Research ArticleOpen accessIn the author namesSynthesis 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
Research ArticleOpen accessIn the author namesGamma Irradiation Synthesis and Influence the Optical and Thermal Properties of Cadmium Sulfide (CdS)/Poly (Vinyl Pyrolidone) NanocompositesShawkat Salameh Gasaymeh, Shahidan Radiman, Lee Yook Heng, Elias SaionProblem statement: Gamma irradiation has been successfully used to prepare a spherical cadmium sulfide CdS/Poly Vinylpyrolidone (PVP) quantum dots nanoparticles with enhancement of their optical band gap energy and thermal properties at room temperature and under ambient pressure. Sodium thiosulfate was used as a sulfur source in an aqueous solution. The formation of lower band gap energy of CdS/PVP nanoparticles … …American Journal of Applied Sciences, Vol. 7, Issue 4 · 30 Apr 2010 · 8,459 accessesView PDFCite
Research ArticleOpen accessIn the author namesPreparation of WO3 Nanoparticles Using Cetyl Trimethyl Ammonium Bromide Supermolecular TemplateNilofar Asim, S. Radiman, M. Ambar bin YarmoProblem statement: WO3 is one of the most interested metal oxides because of its application as catalysts, sensors, electrochromic devices, ceramic, solar cell, pigments and so on. More investigation is needed to find the good and low cost method for preparation of WO3 nanoparticles with uniform morphology and narrow distribution using a surfactant mediated method. Approach: In this study, the … …American Journal of Applied Sciences, Vol. 6, Issue 7 · 31 Jul 2009 · 7,699 accessesView PDFCite
