Synthesis of core-shell hematite (α-Fe2O3) nanoplates: Quantitative analysis of the particle structure and shape, high coercivity and low cytotoxicity
(Applied Surface Science, 2017)
Hematite core-shell nanoparticles with plate-like morphology were synthesized using a one-step hydrothermal synthesis. An XRPD analysis indicates that the sample consist of single-phase α-Fe2O3 nanoparticles. SEM and TEM ...

(Belgrade : Institute of Physics Belgrade, 2017)
There is a great technological interest in synthesis of lanthanide doped upconverting nanoparticles with specific morphological characteristics and efficient luminescence response suitable for biomedical use [1]. A ...
Biodegradation of cotton and cotton/polyester with Ag/TiO2 nanoparticles in soil
(Elsevier Sci Ltd, Oxford, 2017)
This study discusses the biodegradation behavior of cotton and cotton/PET fabrics impregnated with Ag/TiO2 nanoparticles in soil. Biodegradation behavior was evaluated by standard test method ASTM 5988-03 based on determination ...
Degradation behaviour of PCL/PEO/PCL and PCL/PEO block copolymers under controlled hydrolytic, enzymatic and composting conditions
(Elsevier Sci Ltd, Oxford, 2017)
Short-term hydrolytic and enzymatic degradation of poly(epsilon-caprolactone) (PCL), one series of triblock (PCL/PEO/PCL) and the other of diblock (PCL/PEO) copolymers, with a low content of hydrophilic PEO segments is ...
Oxidized pentacene micro-rods obtained by thermal annealing of pentacene thin films in air
(Pergamon-Elsevier Science Ltd, Oxford, 2017)
Prolonged annealing of pentacene thin films in air leads to the formation of nano- and micro-scale rod-shaped structures at temperatures equal to or higher than 130 degrees C. Scanning electron microscopy measurements ...
Dependence of Structural Characteristics of Polyamide Textured Yarns on the Parameters of the False Twist Yarn Texturing Process
(Inst Chemical Fibres, Lodz, 2017)
In the false twist texturing process, due to the action of mechanical forces and heat, a disorientation of structural elements happens at all levels of the supramolecular structure. These changes are related to changes in ...
Advances in mathematical modeling of supercritical extraction processes
(Mathematical Research Summaries, 2017)
A new trend in mathematical modeling of supercritical extraction process from plant material is presented. The most of the previously published models considered properties of the fixed bed of plant material during the ...
Designing of manufacturing process of reformer integrated in system with HTPEM fuel cell stack
(Belgrade : Faculty of Mechanical Engineering, Innovation Center, 2017)
In this paper is shown designing of manufacturing process of reformer in polymeric electrolyte membrane
(PEM) fuel cell. The process is based on reformer modelling, analyzing of reforming initial geometry and
change of ...
Mechanism of adsorption of Cu2+ and Zn2+ on the corn silk (Zea mays L.)
(Elsevier, Amsterdam, 2017)
In this study the novel biosorbent - raw corn silk (CS) was investigated for Cu2+ and Zn2+ removal from aqueous solutions. The physical and chemical properties of CS were determined by SEM - EDX and ATR - FTIR techniques. ...
Structural, Chemical and Magnetic Properties of Nickel Vertical Posts Obtained by Glancing Angle Deposition Technique
(Science of Sintering, 2017)
In this work, Glancing Angle Deposition technique was used for obtaining nanostructured nickel thin film with vertical posts on glass substrate which was positioned 75 degrees with respect to the substrate normal and rotated ...
