Preparation of highly conductive carbon cryogel based on pristine graphene
(Elsevier Science Sa, Lausanne, 2012)
In this paper we report fabrication and characterization of highly conductive carbon cryogel. The carbon cryogels were prepared by the sol-gel polymerization of resorcinol and formaldehyde in an aqueous surfactant stabilized ...
Enthalpy-entropy compensation for n-hexane adsorption on HZSM-5 containing transition metal ions
(Academic Press Ltd- Elsevier Science Ltd, London, 2012)
In this work, the values of entropy changes related to n-hexane adsorption onto ion-exchanged ZSM-5 zeolites were calculated from differential heats, obtained from microcalorimetric experiments. The existence of enthalpy-entropy ...
Antioxidative activities and chemical characterization of polysaccharide extracts from the widely used mushrooms Ganoderma applanatum, Ganoderma lucidum, Lentinus edodes and Trametes versicolor
(Academic Press Inc Elsevier Science, San Diego, 2012)
Antioxidant activities of polysaccharide extracts of four of the most widely known mushrooms often used in medicinal applications as well as in tea and food, namely Ganoderma applanatum, Ganoderma lucidum, Lentinus edodes ...
Interpretation of hybrid x sowing date interaction for oil content and oil yield in sunflower
(Elsevier, Amsterdam, 2012)
Due to the presence of an interaction, it is often difficult to recommend which sunflower hybrids should be planted based on specific sowing dates or production regions. Through this study, the hybrid x sowing date (H x ...
Microstructural properties of electrochemically prepared Ni-Fe-W powders
(Elsevier Science Sa, Lausanne, 2012)
A nanostructured Ni-Fe-W powder was obtained by electrodeposition from ammonium citrate electrolyte within the current density range of 500-1000 mA cm(-2) at the electrolyte temperature of 50 degrees C -70 degrees C. XRD ...
Rhizome and root yield of the cultivated Arnica montana L., chemical composition and histochemical localization of essential oil
(Elsevier, Amsterdam, 2012)
Arnica montana (L) is a medicinal plant whose flower heads are widely used for the topical treatment of bruises and sprains in phytopharmaceutical preparations. Despite being cultivated for flower heads production for a ...
Encapsulation of thyme (Thymus serpyllum L.) aqueous extract in calcium alginate beads
(Wiley, Hoboken, 2012)
BACKGROUND: Encapsulation of Thymus serpyllum L. aqueous extract within calcium alginate beads was studied in order to produce dosage formulations containing polyphenolic compounds. Electrostatic extrusion was applied for ...
Effectiveness assessment of agricultural machinery based on fuzzy sets theory
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
The quality of service of agricultural machinery represents one of the basic factors for successful agricultural production. In this sense, there is a clear need for defining the exact indicator of the quality of these ...
Influence of mechanochemical activation on the sintering of cordierite ceramics in the presence of Bi2O3 as a functional additive
(Elsevier, Amsterdam, 2012)
Due to its outstanding electrical characteristics, such as the low temperature expansion coefficient, low dielectric constant and good mechanical properties, cordierite, 2MgO center dot 2Al(2)O(3)center dot 5SiO(2), is a ...
Exploring diversity of Erwinia amylovora population in Serbia by conventional and automated techniques and detection of new PFGE patterns
(Springer, Dordrecht, 2012)
Forty Erwinia amylovora strains originating from different host plants and locations in Serbia and one strain from Montenegro were characterized by conventional, automated and molecular techniques. All strains were ...
