Research ArticleOpen accessIn the abstractWettability and Interfacial Tension Alteration of Rare-Earth Doped Yttrium Iron Garnet under Influence of Electromagnetic WavesLau Zhen Yin, Lee Kean Chuan, Beh Hoe Guan et al.Yttrium Iron Garnet (YIG) doped with rare-earth elements have shown to alter the magnetic properties of garnet nanoparticles (NPs), which is believed to have direct influence on the wettability, interfacial tension and viscosity alteration of garnet nanofluids. In this study, Y2.8R0.2Fe5O12 (R = Lanthanum (La), Neodymium (Nd) and Samarium (Sm)) NPs were synthesized by using the sol gel auto-combustion method … …American Journal of Applied Sciences, Vol. 16, Issue 6 · 25 Jul 2019 · 7,684 accessesView PDFCite
Research ArticleOpen accessIn the abstractInvestigation of the Characteristics of Thulium Doped Alumina Nanoparticles for Applications in Silica-Based FibersNur Atiqa Bt Rahmat, Hairul Azhar Abd Rashid, H.Y. Wong, Mukter ZamanIt is reported that during the fabrication of doping RE ions into the silica preform, the distribution of particles is inhomogeneous and becomes uneven throughout the fiber which lead to unwanted spectroscopic characteristics. It is assumed that by using thulium doped with alumina, the problem with the inhomogeneity of the particles inside the fiber can be solved. With the incorporation … …American Journal of Applied Sciences, Vol. 14, Issue 1 · 26 Jan 2017 · 7,411 accessesView PDFCite
Research ArticleOpen accessIn the abstractInfluence of Annealing Temperature on Characteristics of Bismuth Doped Zinc Oxide FilmsSirirat Tubsungnoen Rattanachan, Phanuwat Krongarrom, Thipwan FangsuwannarakIn this study, Bismuth (Bi) doped ZnO thin films were deposited on quartz substrates by a sol-gel spin coating method and annealed at different annealing temperatures of 200, 300, 400, 500, 600 and 700°C, respectively. Structural and optical properties of nanocrystalline Bi-doped ZnO film on quartz were investigated by using X-Ray Diffraction (XRD), Scanning Electron Microscope (SEM) and UV-VIS spectrophotometer. … …American Journal of Applied Sciences, Vol. 10, Issue 11 · 1 Oct 2013 · 7,126 accessesView PDFCite
