Research ArticleOpen accessIn the keywordsImprovement of the Thermal, Photo and Mechanical Properties of Poly (Vinyl Chloride) in Presence of Poly (Glycidyl Methacrylate)Abir S. Abdel-NabyProblem statement: Poly (vinyl chloride) suffers from poor heat stability. The thermal degradation of the polymer leads to the evolution of hydrogen chloride gas, extensive discoloration of the polymer and lowering of physical and mechanical properties. Approach: Binary blends of Poly (Vinyl Chloride) (PVC) and Poly (Glycidyl Methacrylate) (PGMA) have been prepared by solution blending aimed at the improvement of … …American Journal of Applied Sciences, Vol. 8, Issue 7 · 24 Jun 2011 · 7,374 accessesView PDFCite

Zain, Rashid Atta Khan, Abdulbari Abdulrahman AhmedProblem statement: Heavy metal accumulation in waste water could affect aquatic life, human health and overall ecosystem adversely. Therefore, in recent years much emphasis has been given for the use of industrial waste material as low cost adsorbents for removal of metallic contaminants from waste water. Approach: Present study deals with the adsorption equilibrium and kinetics of Cu (II) cation … …American Journal of Applied Sciences, Vol. 8, Issue 3 · 25 Mar 2011 · 7,933 accessesView PDFCite
Research ArticleOpen accessIn the keywordsFlowering and Fruit Set Under Malaysian Climate of Jatropha curcas L.Noor Camellia Noor Alam, Thohirah Lee Abdullah, Nur Ashikin Psyquay AbdullahProblem statement: In recent years Jatropha curcas has drawn the world’s attention as it has the potential to replace fossil fuel as biodiesel. However, the biggest setback in Jatropha cultivation in Malaysia is the low percentage of fruit set and the high ratio of male to female flowers. In order to further understand the flowering and fruit characteristics of Jatropha, … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 1 · 10 Mar 2011 · 9,829 accessesView PDFCite
Research ArticleOpen accessIn the keywordsPhysicochemical and Microbial Caracteristics Performency in Wastewater Treated Under Aerobic ReactorAsma Ben Rajeb, Hamadi Kallali, Neila Saidi et al.Problem statement: The current work study the efficiency of biological wastewater treatment by an aerobic reactor which could be used in small agglomerations. RBC reduced physicochemical and microbiological load of wastewater but values remain above Tunisian standard. Approach: Experiments were conducted on a sand filled PVC column fed with wastewater treated by Rotating Biological Contactor (RBC) at a pulsed rhythm … …American Journal of Environmental Sciences, Vol. 7, Issue 3 · 11 Jul 2011 · 6,676 accessesView PDFCite
Research ArticleOpen accessIn the abstractExtraction Optimization and Antibacterial Property of Total Flavonoids from Zizania Latifolia Bracts and the Effect on Chilled Pork PreservationChen Pan, Shuyi Zhu, Na Niu et al.Zizania latifolia isa widely distributed aquatic vegetable, and its bracts are an agriculturalwaste with a large proportion. In this study, Total Flavonoids of Z. latifoliaBracts (TFZB) were extracted with Ultrasound-Assisted Enzymatic Extraction(UAEE) for the first time, and the extraction process was optimized usingResponse Surface Method (RSM), and compared with other methods. Then, theantibacterial activity of TFZB extracted with optimized UAEE … …American Journal of Biochemistry and Biotechnology, Vol. 18, Issue 3 · 15 Sep 2022 · 6,011 accessesView PDFCite
Research ArticleOpen accessIn the abstractSafe Ulvan Silver Nanoparticles Composite Films for Active Food PackagingHadear Hanie AminProtecting food from the corruption caused by different microbes is a big problem, as we need safe methods for food packaging. In this study, Ulvan (U), edible sulfated polysaccharide extracted from Ulva lactuca, was mediated for the first time non-toxic biosynthesized silver nanoparticles (Ag-NPs) to produce new and safe bio-nanocomposite films called (U/Ag-NPs) films for active food packaging. Ulvan was … …American Journal of Biochemistry and Biotechnology, Vol. 17, Issue 1 · 28 Jan 2021 · 7,740 accessesView PDFCite
Research ArticleOpen accessIn the abstractApplication of ZnO Nano Rods for the Batch Adsorption of Cr(VI): A Study of Kinetics and IsothermsSushma Kamath, Venu Gopal Vishwakarma Ramanjaneyalu, Susmita KamilaThe present study reports the synthesis of nano Zinc Oxide (ZnO) and its adsorption behaviour. The ZnO obtained by precipitation method were found to be well-defined nano rods arranged like flower. The shape, size and structure of ZnO were characterized from X-Ray Diffraction (XRD), Energy Dispersive X-ray (EDX) and Scanning Electron Microscope (SEM) analysis. These nano rods were utilized for … …American Journal of Applied Sciences, Vol. 16, Issue 3 · 12 Apr 2019 · 8,072 accessesView PDFCite
