Structural and phase composition modification of nanocrystalline Nd14Fe79B7 alloy during thermomagnetic measurements
(Technical Faculty, Bor, 2009)
Changes in the microstructure parameters, phase composition and magnetic properties of rapid quenched Nd-rich Nd14Fe79B7 alloy caused by thermomagnetic measurement (TM) were studied using XRD methods of phase analysis, ...
Study of Nd-Fe-B alloys with nonstoichiometric Nd content in optimal magnetic state
(International Institute for the Science of Sintering, Beograd, 2009)
Characterization of two rapid-quenched Nd-Fe-B alloys with nonstoichiometric Nd content in the optimized magnetic state was carried out using the X-ray diffractometry (XRD), 57Fe Mössbauer spectroscopic phase analysis (MS), ...
A comparative thermomagnetic study of melt-spun Nd-Fe-B alloys with different Nd content
(International Institute for the Science of Sintering, Beograd, 2009)
Changes in the phase composition and magnetic properties of three types of commercial Nd-Fe-B alloys with different Nd content - low (10-12 wt%), near stoichiometric (21-25 wt%) and rich (26-29 wt%) caused by thermomagnetic ...
Characterization and Morphology of Copper Powder Particles as a Function of Different Electrolytic Regimes
(Esg, Belgrade, 2010)
The effect different deposition regimes (constant and reversing currents), on the powdered copper electrodeposits morphology were investigated. The results obtained in constant regimes were compared with those obtained in ...
The Dynamic Change of Vegetation Cover and Associated Driving Forces in Nanxiong Basin, China
(MDPI, 2017)
Natural climate change and human activities are the main driving forces associated with vegetation coverage change. Nanxiong Basin is a key ecosystem-service area at the national level with a dense population and highly ...
Microstructure refinement and physical properties of Ag-SnO2 based contact materials prepared by high-energy ball milling
(International Institute for the Science of Sintering, Beograd, 2013)
High energy ball milling was used in order to improve dispersion of metal oxide in Ag-SnO2 electrical contact materials. The processed Ag-SnO2 (92:8) and Ag-SnO2In2O3 (87.8:9.30:2.9) powder mixtures were subsequently ...
Synthesis, Spectral and Solid State Characterization of a New Bioactive Hydrazine Bridged Cyclic Diphosphonium Compound
(MDPI, 2012)
The facile preparation of a racemic hydrazine bridged diphosphonium compound possessing a ring system analogous to bicyclo[3.3.2]decane is reported. Although the reaction yield is low, the structure of the compound, which ...
LC/DAD analysis of serum biogenic amines in patients with diabetes mellitus, chronic urticaria and Hashimoto's thyroiditis
(Wiley-Blackwell, Hoboken, 2012)
Simultaneous enhancement of natural sunlightand artificial UV-driven photocatalytic activity of a mechanically activated ZnO/SnO2 composite
(The Royal Society of Chemistry, 2017)
Mechanical milling of commercial ZnO and SnO2 was used to produce a ZnO/SnO2 composite with a high density of surface defects; in particular, zinc interstitials (Zni) and oxygen vacancies (VO). To determine the impact of ...
The predicted infrared spectrum of the hyperberyllium molecule BeOBe in its (X)over-tilde(1)Sigma(+)(g) and (a)over-tilde(3)Sigma(+)(u) electronic states
(Academic Press Inc Elsevier Science, San Diego, 2010)
Hypermetallation is a concept that applies to molecules having metal stoichiometries that exceed normal valence, and BeOBe is just one example of such a molecule. Previous ab initio calculations and spectroscopic studies ...
