Highly porous NiO/poly(DVB)HIPE nanocomposites for asphaltene removal: synthesis, kinetics, and thermodynamic studies
(Springer, 2019)
Asphaltene precipitation is one of the most important problems of the petroleum industry. Asphaltene collapses during petroleum processing and extraction from the well, blocking the pipes and causing many problems. For ...
Reversible immobilization of tyrosinase onto polyethyleneimine-grafted and Cu(II) chelated poly(HEMA-co-GMA) reactive membranes
(Elsevier, 2004)
The present study describes the preparation of poly(HEMA-co-GMA) reactive membranes that were grafted with polyethylenimine (PEI) following UV photo-polymerization. The immobilization of tyrosinase was carried out via ...
Thermal behaviour of alumina precursor obtained by the aluminium sulphate-urea reaction in boiling aqueous solution
(Elsevier Sci Ltd, 2003)
An aqueous solution containing 0.1 M Al3+ and excess urea was boiled for 4 h to obtain an alumina precursor precipitate. The precursor precipitate was separated into several portions and each portion was heated at a different ...
Determination of Cu, Zn, Fe, Ni and Cd by flame atomic absorption spectrophotometry after preconcentration by Escherichia coli immobilized on sepiolite
(Elsevier Science Bv, 2000)
A method for the determination of Cu, Zn, Fe, Ni and Cd by flame atomic absorption spectrophotometry (FAAS) after preconcentrating on a column containing Escherichia coli immobilized on sepiolite has been developed. Optimum ...
Poly[μ-aqua-diaqua(μ2-pyrazine-2,3-dicarboxylato)dilithium(I)]
(Wiley-Blackwell, 2009)
The asymmetric unit of the title compound, [Li-2(C6H2N2O4)(H2O)(3)](n), consists of two independent Li+ cations, one pyrazine-2,3-dicarboxylate dianion and three water molecules. One of the Li+ cations has a distorted ...
Poly[triaquabis-(μ(2)-3-carboxy-pyrazine-2-carboxyl-ato)dilithium(I)]
(Blackwell Publishing, 2008)
In the title compound, [Li-2(C6H3N2O4)(2)(H2O)(3)](n), the coordination number for both independent Li+ cations is five. One of the Li+ ions has a distorted trigonal-bipyramidal geometry, coordinated by one of the carboxyl ...
Controlled release of Aldicarb from carboxymethylcellulose microcapsules
(Scientific Technical Research Council Turkey, 1997)
Sodium carboxymethyl cellulose was converted into microspheres by crosslinking with aluminum chloride. Various microsheres with different amounts of crosslinker, biopolymer of various concentrations and molecular weights, ...
Sub-lethal toxicities of zinc pyrithione, copper pyrithione alone and in combination to the indicator mussel species Unio crassus Philipsson, 1788 (Bivalvia, Unionidae)
(TAYLOR & FRANCIS LTD, 2020)
Zinc pyrithione (ZnPT) and copper pyrithione (CuPT) are widely used antifouling booster biocides in the shipping industry as a replacement for the banned tributyltin (TBT). Sub-lethal effects of zinc pyrithione (ZnPT; 10 ...
Investigation of potential virulence genes and antibiotic resistance characteristics of Enterococcus faecalis isolates from human milk and colostrum samples
(Tubitak Scientific & Technical Research Council Turkey, 2014)
Enterococci may improve the typical taste and flavor of fermented foods through their proteolytic and lipolytic activities. However, some enterococcal strains are recognized as nosocomial pathogens, which have virulence ...
C-Banded Karyotype and Nucleolar Organizer Regions (NORs) of Wild Boar, Sus scrofa (Artiodactyla: Suidae) from Anatolia
(Tubitak Scientific & Technical Research Council Turkey, 2009)
The present study reports the karyotype, C-banding, and nucleolar organizer regions (NORs) of 6 Sus scrofa (Linnaeus, 1758) males from Anatolia. The karyotype of S. scrofa comprised (2n) 38 chromosomes, the number of ...
