EPR study of manganese in Cd1-xMnxS quantum dots
(Materials Science Forum, 2004)
Cd1-xMnxS quantum dots (QDs) with a diameter d less than or equal to 4.5 nm and manganese concentration from x 0.001 to x 0.15 have been prepared using aqueous Solution precipitation. The EPR measurements have been performed ...
Spin interactions in Cd1-xMnxS bulk crystals
(Materials Science Forum, 2005)
Electron paramagnetic resonance (EPR) linewidth in the Cd1-xMnxS bulk crystals with manganese concentrations x = 0.25, 0.33, 0.35 and 0.42 has been studied in the high-temperature region. An analysis of the infinite-temperature ...
Magnetic Properties of Mn-Doped Amorphous SiO2 Matrix
(Acta Physica Polonica A, 2011)
Samples of Mn-doped amorphous SiO2 matrix with manganese concentration 0.7 and 3 at.% have been prepared by a sol-gel method. Transmission electron microscopy analysis has shown that the samples contain agglomerates of ...
Sol-gel as a Method to Tailor the Magnetic Properties of Co1+yAl2-yO4
(Science of Sintering, 2013)
The magnetic properties of mesoscopic materials are modified by size and surface effects. We present a sol-gel method used to tailor these effects, and illustrate it on Co1+yAl2-yO4 spinel. Nanocomposites made of spinel ...
Optical and magnetic properties of Hg1-xMnxSe alloys
(Materials Science Forum, 2005)
In this paper we used X-ray, far-infrared reflectivity and electron paramagnetic resonance measurements to investigate the optical and magnetic properties of Hg1-xMnxSe (x LT = 0.26) alloys. Also, we used different models ...
Room-Temperature Ferromagnetism in Zn-Mn-O, X-Ray Photoemission Surface Study
(Acta Physica Polonica A, 2011)
Room temperature ferromagnetic properties of Zn-Mn-O show evident dependence on manganese concentration and preparation conditions. We systematically studied series of samples with manganese concentration ranging from 0 ...
Computational investigation of cobalt and copper bis (oxothiolene) complexes as an alternative for olefin purification
(Journal of Molecular Modeling, 2020)
Considering that olefins present a large volume feedstock, it is reasonable to expect that their purification is industrially critical. After the discovery of the nickel bis (dithiolene) complex Ni(S2C2(CF3)2)2 that exhibits ...
Effective valorisation of barley bran for simultaneous cellulase and beta-amylase production by Paenibacillus chitinolyticus CKS1: Statistical optimization and enzymes application
(Journal of the Serbian Chemical Society, 2017)
The agricultural raw industry generates large amounts of annually by-products that create disposal problems. Hitherto, there have been no reported papers about the simultaneous production of cellulase and beta-amylase from ...
