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 ...
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 ...
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 ...
Efficient As(V) removal by alpha-FeOOH and alpha-FeOOH/alpha-MnO2 embedded PEG-6-arm functionalized multiwall carbon nanotubes
(Inst Chemical Engineers, Rugby, 2017)
A novel adsorbents, 6-arm amino polyethylene glycol functionalized multiwall carbon nanotubes (PEG/MWCNT) loaded with alpha-FeOOH (Fe/PEG/MWCNT), and hybrid alpha-FeOOH/alpha-MnO2 nano-deposit (Fe-Mn/PEG/MWCNT) were used ...
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 ...
Structural and biological evaluation of lignin addition to simple and silver-doped hydroxyapatite thin films synthesized by matrix-assisted pulsed laser evaporation
(Springer, Dordrecht, 2015)
We report on thin film deposition by matrix-assisted pulsed laser evaporation of simple hydroxyapatite (HA) or silver (Ag) doped HA combined with the natural biopolymer organosolv lignin (Lig) (Ag:HA-Lig). Solid cryogenic ...
Evaluation of poly(hydroxyethyl acrylate/itaconic acid) hydrogels for controlled delivery of transition metal complexes with Oxaprozin as potential antiproliferative agents
(Springer, New York, 2015)
A series of dual-sensitive poly(2-hydroxyethyl acrylate/itaconic acid) (P(HEA/IA)) hydrogels were synthesized and evaluated as drug delivery systems for potential antiproliferative agents. Investigated hydrophobic compounds, ...
Silicon nanostructuring by Ag ions implantation through nanosphere lithography mask
(Elsevier Science Bv, Amsterdam, 2019)
Nanosphere lithography is an effective technique for high throughput fabrication of well-ordered patterns on large areas. This study reports on nanostructuring of silicon samples by means of Ag ions implantation through ...
Oxaprozin/poly(2-hydroxyethyl acrylate/itaconic acid) hydrogels: morphological, thermal, swelling, drug release and antibacterial properties
(Springer, New York, 2015)
In this study, a series of novel stimuli-sensitive hydrogels based on 2-hydroxyethyl acrylate and itaconic acid monomers were designed for the controlled release of hydrophobic drug, Oxaprozin. All samples were synthesized ...
