Liquid velocity in a high-solids-loading three-phase external-loop airlift reactor
(Wiley-Blackwell, Hoboken, 2012)
BACKGROUND: Airlift reactors are of interest for many different processes, especially for three-phase systems. In this study the behavior of a high-loading three-phase external-loop airlift reactor was examined. In particular, ...
The inhibitory effect of oregano extract on the growth of Aspergillus spp. and on sterigmatocystin biosynthesis
(Elsevier, Amsterdam, 2012)
The aim of this study was to investigate the effect of oregano extract on the growth of Aspergillus species (Aspergillus niger, Aspergillus carbonarius, and Aspergillus wentii) isolated from food and biosynthesis of ...
The effect of lignin on the structure and characteristics of composite coatings electrodeposited on titanium
(Elsevier Science Sa, Lausanne, 2012)
Composite coatings based on lignin, obtained by electrophoretic deposition (EPD) on titanium, were investigated. The aim of this work was to produce hydroxyapatite/lignin (HAP/Lig) coatings on titanium and to investigate ...
Characterization and behavior of anesthetic bioactive textile complex in vitro condition
(Wiley-Blackwell, Malden, 2012)
In this study, a bioactive complex containing nonwoven textile material (polypropilene (PP)/viscose), chitosan hydrogel, and lidocaine hydrochloride, was designed. The purpose of such biomedical textile was in the treatment ...
Toward enhanced hydrogen production in a catalytic naphtha reforming process
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
Environmental regulations imposed on transport fuels, especially specifications on sulfur and nitrogen content, generally boost hydrogen requirements in refining industries. The catalytic naphtha reformer (CNR) process is ...
Structural and optical characteristics of silver/poly(N-vinyl-2-pyrrolidone) nanosystems synthesized by gamma-irradiation
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
Silver nanoparticles (AgNPs) were synthesized in situ by gamma-irradiation using poly(N-vinyl-2-pyrrolidone) (PVP) as a capping agent. The concentration, molecular weight and the structure (crosslinked and interpenetrated ...
Some practical aspects of nonlinear frequency response method for investigation of adsorption equilibrium and kinetics
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
Some practical aspects regarding application of the nonlinear frequency response (NFR) method for investigation of gas adsorption: choice of the optimal mass of the adsorbent, frequency range and input amplitude, are studied ...
Chemical Composition and Morphology of M7C3 Eutectic Carbide in High Chromium White Cast Iron Alloyed with Vanadium
(Iron Steel Inst Japan Keidanren Kaikan, Tokyo, 2012)
The chemical composition and morphology of M7C3 eutectic carbides in 19 mass% Cr-2.8 mass% C white iron with up to 4.7 mass% V additions have been studied. Eutectic colonies are mainly composed of a very fine rod-like ...
