Efficient phytoremediation of uranium mine tailings by tobacco
(Springer-Verlag, 2012)
This investigation shows that tobacco plant roots and leaves accumulate 60 times more uranium than previously reported. Phytoremediation is a convenient technique to clean up polluted soils using herbaceous plants and ...
A coupled thermo-mechanical model of friction stir welding
(Vinca Institute of Nuclear Sciences, 2012)
A coupled thermo-mechanical model was developed to study the temperature fields, the plunge force and the plastic deformations of Al alloy 2024-T351 under different rotating speed: 350, 400, and 450 rpm, during the friction ...
Poly(urethane-siloxane)s based on hyperbranched polyester as crosslinking agent: Synthesis and characterization / Poli(uretan-siloksani) na bazi hiperrazgranatog poliestra kao umreživača - sinteza i karakterizacija
(Serbian Chemical Society, 2012)
A series of novel polyurethane crosslinked structures (PUs) was prepared from α,ω-dihydroxy-(ethylene oxide-poly(dimethylsiloxane)-ethylene oxide) (EO-PDMS-EO), 4,4'-methylenediphenyl diisocyanate and Boltorn ® hyperbranched ...
Quantification of viable spray-dried Lactobacillus plantarum TA and 7A after two years of storage by using real-time PCR
(6th Central European Congress on Food, CEFood 2012, 2012)
Probiotic are "living microorganisms, which upon ingestion in certain numbers, exert health benefits beyond inherent basic nutrition", and it is recommended that probiotic products contain at least 107 live microorganisms ...
Supercritical extraction of essential oil from Mentha and mathematical modelling- the influence of plant particle size
(Elsevier Science Bv, Amsterdam, 2012)
Supercritical CO2 extraction was studied using dried leaves of Mentha, originated from the northern part of Libya. Leaves were milled and sieved to obtain different average particles (d(p) = 0.25 - 0.80 mm). They were ...
Effect of solution pH on crack initiation and propagation in glass-polyester pipes subjected to impact
(Wiley-Blackwell, Hoboken, 2012)
The objective of this study was the determination of the influence of alkaline and acidic solutions on the impact properties of glass-polyester composite pipes. First, the impact test was performed on virgin samples (without ...
Pt supported on nano-tungsten carbide as a beneficial catalyst for the oxygen reduction reaction in alkaline solution
(Elsevier, 2012)
Platinum nanocatalyst at nano-tungsten carbide was synthesized, characterized and tested for oxygen reduction reaction (ORR) in 0.1 mol dm−3 NaOH, at 25 °C. Tungsten-carbide islands on nano-tungsten particles (WC) was ...
Determination of kinetic parameters for the hydrogen evolution reaction on the electrodeposited Ni-MoO2 composite coating in alkaline solution
(Elsevier Science Sa, Lausanne, 2012)
As a result of research on the non-noble metal-based composite electrocatalysts for the hydrogen evolution reaction (HER), the Ni-MoO2 composite coating was produced by electrodeposition from an NH4Cl and NiCl2 containing ...
Damaged welded pipes for oil and gas rigs exposed to internal pressure - Failure estimation
(19th European Conference on Fracture: Fracture Mechanics for Durability, Reliability and Safety, ECF 2012, 2012)
The paper deals with the integrity assessment of API J55 steel casing pipes for drilling rigs, manufactured by high frequency contact welding procedure. The influence of corrosion defects on the pipeline load carrying ...
Relationship between the common optical basicity models and the sulphide capacities of CaO-Al 2O 3-SiO 2-MgO slag
(Slovenska Akademia Vied, 2012)
The correlations between the sulphide capacity and the optical basicity models available in literature are reviewed. The relationship between sulphide capacity and the optical basicity was investigated on plant data collected ...
