Properties and drug release profile of poly(N-isopropylacrylamide) microgels functionalized with maleic anhydride and alginate
(Springer, New York, 2013)
This study highlights the advantages of functionalized poly(N-isopropylacrylamide) (PNIPAAm) microgels over pure PNIPAAm microgels in terms of polymer network properties and drug release profiles. PNIPAAm network was ...
Influence of surface modified TiO2 nanoparticles by gallates on the properties of PMMA/TiO2 nanocomposites
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
Nanocomposites based on poly(methyl methacrylate) (PMMA) and TiO2 nanoparticles were synthesized by in situ radical polymerization of MMA in solution. The surface of TiO2 nanoparticles was modified with four gallic acid ...
Evaluation of periodic processes with two modulated inputs based on nonlinear frequency response analysis. Case study: CSTR with modulation of the inlet concentration and flow-rate
(Pergamon-Elsevier Science Ltd, Oxford, 2013)
In our previous work, a new, fast and easy, nonlinear frequency response method for analysing potential improvements of reactor performance by forced periodic operation was presented. This method, which is based on Volterra ...
Mechanical and thermal properties of UV cured mixtures of linear and hyperbranched urethane acrylates
(Elsevier Science Sa, Lausanne, 2012)
The properties of urethane acrylate resin mixtures based on the linear and hyperbranched aliphatic polyesters were examined. Linear polyester was synthesized from neopentil glycol and adipic acid. Hyperbranched polyester ...
Synthesis of fluorine substituted hydroxyapatite nanopowders and application of the central composite design for determination of its antimicrobial effects
(Elsevier Science Bv, Amsterdam, 2014)
Synthetic biomaterials based on fluorine substituted hydroxyapatite are potentially attractive for orthopedic and dental implant applications. The new synthesis of fluorine substituted hydroxyapatite samples were done by ...
Mg-modified zeolite as a carrier for Lactobacillus rhamnosus in L(+) lactic acid production on distillery wastewater
(Elsevier Science Bv, Amsterdam, 2016)
Biorefinery concept in lactic acid (LA) fermentation based on parallel production of LA and biomass enriched feed on a waste substrate was investigated. In this study, nitrogen opulent liquid stillage was used as a media ...
Influence of TiO2 nanoparticles on formation mechanism of PANI/TiO2 nanocomposite coating on PET fabric and its structural and electrical properties
(Elsevier Science Sa, Lausanne, 2015)
Polyester fibers gained significant share from all other man-made fibers, but despite numerous advantages a characteristic static electricity generation is still seeking innovative solutions. In order to improve electrical ...
Sintering, crystallization and foaming of La2O3 center dot SrO center dot 5B(2)O(3) glass powders - effect of the holding temperature and the heating rate
(Elsevier Science Bv, Amsterdam, 2018)
The peculiarities of sinter-crystallization of La2O3 center dot SrO center dot 5B(2)O(3) fine glass powder (below 1 mu m) are investigated and discussed. The sintering was studied by contactless optical dilatometry and ...
Bimetallic alginate nanocomposites: New antimicrobial biomaterials for biomedical application
(Elsevier Science Bv, Amsterdam, 2018)
Two bimetallic (Zn/Cu) alginate based nanocomposites, impregnated with carbonate or phosphate mineral phase, were prepared by a facile procedure. Mineralized samples exhibited different morphologies and properties when ...
Influence of the Thermomechanical Treatment on the Intergranular Corrosion Susceptibility of Zn-Modified Al-5.1 Wt Pct Mg-0.7 Wt Pct Mn Alloy Sheet
(Springer, New York, 2014)
In this study, the effect of thermomechanical treatment on intergranular corrosion (IGC) susceptibility of the Zn-modified Al-5.1 wt pct Mg-0.7 wt pct Mn alloy plates was investigated. The specimens underwent varied amounts ...
