Magnetism and Antiferroelectricity in MgB6
(Amer Physical Soc, College Pk, 2012)
We report on a density functional theory study demonstrating the coexistence of weak ferromagnetism and antiferroelectricity in boron-deficient MgB6. A boron vacancy produces an almost one dimensional extended molecular ...
Structural, ferroelectric and magnetic properties of BiFeO3 synthesized by sonochemically assisted hydrothermal and hydro-evaporation chemical methods
(Elsevier Sci Ltd, Oxford, 2016)
BiFeO3 powders were synthesized by sonochemically assisted hydrothermal and hydro-evaporation methods. The X-ray diffraction confirmed the presence of secondary phases, Bi25FeO39 and Bi2Fe4O9, in as prepared BiFeO3 powders. ...
Magnetic properties of NiMn2O4-delta (nickel manganite): Multiple magnetic phase transitions and exchange bias effect
(Elsevier Science Sa, Lausanne, 2014)
We present magnetic properties of NiMn2O4-delta (nickel manganite) which was synthesized by complex polymerization synthesis method followed by successive heat treatment and final calcinations in air at 1200 degrees C. The ...
Improved electrical properties of Nb doped BaCe0.9Y0.1O2.95 electrolyte for intermediate temperature SOFCs obtained by autocombustion method
(Elsevier Science Sa, Lausanne, 2014)
Nb doped BaCe0.9Y0.1O2.95 (BCY) powders were synthesized by both solid state reaction (SSR) and autocombustion reaction (ACR) method to investigate how different synthesis routes influence the properties of the powders and ...
Avarol derivatives as competitive AChE inhibitors, non hepatotoxic and neuroprotective agents for Alzheimer's disease
(Elsevier France-Editions Scientifiques Medicales Elsevier, Issy-Les-Moulineaux, 2016)
Avarol is a marine sesquiterpenoid hydroquinone, previously isolated from the marine sponge Dysidea avara Schmidt (Dictyoceratida), with antiinflammatory, antitumor, antioxidant, antiplatelet, anti-HIV, and antipsoriatic ...
Immobilization of hexavalent chromium by fly ash-based geopolymers
(Elsevier Sci Ltd, Oxford, 2017)
In this paper the immobilization of hexavalent chromium (Cr (VI)) by fly ash (FA)-based geopolymers was investigated, depending on FA characteristics, mechanical activation of FA, geopolymer synthesis conditions and ...
External sulfate attack on alkali-activated fly ash-blast furnace slag composite
(Elsevier Sci Ltd, Oxford, 2017)
Reliable durability testing of alkali-activated binders, which might serve as a basis for the prediction of long-term field performance, is one of the main challenges towards broader commercial applications of AAB. This ...
Electrochemical oxidation of ethanol on palladium-nickel nanocatalyst in alkaline media
(Elsevier, Amsterdam, 2016)
Pd-Ni/C catalyst was synthesized employing a borohydride reduction method. The high area Ni was first dispersed on the carbon support and then modified by Pd nanoparticles. Transmission electron microscopy confirmed ...
Parenchyma cell wall structure in twining stem of Dioscorea balcanica
(Springer, Dordrecht, 2017)
Anatomical adaptation of liana plants includes structural changes in cell walls of different tissues: fibers, vessel elements and tracheids. However, the contribution of parenchyma cells to stem twining in liana plants is ...
Photo-redox reactions of indole and ferric iron in water
(Elsevier, Amsterdam, 2016)
Iron-organic interactions are involved in a variety of environmental phenomena, including photo-redox reactions, iron cycling and bioavailability, as well as contaminant fate. In this study we examined UV-induced redox ...
