Research ArticleOpen accessPhrase in the titleThermodynamic Modeling and Heat-Moisture Transfer Characteristic Analysis of in Situ Thermal Desorption System for Polluted SoilHuijuan Xu, Yanjun Bi, Lijun Gao, Dongxiao MaIn Situ Gas Thermal Desorption (ISGTD) is one of the effective approaches for organic contaminated soil. To investigate the heat-moisture transfer characteristics of soil during the heating process, a radially layered coupled heat-moisture model of the ISGTD system is established. The temperature and moisture distribution along the radial direction of the heat source, as well as the synergistic action of … …American Journal of Biochemistry and Biotechnology, Vol. 20, Issue 3 · 28 Aug 2024 · 4,035 accessesView PDF Cite

Research ArticleOpen accessIn the abstractOsmotic Tension, Plasticization and Viscoelastic response of amorphous Poly-Ether-Ether-Ketone (PEEK) equilibrated in humid environmentsAversa Raffaella, Apicella AntonioDynamic-Mechanical Analysis (DMA), Differential scanning Calorimetry (DSC) and water moisture sorption-desorption kinetics and equilibria have been parallely investigated to monitoring the environmental and thermal sensitivity of amorphous thermoplastic Poly-Ether-Ether-Ketone (PEEK). Morphological modification occurring in PEEK during the calorimetric and thermo-mechanical characterizations and the hygrothermal stability are presented. An interpretation based on the free energy of mixing of a polymer chains … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 3 · 14 Jul 2016 · 8,457 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSynthesis of Mesoporous Titania with Surfactant and its CharacterizationT. Benkacem, N. AgoudjilA mesoporous titania was obtained by gelation from Ti-alkoxide in acidic solutions with addition of surfactant cetyltrimetylammonium bromide (CH3(CH2)15N(CH3)3Br) using a sol-gel process. The effects of surfactant concentration on synthesis of mesoporous titania were studied. The structural characterisation was studied by differential thermal analysis, infrared spectroscopy, X-ray diffraction. Studies by X-ray diffraction showed that crystallisation of TiO2 powder occurs at … …American Journal of Applied Sciences, Vol. 5, Issue 11 · 30 Nov 2008 · 7,414 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAssessment of Canadian Regulations and Remediation Methods for Diesel Oil Contaminated SoilsD. G. Rushton, A E. Ghaly, K. MartinellDiesel fuel released into the environment can contaminate ground water, degrade potable water supplies and cause the collapse of fisheries. They are toxic to both animals and humans and can affect the liver, lungs, kidneys, and nervous system leading to cancer as well as immunological and reproductive effects. The objectives of this study were to review current Canadian regulations pertaining … …American Journal of Applied Sciences, Vol. 4, Issue 7 · 31 Jul 2007 · 8,758 accessesView PDF Cite
