SiC Synthesis Using Natural Mg-Silicates
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2012)
The silicon carbide powders are prepared by carbothermal reduction of domestic mineral resources (white and brown sepiolite), at relatively low temperatures (1200 - 1600 degrees C). Carbothermal reduction process is greatly ...
Electrochemical oxidation of methanol on Pt/(RuxSn1-x)O-2 nanocatalyst
(Srpsko hemijsko društvo, Beograd, 2013)
Ru-doped SnO2 powder, (RuxSn1-x)O-2, with a Sn:Ru atomic ratio of 9:1 was synthesized and used as a support for Pt nanoparticles (30 mass % loading). The (RuxSn1-x)O-2 support and the Pt/(RuxSn1-x)O-2 catalyst were ...
Nest-site preference of griffon vulture (gyps fulvus) in Herzegovina
(Srpsko biološko društvo, Beograd, i dr., 2012)
Although formerly an abundant species, the Eurasian Griffon (Gyps fulvus Hablizl, 1783) has undergone a dramatic decline in Herzegovina. Such an unfavorable trend may be associated with frequent poisoning incidents ...
Electrodeposition and characterization of Ni-MoO2 composite coatings as cathodes for the hydrogen evolution reaction in alkaline solution
(Srpsko hemijsko društvo, Beograd, 2013)
Composite Ni-MoO2 coatings were prepared and characterized with respect to their possible application as electrocatalysts for the hydrogen evolution reaction (HER) in alkaline solution. The composites were electrodeposited ...
Effects of mixed saline and alkaline stress on the morphology and anatomy of pisum sativum l.: the role of peroxidase and ascorbate oxidase in growth regulation
(Srpsko biološko društvo, Beograd, i dr., 2013)
The effects of hyperalkaline, thermo-mineral water from Slatina on the morphology and anatomy of pea plants (Pisum sativum L.), were examined after eleven days of treatment with a mixture of tap water and Slatina water in ...
The influence of substituted aromatic aldehydes on the electrodeposition of Zn-Mn alloy
(Srpsko hemijsko društvo, Beograd, 2013)
Additives are necessary in the electrodeposition of Zn-Mn alloys at high current densities, in order to reduce the hydrogen evolution reaction and prevent dendrite formation. The influences of two aromatic aldehydes, ...
Effect of long-term cyanide exposure on cyanide-sensitive respiration and phosphate metabolism in the fungus phycomyces blakesleeanus
(Srpsko biološko društvo, Beograd, i dr., 2014)
The effects of long-term exposure (5 h) of Phycomyces blakesleeanus mycelium to 5 mM KCN on respiration and phosphate metabolites were tested. Exposure to cyanide, antimycin A and azide lead to a decrease in the activity ...
Selection and rapd analysis of pseudomonas ssp. Isolates able to improve biological viability of potato seed tubers
(Društvo genetičara Srbije, Beograd, 2013)
Indoleacetic acid (IAA) producing Pseudomonas isolates from the rhizosphere of maize (Q4 and Q20), alfalfa (Q1 and Q16) and wild red clover (B25) were selected for the investigation of their effect on the biological vitality ...
The sorption of inorganic arsenic on modified sepiolite: the effect of hydrated iron(III) oxide
(Srpsko hemijsko društvo, Beograd, 2014)
The sorption of inorganic arsenic species, As(III) and As(V), from water by sepiolite modified with hydrated iron(III) oxide was investigated at 25 degrees C through batch studies. The influence of the initial pH value, ...
Characterization of the Alkoxide-based Sol-gel Derived La9.33Si6O26 Powder and Ceramic
(Slovensko Kemijsko Drustvo, Ljubljana, 2014)
In this study, we report on the acid-catalysed synthesis of La9.33Si6O26 from lanthanum nitrate or acetate and silicon ethoxide (TEOS) in the ethanol solvent, upon the transition from liquid to amorphous and crystalline ...
