, Joseph Daniel OrtizVisible derivative spectroscopy was used to interpret the sediment and phytoplankton assemblages within the old woman creek natural estuarine reserve during the summers of 2016 and 2017. A Varimax-rotated Principal Component Analysis (VPCA) of reflectance data collected from four sampling sites in 2016 identified three Varimax-rotated Principal Components (VPCs): Diatom + Illite (2016-VPC 1), Dinoflagellate Algae + Cyanobacteria + Cryptophytes … …American Journal of Environmental Sciences, Vol. 19, Issue 6 · 11 Jul 2024 · 4,669 accessesView PDF Cite

Research ArticleOpen accessIn the abstractBasalt as Pozzolana and Filler in Ordinary Portland CementH. El-Didamony, I.M. Helmy, Randa M. Osman, A.M. HabboudPozzolana is defined as a siliceous or siliceous and aluminous materials which in itself possess little or no cementing properties, but will in a finally divided form and in the presence of moisture react with Ca(OH)2 at ordinary temperature to form compound possessing cementious properties. Pozzolanic cement contains Portland cement as one of their main components in addition to natural … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 2 · 24 Jun 2015 · 7,904 accessesView PDF Cite
