Volumetric Properties and Spectroscopic Studies of Pyridine or Nicotine Solutions in Liquid Polyethylene Glycols
(Amer Chemical Soc, Washington, 2011)
Densities and molar excess volumes of the solutions of pyridine or nicotine in liquid polyethylene glycol, PEG200 and PEG400, have been determined at several temperatures. The experimental molar excess volumes are negative, ...
An overview of encapsulation technologies for food applications
(Elsevier Science Bv, Amsterdam, 2011)
Encapsulation is a process to entrap active agents within a carrier material and it is a useful tool to improve delivery of bioactive molecules and living cells into foods. Materials used for design of protective shell of ...
Electrochemically synthesized polyaniline as support for lipase immobilization
(Elsevier Science Bv, Amsterdam, 2011)
Electrochemical synthesis of polyaniline support for enzyme immobilization provides easier control over the properties of obtained polymer and reduced risk of biocatalyst inactivation with residues of toxic compounds. In ...
Synthesis and characterization of silver/poly(N-vinyl-2-pyrrolidone) hydrogel nanocomposite obtained by in situ radiolytic method
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
This work describes radiolytic synthesis of silver nanoparticles (Ag NPs) within the poly(N-vinyl-2-pyrrolidone) (PVP) hydrogel. The hydrogel matrix was obtained by gamma irradiation-induced cross-linking, while the in ...
Determination of fatigue crack growth parameters in welded joint of HSLA steel / Određivanje parametara zamornog rasta prsline kod zavarenih spojeva od HSLA čelika
(Society for Structural Integrity and Life, Institute for Material Testing, 2011)
The structural integrity and operational safety of welded pressure vessels primarily depends on the behaviour of weldments. In spite of all efforts in material production and improvements in welding techniques, including ...
The formation of oxide nanoparticles on the surface of natural clinoptilolite
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
Nanoparticles of NiO, ZnO and Cu(2)O crystallize when the Ni-, Zn- and Cu-exchanged natural clinoptilolite, respectively, are dehydrated by heating in air at 550 degrees C. The dehydration of Mn-exchanged clinoptilolite ...
Structural Integrity Assessment of Welded Pressure Vessel Produced of HSLA Steel
(Journal Iron Steel Research Editorial Board, Beijing, 2011)
Welded joint is a critical region of a welded structure. The operational safety of welded pressure equipment mostly depends on the behaviour of loaded weldments. Safety of welded structure is dependent on the properties ...
Development directions of packaging made from polymer materials / Pravci razvoja ambalaže od polimernih materijala
(Association of Chemical Engineers of Serbia, 2011)
World packaging market achieves turnover of about $620 billion per year with one third of this amount being associated with packaging made from polymer materials. It is expected that this kind of packaging consumption will ...
The production of lactic acid on liquid distillery stillage by Lactobacillus rhamnosus ATCC 7469 / Proizvodnja mlečne kiseline na tečnoj destilerijskoj džibri pomoću Lactobacillus rhamnosus ATCC 7469
(Univerzitet u Nišu - Tehnološki fakultet, Leskovac, 2011)
The production of lactic acid on a liquid distillery stillage remaining after the bioethanol production on a mixture of waste bread and waste water from the production of wheat gluten was studied in this work. The lactic ...
Study of factors affecting Ni2+ immobilization efficiency by temperature activated red mud
(Elsevier Science Sa, Lausanne, 2011)
The waste red mud, remaining in remarkable quantities after the digestion of bauxite ores following the Bayer process, contains number of voluble minerals with excellent sorption properties towards aqueous heavy metals. ...
