Adsorption kinetics of polyethersulfone membrane-supported hydrogels
(Hopkinton : Desalination Publications, 2018)
This study presents the route for preparation of the membrane-supporting materials with good mechanical behavior and adsorption properties that provide functionality and are easy to use in various environments. Polyethersulfone ...
Production of raw-starch-digesting alpha-amylase isoform from Bacillus sp under solid-state fermentation and biochemical characterization
(Springer, New York, 2014)
alpha-Amylase production by solid-state fermentation of different Bacillus sp. was studied previously on different fermentation media. However, no study has been reported on the influence of selected media on expression ...
Treatment of Waste Copper Electrolytes Using Insoluble and Soluble Anodes
(Esg, Belgrade, 2013)
The use of copper anodes with non standard content of impurities for the treatment of waste, sulphur acid solutions that came as a result of the industrial process of electrolytic copper refining was investigated. Those ...
Degradation behaviour of PCL/PEO/PCL and PCL/PEO block copolymers under controlled hydrolytic, enzymatic and composting conditions
(Elsevier Sci Ltd, Oxford, 2017)
Short-term hydrolytic and enzymatic degradation of poly(epsilon-caprolactone) (PCL), one series of triblock (PCL/PEO/PCL) and the other of diblock (PCL/PEO) copolymers, with a low content of hydrophilic PEO segments is ...
Thermal, structural and electrical properties of some bi-cu-ni alloys
(Polish Acad Sciences Committee Metallurgy, Krakow, 2014)
The Bi-Cu-Ni ternary system belongs to the group of potential Cu-Ni-based advanced lead-free solder materials for high temperature application. In this study microstructure investigation of the slow-cooled Bi-Cu-Ni samples ...
Quantification of the push-pull effect in 2-alkylidene-4-oxothiazolidines by using NMR spectral data and barriers to rotation around the C=C bond
(Royal Soc Chemistry, Cambridge, 2016)
Information about the strength of donor-acceptor interactions in push-pull alkenes is valuable, as this so-called "push-pull effect'' influences their chemical reactivity and dynamic behaviour. In this paper, we discuss ...
Mono BN-substituted analogues of naphthalene: a theoretical analysis of the effect of BN position on stability, aromaticity and frontier orbital energies
(Royal Soc Chemistry, Cambridge, 2018)
All isomeric BN isosteres of naphthalene have been studied theoretically, at the B3LYP/6-311+G(d,p) level, in order to investigate the effect of the BN position in a molecule on relative stability, aromaticity and frontier ...
Cytotoxic Effect of Wine Polyphenolic Extracts and Resveratrol Against Human Carcinoma Cells and Normal Peripheral Blood Mononuclear Cells
(Mary Ann Liebert Inc, New Rochelle, 2010)
Red and white wine polyphenols have been reported to provide substantial health benefits. In this study, the cytotoxic activity of red and white wine polyphenolic extracts and of resveratrol was evaluated against different ...
