Sintesis dan Karakterisasi Material Nano-Perovskite Neodymium Iron Oxide (NdFeO3)

Analisis dan Sintesis Sinyal Suara

Audio signal information with high quality would help the television audience to increase the perception of the information displayed. Transmission channel capacity will become limited, while the need of channel communication is increased. The research aim is coding the audio signal on the low bit rate for saving the channel communication usage for digital television broadcasting. The research ...

Metal Ions Removal Using Nano Oxide Pyrolox™ Material

The paper presents the use of Pyrolox™ containing manganese nano oxides used for the removal of Cu(II), Zn(II), Cd(II), and Pb(II) as well as U(VI) ions. Their concentrations were analyzed using the atomic absorption spectrometer SpectrAA 240 FS (Varian) as well as UV-vis method. For this purpose the static kinetic and equilibrium studies were carried out using the batch technique. The effect o...

Manganese Oxide Promoted LaCoO3 Nano-Perovskite for Oxidation of a Model Exhaust Gas

Chemical Synthesis and Characterization of Perovskite NdfeO3 Nanocrystals via a Co-Precipitation Method

A facile co-precipitation method for the synthesis of well-dispersed NdFeO3 nanocrystals is developed in the presence of octanoic acid as surfactant. Co-precipitation can produce fine, high-purity, stoichiometric particles of single and multicomponent metal oxides. The product is characterized by Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), scanning electron microsc...

SYNTHESIS, CHARACTERIZATION AND NEUROTOXIC EFFECT OF SCHIFF BASE LIGANDS AND THEIR COMPLEXES (Sintesis, Pencirian dan Pengaruh Nurotoksik Bes Schiff dan Kompleksnya)

Two ligands and eight complexes are successfully synthesized by reacting 1,8-diaminonapthelene with aldehyde/ketone derivatives in 1:2 ratio for ligand formation and 1:1 ratio for complex formations. The compounds are characterized through CHN elemental anaysis, IR spectroscopy, H NMR spectroscopy, melting point and magnetic susceptibility determination. The neurotoxicity of compounds is evalua...
