Phosphorus-nitrogen compounds. 14. Synthesis, stereogenism, and structural investigations of novel N/O spirocyclic phosphazene derivatives
(Amer Chemical Soc, 2007)
The reactions of hexachlorocyclotriphosphazatriene, N3P3Cl6, with N/O donor-type N-alkyl-o-hydroxybenzyl- and o-hydroxynaphthylamines result in novel mono-(3a, 4a and 4b), di- (5a and 5b), and tri- (3b, 6a, and 6b) spirocyclic ...
Fabrication of a kappa-carrageenan-based electroactive cytochrome c multilayer thin film by an electrostatic layer-by-layer assembly
(Elsevier Science Sa, 2019)
The aim of this study was to demonstrate the usability of kappa-carrageenan in the accumulation of a layer by layer protein film on a gold electrode. It is known that in terms of bioelectronics there are significant ...
Removal of heavy mercury(II), cadmium(II) and zinc(II) metal ions by live and heat inactivated Lentinus edodes pellets
(Elsevier Science Sa, 2008)
The live and heat inactivated forms of Lentinus edodes pellets were used for the biosorption of Hg2+, Cd2+ and Zn2+ ions. The maximum adsorption of metal ions on the live and heat inactivated pellets of fungus was observed ...
Microwave-assisted synthesis of alginate-g-polyvinylpyrrolidone copolymer and its application in controlled drug release
(Springer, 2014)
The aim of this study is to synthesize graft copolymer (NaAlg-g-PVP) in microwave oven and prepare pH-responsive beads with high entrapment efficiency. For this purpose, PVP was grafted onto sodium alginate using microwave ...
Determination of iron and nickel by flame atomic absorption spectrophotometry after preconcentration on Saccharomyces cerevisiae immobilized sepiolite
(Elsevier Science Bv, 1998)
Iron and nickel have been preconcentrated on Saccharomyces cerevisiae immobilized sepiolite and determined by flame atomic absorption spectrophotometry (FAAS). Preconcentration studies were conducted by the column method. ...
Adsorption of copper(II), cobalt(II), and iron(III) ions from aqueous solutions on poly(ethylene terephthalate) fibers
(John Wiley & Sons Inc, 1998)
The adsorption behavior of poly(ethylene terephthalate) (PET) fibers towards copper(II), cobalt(II), and iron(III) ions in aqueous solutions was studied by a batch equilibriation technique. Influence of treatment time, ...
Statistical Classification of Cigarettes Using High Pressure Liquid Chromatograms of Cigarette Filter Tar as Fingerprint
(Asian Journal Of Chemistry, 2013)
In this work, we have showed that a liquid chromatogram can be used as finger print to characterize and classify cigarettes. A liquid chromatographic (high pressure liquid chromatography) procedure was first developed to ...
Immobilization of glucose isomerase in surface-modified alginate gel beads
(Wiley, 2008)
In this study, glucose isomerase enzyme was entrapped into modified and nonmodified calcium alginate gel beads. Various characteristics of free and immobilized enzymes such as the optimum pH, temperature and dependence of ...
Mn3O4/p(DCPD)HIPE nanocomposites as an efficient catalyst for oxidative degradation of phenol
(SPRINGER, 2020)
The increase in the amount of wastewater containing organic pollutants in various industrial processes creates serious problems for the environment. Sulfate radical-based advanced oxidation process (AOP) is an effective ...
Application of FAM ligands in the metal-promoted catalytic enantioselective synthesis of organic compounds
(Scientific Technical Research Council Turkey-Tubitak, 2009)
Novel ferrocenyl substituted aziridinyl methanol (FAM) ligands were synthesized and successfully used in metal-promoted catalytic enantioselective azomethine ylide cycloadditions, diethylzinc additions to enones, alkynylzinc ...
