Generalized point interaction and tunneling times
(World Scientific Publ Co Pte Ltd, Singapore, 2012)
The scattering properties of four-parameter one-dimensional point interactions also define time aspect of these interactions. In this paper we investigate how different families of point interactions affect the relevant ...
Modification of PET and PA fabrics with alginate and copper oxides nanoparticles
(Composite Interfaces, 2021)
The aim of this study was to fabricate novel antimicrobial nanocomposite materials by in-situ syntheses of Cu-based nanoparticles on PET and PA fabrics. The synthesis comprised three steps: (i) modification of PET and PA ...
Formation of nano-plate silver particles in the presence of polyampholyte copolymer
(Elsevier Science Bv, Amsterdam, 2012)
Poly(2-(dimethylamino)ethyl methacrylate-co-acrylic acid) polyampholyte copolymers were synthesized by radical polymerization of the co-monomers in different molar ratios (2-1, 1-1 and 1-2). The water solutions of the ...
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 ...
Targeting and design of industrial zone waste heat reuse for combined heat and power generation
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
The basic materials industry contributes significantly to global energy demand. The efficient utilization of energy in these industries is essential to sustainable development. In numerous emerging countries, such industrial ...
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 ...
Microwave-assisted polyol synthesis of carbon-supported platinum-based bimetallic catalysts for ethanol oxidation
(Springer, New York, 2012)
High surface area carbon-supported Pt, PtRh, and PtSn catalysts were synthesized by microwave-assisted polyol procedure and tested for ethanol oxidation in perchloric acid. The catalysts were characterized by thermogravimetric ...
Specificity of maltase to maltose in three different directions of reaction: Hydrolytic, vanillyl alcohol glucoside and vanillyl alcohol isomaltoside synthesis
(Wiley, Hoboken, 2012)
Vanillyl alcohol glucoside is very attractive molecule due to its very powerful physiological activity. In this article, a detailed kinetic study of transglucosylation of vanillyl alcohol was performed. It was demonstrated ...
Bifunctional catalytic activity of Zn1-xFexO toward the OER/ORR: seeking an optimal stoichiometry
(Royal Soc Chemistry, Cambridge, 2020)
Eco-friendly and rapid microwave processing of a precipitate was used to produce Fe-doped zinc oxide (Zn1-xFexO,x= 0, 0.05, 0.1, 0.15 and 0.20; ZnO:Fe) nanoparticles, which were tested as catalysts toward the oxygen reduction ...
