Removal of model cationic dye by adsorption onto poly(methacrylic acid)/zeolite hydrogel composites: Kinetics, equilibrium study and image analysis
(Elsevier, Amsterdam, 2014)
Composites based on poly(methacrylic acid) (PMAA) and two types of zeolite, hydrophilic zeolite A and hydrophobic zeolite ZSM-5, were synthesized. The obtained hydrogel composites that combine well the strong interaction ...
Comparative life cycle assessment of Ni-based catalyst synthesis processes
(Elsevier Sci Ltd, Oxford, 2017)
Ni-based catalysts supported on ceramics are particularly suitable for industrial applications, for instance reforming of hydrocarbons to produce synthesis gas or hydrogen and production of carbon nanofibers. Conventional ...
PVA Cryogel as model hydrogel for iontophoretic transdermal drug delivery investigations. Comparison with PAA/PVA and PAA/PVP interpenetrating networks
(Elsevier, Amsterdam, 2019)
The use of polyvinyl alcohol (PVA) cryogel as a model hydrogel for iontophoretic transdermal investigations is proposed. Due to the excellent combination of its properties, it could be used for evaluating iontophoretic ...
Bactericidal activity of Cu-, Zn-, and Ag-containing zeolites toward Escherichia coli isolates
(Springer Heidelberg, Heidelberg, 2017)
Two types of zeolites-natural clinoptilolite (NZ) and synthetic zeolite A (A)-were enriched with approx. 0.25 mmol of Cu(II), Zn(II), or Ag(I) ions, and the obtained materials (M-Z) were tested against three different ...
Antimicrobial and Photocatalytic Abilities of Ag2CO3 Nano-Rods
(Wiley-VCH Verlag Gmbh, Weinheim, 2017)
The rod-like Ag2CO3 particles (2-4 3 0.3-0.6 mm, length 3 diameter) were synthesized in water by the precipitation reaction between AgNO3 and NaHCO3 in the presence of polyvinylpyrrolidone. The X-ray diffraction analysis ...
Impregnation of corona modified polypropylene non-woven material with thymol in supercritical carbon dioxide for antimicrobial application
(Elsevier Science Bv, Amsterdam, 2015)
This study discusses the possibility of impregnation of polypropylene (PP) and corona modified PP non-woven material with thymol in supercritical solvent in order to fabricate eco-friendly antimicrobial textile material. ...
Flowering of 'Oblacinska' sour cherry clones in Serbia
(Int Soc Horticultural Science, Leuven 1, 2017)
Flowering is one of the most important factors in plant fertility. Fruit set in fruits is directly influenced by the beginning, sequence, flow, duration and abundance of flowering. The objective of this study was to evaluate ...
