In Situ Derivatization of an Intrinsic Iron Impurity as a Surface-Confined Iron(II)tris(2,2′-bipyridine) Complex on MWCNT and Its Application to Selective Electrochemical Sensing of DNA’s Purine Bases

21-May-2015 | Pinapeddavari Mayuri; Annamalai Senthil Kumar, Langmuir, 2015

The derivatization of an intrinsic iron impurity in a carbon nanotube (CNT-*Fe, *Fe-intrinsic, and redox-active iron impurity) as a functional molecular system has been challenging to realize. There are certain limitations on the derivatization of such iron impurities such as low concentration ...

Multidetector‐ThF3 as a Novel Tool for the Investigation of Solution Properties of Amphiphilic Block Copolymers

19-May-2015 | Nyashadzashe Ngaza, Margaretha Brand, Harald Pasch, Macromolecular Chemistry and Physics, 2015

In this study, multidetector Thermal FFF (ThF3) is utilized to study amphiphilic block copolymers in different selective and nonselective solvents. Depending on the solvent quality and the polymer concentration, amphiphilic block copolymers can form aggregates or micelles; the blocks can adopt ...

Separation of cobalt(II) from manganese(II) using a polymer inclusion membrane with N‐[N,N‐di(2‐ethylhexyl)aminocarbonylmethyl]glycine (D2EHAG) as the extractant/carrier

19-May-2015 | Yuzo Baba, Fukiko Kubota, Masahiro Goto, Robert W. Cattrall, Spas D. Kolev, Journal of Chemical Technology & Biotechnology, 2015

Abstract BACKGROUND The hydrometallurgical separation of Co(II) from Mn(II) poses a difficult problem because of their similar chemical and physical properties. We have attempted to develop a membrane separation method for Co(II) in the presence of Mn(II) which overcomes the potential ...

Phase Equilibrium in the Aqueous Ternary System KH2PO4+ KCl +H2O at (288.15 and 303.15) K

19-May-2015 | Jun Long; Jian-hua Tang; Yu-kun You; Lian-mei Guo; Ke Chen, Journal of Chemical & Engineering Data, 2015

In this study, the solubility and density of a ternary system (KH2PO4 + KCl + H2O) at (288.15 and 303.15) K were determined, using isothermal solution saturation and wet residues. The equilibrium solids were detected by the Schreinemaker’s method of wet residues and verified by X-ray diffraction ...

Development and validation of a generic stability‐indicating MEEKC method for five fluoroquinolone antibiotics

12-May-2015 | Eliangiringa Kaale, Ludwig Höllein, Ulrike Holzgrabe, ELECTROPHORESIS, 2015

In this paper, a reliable stability‐indicating generic MEEKC method for the analysis of five commonly used fluoroquinolones (FQs) has been developed and optimised by a central composite circumscribed experimental design. The separation was carried out using a fused silica capillary (60.2 cm ...

Tio2‐ or tio2/fe3o4‐containing PVA‐based microgels for controlled photocatalytic degradation of methyl orange

09-May-2015 | Congming Xiao, Yanhong Fang, Guoxiang Zhang, Polymer Composites, 2015

An inverse emulsion radical reaction was adopted to prepare poly(vinyl alcohol) (PVA)‐based microgels that contained titanium oxide (TiO2) or TiO2/Fe3O4, and the obtained microgels were applied to catalyze the degradation of methyl orange. First, well‐defined PVA was used to synthesize a ...
