Research ArticleOpen accessIn the keywordsElectrical Properties of Novel Lead Zirconate/Synthetic Rubber Composite MaterialsChareumwut Pansa-Ard, Yanee Pornchaisiriarun, Nuchnapa TangboriboonProblem statement: Perovskite lead zirconate exhibits in an orthorhombic formation at a temperature below the Curie temperature, TC. Approach: The orthorhombic is non-centrosymmetric which is capable of spontaneous polarization (electronic, ionic and orientation), depending on their composition and volume fraction. Results: The results from FTIR spectroscopy, XRD patterns, and SEM indicate that the lead zirconate particles are dispersed in Acrylic … …Energy Research Journal, Vol. 2, Issue 2 · 20 Feb 2012 · 7,589 accessesView PDF Cite

Research ArticleOpen accessIn the abstractCurie Point Depth (CPD) Investigation Of Offshore Niger Delta Using High Resolution Aeromagnetic DataOfoha Chimezie Charles, Emujakporue Godwin OmokenuOffshore Niger Delta, Nigeria, is known to be a hub for hydrocarbon exploration within the West Africa region and the world in general. The geologic settings within the Niger Delta province have a proven potential to assist in oil and gas exploration. However, much of the offshore provinces potential remains unknown with respect to the temperature differences using aeromagnetic data. … …Current Research in Geoscience, Vol. 8, Issue 1 · 18 Jan 2019 · 7,811 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEffect of Divalent Ions (A = Ca, Ba and Sr) Substitution in La-A-Mn-O Manganite on Structural, Magnetic and Electrical Transport PropertiesK. P. Lim, S. W. Ng, S. A. Halim et al.Problem statement: Microstructure of the grain will influence the properties of a polycrystalline manganites when different dopant is introduced. In this work, an effort had been made to investigate the influence of Ca, Ba and Sr substitution in La site. Approach: Polycrystalline manganites compound of La0.67A0.33MnO3 where A = Ba, Sr and Ca had been prepared via conventional solid-state reaction … …American Journal of Applied Sciences, Vol. 6, Issue 6 · 30 Jun 2009 · 8,253 accessesView PDF Cite

Research ArticleOpen accessIn the abstractMagnetic Properties and Electrical Resistivity of Zr4+ Substituted Li-Zn FerriteA. A. Sattar, H. M. El-Sayed, W. R. Agami, A. A. GhaniThe effect of Zr-substitution on the physical and magnetic properties of Li0.3+0.5xZn0.4ZrxFe2.3-1.5xO4 ferrites (x=0.0, 0.01, 0.02, 0.03 and 0.05), prepared by the standard ceramic method, has been studied. It is found that the saturation magnetization increases up to x=0.02 and then it decreases. On the other hand, the initial permeability increased while the Curie temperature remained almost constant with increasing … …American Journal of Applied Sciences, Vol. 4, Issue 2 · 28 Feb 2007 · 8,340 accessesView PDF Cite
