Re-refining of waste mineral insulating oil by extraction with N-methyl-2-pyrrolidone
(Elsevier Science Bv, Amsterdam, 2006)
Extraction with N-methyl-2-pyrrolidone (NMP) via the three-stage mixer-settler operation was studied as possible process for re-refining of waste mineral insulating oil. The following extraction process parameters were ...
Semi-Interpenetrating Networks Based on Poly(N-isopropyl acrylamide) and Poly(N-vinylpyrrolidone)
(Wiley, Hoboken, 2009)
Three series of novel semi-interpenetrating polymer networks, based on crosslinked poly(N-isopropylacrylamide), PNIPA, and different amounts of the linear poly(N-vinylpyrrolidone), PVP, were synthesized to improve the ...

The title of the article should read as follows: Solubility in K+–Na+–Mg (2+)– SO (4) (2-) Aqueous Solution at T = 298.15 K.
Leaching properties of secondary lead slag stabilized/solidified with cement and selected additives
(Environment Protection Engineering, 2013)
Sodium lead slag, generated during secondary lead production, is characterized as hazardous waste. The aim of the study was to investigate leaching mechanism and behaviour of lead and arsenic from sodium lead slag previously ...
Biodegradation of cellulose fibers functionalized with CuO/Cu2O nanoparticles in combination with polycarboxylic acids
(Cellulose, 2022)
Sustainable biodegradation of cellulose fibers is critical for composting after the end of a product's life. In this study, we aimed at investigating the effect of in situ synthesized CuO/Cu2O nanoparticles (NPs) with ...
Diffusion of polyphenols from alginate, alginate/chitosan, and alginate/inulin particles
(Wiley, Hoboken, 2019)
Thymus serpyllum L (thyme) aqueous extract was encapsulated within three different types of particles. Thus, electrostatic extrusion was applied to obtain alginate, alginate/chitosan, and alginate/inulin particles with ...
Effect of synthesis parameters on polymethacrylic acid xerogel structures and equilibrium swelling
(Maik Nauka/Interperiodica/Springer, New York, 2009)
Hydrogels based on crosslinked polymethacrylic acid were synthesized via free-radical polymerization in aqueous solution, using N,N'-methylene bisacrylamide as a crosslinking agent and 2,2'-azobis-[2-(2-imidazolin-2-yl)propane] ...
Characterization of sepiolite by inverse gas chromatography at infinite and finite surface coverage
(Elsevier Science Bv, Amsterdam, 2009)
The adsorption properties of sepiolite from Andrici, Serbia, were studied by inverse gas chromatography at zero and finite surface coverage between 483 and 513 K. The thermodynamic parameters (free energy, enthalpy, entropy) ...
Design and characterization of self-assembled fish sarcoplasmic protein-alginate nanocomplexes
(Elsevier, Amsterdam, 2015)
Macrostructures based on natural polymers are subject to large attention, as the application range is wide within the food and pharmaceutical industries. In this study we present nanocomplexes (NCXs) made from electrostatic ...
Antibacterial activity of heavy metal-loaded natural zeolite
(Elsevier Science Bv, Amsterdam, 2012)
The antibacterial activity of natural zeolitized tuffs containing 2.60 wt.% Cu2+, 1.47 Zn2+ or 0.52 Ni2+ were tested. Antibacterial activities of the zeolites against Escherichia coli and Staphylococcus aureus were tested ...
