Research ArticleOpen accessIn the abstractIdentification, Characterization and Quantification of Elastomeric/Plastomeric Waste for Sustainable Waste MinimizationKajal Yadav, Sangita, A. ChandraThe present study focuses on the importance of characterization of waste/post consumer polymers. In recent years sophisticated instrumental techniques played an important role in identification and characterization of polymers. Advances in computer techniques have been combined with analytical instruments to give analytical speed, resolution and minimal sample requirements unimagined a few years ago. The present study deals with the development … …American Journal of Environmental Sciences, Vol. 1, Issue 3 · 30 Sep 2005 · 7,056 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordPreparation of Fluorine/Silicon Co-Modified Elastic Acrylate with Low Fluorine and High PerformanceYuan Zhihua, Xia Chunlei, Geng Ziye et al.The methyl acrylate was modified with hexafluorobutyl methacrylate (G02) and vinyl triethoxy silane (A-151) as modified monomers, Methyl Methacrylate (MMA) as hard monomer and Butyl Acrylate (BA) as soft monomer. Pre-emulsification, seed emulsion and semi-continuous synthesis process were adopted to the effects of the preparation process, the ratio of G02 and A-151 modified monomers, the amount of soft monomer and … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 1 · 4 Jan 2020 · 7,651 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordEffect of Laser Irradiation on the Structural and Electrical Properties of Co-Zn Ferrite Thin FilmNehad M. TashtoushThin films of irradiated and non-irradiated Co-Zn ferrite was prepared by the thermal evaporation method on a glass substrate. The samples were annealed at 200°C, 400°C and 600°C for 1hr. The XRD analysis of all kinds of films, prepared for this study, shows that the spinel phase is almost completed after annealing. The change of the XRD after annealing is … …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 7,033 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordThermoelectric and Optical Properties of Advanced Thermoelectric Devices from Different Multilayer Thin FilmsMebougna Drabo, Satilmis BudakThermoelectric devices were prepared using different multilayered thin film structures in the order of Ge/Si+Ge, Si+Ge, Si, Sb+Ge, Ge and SiO2/SiO2+Ge by DC/RF Magnetron Sputtering. The thickness of the deposited thin films were measured using Filmetrics UV thickness measurement system. The prepared thermoelectric devices have been modified with 5 MeV Si ions bombardments at the different fluences (doses) using Pelletron … …American Journal of Applied Sciences, Vol. 16, Issue 8 · 29 Aug 2019 · 8,113 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordDurian Husk Properties and its Heating Value EquationPatomsok WilaiponProblem statement: Agricultural residue seems to be one of the most promising energy resources for developing countries. Among the other fruits, durian is a popular one for Thai people. Therefore, a large amount of durian husk is left at the shops or factories. This study was aimed to investigate the characteristics and heating value of durian husk and to develop … …American Journal of Applied Sciences, Vol. 8, Issue 9 · 1 Aug 2011 · 7,856 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordPreparation and Properties of Copolyanhydrides Based on 2-Hexadecylsuccinic Acid and Sebacic AcidYousef Hamdan, Xiangmei Jiang, Kaixun Huang, Kaichao YuPoly(2-hexadecylsuccinic acid-sebacic acid) (P(HSA-SA)) copolymers have been prepared by melt polycondensation. The copolymers were characterized by FT-IR, 1HNMR, gel permeation chromatography (GPC), differential scanning calorimetry (DSC) and thermal gravimetric analysis (TGA). In vitro studies showed that all our prepared copolymers are degradable in phosphate buffer at 37°C. The release profiles of hydrophilic model drug, ciprofloxcin hydrochloride, from the copolymers, follow … …American Journal of Applied Sciences, Vol. 4, Issue 3 · 31 Mar 2007 · 7,427 accessesView PDFCite
