Research ArticleOpen accessIn the abstractDetermination of Scattering Parameters of a New Copolymer by Using a Laser Scattering MethodRiyad GhazyProblem statement: In present work a poly (4 vinylphenol-co-2 hydroxethyl methacrylate) polymer, (PVPh-HEM), was selected, as a new copolymer, to study the phenomena of Optical Laser Light Scattering (OLLS). Approach: A poly (4 vinylphenol-co-2 hydroxethyl methacrylate) was investigated for its importance in the highly industrial applications in different branches. This polymer was solved in two different solvents like as Methanol … …American Journal of Applied Sciences, Vol. 8, Issue 6 · 13 Jun 2011 · 6,923 accessesView PDFCite
Research ArticleOpen accessIn the abstractSynthesis and Characterization of Silver/Polyvinilpirrolidone (Ag/PVP) Nanoparticles Using Gamma Irradiation TechniquesShawkat Salameh Gasaymeh, Shahidan Radiman, Lee Yook Heng et al.Problem statement: In this study, attempts had been made to synthesize silver (Ag)/Poly Vinylpyrolidone (PVP) nanoparticles by ionizing radiation and at the same time overcoming some of the disadvantages previously reported by other methods such as impurities, solvent toxicity, size and distribution control and difficulty in their preparation that limits their commercialization potential. Approach: The use of this alternative method … …American Journal of Applied Sciences, Vol. 7, Issue 7 · 31 Jul 2010 · 9,962 accessesView PDFCite
