The influence of different extraction conditions on polyphenol content, antioxidant and antimicrobial activities of wild thyme
(Journal of Applied Research on Medicinal and Aromatic Plants, 2021)
The aims of the presented study were the investigation of the effect of different ultrasound-assisted extraction conditions (particle size, solid-to-solvent ratio, ethanol concentration and time) on polyphenol and flavonoid ...
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 ...
Opportunities for intensification of Fischer-Tropsch synthesis through reduced formation of methane over cobalt catalysts in microreactors
(Royal Soc Chemistry, Cambridge, 2015)
Due to the global growth in production of synthetic fuels via the Gas-to-Liquid (GTL), Coal-To-Liquid (CTL) and Biomass-To-Liquid (BTL) processes, academic and industrial interest in Fischer-Tropsch synthesis (FTS) research ...
Differences in coating mechanism of structurally different aluminosilicates observed through the thermal analysis
(Springer, Dordrecht, 2018)
Systematic modification of three structurally different minerals (zeolite, mica, and vermiculite) was carried out with the aim of determining the modification mechanism and exposing the hydrophobic surface that can be used ...
Photocatalytic Ability of Visible-Light-Responsive TiO2 Nanoparticles
(Amer Chemical Soc, Washington, 2016)
The synthetic procedures for preparation of free-standing and attached to polymer support surface modified TiO2 nanoparticles (NPs) with absorption extended into the visible spectral region due to charge transfer complex ...

(Springer, New York, 2015)
The objective of this research was to design an efficient continuously operated membrane reactor with a separation unit for egg white protein (EWP) hydrolysis and production of hydrolysates with improved antioxidant ...
Ex-situ sensitization of ordered TiO2 nanotubes with CdS quantum dots
(Elsevier Sci Ltd, Oxford, 2015)
Ordered titania nanotubes (pore diameter approximate to 90 nm and wall thickness approximate to 10 nm) were obtained by the anodization technique and used for the ex-situ deposition of cadmium sulfide quantum dots (CdS ...
Antibacterial activity of modified natural clinoptilolite against clinical isolates of Acinetobacter baumannii
(Elsevier, Amsterdam, 2013)
The antibacterial activity of natural zeolite (NZ) containing 2.03 wt.% of Cu2+ (CuNZ), 5.07 of Ag+ (AgNZ) or 8.50 of benzalkonium ion (BCNZ) were tested against clinical isolates of Acinetobacter baumannii belonging to ...
Electrochemical determination of sildenafil citrate as standard, in tablets and spiked with human serum at gold and cystein modified gold electrode
(Elsevier Science Sa, Lausanne, 2016)
Nonmedical use of sildenafil citrate (SC) requires new methods for drug determination in human serum and in tablets. SC as standard and in Sildena (R) tablets is determined by square wave voltammetry (SWV) in 0.1 M H2SO4 ...
