The analysis of simultaneous clove/oregano and clove/thyme supercritical extraction
(Elsevier, Amsterdam, 2011)
The goal of present work was to investigate and explain kinetics and mass transfer phenomena occurring during the SFE from the mixture of two plants with different initial composition. The extractions from pure clove, ...
Bactericidal Efficiency of Silver Nanoparticles Deposited onto Radio Frequency Plasma Pretreated Polyester Fabrics
(Amer Chemical Soc, Washington, 2010)
The potential application of low-temperature radio frequency (RF) plasma for fiber surface activation in order to enhance the binding efficiency of colloidal silver nanoparticles onto the polyester fabrics and improve the ...
Microencapsulation of Flavors in Carnauba Wax
(MDPI, Basel, 2010)
The subject of this study is the development of flavor wax formulations aimed for food and feed products. The melt dispersion technique was applied for the encapsulation of ethyl vanillin in wax microcapsules. The surface ...
Deciduous tree leaves in trace elements biomonitoring: A contribution to methodology
(Elsevier Science Bv, Amsterdam, 2011)
Air quality biomonitoring using plant leaves has been widely applied to assess the effects of atmospheric pollution. Although practiced for many years, it has not given completely satisfactory data, due to different and ...
Nonlinear frequency response analysis: a recent review and perspectives
(Current Opinion in Electrochemistry, 2021)
The nonlinear frequency response analysis (NFRA) can be seen as an extension of electrochemical impedance spectroscopy. NFRA gives a full and detailed representation of the system response and can establish a connection ...
Isolation and Biological Evaluation of Jatrophane Diterpenoids from Euphorbia dendroides
(Amer Chemical Soc, Washington, 2011)
From the Montenegrin spurge Euphorbia dendroides, seven new diterpenoids [jatrophanes (1-6) and a tigliane (7)] were isolated and their structures elucidated by spectroscopic techniques. The biological activity of the new ...
Electrochemical synthesis and characterization of polyaniline thin film and polyaniline powder
(Elsevier Science Sa, Lausanne, 2011)
The polyaniline thin film electrode and powder have been synthesized on graphite electrodes from 0.5 M hydrochloric acid solution under galvanostatic conditions. The water insoluble and acetone soluble polyaniline mass ...
Synthesis of antimicrobial monophase silver-doped hydroxyapatite nanopowders for bone tissue engineering
(Elsevier, Amsterdam, 2011)
Monophase silver-doped hydroxyapatite (AgxCa10-x(PO4)(6)(OH)(2); 0.002 lt = x lt = 0.04) nanoparticles were prepared using a neutralization method and investigated with respect to potential medical applications. This ...
Corrosion stability of Zn-Co alloys deposited from baths with high and low Co content - The influence of deposition current density
(Elsevier Science Sa, Lausanne, 2010)
Electrochemically deposited Zn-Co alloys under various deposition conditions were investigated using atomic absorption spectroscopy (AAS) for determination of chemical composition, anodic linear sweep voltammetry (ALSV) ...
Chitosan, itaconic acid and poly(vinyl alcohol) hybrid polymer networks of high degree of swelling and good mechanical strength
(Wiley, Hoboken, 2010)
Chitosan is a biodegradable, non-toxic, biocompatible polymer convenient for use in drug delivery. In this study, hybrid polymeric networks (HPNs) based on chitosan, itaconic acid and poly(vinyl alcohol) (PVA) were prepared ...
