We investigated the effect of magnetic doping on magnetic and transport properties of Bi2Te3thin films. CrxBi2−xTe3 thin films with x = 0.03, 0.14, and 0.29 were grown epitaxially on mica substrate with low surface roughness (∼0.4 nm). It is found that Cr is an electron acceptor in Bi2Te3 and increases the magnetization of CrxBi2−xTe3. When x = 0.14 and 0.29,ferromagnetism appears in CrxBi2−xTe...

Herein, we report, for the first time, synthesis, characterization, and photocatalytic methyl blue dye degradation performance of magnesium oxide (MgO) nanoparticles (NPs) synthesized by a facile green approach using Camellia sinensis (tea leaves) extract as reducing agent. The as-prepared materials were characterized X-ray diffraction (XRD), which confirmed large-scale synthesis well crystalli...

In this work, the impact of nonstoichiometric substitution Fe3+ cations by Ni2+ ones on structural and magnetic properties Co0.5Ni0.5+xFe2−xO4 nanoferrites (0.0 ≤ x 0.4) synthesized citric autocombustion method has been investigated. The single cubic phase for samples sintered at 600 °C was verified XRD patterns FTIR spectra. crystallite size microstrain were deduced using Williamson-Hall metho...

This paper presents the characterization of a secondary cone crusher concave liner made Hadfield steel used in Chilean mining after crushing copper minerals during all service life. During use, suffers indentation (cold working) and abrasion; this combination provides with layer that constantly renews itself, maintaining surface highly resistant to abrasive wear. The results presented here were...

We propose a novel theory of self-fulfilling fluctuations in the labor market. A firm employing an additional worker generates positive externalities on other firms, because employed workers have more income to spend and have less time to shop for low prices than unemployed workers. We quantify these shopping externalities and show that they are sufficiently strong to create strategic complemen...
