The influence of heating rates and environment conditions on the thermal behaviour of two cobalt basic salts,β-Co2(OH)3Cl and Co5(OH)Cl H2O, have been studied. The processes were followed using thermogravimetric and differential thermal analysis, X-ray diffraction, and infrared spectroscopy. When decomposition reactions are carried out in a nitrogen atmosphere, Co3O4 is Cited by: A series of cobalt-free alloys was selected for evaluation based on the available knowledge of wear and galling behavior of austenitic iron-base alloys. The experimental alloys were evaluated for galling resistance and for adhesive wear resistance in a crossed cylinder wear test in more» both air and deionized water environments at room.
Lanthanum cobaltite (LaCoO3) perovskite-type oxide is an important conductive ceramic material finding a broad range of technical applications. Physical and chemical properties of the final lanthanum cobalt oxide powder material obtained are strongly dependent on the method of preparation. Taking in account these considerations, we focus our investigation on the solid state reaction by: 2. A series of coprecipitated nickel(II)–cobalt(II) hydroxide nitrate samples with different cationic compositions has been studied by means of X-ray diffraction, infrared spectroscopy and thermal analysis.A continuous series of solid solutions Ni x Co 2–x (OH) 3 NO 3 (0⩽x⩽2) is formed between the end members Ni 2 (OH) 3 NO 3 and Co 2 (OH) 3 NO observed changes in the IR spectra.

The term thermistor is a contraction of the words “thermal” and “resistor”. All resistors have some dependency on temperature, which is described by their temperature coefficient. In most cases for (fixed or variable) resistors the temperature coefficient is minimized, but in the case of thermistors a high coefficient is achieved.

2 Magnetic behaviour of cobalt in (GdxY1-x)n+1Co3n+5B2n compounds crossing the situation when there is a collapse (or inset) of the ordered cobalt moments [1–5]. The cobalt moments are generally dependent on the lattice sites where they are located.
By magnetic measurements only their mean values can be obtained. The electrotransport behaviour of Co, Fe and Cr in beta -zirconium from K to K was investigated. The radioactive tracer technique was used in. In this work, the isonicotinamide was coordinated to the Cobalt ion in oxidation state +2.
The relevance of this work is the investigation of the in vitro bactericidal potential of the synthesized complex when tested in Gram-positive and negative bacteria strains. This study is motivated by the need to obtain new materials that have antibiotic properties and that, in the future, may become an Author: Anderson Dourado Galvão, Fabricio Tarso de Moraes, Claudia Cristina de Sousa, Kátia Meirelles Duarte.

Abstract. Some new cadmium (II) and mercury (II) halides complexes of the bidentate Schiff base ligand N,N-bis [(E)(2-nitrophenyl)allylidene)]benzene-1,2-diamine (L) were synthesized, and characterized by physical and spectral study such as elemental analysis, molar conductance, UV–visible spectra, FT-IR spectra, 1 H NMR and 13 C NMR spectra.
All complexes were stable in DMF solvent and. Journal of Thermal Analysis and Calorimetry Print ISSN: The thermal behaviour of the compounds has been studied using thermogravimetry and differential thermal analysis.
An intermediate compound is observed in the decomposition of the cobalt complex. Co adipate, Co(C 6 H 8 O 4), has been found to order near 10 K into a magnetic structure featuring sheets of tetrahedral Co cations coupled antiferromagnetically in two dimensions through carboxylate emergence of this order is accompanied by magnetoelastic coupling, which drives anisotropic negative thermal expansion along the a-axis below 50 K, the first time such behaviour has.
