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 ...
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 ...
Copper nanoparticles with high antimicrobial activity
(Elsevier Science Bv, Amsterdam, 2014)
Copper (Cu) hydrosol containing small nanoparticles (NPs) (similar to 5 nm) with narrow size distribution were used to investigate antimicrobial activity toward representative microorganisms of public concern (Escherichia ...
Volumetric and viscometric behavior of the binary systems ethyl lactate+1,2-propanediol,+1,3-propanediol, plus tetrahydrofuran and plus tetraethylene glycol dimethyl ether. New UNIFAC-VISCO and ASOG-VISCO parameters determination
(Elsevier Science Bv, Amsterdam, 2014)
Densities, refractive indices and viscosities of four binary systems consisting of ethyl lactate with 1,2-propanediol or 1,3-propanediol or tetrahydrofuran (THF) or tetraethylene glycol dimethyl ether (TEGDME) were measured ...
Hydrodynamic modeling of downward gas-solid flow. Part II: Co-current flow
(Elsevier, Amsterdam, 2014)
The one-dimensional model of accelerating turbulent downward co-current gas-solid flow of coarse particles was formulated and experimentally verified by measuring the pressure distribution along the transport tube. The ...
Influence of size scale and morphology on antibacterial properties of ZnO powders hydrothemally synthesized using different surface stabilizing agents
(Elsevier Science Bv, Amsterdam, 2013)
Metal oxide nanoparticles represent a new class of important materials that are increasingly being developed for use in research and health-related applications. Although the antibacterial activity and efficiency of bulk ...
Phylogenetic Analysis of Dysbiosis in Ulcerative Colitis During Remission
(Lippincott Williams & Wilkins, Philadelphia, 2013)
Background: Presence of intestinal microbes is a prerequisite for the development of ulcerative colitis (UC), although deviation of the normal intestinal microbiota composition, dysbiosis, is presumably implicated in the ...
"Green Meets Green" - Sustainable solutions of imidazolium and phosphonium ionic liquids with poly(ethylene glycol): Solubility and phase behavior
(Elsevier Science Bv, Amsterdam, 2013)
Liquid-liquid and solid-liquid phase behaviors of the binary solutions of imidazolium [C(2)mim](+) or trihexyltetradecyl phosphonium [P-6,P-6,P-6,P-14](+) ionic liquids having triflate [OTf](-), bistriflamide [NTf2](-) or ...
