Solvatochromic and quantum chemical investigations of newly synthesized succinimides: substituent effect on intramolecular charge transfer
(Springer Wien, Wien, 2013)
Two series of 1-aryl-3-phenyl- and 1-aryl-3,3-diphenylpyrrolidine-2,5-diones were synthesized and their solvatochromic properties were studied in a set of 15 solvents of different polarity. The effect of specific and ...
Removal of heavy metals from aqueous solution using natural and fe(iii) oxyhydroxide clinoptilolite
(Clay Minerals Soc, Chantilly, 2013)
The increasing levels of industrial wastewater released to the environment present a serious threat to human health, living resources, and ecological systems. Fe-modified zeolites were developed and tested for removal of ...
The use of image analysis for determination of surface deterioration level of improved alumina based materials subjected to cavitation
(International Institute for the Science of Sintering, Beograd, 2013)
Alumina based specimens having different content of alumina based fibers were investigated for possible application as cavitation resistant material. Cavitation damages of the alumina based specimens were tested by the ...
Mechanical and anti-stabbing properties of modified thermoplastic polymers impregnated multiaxial p-aramid fabrics
(Wiley, Hoboken, 2013)
New forms of hybrid multiaxial nanocomposites with enhanced mechanical and stab resisting properties are presented. This study is motivated by the lack of knowledge in the study of the multiaxial fabric nanocomposites with ...
Sensitive HPLC Method for the Determination of Usnic Acid in Tablets
(Elsevier Science Bv, Amsterdam, 2013)
The Effects of Functionalization on the Thermal and Tribo-Mechanical Behaviors of Neat and Grafted Polyethylene Nanocomposites
(Wiley, Hoboken, 2013)
This article presents research on the influence of a coupling agent -methacryloxypropyltrimethoxysilane (MEMO) and cross-linking agent dicumyl peroxide (DCP) on thermal and nanomechanical properties of neat and waste ...
Photocatalytic Degradation of Dye CI Direct Blue 78 Using TiO2 Nanoparticles Immobilized on Recycled Wool-Based Nonwoven Material
(Wiley, Hoboken, 2013)
This paper discusses the possibility of immobilization of TiO2 nanoparticles onto recycled wool-based nonwoven material, which can be utilized for removal of dyes from wastewater. The photocatalytic activity of TiO2 ...
Equilibrium, kinetic and thermodynamic studies on removal of Cd(II), Pb(II) and As(V) from wastewater using carp (cyprinus carpio) scales
(Inst Materials Physics, Bucharest, 2013)
Unmodified farming carp (cyprinus carpio) scales were used as a biosorbent for the removal of Cd(II), Pb(II) and As(V) ions from aqueous solutions. The adsorption studies were conducted as a function of pH, contact time ...
Microarray analysis reveals marked intestinal microbiota aberrancy in infants having eczema compared to healthy children in at-risk for atopic disease
(Biomed Central Ltd, London, 2013)
Background: Deviations in composition and diversity of intestinal microbiota in infancy have been associated with both the development and recurrence of atopic eczema. Thus, we decided to use a deep and global microarray-based ...
Corrosion behaviour of thixoformed and heat-treated ZA27 alloys in NaCl solution
(Elsevier Science Bv, Amsterdam, 2013)
The influence of corrosion on the microstructure of thixoformed and heat-treated ZA27 alloys was investigated. The microstructure of ZA27 alloy was affected by heat treatment. The process of electrochemical corrosion occurs ...
