The influence of the starch coating on the magnetic properties of nanosized cobalt ferrites obtained by different synthetic methods
(Elsevier, 2021)
To investigate the magnetic behavior of starch-coated cobalt ferrites, well-established synthetic methods, i.e., coprecipitation, mechanochemical, ultrasonically assisted coprecipitation, microemulsion, and microwave-assisted ...
Multiferroic Heterostructure BaTiO3/ε-Fe2O3 Composite Obtained by in situ Reaction
(Belgrade : International Institute for the Science of Sintering, 2021)
Solid-state reaction between BaTiO3 and Fe2O3 was used to produce a multiferroic heterostructure composite. Commercial BaTiO3 and Fe(NO3)3•9H2O were suspended in ethanol for 30 minutes in an ultrasound bath. The prepared ...
A CaO/zeolite-based catalyst obtained from waste chicken eggshell and coal fly ash for biodiesel production
(Elsevier, 2020)
The present paper is focused on the development of a new environment-friendly methanolysis catalyst completely
based on waste materials: lignite coal fly ash and chicken eggshells. A novel catalyst based on CaO
supported ...
Chemo- and biocatalytic esterification of marchantin A and cytotoxic activity of ester derivatives
(Elsevier, 2020)
Chemical and biocatalytic synthesis of seven previously undescribed marchantin A ester derivatives has been presented. Chemical synthesis afforded three peresterified bisbibenzyl products (TE1-TE3), while enzymatic method, ...
Influence of Ni2+/Co2+ ratio in electrolyte on morphology, structure and magnetic properties of electrolytically produced Ni−Co alloy powders
(Elsevier, 2020)
Nickel−cobalt (Ni−Co) alloy powders were produced galvanostatically by using sulphate electrolytes with
various ratios of Ni2+/Co2+ (mole ratios). The morphology, phase structure, chemical composition and magnetic
properties ...
Characterisation of the binding of dihydro-alpha-lipoic acid to fibrinogen and the effects on fibrinogen oxidation and fibrin formation
(Elsevier, 2020)
A reduced form of the alpha-lipoic acid, dihydro-alpha-lipoic acid (DHLA) is a potent, naturally occurring antioxidant which can be consumed as food constituent or as supplement at doses up to 600 mg/day. DHLA has inhibitory ...
TiO2/APTES cross-linked to carboxylic graphene based impedimetric glucose biosensor
(Elsevier, 2020)
Herein, we proposed a novel approach and state-of-the-art technology for the improvement of the materials and
enzyme immobilization at the electrode surface and construction of impedimetric glucose biosensor. We ...
Structural, optical and photocatalytic properties of LaTi0.4Mg0.4Fe0.2O3 perovskite prepared by high-energy ball milling
(Elsevier, 2021)
The LaTi0.4Mg0.4Fe0.2O3 perovskite was synthesized using a mechanochemical process followed by high-temperature annealing at 600 and 800 °C. The effects of milling time and annealing temperature on structural, microstructural ...
X-rаy diffraction and SEM analysis of waste sulfur modification for use in concretes
(University of Belgrade - Faculty of Mining and Geology, 2021)
Secondary sulfur obtained as a by-product in the oil refining process is a major problem as an environmental pollutant. One of the possibilities for environmental protection is the use of sulfur obtained in this way as a ...
Light-transmitting Measurements through Starch-coated Cobalt Ferrite Ferrofluids Exposed to an External Magnetic Field
(Springer, 2021)
The light-transmitting measurements at the 655 nm wavelength were performed through starchcoated cobalt ferrite ferrofluids synthesized by well-established synthetic methods, i.e., coprecipitation, mechanochemical, ...
