Research ArticleOpen accessEvery word in the titleSynthesis and Characterization of Organoclay from Sodium Montmorillonite and Fatty Hydroxamic AcidsWisam H. Hoidy, Mansor B. Ahmad, Emad A. Jaffar Al Mulla, Nor Azowa Bt IbrahimProblem statement: Sodium Montmorillonite (Na-MMT) has been modified via cation exchange reaction using Fatty Hydroxamic Acids (FHAs) synthesized from palm oil as a surfactant to produce organoclay which is used to prepare polymer nanocomposites. Approach: Basal spacing, functional groups identification and thermal stability of this Organo-Montmorillonite (OMMT) were characterized using X-ray Diffraction (XRD), Fourier Transform Infrared (FTIR) spectroscopy and Thermogravimetric … …American Journal of Applied Sciences, Vol. 6, Issue 8 · 31 Aug 2009 · 9,305 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleApplication of Bio-Modified Montmorillonite Clay to Enhance Asphalt Oxidation ResistanceShahrzad Hosseinnezhad, Elham H. Fini, Taher M. Abu-LebdehThis study evaluates the effectiveness of using a Bio-modified Nanoclay additive (BNC) to reduce the oxidative aging of asphalt pavements. The study results through X-Ray Diffraction analysis showed that the modification of montmorillonite clay with bio-modifier increased the basal d-spacing of clay. The resulting nanoclay with increased interlayer spacing was chosen for application in asphalt binder. Rheological characterization of clay-modified … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 31 Mar 2018 · 9,054 accessesView PDFCite
Research ArticleOpen accessIn the keywordsSynthesis and Characterization of Silver/Clay Nanocomposites by Chemical Reduction MethodMansor Bin Ahmad, Kamyar Shameli, Majid Darroudi et al.Problem statement: Silver Nanoparticles (Ag-NPs) have been synthesized by using chemical reduction method into the interlayer space of a Montmorillonite (MMT) as a solid support which is used to antibacterial application and polymer nanocomposites for fabrication of medical devices. Approach: AgNO3 and NaBH4 were used as a silver precursor and reducing agent, respectively. The properties of Ag/MMT nanocomposites were studied … …American Journal of Applied Sciences, Vol. 6, Issue 11 · 30 Nov 2009 · 8,169 accessesView PDFCite
Research ArticleOpen accessIn the abstractSynthesis and Characterizations of MmtO-Copolymer (St-THF) NanocompositeHattab Youcef, Hakiki WahibaNanocomposites are synthesized by one or two polymers and optimized organophilic clay proportions. The aim of Synthesis of the Organophilic clay (montmorillonite) with a two monomers to get a copolytetrahydrofuran- styrene nanocomposite by insitu polymerization. Organophilic montmorillonite (MmtO) was synthesized by ion exchange between Na+ ions in the clay and HDTMAB alkylammonium cations in an aqueous medium. The MmtO were … …American Journal of Applied Sciences, Vol. 16, Issue 10 · 19 Dec 2019 · 7,116 accessesView PDFCite
Research ArticleOpen accessIn the abstractSynthesis and Characterization of Silver/Clay/Chitosan Bionanocomposites by UV-Irradiation MethodMansor Bin Ahmad, Kamyar Shameli, Majid Darroudi et al.Problem statement: Silver/Montmorillonite/Chitosan Bionanocomposites (Ag/MMT/Cts BNCs) have been synthesized by UV-irradiation reduction method in the absence of any reducing agent or heat treatment which is used to antibacterial application and medical devices. Approach: MMT, Chitosan and AgNO3 were used as a solid support, stabilizer and silver precursor, respectively. The properties of Ag/MMT/Cts BNCs were studied as a function of UV-irradiation … …American Journal of Applied Sciences, Vol. 6, Issue 12 · 31 Dec 2009 · 8,815 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Grain Size on Selected Physico-Chemical Properties of ClayOsumanu Haruna Ahmed, Nik Muhamad Ab. Majid, Mohamadu Boyie JallohProblem statement: Mixture of the right proportion of expanding and non-expanding clays to improve plasticity (moldability) of clays used in the pot industry of Malaysia is yet to be well investigated. In addition, little is known about the choice of the right clay size to eliminate or reduce the content of undesirable compounds such as Fe2O3, Al2O3 to improve the … …American Journal of Environmental Sciences, Vol. 5, Issue 5 · 31 Oct 2009 · 7,152 accessesView PDFCite
Review ArticleOpen accessIn the abstractA Brief Review of the Latest Advances of Attapulgite as a Reinforcing Agent in Polymer Matrix NanocompositesThais Ferreira da Silva, Gabriel Portilho Monteiro de Souza, Guilherme Ferreira de Melo Morgado et al.The development of polymeric nanocomposites using clay minerals as a Nano filler is of great interest to researchers and industry. Many clay minerals are used to modify the properties of the polymers; this strategy improves the thermal and mechanical performance and changes the surface finishing and the processing characteristics. The Attapulgite (ATP), which is a clay mineral of the hydrated … …American Journal of Engineering and Applied Sciences, Vol. 14, Issue 2 · 3 Jun 2021 · 7,419 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Removal of 4-Chlorophenol and Dichloroacetic Acid in Water Using Ti-, Zr- and Ti/Zr-Pillared Bentonites as PhotocatalystMohamed Houari, Mohamed Saidi, Djamel Tabet et al.Heterogeneous photocatalysis could be alternative remediation technology for water since it does not need the addition of any chemicals and it is suitable for treating low concentrations of pollutant. Although the TiO2 Degussa P 25 is most used photocatalyst its photonic efficiency still low and its recovery from water is considered as an awkward process. In this study the effect … …American Journal of Applied Sciences, Vol. 2, Issue 7 · 31 Jul 2005 · 7,518 accessesView PDFCite
