The removal of Zn2+, Pb2+, and As(V) ions by lime activated fly ash and valorization of the exhausted adsorbent
(Pergamon-Elsevier Science Ltd, Oxford, 2018)
This study focuses on the use of raw fly ash (FA) and modified fly ash - activated by lime (MFA), as effective and low-cost adsorbents for the removal of heavy metals (Zn2+, Pb2+ and As(V)), followed by the revalorization ...
Selection of the best pollinizer of ‘Celina’ pear
(Int Soc Horticultural Science, Leuven 1, 2018)
The Norwegian newly bred pear cultivar, Celina/QTee®, which was launched in 2010, has been released from the Norwegian breeding program that was initiated in 1983. It was derived from the combination ‘Colorée de Juillet’ ...
Mechanism and degradation kinetics of zinc complex containing isophthalato and 2,2 '-dipyridylamine ligands under different atmospheres
(Elsevier Masson SAS, 2018)
The design of mixed-ligand complexes are of increasing interest from fundamental as well as technological and curative aspects. Having that in mind, we studied zinc complex containing 2,2'-dipyridylamine (dipya) and dianion ...
Supercritical CO2 impregnation of PLA/PCL films with natural substances for bacterial growth control in food packaging
(Elsevier Science Bv, Amsterdam, 2018)
Biodegradable polymers with antibacterial properties are highly desirable materials for active food packaging applications. Thymol, a dietary monoterpene phenol with a strong antibacterial activity is abundant in plants ...
Pectin-based nanocomposite aerogels for potential insulated food packaging application
(Elsevier Sci Ltd, Oxford, 2018)
Environmental-friendly pectin-TiO2 nanocomposite aerogels were prepared via sol-gel process and subsequent drying under supercritical conditions. The first step includes dissolution of pectin in water, addition of proper ...
Pyro-Refining of Mechanically Treated Waste Printed Circuit Boards in a DC Arc-Furnace
(Springer, New York, 2018)

Solvatochromism and quantum mechanical investigation of disazo pyridone dye
(Wiley, Hoboken, 2018)
Disazo pyridone dye, 4-methyl-2,6-dioxo-5-(2-(4-(phenyldiazenyl)phenyl)hydrazono)-1,2,5,6-tetrahydropyridine-3-carbonitrile, is synthesised and thoroughly characterised by a combination of experimental and computational ...
Composite materials from fully bio-based thermosetting resins and recycled waste poly(ethylene terephthalate)
(Elsevier Sci Ltd, Oxford, 2018)
During the last two decades, interest in bio-based polymers, especially in bio-based composite materials, has grown as a result of environmental concerns. In this paper new composites obtained from fully bio-based unsaturated ...
Comprehensive electrochemical study on corrosion performance of graphene coatings deposited by chemical vapour deposition at atmospheric pressure on platinum-coated molybdenum foil
(Pergamon-Elsevier Science Ltd, Oxford, 2018)
In this work, we present the results of electrochemical, Raman, FE-SEM/EDS, and XPS studies of graphene coatings deposited by chemical vapour deposition at atmospheric pressure on Mo foil and Pt-coated Mo foil as catalysts. ...
In situ electrochemical synthesis of silver-doped poly(vinyl alcohol)/graphene composite hydrogels and their physico-chemical and thermal properties
(Elsevier Sci Ltd, Oxford, 2018)
This paper presents silver/poly(vinyl alcohol) (Ag/PVA) and silver/poly(vinyl alcohol)/graphene (Ag/PVA/Gr) composites prepared by the immobilization of silver nanoparticles (AgNPs) in PVA and PVA/Gr hydrogel discs previously ...
