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 ...
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 ...
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 ...
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 ...
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 ...
Short-circuit oxygen diffusion in thermally grown silica layer
(World Scientific Publ Co Pte Ltd, Singapore, 2010)
Amorphous polymer-derived Si-C-N ceramics can be doped with different elements (Al, B etc.) through various pre-ceramic polymer routes. Thus, controlling of the high temperature oxidation resistance can be achieved on an ...
Influence of picosecond laser pulses on the microstructure of austenitic materials
(Springer, New York, 2011)
We investigate samples of austenitic materials - stainless steel and iron-based superalloy - which are widely used at high temperatures and pressures. The samples were exposed to Nd(3+):YAG laser pulses with a wavelength ...
Field performance of micropropagated rubus species
(Acta Scientiarum Polonorum, Hortorum Cultus, 2016)
The objective of this study was to test yield and fruit quality of the red raspberry 'Meeker' and the blackberry 'Cacanska Bestrna' propagated using the standard method (ST) and in vitro, by tissue culture (TC). The monitored ...
Multipurpose nonwoven viscose/polypropylene fabrics: Effect of fabric characteristics on sorption and dielectric properties
(Wiley, Hoboken, 2018)
In this work, sorption and dielectric properties of viscose/polypropylene multipurpose nonwoven fabrics were examined. The analysis of sorption behavior showed that the changes of the water absorptive capacity, the height ...
Silver incorporation on viscose and cotton fibers after air, nitrogen and oxygen DBD plasma pretreatment
(Springer, Dordrecht, 2013)
Dielectric barrier discharge (DBD) pretreatments in air, nitrogen and oxygen plasma of viscose and cotton fabrics with subsequent immobilization of silver were studied. Surface activation of treated fibers was evaluated ...
