Polyaniline stabilization of magnetic particles and immobilization of α-amylase
(Belgrade : Association of Chemists and Chemical Engineers of Serbia, 2018)
Magnetic particles (MAG), obtained by standard procedure of coprecipitation of Fe2+ and Fe3+ in an excess of ammonia, and polyaniline modified magnetic particles MAG-PANI were used as carriers for immobilization of α-amylase ...
Effect of chemical composition on microstructural properties and sintering kinetics of (Ba,Sr)TiO3 powders
(Belgrade : ETRAN, 2018)
Barium strontium titanate powders with different Ba:Sr ratios were investigated to determine the influence of the initial composition of powder mixture on microstructural properties and sintering kinetics. It was determined ...
Polyethersulfone/poly(acrylic acid) composite hydrogel membrane reservoirs for controlled delivery of cationic drug formulations
(Elsevier, 2018)
We present the innovative synthesis of polyethersulfone/poly(acrylic acid) composite hydrogel membranes
performed by combining photoirradiation with a traditional liquid phase inversion process.
Fabricated membranes ...
Synthesis and characterization of Na0.4MnO2 as cathode material for aqueous sodium-ion batteries
(Belgrade : Institute of Technical Sciences of SASA, 2018)
The application of rechargeable batteries is growing significantly and there is a need for developing cheaper batteries with good performances. Sodium-ion batteries could be a viable option due to higher abundance of sodium ...
Cross-Linkable Modified Nanocellulose/Polyester Resin-Based Composites: Effect of Unsaturated Fatty Acid Nanocellulose Modification on Material Performances
(Weinheim : WILEY‐VCH Verlag GmbH & Co. KGaA, 2018)
Unsaturated fatty acid (FA)–modified nanocellulose (m-NC) shows potential application in improving mechanical properties of unsaturated polyester/m-NC nanocomposites (UPe/m-NC). A polyester matrix is obtained by polycondensation ...
The fractal nature approach in ceramics materials and discrete field simulation
(ETRAN, 2018)
In this paper, we present experimental data of static fractals and compare the results with theoretical analysis obtained using dynamic particle simulation. The fractal simulator presented in this manuscript is pioneer ...
Primena debeloslojnih segmentiranih termistora za merenje i analizu temperaturnog profila gornjeg sloja zemlje / Application of thick film segmented thermistors for measurement and analysis of ground top layer temperature profile
(Beograd : Savez inženjera i tehničara Srbije, 2018)
A new sensor for measuring ground top layer temperature profile was formed as a row of 40 thermistor segments connected in series, with which the change of temperature in the soil is mesaured and placed on 550 mm depth. ...
Comparative properties of composite poly(lactic-co-glycolic acid)/poly(acrylic acid) implants synthesized using ultraviolet and gamma irradiation
(Belgrade : Institute of Technical Sciences of SASA, 2018)
Composite implants comprising a biodegradable hydrophobic polymer matrix and crosslinked hydrogel with fixed ion exchange groups are promising materials for the construction of controlled drug delivery systems. ...
Compressive strength and microstructure of ordinary cured and autoclaved cement-based composites with mechanically activated kaolins
(Elsevier, 2018)
The effects of two different mechanically activated kaolins, AKV (61% kaolinite, 14% quartz and 16% mica) and AKG (51.6% kaolinite and 40.6% quartz) on the compressive strength of cement composites and microstructure of ...
Mathematical model of the catalytic effect of chromium(VI) on hypochlorite disproportionation in chlorate electrolysis
(Pennington N.J. : Electrochemical Society, 2018)
The effect of chromium(VI) on the kinetics of disproportionation of hypochlorous acid and hypochlorite was established in the solution for the electrolytic production of chlorate. The hexavalent chromium species Cr2O7 2-, ...
