Antioxidants from lamiaceae herbs
(Food Quality: Control, Analysis and Consumer Concerns, 2011)
One of the important trends in the food industry today is the demand for natural antioxidants from plant material. Synthetic antioxidants such as butylated hydroxytoluene (BHT), and butylated hydroxyanisole (BHA) now being ...
Thermomechanical Properties and Cavitation Resistance of a High-Alumina Low-Cement Castable
(Wiley-Blackwell, Malden, 2011)
The purpose of this study was to investigate the mechanical properties and level of cavitation damage to alumina-based low-cement castable. The effects of temperature treatment on some of the mechanical properties (strength, ...
Synthesis, structure, and solvatochromic properties of pharmacologically active 5-substituted 5-phenylhydantoins
(Springer Wien, Wien, 2011)
A series of 5-substituted 5-phenylhydantoins was synthesized and their UV absorption spectra were recorded in the region 200-400 nm in selected solvents of different polarity. The effects of solvent dipolarity/polarizability ...
Durability of sulfur concrete in various aggressive environments
(Elsevier Sci Ltd, Oxford, 2011)
Durability of sulfur concrete with different fillers, as well as Portland cement concrete, was tested in the solutions of HCl, H(2)SO(4), and NaCl. Regarding mass changes, in the solutions of HCl and H(2)SO(4) sulfur ...
Synthesis and characterization of silver/poly(N-vinyl-2-pyrrolidone) hydrogel nanocomposite obtained by in situ radiolytic method
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
This work describes radiolytic synthesis of silver nanoparticles (Ag NPs) within the poly(N-vinyl-2-pyrrolidone) (PVP) hydrogel. The hydrogel matrix was obtained by gamma irradiation-induced cross-linking, while the in ...
Reduction of ultra-fine tungsten powder with tungsten (vi) oxide in a vertical tube reactor
(Institute of Metals and Technology, 2011)
The reduction of WO(3) with hydrogen in a vertical tube reactor is a new approach to the reduction of tungsten oxide compared to conventional procedures in a stationary layer. The advantage of this method is the intensive ...
Surface Characterization of Iron-Modified Sepiolite by Inverse Gas Chromatography
(Amer Chemical Soc, Washington, 2011)
Inverse gas chromatography at infinite and finite surface coverages was applied to evaluate the surface properties of an iron-modified sepiolite sorbent, Fe-sepiolite. The adsorptions of different nonpolar and polar probes ...
Strain hardening of austenite in Fe-Cr-C-V alloys under repeated impact
(Elsevier Science Sa, Lausanne, 2011)
Structural changes were analyzed in Fe-Cr-C-V alloy balls with high chromium and different vanadium content, after repeated impact load testing. The results indicate that plastic deformation and strain hardening occur in ...
Network Theory of Living Cell Clusters and Rheological Applications at Nano-Level
(Polish Acad Sciences Inst Physics, Warsaw, 2011)
The system of living cells closed in a polymer matrix and self-organized into clusters is considered, extending free volume concept developed for complex system interactions quantification in statistical mechanics of jammed ...
Determination of fatigue crack growth parameters in welded joint of HSLA steel / Određivanje parametara zamornog rasta prsline kod zavarenih spojeva od HSLA čelika
(Society for Structural Integrity and Life, Institute for Material Testing, 2011)
The structural integrity and operational safety of welded pressure vessels primarily depends on the behaviour of weldments. In spite of all efforts in material production and improvements in welding techniques, including ...
