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 ...
Optimization of modifier deposition on the alumina surface to enhance mechanical properties and cavitation resistance
(Springer, New York, 2020)
Composites based on poly(methyl methacrylate), dimethyl itaconate matrix and alumina particles were prepared. Ferrous oxide-doped alumina particles (Al2O3Fe) and commercial alumina nanoparticles (Al(2)O(3)n) modified with ...
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 ...
Tio2/zro2 thin films synthesized by pld in low pressure n-, c- and/or o-containing gases: structural, optical and photocatalytic properties
(Inst Materials Physics, Bucharest, 2012)
Doped TiO2/ZrO2 films were obtained by Pulsed Laser Deposition method under different synthesis conditions. The onset of absorption spectra was red shifted for the films obtained in N-2 containing gas mixtures, while a ...
Modification of PET and PA fabrics with alginate and copper oxides nanoparticles
(Composite Interfaces, 2021)
The aim of this study was to fabricate novel antimicrobial nanocomposite materials by in-situ syntheses of Cu-based nanoparticles on PET and PA fabrics. The synthesis comprised three steps: (i) modification of PET and PA ...
Evaluation of the impact of critical quality attributes and critical process parameters on quality and stability of parenteral nutrition nanoemulsions
(Elsevier, Amsterdam, 2017)
The aim of this study was to develop, characterize and evaluate concentrated nanoemulsions (20%) for parenteral nutrition. Those systems were developed by the high-pressure homogenization method. Optimal conditions for the ...
Pollen tube growth and fruit set in quince (Cydonia oblonga Mill.)
(Spanish Natl Inst Agricultural & Food Research & Technolo, Madrid, 2020)
Aim of study: To determine the self-compatibility level of eight quince cultivars. Area of study: The region of Belgrade (Central Serbia). Material and methods: Pollen tube growth in vivo and fruit set in two pollination ...
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 ...
Challenging the difference between white and brown Agaricus bisporus mushrooms: Science behind consumers choice
(Emerald Group Publishing Ltd, Bingley, 2018)
Purpose The purpose of this paper is to examine compositional differences between brown and white varieties of Agaricus bisporus during shelf life and to determine if the growing demand for the brown variety is scientifically ...
Equilibrium, kinetic and thermodynamic studies on removal of Cd(II), Pb(II) and As(V) from wastewater using carp (cyprinus carpio) scales
(Inst Materials Physics, Bucharest, 2013)
Unmodified farming carp (cyprinus carpio) scales were used as a biosorbent for the removal of Cd(II), Pb(II) and As(V) ions from aqueous solutions. The adsorption studies were conducted as a function of pH, contact time ...
