Effects of mechanical activation and two-step sintering on the structure and electrical properties of cordierite-based ceramics
(Elsevier Sci Ltd, Oxford, 2016)
The mechanical activation can help reduce production costs and modify cordierite-based materials. In this study, the structure and electrical properties of the mechanically activated MgO-Al2O3-SiO2 system have been analyzed. ...
The influence of concentration and temperature on the viscoelastic properties of tomato pomace dispersions
(Elsevier Sci Ltd, Oxford, 2016)
The influence of concentration and temperature on the rheological properties of tomato pomace dispersions obtained by rehydration of lyophilized and grinded tomato pomace was investigated in this paper. Examined systems ...
Structural investigation of mechanically activated ZnO powder
(Elsevier Science Sa, Lausanne, 2015)
Commercially available ZnO powder was mechanically activated in a planetary ball mill. In order to investigate the specific surface area, pore volume and microstructure of non-activated and mechanically activated ZnO powders ...
Effect of consolidation parameters on structural, microstructural and electrical properties of magnesium titanate ceramics
(Elsevier Sci Ltd, Oxford, 2016)
The aim of this study is to explore the influence of the processing route on the structural and physical properties of bulk MgTiO3 ceramics. Commercially available MgO and TiO2 powders were mechanically activated in a ...
Weeds shift from generalist to specialist: narrowing of ecological niches along a north-south gradient
(Czech Botanical Soc, Praha 2, 2014)
There are changes in the realized niches of species along environmental gradients, especially at the edge of their distribution where they become more specialized. A classical case is weeds of the Caucalidion alliance that ...
Protein-reinforced and chitosan-pectin coated alginate microparticles for delivery of flavan-3-ol antioxidants and caffeine from green tea extract
(Elsevier Sci Ltd, Oxford, 2015)
In this study, potential interactions of alginate-proteins and proteins-polyphenols were utilized for the formulation of microparticles encapsulating green tea flavan-3-ols and caffeine. Electrostatic assisted extrusion ...
A modified method for assessment of the morphological stage of development as a predictor of alfalfa herbage chemical composition and nutritive value
(Cambridge Univ Press, New York, 2013)
The aim of the current work was to investigate the possibility of modifying the existing mean stage by weight (MSW) system for evaluating the average development stage in alfalfa. The modification was performed with the ...
Hierarchical ZSM-5, Beta and USY zeolites: Acidity assessment by gas and aqueous phase calorimetry and catalytic activity in fructose dehydration reaction
(Elsevier Science Bv, Amsterdam, 2014)
The acidity of hierarchical USY, Beta and ZSM-5 zeolites obtained by alkaline treatment was investigated. Samples were characterized by low temperature nitrogen adsorption, X ray diffraction and solid-state (27)AI MAS NMR. ...
Technical Note: High-resolution mineralogical database of dust-productive soils for atmospheric dust modeling
(Copernicus Gesellschaft Mbh, Gottingen, 2012)
Dust storms and associated mineral aerosol transport are driven primarily by meso- and synoptic-scale atmospheric processes. It is therefore essential that the dust aerosol process and BACKGROUND: atmospheric conditions ...
Influence of mineral matter content on static burning rate of Virginia tobacco from different production areas in Serbia
(Elsevier Science Bv, Amsterdam, 2015)
The aim of this study was to determine the influence of particular element of the minerals complex in Virginia tobacco, from different production areas, on value of static burning rate (SBR). Large leaf tobacco, type ...
