Effect of boric acid on the porosity of clay and diatomite monoliths
(Elsevier Sci Ltd, Oxford, 2016)
Porous silica ceramics were obtained at low forming pressure (40-80 MPa) and low sintering temperature (850-1300 degrees C) for 4 h in air. Boric acid was used as a low-cost additive, in the amount of 2 wt%. Relatively ...
Engineered surface waves in hyperbolic metamaterials
(Optical Society of America, 2013)
We analyzed surface-wave propagation that takes place at the boundary between a semi-infinite dielectric and a multilayered metamaterial, the latter with indefinite permittivity and cut normally to the layers. Known ...
Anodic luminescence, structural, photoluminescent, and photocatalytic properties of anodic oxide films grown on niobium in phosphoric acid
(Elsevier, 2015)
This article reports on properties of oxide films obtained by anodization of niobium in phosphoric acid before and after the dielectric breakdown. Weak anodic luminescence of barrier oxide films formed during the anodization ...
Formic Acid Oxidation at Platinum-Bismuth Clusters
(Electrochemical Soc Inc, Pennington, 2014)
Formic acid oxidation was studied on platinum-bismuth deposits on glassy carbon (GC) substrate. The catalysts of equimolar ratio were prepared by potentiostatic deposition using chronocoulometry. Bimetallic structures ...
A study of the structural and morphological properties of Ni-ferrite, Zn-ferrite and Ni-Zn-ferrites functionalized with starch
(Elsevier Sci Ltd, Oxford, 2018)
Zinc-ferrite, nickel-ferrite and mixed nickel-zinc ferrites were successfully synthesized via the thermal decomposition method from acetylacetonate complexes. To control the particle size and enhance dispersibility in an ...
Edible blend films of pectin and poly(ethylene glycol): Preparation and physico-chemical evaluation
(Elsevier, 2018)
The aim of this study was the development of novel polysaccharide based films intended to be used as edible food packaging material. The films were prepared by solution casting method using highly methoxylated pectin (PEC) ...
Decolorization of reactive textile dyes using water falling film dielectric barrier discharge
(Elsevier, 2011)
Decolorization of reactive textile dyes Reactive Black 5, Reactive Blue 52, Reactive Yellow 125 and Reactive Green 15 was studied using advanced oxidation processes (AOPs) in a non-thermal plasma reactor, based on coaxial ...
Silver incorporation on viscose and cotton fibers after air, nitrogen and oxygen DBD plasma pretreatment
(Springer, Dordrecht, 2013)
Dielectric barrier discharge (DBD) pretreatments in air, nitrogen and oxygen plasma of viscose and cotton fabrics with subsequent immobilization of silver were studied. Surface activation of treated fibers was evaluated ...
Kinetics of sunflower and used vegetable oil methanolysis catalyzed by CaO center dot ZnO
(Elsevier Sci Ltd, Oxford, 2013)
The kinetics of heterogeneous methanolysis of sunflower oil and used vegetable oil were studied at different temperatures, ranging from 60 to 96 degrees C using CaO center dot ZnO as catalyst (2 wt% on the basis of oil) ...
Structural, photoluminescent and photocatalytic properties of TiO2:Eu3+ coatings formed by plasma electrolytic oxidation
(Elsevier, 2016)
In this paper, we used plasma electrolytic oxidation (PEO) of titanium in water solution containing 10 g/L Na3PO4 center dot 12H(2)O + 2 g/L Eu2O3 powder for preparation of TiO2:Eu3+ coatings. The surfaces of obtained ...
