Humidity sensing properties of nanocrystalline pseudobrookite (Fe2TiO5) based thick films
(Elsevier, 2018)
Pseudobrookite based nanopowder was obtained by solid state synthesis of starting hematite and anatase nanopowders in the weight ratio 55:45. Structural and morphological properties were analyzed using X-ray diffraction ...
Deterministic versus Stochastic Analysis of Competitive Adsorption in Equilibrium in Microfluidic Biosensors
(Elsevier, 2018)
We investigate the stochastic sensor response in equilibrium, taking into account competitive adsorption and mass transfer of analyte particles in a microfluidic biosensor chamber. After presentation of the stochastic ...
NiA and NiX zeolites as bifunctional electrocatalysts for water splitting in alkaline media
(Elsevier, 2018)
NiA and NiX zeolites were prepared and characterised using XRD, FTIR and SEM, and subsequently tested as electrodes for hydrogen (HER) and oxygen (OER) evolution reactions in alkaline media. Linear sweep voltammetry and ...
Properties of the cement-based composites with high content of metakaolin
(Dordrecht : Springer, 2018)
Environmental concerns and sustainable development require increased replacement of cement. Most of previous studies have shown that the compressive strength of cement-based composites is maximized with a 20% content of ...
Compressive Strength Improvements of Cement-Based Composites Achieved with Additional Milling of Metakaolin
(Dordrecht : Springer, 2018)
Kaolin from a Serbian deposit, having a high content of mica and quartz, disordered kaolinite and a high specific surface area, was used to prepare metakaolin (MK). The calcination at temperatures of 700 °C or 750 °C for ...
Properties of 3Y-TZP zirconia ceramics with graphene addition obtained by spark plasma sintering
(Elsevier, 2018)
In this study the influence of graphene addition on the microstructure, phase composition, mechanical, and electrical properties of 3Y-TZP ceramics was investigated. Blends of pure 3Y-TZP and with addition of 1 − 4 vol% ...
Electrodeposited AgPd alloy coatings as efficient catalysts for the ethanol oxidation reaction
(Elsevier, 2018)
The Pd and three AgPd alloy layers (AgPd1, AgPd2 and AgPd3) were electrodeposited onto Au disc electrodes from the solution containing high concentration of chloride ions (>12 M). All coatings were investigated by ...
Sintering of alumina doped with different oxides, followed by sensitive dilatometer
(Belgrade : Materials Research Society of Serbia, 2018)
Sintered alumina powder represents suitable material for usage in various industry fields (e.g., as chip carriers in electronics, microwaves, jewelry production), due to convenient physical properties, such as sinterability, ...
Integer codes correcting burst and random asymmetric errors within a byte
(Elsevier, 2018)
In most communication networks, error probabilities 1 → 0 and 0 → 1 are equally likely to occur. However, in some optical networks, such as local and access networks, this is not the case. In these networks, the number 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-, ...
