Conformal growth of copper sulfide thin films on highly textured surface via a microreactor-assisted solution deposition

05-Mar-2015 | Paravee Vas-Umnuay; Ki-Joong Kim; Dae-Hwan Kim; Chih-hung Chang, CrystEngComm, 2015

In this work, the preparation of copper sulfide (CuxS) thin films via microreactor-assisted solution deposition (MASD), where separation of the homogeneous reaction and deposition from the molecular level heterogeneous surface reaction is demonstrated. A particle-free flux in solution was ...


Direct output of electrical signals from LSPR sensors on the basis of plasmon-induced charge separation

03-Mar-2015 | Tetsu Tatsuma; Yu Katagi; Satoshi Watanabe; Kazutaka Akiyoshi; Tokuhisa Kawawaki; Hiroyasu NISHI; Emiko Kazuma, Chemical Communication, 2015

Potentiometric and conductometric sensors based on localized surface plasmon resonance were developed. The sensors can be applied to coloured and turbid samples because light needs not pass through the sample solution.


Separation and concentration of sulfonylurea herbicides in milk by ionic‐liquid‐based foam flotation solid‐phase extraction

27-Feb-2015 | Liyuan Zhang, Bocheng Cao, Di Yao, Runzhong Yu, Changqing Yu, Hanqi Zhang, Aimin Yu, Journal of Separation Science, 2015

The ultrasound‐assisted ionic liquid foam flotation solid‐phase extraction of sulfonylurea herbicides in milk was developed and validated. The proteins and lipids were isolated from the sample matrix by adding salt and adjusting pH value. The target analytes eluted from the solid‐phase ...


Dispersive solid–liquid‐phase microextraction based on nanomagnetic preyssler heteropolyacid: A novel method for the preconcentration of nortriptyline

24-Feb-2015 | Zarrin Es'haghi, Sara Hooshmand, Journal of Separation Science, 2015

In this study, a new, simple, rapid and efficient method combined with UV visible spectrophotometry and high‐performance liquid chromatography analysis was developed for the extraction and determination of nortriptyline. The tendency of the preyssler tungsten heteropolyacid, H14[NaP5W30O110], ...


A Cationic Polyelectrolyte‐Controlled Liquid Mineral Precursor Process in the BaCO3 System

23-Feb-2015 | Jianhua Zhu, Lei Huang, Mingfang Cui, Li Ma, Fabin Cao, European Journal of Inorganic Chemistry, 2015

Abstract Biomimetic BaCO3 materials with various morphologies have been synthesized in a cationic polyelectrolyte‐controlled mineral solution. Investigations showed that the mineral solution initially underwent a phase separation to produce a condensed liquidlike amorphous intermediate. This ...


Effect of fluid velocity on radioactive ion retention by fluidized bed reactor

21-Feb-2015 | Mohamed Abdelaziz, Azza H. Ali, Hesham F. Elbakhshawangy, Sameh H. Othman, The Canadian Journal of Chemical Engineering, 2015

This study is concerned with the design, construction, simulation, and pre‐operation of a fluidized bed reactor for low level radioactive waste treatment by a new chelating resin. In this respect a new mathematical model is suggested to account for the effect of fluid velocity and to determine ...


Exciton Structure and Dynamics in Solution Aggregates of a Low-Bandgap Copolymer

20-Feb-2015 | Zhi Guo; Doyun Lee; Haifeng Gao; Libai Huang, Journal of Physical Chemistry B, 2015

In this work, we elucidate exciton structure, dynamics, and charge generation in the solution phase aggregates of a low-bandgap donor–acceptor polymer, poly(4,8-bis-alkyloxybenzo[1,2-b:4,5-b′]dithiophene-2,6-diyl-alt-(alkylthieno[3,4-b]thiophene-2carboxylate)-2,6-diyl (PBDTTT). The polymer ...


Phase Equilibrium for the Ternary System KH2PO4 + NaH2PO4 + H2O at 303.15 K

17-Feb-2015 | Si Shen; Jian-hua Tang; Zhong-hua Liu; Li-quan Kang; Dun Mao, Journal of Chemical & Engineering Data, 2015

The phase equilibrium of the ternary system (KH2PO4+ NaH2PO4 + H2O) at 303.15 K was investigated by a combination of the isothermal solution saturation method and the moist residues method. The solid phase formed in the equilibrium state was verified by X-ray diffraction (XRD). A phase diagram ...


Bifunctional Cyclam‐Based Ligands with Phosphorus Acid Pendant Moieties for Radiocopper Separation: Thermodynamic and Kinetic Studies

03-Feb-2015 | Monika Paúrová, Jana Havlíčková, Aneta Pospíšilová, Miroslav Vetrík, Ivana Císařová, Holger Stephan, Hans‐Jürgen Pie ..., Chemistry - A European Journal, 2015

Abstract Two macrocyclic ligands based on cyclam with trans‐disposed N‐methyl and N‐(4‐aminobenzyl) substituents as well as two methylphosphinic (H2L1) or methylphosphonic (H4L2) acid pendant arms were synthesised and investigated in solution. The ligands form stable complexes with transition ...


Analytical form of forces in hydrophobic collapse

04-Jan-2015 | Author(s): J. Chakrabarti , Suman Dutta, Chemical Physics Letters, 2015

Publication date: 20 January 2015 Source:Chemical Physics Letters, Volume 620 Author(s): J. Chakrabarti , Suman Dutta We derive an analytical form for the effective interaction forces between two solvophobic solutes, mediated by the solvent. The effective force is attractive for short ...
